[00:00:00] <ssi> I have a cnc machine that makes lasagna
[00:00:01] <zeeshan> i naturally eat curry
[00:00:01] <renesis> green curry > all curry
[00:00:02] <zeeshan> but i cant make it
[00:00:13] <ssi> it's called a microwave
[00:00:17] <ssi> you put a stouffers box in it
[00:00:20] <ssi> and out comes lasagna
[00:00:24] <renesis> ssi: do you isolate your cheese and sauce layers?
[00:00:35] <renesis> or do you layer sauce onto cheese
[00:00:50] <ssi> renesis: lol I never considered it
[00:00:55] <renesis> if you just stouffers it you do not isolate
[00:01:02] <ssi> then there's your answer
[00:01:04] <renesis> but stouffers is pretty good shit
[00:01:10] <ssi> yeah it really is hehe
[00:01:13] <renesis> i isolate
[00:01:22] <ssi> dammit now you're making me wish I'd brought stouffers lasagna instead of chickin pot pie
[00:01:37] <XXCoder1> garfield loves em
[00:01:44] <renesis> garfield knows whats up
[00:01:53] <furrywolf> my internet connection seems to be sucking too badly to participate in conversations. "��� CTCP PING reply from furrywolf: 109.089 seconds"
[00:02:04] <ssi> lame
[00:02:15] <renesis> thats what my shell is like sometimes

[00:02:30] <XXCoder1> ssi: awesome but whats up with nazi getup
[00:02:42] <ssi> they were german recon planes
[00:02:52] <ssi> fieseler storch
[00:03:20] <furrywolf> hrmm, you don't want curry... how about pho? pho is good. :P
[00:03:21] <renesis> im totally doing bacon fried rice once dishes are clean
[00:03:29] <ssi> BACON FRIED RICE!?
[00:03:30] <renesis> pho is good but bun is better
[00:03:31] <XXCoder1> sraracha
[00:03:55] <renesis> bun with beef w/ cutup egg rolls is how i test vietnamese place
[00:04:12] <renesis> (bun is vermicelli noodle salad)
[00:04:33] <renesis> ssi: whats wrong with bacon fried rice?
[00:04:44] <ssi> the fact that I have none in front of me, obviously
[00:04:48] <renesis> bacon and toasted almond fried rice is better but i dont have almonds
[00:05:02] <ssi> I'm coming over to your house for dinner from now on
[00:05:02] <renesis> but i has onions and eggs
[00:05:25] <renesis> cool because its hard to cook cheap for 1
[00:05:41] <renesis> i always make too much rice because wtf is a half cup of rice
[00:05:54] <ssi> heheh

[00:06:02] <ssi> cooking for one is very hard
[00:06:07] <ssi> I've never been good at it w
[00:06:11] <XXCoder1> I dont bother
[00:06:12] <renesis> and beans i gotta make a weeks worth because its like a 3 hour drama to cook beans
[00:06:15] <XXCoder1> I just drink soylent
[00:06:18] <ssi> which is why I eat a lot of fast food and frozen dinners :(
[00:06:19] <XXCoder1> boom all what I need
[00:06:32] <renesis> i kind of want to try one of the soylents
[00:06:40] <XXCoder1> one flaw is that it takes long time to get first order
[00:06:41] <renesis> not actual soylent tho, i dont think
[00:06:46] <XXCoder1> then finally can get em
[00:06:48] -!- TTN [TTN!~TTN@unaffiliated/ttn] has joined #linuxcnc
[00:07:08] <XXCoder1> renesis: one tip, first order just order one week worth
[00:07:15] <furrywolf> bbl, errands
[00:07:19] <XXCoder1> if its fine prder month worth and it will take only week say
[00:07:19] <ssi> "f you are a real experimenter, have an airframe that has superb engine out/off field capabilities, have another airplane to actually fly (if that is a goal), don’t mind tinkering for the next 5-6 years, and don’t mind throwing it all away in the end, the Egg engine might be an acceptable starting point. If it were me, I would stay away from them. (my apologies to the guys that are trying to unload these FWF packages)"
[00:07:24] <renesis> i was going to try 100% food or something similar
[00:07:25] <ssi> lol
[00:08:38] <renesis> i tried carne asada from trader joes
[00:08:44] <renesis> fuckin $8/lb
[00:08:49] <andypugh> Quiche in oven. Watch TV, put salad stuff on a plate, get quiche out of oven. Meal. (not a Real Man meal though)
[00:08:53] <XXCoder1> trader joe is ripoff
[00:08:54] <renesis> but yeah, definitely tastey
[00:09:02] <renesis> how is trader joes a ripoff?
[00:09:09] <renesis> its usually cheaper than normal supermarket
[00:09:19] <renesis> whole foods is kind of a ripoff
[00:09:41] <XXCoder1> hmm remembered em as ripoff but may be misremembering with whole foods
[00:09:56] <ssi> all food is a ripoff
[00:09:57] <ssi> hahaha
[00:09:58] <renesis> usually people who say trader joes is a ripoff dont shop there
[00:10:11] <renesis> i go there because the only shit cheaper is the absolute cheapest shit at reg market
[00:10:15] <XXCoder1> ssi: soylent isnt bad, around $3.5 each meal usd
[00:10:15] <renesis> and not even then, sometimes
[00:10:29] <renesis> its like $300-400 month
[00:10:30] <ssi> XXCoder1: does it taste horrible?
[00:10:32] <renesis> 3 meals
[00:11:01] <XXCoder1> ssi: its netual really. you need to add stuff to make it nasty
[00:11:04] <XXCoder1> tasty
[00:11:08] <XXCoder1> either way you like
[00:11:12] <ssi> haha
[00:11:18] <zeeshan> i think im gonna make some garlic shrimp
[00:11:18] <ssi> "mmmm, let's make it nasty"
[00:11:25] <zeeshan> doesnt feel like enough food :/
[00:11:31] <zeeshan> is there a side that typically goes with it?
[00:11:34] <XXCoder1> I usually use milk chocuate powder to make it yummy
[00:11:44] <ssi> zeeshan: pasta maybe
[00:11:54] <renesis> or do rice with the shrimp broth
[00:12:00] <zeeshan> plain rice?
[00:12:01] <renesis> and lots of butter
[00:12:02] <ssi> renesis loves his rice
[00:12:05] <zeeshan> lol
[00:12:10] <renesis> rice is fast and cheap yo
[00:12:11] * XXCoder1 hates butter
[00:12:14] <ssi> indeed
[00:12:20] <renesis> so is pasta, shrimp sucks tho

[00:12:25] <ssi> haha
[00:12:30] <malcom2073> I miss shrimp
[00:12:32] <renesis> only bacon fat > butter
[00:12:37] <ssi> :D
[00:12:40] <malcom2073> Got allergic to my favorite food suddenly two years ago
[00:12:44] <XXCoder1> ssi: actuall I do like butter but like I said..
[00:12:49] <ssi> I used to be allergic to shrimp
[00:12:52] <ssi> and grew out of it I guess
[00:12:57] <XXCoder1> malcom2073: try allegric to my most favorite fruit of all
[00:12:59] <XXCoder1> lemon
[00:13:00] <ssi> cause i ate shrimp on my sailing trip in december and didn't die

[00:13:05] <XXCoder1> and second, orange

[00:13:36] <ssi> "One airplane I heard about in Camarillo, CA had a very minor problem with an injector or spark plug, and the engine's computer went into the "limp home" mode, where it only made 25% power, and lit up the "service engine light". This was apparently not a welcome event just after he took off, so the airplane slowly settled back into a farm field with the pilot unable to do anything but not turn the airplane and sit there screaming. Lesson learned: disabl
[00:13:39] <XXCoder1> minor one, headaches and bit dizzy but yeah
[00:13:45] <malcom2073> I'm ok with that, I can't eat citrus anyway, mouth swells up from the acidity
[00:13:48] <andypugh> I already am allergic to prawns (which are exactly the same thing in a different dialect)
[00:13:53] <XXCoder1> lol ok
[00:14:13] <XXCoder1> disable...
[00:14:25] <ssi> andypugh: haha
[00:14:33] <malcom2073> andypugh: aren't prawns crayfish?
[00:14:56] <CaptHindsight> sea spiders?
[00:15:02] <andypugh> No, pwawns are just big shrimps.

[00:21:45] <malcom2073> Most of these places are pickup trucks on the side of the road, I never went all the way down to the harbor, live crabs are live crabs
[00:21:52] <malcom2073> at least in MD
[00:21:55] <andypugh> Buy scuba gear and eat them raw underwater :-)

[03:50:18] <zeeshan> -14.8 f
[03:50:32] <Jymmm> It was 78F here today, I was running around in shorts and sandals.
[03:50:32] <zeeshan> weather.ca says feels like -35
[03:50:44] <Jymmm> 90F in SoCal
[03:51:05] <PetefromTn_> we got pretty damn cold here last night down into the single digits
[03:51:06] <Jymmm> Yes, i know, I'm a bastard =)
[03:51:46] <PetefromTn_> it is supposed to get even colder tonight and we are apparently getting a lot of precipitation that will be an icy wintery mix which sucks pretty bad.
[03:51:51] <zeeshan> pete
[03:51:59] <zeeshan> i didnt know it got cold in the south :P
[03:52:05] <zeeshan> mid south :p
[03:52:07] <PetefromTn_> yeah I know right
[03:52:18] <PetefromTn_> we usually only get a couple days a year of this stuff
[03:52:29] <zeeshan> lol
[03:52:29] <PetefromTn_> but this is supposed to be pretty bad they are predicting
[03:52:34] <zeeshan> its 0C in memphis
[03:52:38] <zeeshan> :P:p
[03:52:45] <PetefromTn_> at least the kids are out of school for the next two days
[03:53:04] <PetefromTn_> I probably should just go get the kerosene in case the wires freeze and we loose power
[03:53:22] <PetefromTn_> lose
[03:53:27] <zeeshan> yea
[03:53:31] <zeeshan> better to be safe than sorry
[03:54:02] <PetefromTn_> well like I said my non electric kerosene heater is totally full and my can is able halfway
[03:54:19] <PetefromTn_> I wish I had another can I could empty it into and refill the big can completely
[03:54:26] <Tom_itx> PetefromTn_ how's that global warming feelin about now?
[03:54:33] <PetefromTn_> heh right
[03:54:37] <zeeshan> one thing i dont understand is
[03:54:42] <zeeshan> if the winter solstics is like december something
[03:54:47] <zeeshan> why does it get so cold in feb?
[03:54:52] <PetefromTn_> Oh wait I know I can fill up my electric kerosene heater that dies on me
[03:54:52] <zeeshan> if we're physically getting less light
[03:54:56] <zeeshan> is it something to do w/ the distance?
[03:55:05] <PetefromTn_> died on me
[03:55:17] <PetefromTn_> and then fill the bottle completely
[03:55:35] <PetefromTn_> I have a kerosene suction pump for removing it from the other heater if I need to..
[03:55:41] amnesic is now known as amnesic_away
[03:56:43] <PetefromTn_> ya know it's funny the other day I watched that movie Brick mansions or whatever it was called with Paul Walker and all that free running stunts
[03:56:54] <zeeshan> that movie was pretty good

