[00:00:10] <MacGalempsy> is it an iso?
[00:00:10] <Contract_Pilot> it is LinucCNC with a nice user innerface
[00:00:25] <MacGalempsy> i dont care about the interface, the hard part is the programming
[00:00:26] <Contract_Pilot> I made an ISO of it.

[00:45:41] <sector_0> I'm building a corexy machine for light milling
[00:45:47] <sector_0> my machine looks something like this
[00:45:51] <sector_0> http://designwiththemajority.com/sites/default/files/inline-images/gantryFull.jpg
[00:46:01] <sector_0> but the 2 y axis carriage unfortunately has a bit of slop so one moves a slight distance without the other
[00:46:07] <sector_0> I've decided to correct this problem by using a cross bar
[00:46:20] <sector_0> I'm planning on create 2 cross bars, one at that connects to the back of each carriage and one that connects at the front of each carriage
[00:46:39] <sector_0> would epoxy be good enough to hold this in place?
[00:46:44] <sector_0> the bonding surface is approximately 1 square inch
[00:46:48] <sector_0> ...one either side
[00:46:56] <sector_0> s/one/on
[00:48:47] <Praesmeodymium> I suspect the issue of getting an answer to this one is both people dont haveenough info on the forces nvolved and the epoxy in question, and even if all that info is in hand I think the answer is going to end up... let us know how it goes
[00:49:22] <sector_0> pfft
[00:49:35] <sector_0> my thoughts exactly
[00:49:59] <sector_0> I was hoping that I won't have to ruin my carriages with epoxy and then it doesn't work
[00:50:09] <Praesmeodymium> shapelock?
[00:51:19] <sector_0> Praesmeodymium, wish I had access to that
[00:52:09] <malcom2073> Yeah, it depends entirely on how much force, but I'd bolt it rather than using epoxy, since those cross bars are going to take the majority of the force when cutting near the edge
[00:52:10] <sector_0> I'll have to order it, which would take about the same time it takes for me to try out the epoxy and have the part machined again with a build in cross bar
[00:52:17] <Praesmeodymium> its pcl it comes under a couple names
[00:54:53] <sector_0> I'll have to check
[00:55:31] <sector_0> malcom2073, I would do that but the carriage is actually pretty small and I'll need at least 2 bolts to stop any kind of slop
[00:55:50] <malcom2073> sector_0: Lightweight is the bitter enemy of milling :P
[00:55:52] <sector_0> I'll have to check for the pcl
[00:56:21] <sector_0> malcom2073, well it's just for light milling, of soft plastic
[00:56:32] <sector_0> more engraving than anything else
[00:56:44] <sector_0> and 3d printing
[00:57:07] <malcom2073> Yeah you'd be ok with with engraving as long as you don't need super small detail
[00:57:29] <sector_0> malcom2073, what you mean?
[00:57:35] <sector_0> in terms of the slop I have?
[00:57:45] <malcom2073> sector_0: Not slop, flexability
[00:58:00] <sector_0> oh
[00:58:30] <malcom2073> Smooth rod is really flimsy, put a dial indicator on your axis, then push on it with a pound or two of force, see how much it moves
[00:58:52] <sector_0> oh ok
[00:59:04] <sector_0> will have to do that once I have the system setup
[01:00:17] <Praesmeodymium> reprap stuff is really not built with the rigidity of milling in mind. the average goal for reprap is cheap as fuck, if it prints ok then great if not I will print better parts for it till I get better prints lol
[01:00:56] <sector_0> at this point, just the thought of adding a cross bar seems hacked together, so I'm just gonna do something temporary until I can get the part machine with a built-in cross bar
[01:01:12] <malcom2073> Right, but even then, a cross bar will only help minimally
[01:01:46] <sector_0> malcom2073, really?
[01:01:47] <malcom2073> Even for engraving, unsupported smooth rod will likely not give you the results you want, but it'll be a good learning experience, and you'll still have a good printer at the end of it