[04:05:05] <PetefromTn_> I am talking about the District 13 compared to Brick Mansions.. it is the same damn movie LOL..
[04:05:09] <zeeshan> oh
[04:05:21] <PetefromTn_> instead of Paul Walker there is some shaved head french guy...
[04:05:48] <PetefromTn_> and instead of the black drug dealer guy there is a guido looking white guy...
[04:05:54] <zeeshan> lol
[04:07:01] <PetefromTn_> with subtitles heh
[04:08:27] <zeeshan> pete
[04:08:30] <zeeshan> have you watched the sphere?
[04:08:34] <zeeshan> "the sphere"
[04:08:40] <zeeshan> if you like sci fi movies
[04:08:41] <ssi> as opposed to "sphere"?
[04:08:42] <PetefromTn_> no I don't think so.
[04:08:43] <zeeshan> thats a good one
[04:08:46] <zeeshan> i highly recommend it
[04:08:52] <zeeshan> and another one is
[04:08:53] <zeeshan> "the abyss"
[04:08:59] <PetefromTn_> We watched a kevin Costner movie earlier
[04:09:02] <zeeshan> which one?
[04:09:03] <PetefromTn_> 3 days to die
[04:09:05] <zeeshan> hes awesome
[04:09:07] <PetefromTn_> it was pretty good
[04:09:10] <zeeshan> ah
[04:09:14] <zeeshan> i love his coastguard movie
[04:09:19] <PetefromTn_> I will see if sphere is in there

[04:09:28] <furrywolf> argh! too heavy!
[04:09:31] <PetefromTn_> I was IN the Coast Guard...
[04:09:35] <zeeshan> nice!
[04:09:44] <furrywolf> I decided to buy the planer. checked the manual, 460lbs.
[04:09:48] <ssi> PetefromTn_: did I tell you about getting interdicted by the coast guard on the gulf when I was on my sailing trip?
[04:09:58] <furrywolf> having someone to help unload would have made it much easier.
[04:10:03] <PetefromTn_> yeah you posted it on Facebook as I recall
[04:10:06] <ssi> heheh
[04:10:10] <ssi> those bastards are fast!
[04:10:37] <PetefromTn_> they have some fast boats most are just the motor lifeboat style.
[04:10:37] <ssi> it was one like this
[04:10:37] <ssi> http://www.davesems.com/files/USHLScggun.jpg
[04:10:48] <PetefromTn_> Oh an RHI
[04:10:51] <furrywolf> ssi: I solved the subaru airplane engine problem.
[04:11:09] <ssi> furrywolf: I hope your solution was "sell the subaru, buy a lycoming" ;)
[04:11:09] <PetefromTn_> we used to use the smaller version as a small boat to do boardings from our Coast Guard Cutter.
[04:11:51] <furrywolf> ssi: nope. subaru diesel! it has all the power at perfectly prop-matching rpms. :P
[04:11:54] <PetefromTn_> http://www.uscg.mil/pacarea/cgcsteadfast/img/ste_02.jpg I lived and served aboard this vessel for 2.5 years
[04:11:55] <furrywolf> and you can run it on jet-a.
[04:12:01] <ssi> getting closer
[04:12:07] <ssi> there are still problems though
[04:12:26] <ssi> the crank and thrust bearing probably won't hold up to airplane use
[04:12:47] <ssi> direct drive you have the entire static thrust pulling on the thrust bearing
[04:12:55] <ssi> plus there's the gyroscopic loads of the prop itself, which are significant
[04:13:26] <ssi> the front bearing in a lycomic is HUGE
[04:13:27] <furrywolf> hrmm. no idea what kind of thrust bearings it has. could probably rig up a couple bearings and a shaft coupler, or use a fixed-speed prop that already has bearings built into the hub around the hydraulic seals...
[04:14:07] <zeeshan> PetefromTn_: what did you do
[04:14:10] <zeeshan> rescue missions?
[04:14:11] <furrywolf> you'd probably only need to add one bearing actually, and just adjust it well.
[04:14:13] <ssi> redrive would be necessary, and then you're adding the same sort of torsional resonance problems that led to issues with the PSRUs in the first place
[04:14:36] <ssi> trust me, you're not the first person to have this idea
[04:14:39] <PetefromTn_> yeah, rescue missions, drug interdiction, fisheries patrols...
[04:14:40] <ssi> we've talked about it at length
[04:14:45] <zeeshan> nice
[04:14:48] <zeeshan> which water body
[04:15:11] <furrywolf> someone else wanted to use the subaru diesel? most people don't know they exist...
[04:15:17] <ssi> not the subaru diesel
[04:15:21] <ssi> bmw diesel
[04:15:23] <ssi> vm diesel
[04:15:26] <ssi> it's been discussed

[04:15:42] <ssi> three bearings
[04:15:48] <ssi> two regular mains and the front, which is like 4" long

[04:16:37] <ssi> zeeshan: all jets run on diesel :P
[04:16:46] <ssi> there are diesel aircraft engines out there
[04:16:51] <ssi> thielert makes the most popular
[04:17:05] <zeeshan> lol
[04:17:07] <PetefromTn_> The USCGC Steadfast was patrolling the caribbean out of St. Petersburgh, Florida port
[04:17:08] <furrywolf> so bolt a pair of tapered roller bearings to the bellhousing, with a preload nut (with appropriate safety wire, etc), and shims to position it within the engine's endplay.
[04:17:26] <ssi> the diamond DA-42 twinstar uses thielert diesels
[04:17:30] <ssi> and it's a pile of problems
[04:17:34] <ssi> friend of mine did his multi training in one
[04:17:37] <PetefromTn_> It has since been decomissioned, redone, and recommissioned and it is now apparenlty up in washington state
[04:17:41] <zeeshan> um wtf
[04:17:43] <ssi> multi training consists of ten or so hours of simulated engine failures
[04:17:47] <zeeshan> you know those 1 plug into 3
[04:17:49] <zeeshan> things ?
[04:17:52] <zeeshan> mine just blew the fuck up
[04:17:53] <zeeshan> wtf
[04:17:55] * furrywolf realizes this looks remarkably like a car wheel hub, available from same donor vehicle. :P
[04:18:03] <ssi> the only thing tha makes a multi different than a single is what happens when an engine fails
[04:18:12] <ssi> well, he had three REAL engine failures in ten hours in a twinstar
[04:18:22] <ssi> one of them happened while he had the other one shut down and was landing
[04:18:25] <furrywolf> now I have got to bolt a wheel hub onto the back of an engine just to show it can be done. :P