[01:02:54] <sector_0> malcom2073, just so we're on the same page, my current concern is actually the slop between the 2 y axis carriages
[01:03:23] <malcom2073> Right, and a cross bar properly secured to the end carraiges will solve that particular problem
[01:03:55] <sector_0> malcom2073, but you're referring to the flex in the z axis?
[01:04:04] <malcom2073> No, the flex in both the X and Y
[01:04:16] <sector_0> ohhh
[01:05:03] <sector_0> yeah and my rods are 8mm smooth rods
[01:05:06] <sector_0> ...fuck
[01:05:08] <malcom2073> Heh wowza
[01:05:14] <malcom2073> yeah that's flimsy, I have a set of 8's on my 3d printer
[01:05:45] <malcom2073> Anything you do to strengthen it will make it better as a 3d printer as well, so you're not wasting your time
[01:06:05] <sector_0> well at least I have that going for me
[01:06:22] <sector_0> will have to rethink my CNC design
[01:06:40] <sector_0> what about does slide rails by THK?
[01:06:55] <sector_0> are they superior in any way to smooth rods?

[01:59:12] <Contract_Pilot> Love to Barter!
[02:01:53] <Wolf_> love the random ar upper in the mid of cnc/tooling
[02:02:48] <Contract_Pilot> hahahaha.
[02:03:01] <malcom2073> Ooohhh I saw you on facebook Contract_Pilot
[02:03:03] <t12> i just got a 4jaw
[02:03:07] <t12> i wonder how this will work out
[02:03:09] <Contract_Pilot> Yep.
[02:03:11] amnesic is now known as amnesic_away
[02:03:14] <malcom2073> I thought you were SELLING the mesa boards :-P Was about to ask how much then I realized you wanted to buy :P
[02:03:27] <Wolf_> I need a bigger lathe so I can put my AR on a diet
[02:04:03] <malcom2073> Wolf_: How big of a spindle hole do you need for that?
[02:04:17] <Wolf_> non, between centers
[02:04:51] <malcom2073> Ohhh, how big?
[02:05:07] <Wolf_> iirc the barrel is 1.25” under the hand guard, little over 16”
[02:05:20] <malcom2073> Buy my southbend :P
[02:05:26] <Wolf_> lol
[02:05:45] <Wolf_> if it had a gearbox for threading I would...
[02:05:48] <Wolf_> :P
[02:06:08] <malcom2073> Heh, it has a full changegear set

[02:06:25] <Tom_itx> what's the low thread on it?
[02:06:35] <Tom_itx> my buds will do 3 tpi
[02:06:43] <Tom_itx> most don't go that low
[02:06:58] <malcom2073> Unknown, whatever the 12 gear set for southbends gives ya :P
[02:07:19] <Wolf_> I know my 7x10 won’t do 5tpi, I think I busted a gear trying it

[02:15:31] <Praesmeodymium> I would never ride with said pilot again because in my non understanding world he obviuosly did not inspect the aircraft carefully before take off