[04:19:21] <ssi> furrywolf: it can be done, just remember that it has to be able to support a 600lb aluminum disk that's trying to bend 90 degrees away from the plane of rotation
[04:19:32] <PetefromTn_> I think I saw that Sphere movie actually Dustin Hoffman etc..
[04:19:39] <furrywolf> ssi: they can support a car being driven by rednecks on dirt roads.
[04:19:41] <zeeshan> yes PetefromTn_
[04:19:42] <zeeshan> tis old
[04:19:56] * furrywolf is such a redneck, and has bounced cars over plenty of waterbars at speed
[04:20:01] <ssi> yes but that's plain radial load
[04:20:05] <ssi> gyroscopic load is ugly
[04:20:08] <PetefromTn_> Good movie but I can't remember the story right offhand.
[04:20:15] <furrywolf> no different than when you crank the steering wheel around hard
[04:20:32] <zeeshan> ssi:
[04:20:36] <zeeshan> is this regarding using a subie engine
[04:20:38] <zeeshan> for a plane?
[04:20:38] <furrywolf> there's enough force on a sharply cornering car wheel to easily snap a prop at the hub.
[04:20:44] <zeeshan> or diesel engines?
[04:20:45] <ssi> zeeshan: yeah he's really hung up on it
[04:20:54] <zeeshan> well if you thrust is a big problem
[04:20:57] <furrywolf> nah, now I'm mostly just being annoying. :)
[04:20:59] <zeeshan> cant you buyild an adapter bearing
[04:20:59] <ssi> even though dozens of people have lost their airplanes and some their lives trying it
[04:21:02] * furrywolf can't afford to actually build a plane
[04:21:12] <zeeshan> for the extra loading
[04:21:18] <zeeshan> to reduce the loading on the crank
[04:21:24] <ssi> zeeshan: you can, but torsional resonances are an issue
[04:21:31] -!- ve7it [ve7it!~LawrenceG@S01060014d19d0b68.pk.shawcable.net] has joined #linuxcnc
[04:21:44] <ssi> and it's extra complexity
[04:21:50] <zeeshan> torsional resonance
[04:21:52] <furrywolf> from what I keep hearing about here, your standard GA engine is WORSE. we just has a pilot die a month or two ago after an engine failure, think it was in a cessna...
[04:21:57] <ssi> you know what else you could do? just design your engine for the application in the first place
[04:21:57] <zeeshan> as in a natural ferquency mode
[04:22:01] <zeeshan> thjat goes in twisting the crank ?
[04:22:12] <zeeshan> back and forth
[04:22:28] <zeeshan> yea, for air planes that makes the most sense
[04:22:30] <ssi> zeeshan: yes, there's complicated interplay between cylinder impulses and prop blade loading
[04:22:32] <zeeshan> retrofitting seems dangerous :P
[04:22:43] <furrywolf> so who wants to help me move this planer? it's 460lbs. I unloaded it from the car (subaru!) by myself, but it sucked.
[04:23:12] <ssi> zeeshan: they already exist direct drive, when you couple a redrive in the middle there's extra frequency modes to deal with
[04:23:19] <zeeshan> yea
[04:23:20] <zeeshan> extra dof
[04:23:43] <ssi> airplane engines have the crank desigcned to directly drive a prop, and have appropriate bearings for that load
[04:23:47] <ssi> car engines simply don't
[04:23:49] -!- Crom_ has quit [Ping timeout: 252 seconds]
[04:23:55] <ssi> they're designed to drive something via a spline
[04:23:59] <zeeshan> yea
[04:24:17] <ssi> so they have radial loads only, no significant thrust loads or bending loads
[04:25:01] <ssi> a 60lb prop is a huge gyroscope with a lot of energy, and if you perform a quick pitch up maneuver for instance, you get very large precession bending moments on the crank flange
[04:25:02] <furrywolf> airplane engines also cost more than the entire plane I'd be considering.
[04:25:14] <ssi> they cost less than a PSRU for a subaru
[04:25:35] <furrywolf> right, which is why I thought of a low-rpm subaru motor. :P
[04:25:59] <ssi> how low
[04:26:36] <furrywolf> peak torque is 1800rpm, trying to find a power curve but not seeing one.
[04:26:52] <ssi> how much power at 2700rpm
[04:27:05] <ssi> and how much does the engine weigh
[04:27:16] <ssi> and how much would the cooling system weigh, including the coolant
[04:28:13] <furrywolf> http://rototest-research.eu/spec/view/png/graph/STR-08100601-kW-Nm-C.png like that, apparantly. 2700rpm approximately 95kw, or 130-ish hp.
[04:28:38] <furrywolf> actually, that's measured at the rear wheels, engine output will be higher.
[04:29:14] <furrywolf> the upper grey line I guess is estimate at engine
[04:29:16] <ssi> ok let's be generous and say it's comparable to a 150hp O320
[04:29:39] <furrywolf> no, the grey line is subaru's published spec. my bad.
[04:30:19] <furrywolf> that's a '08, they've improved them a little since then.
[04:30:27] -!- Crom_ [Crom_!~Robi@pool-108-23-106-180.lsanca.fios.verizon.net] has joined #linuxcnc
[04:31:43] <ssi> how much is it going to cost to acquire the engine?
[04:31:47] <ssi> how much does it weigh
[04:32:05] <ssi> how much is it going to cost to build a redrive for it
[04:32:19] <furrywolf> not finding a weight... one person estimates 300lbs, which seems a little heavy.
[04:32:26] <ssi> sounds about right
[04:32:31] <ssi> diesels are heavy
[04:32:35] <ssi> iron blocks generally
[04:32:57] <ssi> what's the displacement on it?
[04:33:14] <furrywolf> ok, found a spec saying it's 380lbs complete including exhaust. would be stripping a lot of that off for non-car use. don't need a/c, etc.
[04:33:30] <furrywolf> and probably a much much simpler exhaust, without particulate filter and cats...
[04:33:35] <furrywolf> 2.0L
[04:33:48] <ssi> does that include cooling system?
[04:33:49] <furrywolf> it's all aluminum. I don't know if subaru ever made an iron engine. :)
[04:33:51] <ssi> probably not
[04:34:08] <ssi> let's call it a wash and say teh cooling system INCLUDING COOLANT will weigh what the stuff you removed did
[04:34:25] <ssi> O320 is 244lb dry
[04:34:35] <ssi> so you're 136lb heavier right from the start
[04:35:07] <ssi> if you scrounge (and considering you built your airplane from scrap metal, I'd say that's likely), you can get a perfectly serviceable O320 for about $3000
[04:35:36] <ssi> I paid twice that for a 200hp anglevalve IO360
[04:35:48] <ssi> which is the most expensive lycoming 4cyl in existence
[04:35:53] <ssi> they're about 60k new
[04:36:38] <ssi> so anyway, I dunno how much your subie diesel (which doesn't exist in the US) cost you to acquire
[04:36:54] <ssi> and I dunno how much time and effort and money goes into building the redrive to make it suitable to drive a prop
[04:37:13] <ssi> but I do know that now you're trusting your safety to a redrive that you designed and built
[04:37:19] <ssi> I hope you at least got zeeshan to look over the design
[04:37:24] <ssi> since everyone knows he's the ace ME
[04:37:46] <furrywolf> how much do you save with the lower fuel requirements? kerosene is marginally heavier than avgas, but you might get rather impressively low fuel consumption. on a thread on a diesel conversion done to a cessna, consumption dropped from 11gph to 8gph...
[04:38:11] <ssi> O320s only burn 7-8gph to begin with
[04:38:31] <furrywolf> also, no fair comparing a dry weight to a wet weight. :P
[04:38:52] <ssi> was your weight wet weight?
[04:38:57] <ssi> cause the only difference in a lyco is the oil
[04:39:00] <ssi> it's air cooled remember
[04:39:12] <ssi> I figured your number was dry also, wrt oil
[04:39:27] <ssi> here's where it gets fun
[04:39:44] <ssi> the CH701 is nominally 580lb empty, 1100lb gross
[04:39:58] <ssi> and that's with a 185lb engine
[04:40:10] <ssi> so your engine will weigh TWO HUNDRED POUNDS more
[04:40:15] <ssi> which means you can take one fewer passenger :D
[04:40:44] <furrywolf> heh
[04:40:45] <ssi> your engine will add almost 50% to the empty weight of the airplane
[04:41:08] <furrywolf> the ch701 also has a big warning not to use an engine over 100hp, and says it's fine at 50hp, so it's obviously more suited to a larger plane.
[04:41:22] <ssi> sure, so let's say RV6 instead
[04:41:28] <ssi> I've been flying an RV6 with a 150hp O320 on it
[04:41:37] <ssi> it's 980lb empty, 1600lb gross
[04:41:46] <ssi> still adding 20% to the empty weight
[04:41:56] <ssi> as an amusing anecdote
[04:42:07] <ssi> with the lyco it does 155kt on 150hp
[04:42:14] <furrywolf> the ch701 I like because it's the only plane I've seen that looks like it can be built with exactly zero specialist tools.
[04:42:14] <ssi> it was originally built as a subaru
[04:42:27] <ssi> and according to the records he registered it with the horsepower listed as 400
[04:42:44] <ssi> according to the owner, the original builder said it never flew faster than 117kt
[04:43:05] <PetefromTn_> well I better go get this kerosene filled BBL
[04:43:11] <furrywolf> ... 400 from a subaru motor?
[04:43:19] <ssi> yea I dunno, that's just how he registered it :)
[04:43:27] <ssi> either way, 117kt in an RV is absurdly slow
[04:43:33] <ssi> I blame the radiators in the lower wing skins
[04:43:49] <ssi> 155kt in the RV6 is actually on the slow side
[04:43:56] <ssi> it's a simple build, fixed pitch wood sterba prop
[04:44:00] <ssi> 150hp
[04:44:12] <ssi> my RV7 is set up 200hp, constant speed hartzell, and I expect 185-190kt
[04:44:47] <ssi> anyway... I'm honestly not trying to piss in your cheerios
[04:44:54] * furrywolf expects not to be able to afford any of them
[04:44:59] <ssi> there are people out there who have built and flown subie powered planes
[04:45:06] <ssi> and some of those people are happy with them
[04:45:20] <ssi> but LOTS of those people are not happy with them
[04:45:22] <furrywolf> yeah, found one guy saying he's got 1300hrs on it with no work whatsoever...
[04:45:26] <ssi> and some of them are dead
[04:45:44] <ssi> same goes for LS1 conversions
[04:45:55] <ssi> the best auto conversions out there are the corvair and aerovee and such
[04:46:14] <furrywolf> I'd never put a chevy in an airplane. I like staying in the air. :P
[04:46:20] <ssi> same here
[04:46:24] <ssi> but I also say the same thing about subies :)
[04:46:31] <ssi> and like I said earlier, it's no knock against subaru
[04:46:35] <ssi> they build a decent engine
[04:46:41] <ssi> but they don't build airplane engines
[04:46:45] <ssi> I bet if they did, they'd be excellent
[04:47:04] <ssi> but they build engines which are suited to a task that is drastically different than the conversions use them for
[04:47:10] <ssi> already harped on bearing issues
[04:47:15] <ssi> there's also duty cycle issues
[04:47:25] <ssi> a lyco will run 100% power for 2000 hours in really shitty adverse conditions
[04:47:29] <ssi> will a subie?
[04:47:41] <furrywolf> yes. :)
[04:47:45] <ssi> you sure about that?
[04:47:55] <furrywolf> I've lugged mine up enough hills 8 hours a day...
[04:48:11] <furrywolf> I used to drive an ea81 1000mi/week in the hills.
[04:48:16] <ssi> I seriously doubt you actually managed to lug up a hill without stopping at >75% power for 8 hours
[04:48:24] <ssi> because that's exactly what airplane engines do
[04:48:33] <furrywolf> no, but 30 mins, yes.
[04:48:37] <ssi> not the same
[04:49:06] <ssi> most airplane engines will go five or six or eight hours at 75% power and not reduce below tchat til it's time to land
[04:49:12] <ssi> and that's standard operating profile
[04:49:13] <furrywolf> yes, I know this.
[04:49:30] <ssi> they're huge bore, low-rpm, high clearance engines
[04:49:37] <ssi> they're extremely simple
[04:49:44] <ssi> no electrical requirement whatsoever

[04:50:08] <furrywolf> hrmm, yeah, the diesel has some pretty steep electrical...
[04:50:09] <ssi> and that's why we have two of them :)
[04:50:11] <ssi> and check them every flight
[04:50:39] <Valen> you know I would rate a modern electrical engine against many aero engines in terms of reliability
[04:50:52] <furrywolf> of course, it's no worse than fadec... except automotive grade isn't quite aerospace grade when it comes to testing. :)
[04:51:09] <ssi> the thielert issues I was talking about earlier were largely related to fadec
[04:51:11] <SpeedEvil> And it all doesn't help if the pilots turn off the wrong one.
[04:51:21] <ssi> its fadec system shuts the engine down if any abnormal condition arises
[04:51:25] <ssi> which is not a good thing in an airplane
[04:51:28] <furrywolf> Valen: I would too. you're always hearing about light airplanes having engine failures, despite having very expensive purpose-built engines.
[04:51:46] <Valen> I think much of the issue is with them getting pulled apart all the time
[04:52:00] <furrywolf> as I said earlier, we had a pilot die here a month or two ago due to an engine failure... he tried ditching in a river and didn't make it.
[04:52:05] <ssi> yeah they don't usually run news stories about the cessna that went 4000 hours without an overhaul

[04:52:19] <ssi> not even on slow news days :P
[04:53:30] <ssi> here's a fun stat
[04:53:46] <ssi> However, most NTSB accident reports list the type of engine. We can easily determine how often a loss of power was the cause of the accident, and compare the rates for traditionally powered aircraft with those mounting auto-engine conversions. Obviously, a higher percentage means a higher relative number of engine failures.
[04:53:48] <furrywolf> most engine failures are due to forgetting to add fuel? :P
[04:53:48] <Valen> but an automotive engine doing 4000 hours (200,000km / 50km/hr) without anything more than oil and plugs is a non event
[04:53:51] <ssi> While we’re at it, let’s show the two-stroke engine results as well.
[04:53:54] <ssi> Traditional Aircraft Engines: 12.2%
[04:53:54] <ssi> Two-Stroke Engines: 28.9%
[04:53:54] <ssi> Auto Engine Conversions: 30.5%
[04:54:23] <Valen> I'm not saying to use an auto engine in a plane, in drop in type conversion
[04:54:45] <ssi> it's just not apples to apples
[04:55:04] <ssi> 4000 hours in an airplane is a lifetime
[04:55:05] <ssi> literally
[04:55:08] <Valen> I was suggesting updating an aero engine with fuel injection, VCT, all those good things wouldn't inherently be a bad thing
[04:55:15] <ssi> my 1973 cherokee has about 4000 hours total time on the airframe
[04:55:24] <ssi> they've had fuel injection since the 30s
[04:55:30] <ssi> VCT isn't useful in an airplane engine
[04:55:34] <ssi> even the subie guys rip it out
[04:56:01] <Valen> I guess if you sit at the one RPM all the time
[04:56:04] <ssi> about the only significant upgrade to current airplane engines is electronic ignition
[04:56:08] <ssi> exactly
[04:56:23] <Valen> why would electronic ignition be better than a magneto at a fixed RPM?
[04:56:35] <ssi> because magnetos have fixed timing
[04:56:44] <furrywolf> 4000 is a lifetime? the ones at work all have >30000...
[04:56:44] <ssi> airplane engines don't run at a fixed RPM, they run at constant RPM
[04:56:46] <ssi> it's not the same :)
[04:57:05] <ssi> furrywolf: let me know when you've surpassed 4000 hours
[04:57:16] <Valen> what is the difference?
[04:57:32] <furrywolf> of course, they've been through more than a few rebuilds... one of them they let get so bad that on a still day, you could see exactly where it taxied by the opaque blue trail...
[04:57:58] <ssi> Valen: running 2500rpm for two hours, then running 2300rpm
[04:58:00] <ssi> for two hours
[04:58:15] <ssi> it didn't run "at a fixed rpm", it ran at several different rpms
[04:58:26] <Valen> VCT would help then ;-P
[04:58:26] <ssi> but the speed was constant for the duration
[04:58:35] <ssi> not enough to justify the complexity
[04:58:57] <ssi> electronic ignition has proven gains
[04:59:07] <ssi> hotter spark, finer control over timing for EGT and power
[04:59:08] <Valen> heres one I've always wondered, why don't they run mufflers on the exhaust of light aircraft?
[04:59:12] <ssi> teh ability to run auto plugs
[04:59:18] <ssi> most have mufflers
[04:59:20] <ssi> some don't
[04:59:47] <ssi> my cherokee has one stock, mine's ben upgraded with an aftermarket exhaust with tuned muffler that adds a fair bit of power
[04:59:54] <ssi> my rv has no muffler, striaght four pipe exhaust
[04:59:57] <ssi> and it's loud as balls
[05:00:02] <Valen> one to make it quieter i mean ;-P
[05:00:14] <ssi> it's not a loudener :P
[05:00:15] <Valen> the ones I've seen all seem to just have the 4 pipes ;->
[05:00:16] <ssi> it's a muffler
[05:00:41] <ssi> which ones have you seen? :P
[05:01:06] <Valen> mostly cesnas from a decade ago when I did my student pilots licence ;->
[05:01:37] -!- PetefromTn_ has quit [Ping timeout: 255 seconds]
[05:01:43] <ssi> I am pretty sure 172s have mufflers
[05:02:08] <ssi> http://i764.photobucket.com/albums/xx287/DRW-33/DSC01010.jpg
[05:02:36] <Valen> I have been pondering an aircraft, (experimental) for speed and giggles
[05:02:45] <ssi> do it
[05:03:01] <ssi> experimental is the way to go
[05:03:21] * furrywolf thinks aircraft are still reserved for rich people
[05:03:22] <Valen> lightweight auto engine + modest battery pack (15 minutes or so flight time) and electric powered props
[05:03:31] <Valen> prop rather
[05:03:37] -!- Tanz [Tanz!~chatzilla@conr-adsl-209-169-103-164.consolidated.net] has joined #linuxcnc
[05:03:40] <ssi> battery pack?
[05:03:41] <furrywolf> hybrid offers no benefit to airplanes
[05:04:07] <ssi> agreed
[05:04:09] <furrywolf> hybrid is good for frequent speed and power changes. see above discussion about keeping constant rpm hours at a time.
[05:04:09] <Valen> the idea was for it to be quiet getting on and off the ground so as not to upset the neighbours
[05:04:09] <ssi> think energy density
[05:04:22] <ssi> half the noise is the prop
[05:04:30] <Valen> right, so its half the noise ;->
[05:04:38] <Valen> but thats not the giggles part
[05:04:43] <ssi> get better neighbors :P
[05:04:50] <furrywolf> I think more than half is the prop...
[05:05:07] <Valen> the giggles part would be when you fire up the ramjet ;->
[05:05:28] <Valen> did i mention making the thing out of stainless?
[05:05:32] <ssi> https://www.youtube.com/watch?v=yf2gquYDBss
[05:05:52] <ssi> sonex makes some ugly ass airplanes :)
[05:06:04] <Valen> that is ugly
[05:06:17] <furrywolf> jet airplanes have a history of dead test pilots. just saying.
[05:06:18] <Valen> and it has a terrible rattle there
[05:06:29] <ssi> it's not much quieter than an equivalently powered gas burner
[05:06:29] <furrywolf> ramjet
[05:06:40] <furrywolf> and rocket
[05:06:46] <Valen> furrywolf: the best part is you pretty much need to be supersonic for it to work ;->
[05:07:03] <Valen> actually listening to that thing take off it was pretty darn quiet
[05:07:22] <ssi> at that distance though, it's not much quieter
[05:07:31] * Valen used to live under the flight path of a light aircraft airport, that thing is way quiet lol
[05:08:02] <ssi> it's only 80hp
[05:08:11] <Valen> I think its the tone of it, the noise is "smooth" if you will
[05:08:15] <ssi> a 75hp cub is just as quiet
[05:08:23] <Valen> no bangy noises
[05:09:07] <ssi> https://www.youtube.com/watch?v=3BY4mDAiy6Q
[05:09:11] <Valen> The other reason for having the hybrid system was fault tolerance, you can handle one electric motor failing, the petrol engine failing or the battery pack failing
[05:09:26] <ssi> so what, twin props?
[05:09:39] <Valen> 2 motors one shaft
[05:09:48] <Valen> if you fry a motor you can still spin it as a rule
[05:09:52] <ssi> two electric motors on one shaft, plus the engine is just a generator?
[05:10:06] <Valen> that was my plan yeah
[05:10:17] <Valen> lots more bits to go wrong of course
[05:10:20] <ssi> I think the engineering on that is gonna get away from you in a hurry :)
[05:10:23] <furrywolf> crap efficiency, too.
[05:10:36] <ssi> weight is a real thing!
[05:10:56] <ssi> how much power do you anticipate per motor
[05:11:05] <furrywolf> 1/2 engine. :P
[05:11:07] <Valen> furrywolf: in the dream aeroplane the goal of all that crap was to get off the ground, to altitude and off the coast
[05:11:26] <Valen> ssi: no maths been done, only fantasy so far ;->
[05:11:34] <ssi> and fantasy it's likely to stay :)
[05:11:37] <Valen> it wasn't going to be a small craft by any stretch
[05:11:40] <Valen> most likley ;->
[05:11:58] <ssi> the challenges go up exponentially with weight
[05:11:58] <furrywolf> see, at least my mental designs would result in a functioning aircraft. :P
[05:12:06] <ssi> furrywolf: yeah you're closer to sanity
[05:12:09] <Valen> furrywolf: once off the coast you dive to gain speed then light the ramjet ;->
[05:12:13] <ssi> but still not in the realm of practicality
[05:12:20] <Valen> ssi: mine is *way* more fun though right?
[05:12:30] <ssi> parts of it are
[05:12:35] <ssi> I'm not crazy about the hybrid thing
[05:12:42] <ssi> electric systems have crap energy density
[05:12:42] <Valen> I wasn't wedded to it
[05:12:53] <Valen> it's not going to be a small craft anyway
[05:12:55] -!- Nick001 [Nick001!~Nick001@50.107.152.43] has parted #linuxcnc
[05:13:06] <ssi> now you're carrying battery packs with crap power density, plus fuel for the genny, plus fuel for the ramget
[05:13:13] <ssi> plus FOUR engines
[05:13:32] <ssi> I'd love to have you put some numbers down and start working the math
[05:13:37] <ssi> the math on this stuff is enlightening :)
[05:13:43] <ssi> see what I want to do
[05:13:48] <Valen> or enheavying as the case may be?
[05:13:52] <furrywolf> skip the ramjet and go nuclear thermal... refuel every ten years. :P
[05:13:55] <ssi> is design and build a single seat airplane with a spitfire planform
[05:14:05] <ssi> retractable gear, 180-210hp
[05:14:08] <ssi> and make it go 350mph
[05:14:09] <furrywolf> lol
[05:14:10] <ssi> that's my goal
[05:14:13] <SpeedEvil> Ramjets are _hideously_ fuel inefficient at under mach 2
[05:14:17] <ssi> and it's steeped in reality
[05:14:28] <Valen> certain regulatory issues with that one furrywolf, though locmart are working on it ;-P
[05:14:59] <SpeedEvil> ssi: full sale?
[05:15:01] <Valen> SpeedEvil: yep ;-> lots of nice heat tolerant stainless steel in the construction ;->
[05:15:03] <ssi> yes
[05:15:35] <ssi> I want to build a seat mockup, put my wide ass in it, and esentially design the cockpit around me
[05:15:37] <SpeedEvil> ssi: Well - 1500hp or so is needed
[05:15:39] <ssi> then design the airplane around the cabin
[05:15:48] <ssi> SpeedEvil: how do you figure?
[05:15:55] <ssi> oh I don't mean fullscale as in spitfire sized
[05:16:01] <SpeedEvil> ah
[05:16:04] <ssi> I thought you meant full scale as opposed to RC
[05:16:22] <ssi> I just want to borrow the planform
[05:16:22] <ssi> http://en.wikipedia.org/wiki/Supermarine_Spitfire#mediaviewer/File:Spitfire_mk2a_p7350_arp.jpg
[05:16:27] <furrywolf> ssi: now, for experimental craft, I want to build an external-energy-source rocket.
[05:16:41] <Valen> ssi: any paticular reason?
[05:16:42] <ssi> spitfires are 1500hp because they're HEAVY
[05:16:49] <ssi> 6700lb MTOW
[05:16:58] <ssi> Valen: because it's BEAUTIFUL
[05:17:05] <furrywolf> first stage will be an externally heated jet engine... :P
[05:17:06] <ssi> Valen: because the elliptical wing is the most efficient
[05:17:07] <Valen> that is totally a legit reason ;->
[05:17:10] <ssi> theoretically perfect lift distribution
[05:17:27] <Valen> I like the noise of the merlin too much though ;->
[05:17:34] <Valen> (now *that* would piss off the neighbours)
[05:17:42] <ssi> I can't afford a merlin
[05:17:50] <ssi> I want to go 350mph on a 4cyl lycoming
[05:17:53] <ssi> which I can afford :)
[05:18:15] <ssi> http://en.wikipedia.org/wiki/Sharp_Nemesis
[05:18:18] <ssi> is proof that it's feasible
[05:18:22] <ssi> 292mph on 100hp
[05:18:24] <Valen> this is totally worth the 3 minutes with headphones on btw
https://www.youtube.com/watch?v=c6c3v9iihgw
[05:18:40] <Valen> no music or any crap over them
[05:18:51] <ssi> Valen: we don't get many spits in the US
[05:18:58] <ssi> I've seen two togehter in person, that's it
[05:19:10] <ssi> but I have watched fifty P51 mustangs start, taxi out, and takeoff together
[05:19:19] <ssi> in person
[05:19:20] <Valen> I've only ever seen one i think in person, not flying
[05:19:43] <Valen> I'd love to hear one do a flyover, without some asshat blasting noise over it
[05:20:06] <ssi> https://plus.google.com/photos/109878413921179873667/albums/5636833338900729857?banner=pwa
[05:20:11] * furrywolf likes quiet
[05:20:22] <Valen> I do too, but I still love that sound
[05:20:47] <ssi> there's nothing like it
[05:21:05] <ssi> radials too
[05:21:07] <ssi> https://pbs.twimg.com/media/B9gWEdzIEAAs-BB.jpg:large
[05:21:11] <ssi> I got to fly that last weekend :D
[05:21:57] <Valen> you better paint it in cammo and put some pipes sticking out of the wings ;->
[05:22:04] <ssi> heheh
[05:22:13] <ssi> i probably will have to do a spit scheme if I build the damn thing
[05:22:15] <ssi> would be amazing
[05:22:53] <Valen> how would you go about getting a ramjet aircraft off the ground and up to a decent altitude in a way not likely to cost squillions?
[05:23:25] <ssi> I'd try to build a DIY version of the J58 :)
[05:23:59] <ssi> start with a small low- or no- bypass jet of some kind
[05:24:00] <Valen> hah *way* too complex
[05:24:18] <ssi> and try to come up with the ability to make it scram capable
[05:24:20] <ssi> I dunno
[05:24:20] <ssi> hehe
[05:24:45] <ssi> I don't tend to think beyond mach 1
[05:24:57] <ssi> there's a lot more problems there than just ghetting it off the ground and to altitude :)
[05:25:29] <ssi> I'm pretty good at this stuff for someone who's not an actual AE, but I'm not that good
[05:25:48] * furrywolf is pretty good at rednecking things
[05:26:24] <ssi> rednecking airplanes happens, but you have to be a bit more cautious :)
[05:26:47] <furrywolf> from what I've seen at the local ga field, it happens fairly often. :P
[05:27:03] <SpeedEvil> ssi:
http://www.monfortonpress.com/ oooh
[05:27:19] <ssi> furrywolf:
https://www.youtube.com/watch?v=KkXX2Gu-bfg
[05:27:35] <ssi> SpeedEvil: nice :D
[05:28:27] <SpeedEvil> The spitfire cockpit doesn't look 'roomy' - if you want to simply scale it.
[05:28:44] <furrywolf> yeah, that's fairly redneck.
[05:28:51] <Valen> I was liking that with my setup was the redundancy, lots of things can break without causing you to go splat by necessity ;->
[05:28:58] <ssi> I don't really intend to build a scale spit
[05:29:02] <ssi> just borrow its planform
[05:29:08] <SpeedEvil> ah
[05:29:38] <SpeedEvil> Can always go multi-engine.
[05:29:39] <SpeedEvil> http://www.electravia.fr/CriCri/fwztu_ip01.png
[05:30:38] <ssi> I can't fit my ass in a cricri
[05:31:02] <ssi> the original cricri design used chainsaw engines :D
[05:31:21] <ssi> also the designer won't sell plans to americans anymore because he thinks they're too litigious
[05:31:24] <ssi> he's probably not wrong :P
[05:31:39] <furrywolf> some chainsaws have an impressive power/weight ratio. my 80cc mcculloch was scary...
[05:31:51] <Valen> I was estimating my fantasy plane would probably weigh something in the 5000-8000kg range btw
[05:32:04] <Valen> I was somewhat basing it off the lockheed D-21
[05:32:13] <SpeedEvil> ssi:
https://www.youtube.com/watch?v=7kKRjcE9Vnk - wood powered chainsaw
[05:32:31] <ssi> Valen: lawd
[05:32:41] <Valen> hey if you are gonna do it ;->
[05:32:55] <furrywolf> why stop there? build a sr-71 clone to get your ramjet up to speed
[05:32:58] <ssi> that's so heavy you'd need a type rating to fly it
[05:32:59] <Valen> http://www.nationalmuseum.af.mil/shared/media/photodb/photos/071025-F-1234S-009.jpg
[05:33:08] <ssi> >12,500lb requires a type rating
[05:33:12] <Valen> dang :-<
[05:33:37] <Valen> well that does squeek in the lower end, 5669kg ;->
[05:33:44] <SpeedEvil> There is a bug in the UK air regulations.
[05:33:45] <Valen> D-21 is only 5000 ;->
[05:33:56] <SpeedEvil> You can take a 10kg quadcopter, take off.
[05:33:56] <ssi> yea that's only 11,000lb
[05:34:02] <Valen> and I was thinking shorter range
[05:34:02] <ssi> so you'd sneak in under the type rating limit :P
[05:34:05] <Valen> and lower speed
[05:34:08] <ssi> but that's TEN TIMES what my RV7 weighs
[05:34:16] <SpeedEvil> Now, winch up more engines and props and fuel tanks. And then a seat and a pilot.
[05:34:31] <SpeedEvil> And you're still an unmanned small aircraft that is exempt and under the same rules as RC
[05:34:34] <ssi> so I hope you're planning on 3000hp or more
[05:34:48] <SpeedEvil> And has basically no rules.
[05:34:50] <ssi> SpeedEvil: that's just silly
[05:34:56] <furrywolf> lol @ the wood gas chainsaw
[05:35:11] <SpeedEvil> Silly, but legal. (for a very short period till they change it)
[05:35:16] <furrywolf> the satellite tv dish mast chimney is great.
[05:35:30] <ssi> in the US there are very few regs on ultralights
[05:35:33] <Valen> I imagine you would wind up falling afowl of their general "don't be a dick" regulations ;-P
[05:35:38] <ssi> but ultralights are pretty fucking light
[05:35:49] <ssi> I think it's like 254lb empty, 510lb gross
[05:35:50] <SpeedEvil> Valen: there aren't any - I've read the whole regulations.
[05:35:50] <ssi> something like that
[05:36:07] <Valen> there is nothing there about "dangerous operation" or anything like that?
[05:36:14] <Valen> endangering the public
[05:36:15] <SpeedEvil> Valen: yes, there is.
[05:36:16] <ssi> and being a big guy, I can't imagine flying an airplane that weighs less than I do
[05:36:42] <Valen> ssi: they have ultralight rules here that are similar, they do rather feel yiccky in that sense ;->
[05:36:44] <SpeedEvil> Valen: the fun part is that the 'model aircraft' bits say all of the rest of the regulations don't apply as long as you're a model airraft
[05:36:56] <SpeedEvil> Valen: and the above fits unambiguously into the definition
[05:37:51] <ssi> I kinda want to build tnhis wood gas chainsaw
[05:37:52] <ssi> amazing
[05:37:57] <ssi> you can use it to cut up fuel for itself
[05:37:58] <Valen> so there's nothing saying you can't operate a model aircraft in a way that endangers the public?
[05:38:12] <ssi> need to build a bigger robot that can run around and devour forests simply to power its own destructive needs
[05:38:13] <SpeedEvil> Valen: it's not quite framed that way.
[05:38:31] <SpeedEvil> Valen: It's 'you must not fly it over people or houses (paraphrasing)
[05:38:44] <Valen> pretty sure they would get you even on laws not relating to aircraft
[05:38:53] <Valen> "disturbing public order"
[05:39:08] <ssi> SpeedEvil: in the US, the federal aviation regs are almost exclusively written to regulate things which endanger other people and property
[05:39:13] <ssi> they could care less about whether you kill yourself
[05:39:23] <Valen> CASA here is all over everything :-<
[05:39:38] <SpeedEvil> It doesn't say anythin about a pilot, because you can't lift an adult pilot and keep to the unmanned category.
[05:39:58] <SpeedEvil> But - a self-upgrading craft that winches a pilot up later is now possible
[05:40:20] <ssi> possible perhaps
[05:40:21] <Valen> why not just have them all assemble in the air then have the pilot grab on
[05:40:22] <ssi> but feasible?
[05:40:29] <SpeedEvil> Valen: that works too
[05:41:00] <SpeedEvil> ssi: the other loophole in the regs is if you strap on a parachute, and then grab hold of tethers to 10 or so RC aircraft and drag yourself into the air.
[05:41:10] <furrywolf> ssi: here's your bigger robot:
https://www.youtube.com/watch?v=YzaXMzYFtSM
[05:41:16] <SpeedEvil> Parachutes have the same 'none of the other regulations apply'
[05:41:32] <Valen> and a powered parachute?
[05:41:44] <ssi> or parasailing
[05:41:47] <ssi> all sorts of things like that
[05:41:51] <ssi> again, in the US they mostly don't care
[05:41:54] <SpeedEvil> Powered parachutes are under different regs because they have permentantly attached engines.
[05:41:58] <ssi> so long as you don't endanger other air traffic
[05:42:30] <ssi> furrywolf: that's a good start!
[05:43:43] <Valen> this one is good for spitfire noises
https://www.youtube.com/watch?v=cUkAwQkdynA
[05:43:55] <Valen> you can hear the supercharger ;->
[05:44:22] <furrywolf> ssi: all you need to do is convert it to wood gas and tweak the AI a bit...
[05:44:27] <ssi> yusss
[05:45:51] <ssi> Valen: to answer your question
[05:46:03] <ssi> I think the best way for you to launch your D-21 sized ramjet
[05:46:19] <ssi> is to strap it on your blackbird-sized blackbird that you're gonna build along side it :D
[05:46:24] <Valen> hah
[05:46:31] <Valen> that is historically a very very bad idea
[05:46:34] <ssi> :D
[05:46:47] <Valen> even I'm not insane enough to think supersonic seperations are a good plan ;->
[05:46:49] <furrywolf> ssi:
https://www.youtube.com/watch?v=dfqYCbcQcpY is the wheeled version... watch how quickly it processes a tree.
[05:47:14] <ssi> holy crap
[05:47:33] <SpeedEvil> Supersonic seperations aren't bad as long as Q=~0
[05:47:51] <Valen> what are you defining Q as there?
[05:47:56] <ssi> dynamic pressure
[05:48:10] <ssi> Q=~0 is the definition of space :)
[05:48:21] <Valen> ahh, at the point where "supersonic" gets "air" quotes ;->
[05:48:35] <SpeedEvil> If you're up where yes, there are supersonic shocks, but they have ~1PSI force, it's lots easier
[05:48:36] <ssi> yeah as Q goes to 0, the speed of sound goes to infinity :)
[05:48:44] <SpeedEvil> It doesn't
[05:48:49] <SpeedEvil> It stays at ~mach 1
[05:48:50] <ssi> or is it the other way around
[05:48:55] <furrywolf> ssi: I'm quite sure your forest-destroying robot made out of one of these can harvest fuel much faster than it can burn it. :P
[05:49:11] <ssi> mach 1 isn't a fixed speed
[05:49:16] <ssi> it's variable with altitude
[05:49:21] <Valen> it wobbles as you go up, but I believe it goes back down when you get really high
[05:49:21] <ssi> ie density
[05:49:23] <ssi> ie Q
[05:49:33] <ssi> furrywolf: I'm sure it can!
[05:49:51] <furrywolf> you could use the much-easier-to-find wheeled version, but the walking one is probably required for building an evil robot.