[02:20:06] <Contract_Pilot> Seen that one
[02:20:21] <Contract_Pilot> Bad preflight
[02:20:24] <jdh> I don't understand the attraction to 80%, but... how much for one?
[02:20:48] <Contract_Pilot> The attraction is they do not exist!
[02:21:00] <jdh> nothing has to exist
[02:21:27] <Contract_Pilot> Expecially in states where a BG check is required
[02:21:34] <jdh> oh.
[02:22:04] <jdh> I can buy anything (normal) I want from any random stranger, it effectively doesn't exist at that point.
[02:22:06] <Contract_Pilot> No gov does not need to know how many firearms i have hahaha
[02:22:17] <Contract_Pilot> Right.
[02:22:26] <malcom2073> jdh: They're about $70 iirc, I bought a couple like a year or two ago
[02:22:35] <Contract_Pilot> 60.00
[02:22:40] <jdh> or a complete psa blem for $35
[02:22:55] <Contract_Pilot> + Ship + FFL
[02:23:17] <malcom2073> Ah I misunderstood what he was asking, sorry heh
[02:24:07] <Contract_Pilot> I am in to them for what i am in to them for they sell good here since we passed a BG Check law.
[02:24:20] <Contract_Pilot> + People like to make things
[02:24:50] <Contract_Pilot> 7075-T6 Broached Mag Well.
[02:25:21] <Contract_Pilot> But right now they are trading stock.
[02:25:23] <jdh> so you sell to people who can't pass a bg check?
[02:25:34] <Contract_Pilot> It is just a hunk of metal.
[02:25:46] <t12> yeah the main attraction is no-list
[02:25:56] <t12> though i'm sure you end up on some other list really
[02:26:16] <malcom2073> Most people who buy stuff aren't the people who can't pass a BG check, they're the people who don't *want* to have to
[02:26:22] <t12> stolen/black market is likely the most practical no-list way
[02:26:35] <malcom2073> The kind of people who can't pass a BG check typically don't buy legit anyway
[02:26:55] <Contract_Pilot> I can pass a BG Check no problem prefer not to do one so i build...
[02:27:06] <t12> my grandfather was an early anti-gov prepper
[02:27:16] <t12> while simultaniously being a .mil contract negotiator
[02:27:38] <t12> he was convinced the gov was going to do suppression and disarm of population in response to the 60s
[02:27:45] <malcom2073> Heh
[02:27:53] <Contract_Pilot> Stolen markey can = the clink if you get caught with it! if you build it no possesson of stolen firearm
[02:27:57] <t12> so he stockpiled arms
[02:27:59] <malcom2073> That reminds me, isn't the world supposed to end again soon?
[02:28:05] <t12> the world is over!
[02:28:33] <t12> dont get caught with it!
[02:30:36] <jdh> do they anodize them?
[02:32:04] <Tom_itx> malcom2073, it ended already
[02:32:14] <malcom2073> I missed the blood moon?
[02:32:35] <Tom_itx> this isn't reality

[07:34:49] <trentster> They have been set up in stepconf as home + limit x,y,z
[07:35:02] <trentster> now how the heck do I get the machine to auto home for them?
[07:35:30] <Wolf_> its in the manual
[07:35:48] <Wolf_> you need to set the homing speed and sequence
[07:36:10] <trentster> Wolf_: Thanks - so is this something that can/is not done via stepconf?
[07:36:26] <trentster> looking for it in the manual now
[07:36:38] <Wolf_> its under homing :P
[07:36:41] <Wolf_> I think
[07:37:16] <trentster> heh - I am one of those painful people who dig into config files first then read manuals second :P
[07:37:32] <trentster> guess RTFM is very valid for me here.
[07:38:22] <Wolf_> I think got it to set up with stepconf also
[07:38:41] <Wolf_> but I forget, I’ve manually tweaked most of my settings now
[07:39:50] <trentster> I am almost there - only painful thing I need to fix is for some reason if I switch off computer while control box with breakoutboard is still on the spindle fires up
[07:40:07] <trentster> which is a tad dangerous :P
[07:42:56] <Wolf_> yeah, I notice my relays do the same
[07:43:27] <Wolf_> I haven’t hooked them up yet for that reason lol don’t need the spindle turning on + misting running
[07:43:33] <trentster> I am not using a router or relays just a spindle and spindle controller with its own psu
[07:44:00] <trentster> I havent thrown relays into the mix yet
[07:44:12] <Wolf_> works the same way, its pulling the pin low w/out the software running
[07:45:21] <Contract_Pilot> torrent hash wonderful always learning
[07:45:57] <trentster> Wolf_: yup exactly - any ideas how to fix?
[07:46:23] <Wolf_> Contract_Pilot: no idea on the holders, I know I saw someone reviewing one on youtube
[07:46:29] <Wolf_> trentster: no idea
[07:47:34] <Wolf_> hmm, I might just add a “arming” button to my panel for first turn on
[07:47:42] <trentster> Wolf would you mind posting a sample config file where homing has been setup - will probably be a zillion times easier to understand what to do - the manual does not even say which files need to be edited, I assume its mymillname.hal
[07:48:16] <trentster> or is it ini?
[07:48:28] <Wolf_> I think its ini...
[07:48:35] <Wolf_> brb let me go look
[07:48:41] <trentster> thanks man!
[07:49:12] <Wolf_Mill> hmm
[07:51:07] <Wolf_Mill> http://pastebin.com/0EgshLkn 0 is my X axis and has switch setup, rest are commented out right now
[07:51:40] <trentster> ok thanks - looking