[05:50:42] <ssi> ah well
[05:50:53] <ssi> much like I don't think beyond mach 1, I also don't think much beyond FL600
[05:50:55] <ssi> :)
[05:51:08] * Valen has a degree in space science
[05:51:13] * Valen is itching to use it in anger lol
[05:51:20] <ssi> go play kerbal space program :D
[05:51:21] <furrywolf> lol
[05:51:26] <Valen> I totally do
[05:51:30] <ssi> it's so much fun
[05:51:45] <ssi> http://xkcd.com/1356/
[05:51:46] <Valen> then get shitty at it for being single threaded and having crap connections
[05:52:00] <ssi> I get mad because my stations always make the physics engine go to shit
[05:52:02] <Valen> also that graph is totally accurate
[05:52:06] <ssi> yep!
[05:52:13] * furrywolf has never liked games
[05:52:23] <Valen> KSP isn't a game
[05:52:31] <ssi> ksp is a game the way flight simulator is a game
[05:53:27] <furrywolf> yes
[05:53:59] <ssi> I'm gonna stay home from work tomorrow and hopefully go fly the RV6 a bunch more
[05:54:11] <ssi> I'm trying to get 30 hours in it before they sell it
[05:54:19] <ssi> it'll DRASTICALLY help with my insurance when I get mine finished
[05:54:23] <ssi> I'm at 9 hours thus far
[05:54:41] <Valen> ssi: My other reason for wanting the D-21 is it turns out I get quite airsick ;->
[05:54:45] <ssi> https://pbs.twimg.com/media/B9gMdjZIQAAlRQ0.jpg:large
[05:54:51] <Valen> so less time in the air seems like a good thing ;->
[05:54:54] <ssi> hah
[05:55:11] <ssi> a lot of people who get airsick have fewer issues with it if they're handling the controls
[05:55:17] <ssi> I get airsick in some conditions if I'm not flying
[05:55:19] <Valen> you say that.....

[05:55:50] <Valen> they wobble
[05:55:54] <ssi> yes, by design :D

[05:56:30] <ssi> btw the reason that RV has a pink cowl

[05:56:36] <Valen> that aside, its just freaky how wobbly the ride is
[05:56:38] <ssi> :D
[05:56:49] <Valen> i mean you can feel trees from 500ft
[05:57:00] <ssi> I don't have any significant time in rotorcraft sadly
[05:57:05] <ssi> I would really like to get my rotorwing addon
[05:57:13] <ssi> but they're horribly expensive
[05:57:26] <Valen> also as a fellow husky gentleman you will need to go up a size in heli
[05:57:30] <ssi> my most significant time in rotorcraft was the lifeflight ride I got when I crashed my motorcycle :P
[05:57:34] <ssi> yeah I know
[05:57:40] <ssi> R22 has a seat weight of 235lb I think
[05:57:45] <Valen> the small ones have a max pasenger weight of like 90kgs
[05:57:47] <ssi> and the cost goes up exponenitally with size
[05:57:49] <Valen> something like that
[05:58:15] <ssi> aircraft in general are very unforgiving to the oversize or overweight :(

[05:59:55] <ssi> good motivation at least
[06:00:02] <ssi> yeah I fit fine in an economy seat
[06:00:19] <ssi> my only problem there is I have screwed up knees from teh aforementioned motorcycle wreck, and they don't like to be penned in for long flights
[06:00:43] <Valen> its scary when you see the pictures of the people they make buy 2 seats and think, they don't weigh that much more than me....

[06:01:07] <ssi> I'm relatively normal sized, but heavy :/

[06:07:16] <ssi> I've been seriously considering taking up crystal meth
[06:07:27] <ssi> I hear it's great for weight loss
[06:07:37] <Valen> its weird when you see the commando type though isn't it and you feel about 2ft high
[06:07:39] <ssi> and I've never been particularly attache dto my teeth
[06:07:49] <Valen> file that under plan-B huh?
[06:07:53] <ssi> yep
[06:07:54] <Valen> take a look at the fasting diet
[06:08:20] <Valen> worked super well for me, not so good for the missus
[06:08:24] <ssi> hm
[06:08:40] <Valen> basically 2 days a week you eat ~500 calories of "good" foods
[06:08:52] <Valen> then the rest of the time whatever
[06:09:32] <Valen> does lots of good things for insulin resistance and all sorts of other stuff
[06:09:44] <Valen> you learn the difference between hungry and thirsty
[06:09:49] <ssi> yeah
[06:09:54] <ssi> haha I heard a good quote recently
[06:10:01] <ssi> "If you're not hungry enough to eat broccoli, you're not hungry"
[06:10:19] <Valen> and its not a "starvation" diet or anything silly like that, so you don't have thyroid problems
[06:10:30] <ssi> might actually work well for me
[06:10:34] <ssi> I tend to forget to eat pretty often
[06:10:39] <ssi> friday I had one meal
[06:10:49] <ssi> today I had one and a half thus far
[06:11:09] <Valen> I think thats why it works, not eating for a little is easier than eating "the right amount all the damn time"
[06:11:12] -!- ariscop has quit [Quit: Leaving]
[06:12:14] <ssi> I think I've eaten approx 1500 cal today
[06:12:22] <ssi> and I'm currently hungry
[06:12:22] <Valen> it also is great for losing fat because during the fasting you have to burn it off, you don't have dietary calories to use instead. Then on your regular days you aren't in "starvation mode" from prolonged reduction in calories so you don't pile it back on
[06:12:24] <ssi> but I waited too long to eat
[06:12:25] <ssi> heh
[06:12:35] <Valen> the recipies are good for it too
[06:12:56] <Valen> meaty breakfast of smoked salmon and mushrooms, or fish and onion
[06:13:15] <Valen> then I have a huge bowl of beans, tomato and tuna for dinner
[06:13:28] <Valen> and an assload of coriander
[06:13:45] <Valen> turns out beans are low in calories, who knew?
[06:13:57] <ssi> I could go for that right now
[06:14:12] <Valen> lol same ;->
[06:14:23] <ssi> I'm guessing you mean coriander leaf, not seed?
[06:14:26] <Valen> yeah
[06:14:31] <ssi> cause an assload of coriander seed doesn't sound appetizing
[06:14:42] <ssi> we'd just call it cilantro in leaf form :D
[06:14:44] <ssi> and I loooove it
[06:15:31] <ssi> dammit now I'm hungrier than I was

[08:35:34] <SpeedEvil> there is 8/8 allthread

[08:39:02] <SpeedEvil> I'm quite aware this would not be ideal. Good enough - well...

[08:40:13] <witnit> brilliant,
[08:40:21] <SpeedEvil> I know in principle why it's going to be crap.
[08:40:32] <SpeedEvil> I don't know in terms of actual numbers how crap.
[08:42:24] <witnit> what kind of load is it?
[08:43:12] <archivist_herron> I used a bit for the leadscrew on my hobbing machine but that axis has little need for accuracy when cutting spur gears

[14:59:56] <JT-Shop> how fast depends on the voltage and the driver and how fast you can make step pulses

[15:09:58] <CaptHindsight> JT-Shop: SLA is much faster and higher res
[15:10:23] <CaptHindsight> if you need that
[15:11:01] <JT-Shop> what is SLA?
[15:11:50] <CaptHindsight> well SLA with DLP or LCD, you use a photopolymer with a laser+galvo (slowest) or DLP/LCD projector
[15:12:13] -!- ejb has quit [Quit: ZZZzzz…]
[15:12:24] <JT-Shop> got a link to that?