[08:18:18] <trentster> Wolf_: is there any particular reason your Search velocity settings are so slow?
[08:18:38] <Wolf_> haven’t really tuned it yet
[08:18:46] <Wolf_> and my machine is sloooow
[08:19:17] <Wolf_> have some binding issues so I can’t move too quick
[08:19:18] <trentster> aaah ok - I work in metric and converted your inch speeds and noticed its really slow
[08:20:10] <renesis> slow like 10 ipm, slow like 0.1 ipm, i am curious what is slow
[08:20:22] <trentster> you are searching at like 1.27mm a minute
[08:20:38] <renesis> thats pretty slow
[08:20:44] <trentster> renesis his file is here http://pastebin.com/0EgshLkn
[08:20:54] <trentster> 1. HOME_SEARCH_VEL = -0.050000
[08:20:54] <trentster> 2. HOME_LATCH_VEL = 0.015625
[08:21:11] <trentster> I mean 1.27mm a second
[08:21:23] <trentster> which is still very very slow
[08:22:01] <Wolf_> I only have one limit switch hooked up, plus I park the table at home :P
[08:22:10] <renesis> yeah but thats not end of the world slow for some stuff
[08:22:26] <trentster> Wolf_: no worries - I was just wondering if I was misinterpreting the speeds somehow
[08:22:29] <renesis> like, you would notice it moving at least
[08:22:36] <Wolf_> lol
[08:22:37] <renesis> kinda
[08:23:02] <trentster> renesis what speeds are you using for homing?
[08:23:29] <renesis> i dont home automatically
[08:23:54] <trentster> ok off to the garage to try it out (break something)
[08:23:55] <renesis> i jog at 45 ipm, itll go up to 60 ipm and be reliable 95% of the time
[08:24:25] <renesis> is not fast
[08:24:42] <trentster> I jog at around 75 ipm
[08:25:07] <renesis> and is like, 15x faster than your thing

[08:46:11] <trentster> Wolf_: very odd I have added values to all 3 axis and the UI now shows a home all button - yet when I click it nothing moves - any ideas?
[08:47:18] <Wolf_> you added sequence numbers right? 0,1,2
[08:48:13] <trentster> I added 1,2,3
[08:48:18] <trentster> maybe thats the issue
[08:48:27] <trentster> let me start with zero
[08:54:35] <Wolf_> oh right, I didn’t copy Z, you want Z = 0, then home x/y (1,2)
[09:02:26] <trentster> Wolf_: ok all working great now :)
[09:02:32] <Wolf_> :)
[09:02:39] <trentster> these proximity switches are nice and accurate

[09:04:21] -!- anomynous_ has quit [Ping timeout: 244 seconds]
[09:06:00] <trentster> I also need to figure out what the best setup for a single switch on each axis should be - I guess use each one as limits and homing plus rely on soft limits as well
[09:06:26] <trentster> Is the norm to home towards negative direction?
[09:06:44] <Wolf_> dunno
[09:07:29] <Wolf_> I do know you want the Z up out of the way when homing
[09:10:32] <trentster> yup makes sense

[09:36:58] <Wolf_> helical ramping
[09:37:13] <fenn> well whatever the equivalent is called in helix notation
[09:37:24] <Wolf_> this is getting milled on the x1, I can’t do large anything

[10:03:37] <XXCoder> open scam is now camotics
[10:03:45] <XXCoder> aw as I always loved that funny name
[10:03:53] <XXCoder> openscam
[10:04:45] <ganzuul> Blender 3D is a far more capable CAD than most FOSS CAD...
[10:05:08] <XXCoder> blender is way too hard for me. I have tried bunch of times. no luck
[10:05:19] <fenn> blender used to not be very good for cad stuff, that may have changed in the years since though
[10:06:02] <Praesmeodymium> I am willing to suggest autodesk fusion as a free cad software free to students and makers, I am on year 2 of my free use, its a wee bit cloud based but works offline
[10:06:26] <fenn> if you're going to bang your head against a weird interface, brl-cad is worth learning especially now that it has nurbs support and can import/export STEP files
[10:06:53] <fenn> Praesmeodymium: is that like being a wee bit pregnant?
[10:07:31] <Praesmeodymium> naw its just stores and does file imports through the vcloud I totally worked offline with it for weeks
[10:07:43] <fenn> are you talking about "inventor fusion"?
[10:07:50] <XXCoder> openscad isnt bad
[10:07:50] <Praesmeodymium> fusion 360
[10:07:56] <XXCoder> programming based though
[10:08:30] <Praesmeodymium> opanscad is tough, it for coders who can describe the world through geometry
[10:09:06] <Praesmeodymium> the parametricness of it makes it super useful when done well
[10:09:07] <XXCoder> solvespace is awesome but WAAAY not enough developers.
[10:09:34] <XXCoder> its forum SUCKS hard
[10:09:35] <fenn> openscad is really hard to use even if you are a coder
[10:09:42] <ganzuul> XXCoder: If you immediately try to learn Blender as a CAD program, you're likely to encounter big problems. I learned it as a graphical design tool, so I'm familiar with most of the important features.
[10:09:42] <fenn> been meaning to try out solvespace
[10:09:57] <XXCoder> fenn: its constrant based