[15:14:16] <CaptHindsight> https://www.youtube.com/watch?v=eKk2vRysioE this is SLA but using a projector like DLP/LCD prints a layer at a time vs just a point
[15:15:20] <ssi> morn
[15:15:50] <JT-Shop> not DIY I think
[15:16:09] <CaptHindsight> it's easy DIY
[15:16:20] <CaptHindsight> you just have a Z axis for motion
[15:17:47] <CaptHindsight> project the image 1 second, move the Z down below the surface of the resin, and then back up minus the layer thickness, project the next layer, repeat
[15:19:08] <CaptHindsight> the g-code is really simple
[15:19:10] <JT-Shop> got a DIY link?
[15:19:31] <JT-Shop> brb, gotta shovel more snow
[15:24:56] <SpeedEvil> JT-Shop: with g-code?
[15:25:01] <SpeedEvil> And if not - why not
[15:30:15] <JT-Shop> don't ask me I'm still trying to figure out what CaptHindsight is talking about
[15:32:16] <CaptHindsight> JT-Shop: here is one version
http://code.google.com/p/lemoncurry/wiki/main but I'd suggest using the top projection to the surface of the resin vs up through the bottom of a vat

[16:02:25] <CaptHindsight> JT-Shop: there is software that slices STL's and makes a stack of SVG's for the projector
[16:03:43] <JT-Shop> that makes sense to me
[16:04:03] <tjtr33> i see the wiper, and i read about 12um vertical steps. is there some 'nearly solidified' area above the 'really solidified' area that is aided by the wiping?
[16:04:22] * JT-Shop noticed the snow has stopped and neither tractor has the correct implement on it to grade the driveway
[16:04:37] <CaptHindsight> the wiping is for dealing with the surface tension of the resin
[16:05:20] <CaptHindsight> tjtr33: ever fill a glass to just over the rim?
[16:05:23] <tjtr33> ah, the wiping is not at the top of the part, its a skin thing at tank volume surface
[16:05:28] <tjtr33> menscus?
[16:05:53] <CaptHindsight> the wiping breaks the surface tension
[16:06:03] <tjtr33> add a drop of soap :)
[16:06:29] <CaptHindsight> it's a bit more complicated than that
[16:06:35] <tjtr33> very interesting videos, esp #1 from MrSec
[16:07:07] <tjtr33> joke @ soap ^^^
[16:08:20] <CaptHindsight> well surfactants are used in inkjet inks
[16:12:51] <CaptHindsight> if you're using a very high viscosity resin say 1K cps, like warm honey, it takes a while for the vat to settle, the wiper speeds that up
[16:17:17] <tjtr33> ah, i didnt see that part, leveling the mound, likely irregular over surface of part vs empty tank.
[16:17:33] <JT-Shop> how expensive is the projector?
[16:19:34] <tjtr33> JT-Shop, i got mine from a school district upgrading theirs, newish epson for 100$. brand new off shelf can be >1K$, but lotsa people updgrading their smancy home theatres
[16:20:22] <tjtr33> i use it to watch movies on garage door in summer ;) have not done DLP yet
[16:21:07] -!- vapula has quit [Quit: Leaving]
[16:21:32] <JT-Shop> yea 1k would be a bit tough to chew
[16:21:56] <CaptHindsight> I've gotten many on ebay for <$100
[16:22:25] <JT-Shop> so you have built them?
[16:22:42] <CaptHindsight> if you modify the projector to use an $10 LED vs lamp you can get projectors for next to nothing
[16:24:50] <tjtr33> yeah its the bulb that has limited remaining life that gets you on the used units. like buying a car with no odometer
[16:25:21] <CaptHindsight> the lamps are $100-250ea and they are very inefficient
[16:25:39] <CaptHindsight> been using LED for the past few years
[16:25:50] <tjtr33> btw newegg has a few 2500lumes for 300$ new
[16:26:38] <XXCoder1> CaptHindsight: what kind of led lamp
[16:26:40] <CaptHindsight> a 10W LED is <$10 now in the 405nm or 450nm range
[16:26:54] <XXCoder1> always wanted good projector. I use eyeclops for now lol
[16:27:17] <CaptHindsight> I think we pay $35 for the 100W leds
[16:27:24] <tjtr33> cool, an led bulb hack for my epson
http://hackaday.com/2013/03/28/epson-projector-led-mod/
[16:27:31] <XXCoder1> chwap here, just $15
[16:27:45] <XXCoder1> special goverment deal, they pay for half led

[16:30:14] <CaptHindsight> XXCoder1: >390nm work fine in the projectors, >400nm for the ones with UV coatings, 450nm is the Blue used in the LED RGB projectors
[16:30:36] <XXCoder1> interesting
[16:30:50] <XXCoder1> so end result would be fine?
[16:32:22] <CaptHindsight> and it also depends on the resin, I make them for UV as well as up to Blue/Green, well really up to IR
[16:33:14] <XXCoder1> cool
[16:34:02] <CaptHindsight> JT-Shop: an HD (1920 x 1080) projector gets you 0.004" XY res at 7.5" x 4"
[16:35:03] <CaptHindsight> 0.002" XY 3.25" x 2"
[16:35:38] <XXCoder1> eyeclops is fun projector lol
[16:35:41] <XXCoder1> tiny but works
[16:36:07] <XXCoder1> it was ugly hack to get my ancient captioning machine to work with it
[16:36:20] <JT-Shop> nice
[16:36:32] <XXCoder1> I use dvd machine - > vcr -> caption -> vcr -> eyeclops
[16:36:42] <XXCoder1> yes thats two vcr machines
[16:37:02] <XXCoder1> im using em as cheapass conversion of format (rca to coaxial then back(
[16:40:47] <CaptHindsight> cooling a 20W+ led is challenging for many
[16:41:16] <XXCoder1> bigass copper heatsink with stirling fan on it
[16:41:23] <CaptHindsight> many CPU heatsink and fans are good enough for 100W leds
[16:41:52] <CaptHindsight> just hard to find the space inside a projector for them
[16:42:02] <XXCoder1> http://media.treehugger.com/assets/images/2011/10/stirling.jpg
[16:42:08] <XXCoder1> too bad its just concept
[16:42:25] <XXCoder1> one awesome thing is that it means led wont die in sudden blackout
[16:42:30] <CaptHindsight> that would be ok for 10W or so
[16:45:28] <_methods> peltier coolers won't work?
[16:46:27] <CaptHindsight> peltier (like a heatsink or heatpipe) just move heat from one place to another
[16:47:05] <CaptHindsight> you could use a peltier to move the heat from the back of the LED to a heat spreader and then off into the ambient air
[16:47:46] <_methods> i have no idea i just thought maybe for space constraint situation maybe a peltier
[16:48:20] <CaptHindsight> or a water cooling system to move the heat outside the projector

[16:52:16] <CaptHindsight> just like a cpu heatsink+fan combo
[16:53:01] <XXCoder1> dang
[16:53:10] <XXCoder1> how many lumens would that be
[16:53:40] <CaptHindsight> it's in a very narrow band
[16:53:57] <CaptHindsight> so you don't use lumens like you might for white light
[16:54:36] <XXCoder1> but how bright would end result be?
[16:54:43] <CaptHindsight> 4000mW/cm2 (385-400nm)
[16:55:02] <CaptHindsight> 4 watts /cm^2
[16:55:32] <XXCoder1> I guess thats like using 4w light a cm away
[16:55:40] <XXCoder1> hitting 1cmx1cm area
[16:55:54] <CaptHindsight> if the 4w lamp was 100% efficient
[16:56:07] <XXCoder1> yeah I used that assumation too
[16:59:51] <CaptHindsight> if you use 1 lumen/cm2 = 1.464129 mW/cm2 then 2700 lumen/cm2
[17:00:21] <XXCoder1> jeez thats powerful
[17:00:57] <CaptHindsight> yes a 10W 405 or 450nm led will leave you seeing spots for quite some time at 3ft
[17:01:05] <XXCoder1> im sure projector would cause some losses, it projects rgb after all
[17:01:32] <CaptHindsight> depends on the projector and optics
[17:01:45] <XXCoder1> CaptHindsight: guess what lumens eyeclops project lol
[17:02:08] <CaptHindsight> but a 2w led at 405nm can get you 1 sec cure times at 100um layers

[19:40:07] <CaptHindsight> Z-axis vs 3 axis
[19:40:20] <CaptHindsight> used projector vs extruder
[19:40:33] <CaptHindsight> materials are about the same price
[19:41:47] <tjtr33> any thoughts on sla for lost-'wax'? (mold cores) any preferable material?
[19:41:56] <CaptHindsight> like everything diy cnc, it all depends on your scrounging skills

[19:42:58] <furrywolf> wow, I just measured 229A into my inverter. that be a new record.
[19:43:04] <CaptHindsight> tjtr33: you use resins with very low to no inorganic materials so no to low ash when burned out

https://stlouis.craigslist.org/search/sss?sort=rel&query=video+projector
[19:44:17] <tjtr33> thx CaptHindsight
[19:46:37] <zeeshan> anyone know how to place a stock 45 degree
[19:46:43] <zeeshan> from the x axis
[19:46:44] <zeeshan> in mastercam
[19:47:10] <JT-Shop> tjtr33, which one would be good for SLA?
[19:47:32] <Tom_itx> zeeshan what about smartcam? group all, then 2d rotate
[19:47:39] <zeeshan> no smart cam
[19:47:52] <Tom_itx> i'm sure it's similar
[19:47:56] <CaptHindsight> you just want to avoid any DLP projector with the "white dots" problem
[19:48:15] <CaptHindsight> the white dots are stuck micro-mirrors

[19:48:41] <Tom_itx> _methods so it will fit on his mill :)
[19:48:48] <_methods> if you need to do something funky with the stock make an stl
[19:48:50] <CaptHindsight> they will place unwanted spots/lines into your prints
[19:49:01] <_methods> of your custom stock and its orientation
[19:49:33] <_methods> then import the stl into your stock from file

[19:50:11] <_methods> if you're just trying to orient the part that is another story
[19:50:38] <tjtr33> JT-Shop, I'd say any of those epsons, but asking which one is like asking 'which mobo is good for linuxcnc' :)
[19:50:56] <tjtr33> really really moot
[19:51:11] <CaptHindsight> Epsons are all LCD so the only supplier for resin is me
[19:51:41] <tjtr33> oh! lucky im close, but whats the alternative?
[19:53:00] <furrywolf> why is resin so annoyingly expensive?
[19:53:04] <CaptHindsight> LCD's use color filters on the LCD's, Blue is at 450-460nm, and the other resins drop off >420nm
[19:53:12] <zeeshan> methods
[19:53:14] <zeeshan> you were right
[19:53:15] <zeeshan> that worked
[19:53:19] <CaptHindsight> furrywolf: it's the same or lower than PLA
[19:53:39] <JT-Shop> yea, my luck not having a PHD in SLA I'd get the wrong thing and just be tossing money in the fire
[19:53:45] <furrywolf> I mean compared to buying products made of plastic. the resin costs many times more than what a commercial finished product would cost.

[19:55:24] <jdh> isnt that a lot of volume to melt and displace?
[19:55:26] <CaptHindsight> up until now it's been the SLA printer makers charging $200+/kg
[19:55:35] <JT-Shop> jdh, you burn it out
[19:55:42] <CaptHindsight> the PLA or resin burns out
[19:55:54] <CaptHindsight> as gas
[19:56:26] <witnit_> so resin = treesap? haha

[19:56:55] <witnit_> im not educated in such things
[19:56:57] <_methods> you can save your stl's from ops also

[20:05:55] <furrywolf> snow?! we have the opposite here... it's so bloody hot I turned the a/c on in my van.
[20:06:21] <zeeshan> ah i see methods

[20:06:23] <zeeshan> lemmne try that :P
[20:06:28] <tjtr33> JT-Shop, good resource thx
[20:06:31] <CaptHindsight> furrywolf: and others are $20/lb
[20:06:37] <PetefromTn_> zeeshan you can just do Xform and then rotate no?
[20:06:51] <_methods> there's no need to really

[20:07:00] <_methods> hahah
[20:07:06] * furrywolf thinks it's more "we're selling to a specialty market so we can jack the price up as much as we want".
[20:07:07] <CaptHindsight> scorching 16F right now
[20:07:09] <_methods> he can just make a plane on that angle
[20:07:18] <_methods> a work coordinate system
[20:07:26] <PetefromTn_> I am not exactly sure what he is trying to do..
[20:07:40] <_methods> he wants the stock to work so he can see a correct simulation
[20:07:49] <_methods> and the work is on an angle across his table
[20:07:56] <_methods> but he's bringing the model in already angled
[20:08:05] <_methods> so mastercam is making a giant sq around it for stock
[20:08:20] <PetefromTn_> if the model is already angled why does he need to rotate anything?
[20:08:38] <_methods> he has it angled the way he wants but the stock feature is making a giant stock around it
[20:08:53] <_methods> his only other option for stock is to import a stock stl
[20:09:02] <_methods> but it's a pain in the ass to align
[20:09:06] <CaptHindsight> it's making a square around the outside of his part
[20:09:10] <_methods> yes
[20:09:17] <_methods> to the extents of the part
[20:09:20] <_methods> on a 45
[20:09:24] <_methods> or whatever angle that is

[21:20:50] <furrywolf> my first test, when presented with that problem, would be to apply vacuum directly to the egr valve and see if the engine stalls.

http://fortwayne.craigslist.org/tls/4894057246.html
[21:22:24] <furrywolf> my personal experience is 90% of egr problems are clogged lines.
[21:22:33] <XXCoder1> I did find bit loose connector (in video you can see topmost connector)
[21:22:36] <furrywolf> and remaining 10% being actual failures.
[21:22:47] <XXCoder1> how do I test clogged lines?
[21:23:01] <XXCoder1> most of thin vacuum lines is new
[21:23:05] <furrywolf> first, you apply vacuum to the valve at idle and see if the engine stalls. :)
[21:23:13] <XXCoder1> (old ones literally shattered, took me while)
[21:24:01] <XXCoder1> I guess need clean hose so I can just suck it
[21:24:17] <XXCoder1> blowjob to be sure :P Im experenced with it I guess, what woith nes and all LOL
[21:24:33] <furrywolf> there's a tube that runs from the egr valve down to the exhaust. it's usually what clogs. yours apparantly has additional complication of an orifice tube that creates a restriction that creates a pressure differential that is measured to determine flow.

[21:25:35] <witnit> zeeshan,
http://s65.photobucket.com/user/macona/media/DSC03137.jpg.html
[21:26:01] <furrywolf> either use a handheld vacuum pump, or run a line from a manifold vac source straight to the valve. disconnect the valve, have a long line with enough room to move around. plug with something, start engine. remove plug, stick finger over end of tube. then stick tube on valve. the engine should stall or substantially bog down.

[21:31:13] <XXCoder1> im not sure where to find other end
[21:31:15] <furrywolf> the vacuum test is a quick way to determine if the problem is actually related to exhaust flow, or is a problem with the control system or sensors.

[21:32:24] <furrywolf> if flow is good, opening the valve full open (by applying unregulated vacuum to it) at idle will usually instantly kill the engine, as exhaust doesn't burn.
[21:32:40] <furrywolf> if the engine dies, you probably have ok flow. if the engine keeps on running, your lines are clogged.
[21:33:21] <furrywolf> if the line is clogged, the usual fix is to run a coathanger down it. but, yours has an orifice tube, which is a complication.
[21:34:43] <furrywolf> unfortunately, my non-factory manual gives very few details.
[21:35:39] <furrywolf> ah, found more details... for some reason a basic system diagram was hidden under pinpoint tests. :P

[21:49:09] <andypugh> Looks like an EGR with no position loop. I gues it runs closed-loop on MAF alone.
[21:49:51] <furrywolf> andypugh: it uses an orifice tube and measures the pressure drop across it with a differential pressure transducer to determine actual egr flow, rather than caring about the valve position
[21:50:21] <furrywolf> or, as I see it, "more, smaller bits to get coked up"

[21:52:58] <witnit> get the wifes vacuum and just size your way down to something to work with if you need to keep testing
[21:53:01] <witnit> just an idea :P
[21:53:04] <furrywolf> ok, so either your egr valve is bad, or the line from the valve down to the exhaust is plugged. on your valve, can you visibly see the valve shaft, or feel the diaphragm? (some valves you can, some are enclosed)
[21:53:23] <XXCoder1> witnit: sure so first step is to be married?
[21:53:45] <witnit> it doesnt have to be your wifes vacuum
[21:53:49] <XXCoder1> lol
[21:54:11] <XXCoder1> I dont want to disconnect and buy yet another gasket
[21:54:21] <XXCoder1> I just gonna figure how to find other end
[21:54:30] <furrywolf> picture I found of what should be yours shows it's enclosed
[21:54:43] <furrywolf> disconnect the egr tube from the valve, leaving the valve on the intake.
[21:54:59] <XXCoder1> yeah
[21:55:13] <furrywolf> http://fw.bushytails.net/1998%20Ford%20Contour%202.5l%20EGR%202.pdf is the slightly-helpful section on the egr tube
[21:55:22] <andypugh> Have you sucked on the tube? You can at least feel a leaky diphragm that way,
[21:55:35] <XXCoder1> andypugh: it seals very well
[21:56:23] <furrywolf> andypugh: I'm disinclined to think it's the valve, as he tried the "replace parts and see if it helps" approach and it didn't. :)
[21:56:37] <witnit> if we all were in the same town, we could start a do all machine shop out of a scrapyard and turn profit all day
[21:56:59] <witnit> so many people knowing so much of each field of the industry
[21:57:03] <XXCoder1> I bought egr, then forgot about it as car couldnt run (many water stuff broken)
[21:57:04] <furrywolf> since you had the valve off recently, the tube is probably not TOO badly rusted in place. it might still be tough. do NOT round it. if you can't get it out, get a proper line wrench.
[21:57:13] <XXCoder1> then I used van for a while, fixing part a time
[21:57:18] <XXCoder1> by then return had expired
[21:57:45] <XXCoder1> yeah I made sure to spray wd40 so top part in least should be easoer
[21:57:47] <furrywolf> egr tubes without fail rust in place
[21:58:12] <XXCoder1> and yeah it was tough first time lol I soaked in wd40 few times and waited in order to slowly loosen

[21:58:55] -!- FinboySlick has quit [Quit: Leaving.]
[21:58:57] <furrywolf> next step is to remove tube from valve. leave other end attached, just pull tube enough out of the valve that you can rest it on the side of the valve instead of in the port. unplug the vacuum hose to the valve. start the car. does exhaust come out of the tube?
[21:58:57] <XXCoder1> need bit more context
[21:59:06] <furrywolf> it's the top of your catalytic converter
[21:59:18] <XXCoder1> ok be back
[21:59:21] <furrywolf> or manifold
[21:59:24] <furrywolf> might just be manifold. :P
[21:59:40] <furrywolf> whether or not exhaust comes out of the tube, repeat the vacuum-straight-to-valve test.
[21:59:51] <andypugh> Most folk are happy when their EGR valve stops working. Fuel economy tends to improve, though you won’t pass an emissions test
[22:00:43] <furrywolf> with the tube disconnected, if it still doesn't stall when vacuum is applied, the problem is the valve or the intake, or your vacuum source isn't. if it does stall with the tube removed, and there's no exhaust coming out of the tube, you've pretty definitively identified a clogged tube.
[22:01:18] <witnit> "pretty definitively"
[22:01:22] <witnit> hehe

[22:44:38] <furrywolf> you might have to get to the other end, then. normally they can be bent a fair bit without damage, but I've never worked on that car...
[22:44:57] <XXCoder1> its solid metal hose
[22:45:01] <furrywolf> yes
[22:45:15] <furrywolf> I'd hope so, since it has hot exhaust flowing through it. :P
[22:45:17] <XXCoder1> I guess I gonna find other end then
[22:45:21] <XXCoder1> lol ok
[22:45:30] <Nick001-shop> <pcw_home> you around?
[22:45:38] <furrywolf> looks like either your manifold, cat, or cat/manifold combo...
[22:45:45] <XXCoder1> its really really nasty to remove hose from egr
[22:45:55] <pcw_home> Yeah for a bit
[22:45:58] <XXCoder1> good thing I got this special short tool from dad or grandfather

[23:37:10] -!- XXCoder2 has quit [Ping timeout: 255 seconds]
[23:37:21] <andypugh> Very high qulaity lathes have a separate set of bearings just for the pulley so that belt noise doesn’t affect the finish.
[23:39:00] <andypugh> There is a picture of such an arrangement on the Crowell lathe here:
http://www.lathes.co.uk/cromwell/index.html
[23:39:03] <Crom_> Wow my phone has been running askchat since saturday
[23:39:19] <andypugh> (See the sectional drawing)
[23:41:41] <Crom_> Time to try making the flexable boning clamp press pieces out of 1/2 aluminum
[23:42:07] <XXCoder1> furrywolf: im kinda stick
[23:42:09] <XXCoder1> stuck
[23:42:28] <XXCoder1> cant access the other end without anything to lift car
[23:43:19] <Crom_> Xxcoder bigger hammer always works for me
[23:43:41] <witnit_> andypugh, Very similar design, see pulley in center is captured by flange on each side
[23:43:43] <witnit_> http://www.lathes.co.uk/cataract/img6.gif
[23:43:49] <Crom_> Cant block the jack up end on cribbibg?
[23:44:05] <witnit_> spindle slides into this pulley/sleeve
[23:44:54] <witnit_> once the spindle is out, the sleeve/pulley drops 1/8th inch and is still captured
[23:45:18] <XXCoder1> Crom_: lift car with hammer? lol

[23:49:33] <Crom_> Dont use cinder blocks on thier sides and put a board underneath and a couple on top
[23:52:08] <andypugh> You probably need to extract the bearings too.