[10:18:17] <XXCoder> yea never worked with ldd
[10:18:44] <XXCoder> always preferred mlcad even with not having any physical stuff
[10:18:53] <XXCoder> (you can put part inside another for one)
[10:20:49] <fenn> in ldd you could do technic gear trains and linkages and then "animate" them by rotating one of the gears, and all the other gears and stuff would move along with it
[10:20:56] <XXCoder> fenn: if you used mlcad you could then use my old program ldrdat2dxf to make it into dxf model
[10:21:00] <XXCoder> then its cnc time babyu

[12:19:07] <ganzuul> Got some second hand grinding wheels for 6 euro a piece.
[12:19:12] <ganzuul> White, pink and green.
[12:19:25] <ganzuul> Passed ring test, 200mm.
[12:19:34] <ganzuul> But what do I use these colors for?
[12:19:40] <XXCoder> trentster: looks nice but not too sure what size it is
[12:19:50] <XXCoder> nema23? 35? some other huge size I dont know about?
[12:20:09] <fenn> what kind of nema23 stepper motors supposedly cost $270
[12:20:18] <DaViruz> "but we reduced cost and space (and got rid of potential noise problems) by not running the encoder signals to the outside world. "
[12:20:22] <DaViruz> :(
[12:21:29] <fenn> ganzuul: "White Aluminum Oxide - Used on tool steels and mold steels
[12:21:39] <fenn> Pink or Blue Aluminum Oxide - Used on alloyed tool steels
[12:21:45] <fenn> Green Silicon Carbide - Used on non-ferrous materials such as aluminum and carbide tooling.
[12:21:54] <trentster> XXCoder: they have a range nema 23-34 sizes http://www.teknic.com/products/clearpath-brushless-dc-servo-motors/#clearpath_sd_info
[12:22:07] <XXCoder> interesting
[12:22:28] <fenn> i think pink just means extra hard binder
[12:22:42] <XXCoder> my entire cnc electrics cost less than that single motor
[12:22:51] <XXCoder> but then its MUCH more fancy than mine
[12:22:54] <trentster> Did you watch the video with the acrylic rod passing in between a slit of a spinning disk - amazing!
[12:23:48] <fenn> ganzuul: if the wheels have letters and numbers you can probably decode them

[12:24:58] <ganzuul> hmm
[12:25:01] <ganzuul> okay! \o.
[12:25:30] <ganzuul> BTW are servos used in electric wheelchairs? Because I found an abandoned one.
[12:25:47] <XXCoder> that is... weird
[12:25:48] <ganzuul> Has two big motots
[12:26:14] <zeeshan> that is extremely weird
[12:26:32] <ganzuul> ...The wheelchair?
[12:26:36] <Wolf_> not servos, just dc gear motors on wheelchair, with 24v brakes
[12:26:51] <ganzuul> It's next to a hospital dumpster.
[12:27:01] <XXCoder> interesting
[12:27:04] <ganzuul> Hospitals throw out expensive stuff.
[12:27:07] <XXCoder> somethings probably broken
[12:27:14] <XXCoder> or has something on it
[12:27:14] <ganzuul> No battery in it.
[12:27:21] <fenn> i would get the motors at least
[12:27:35] <ganzuul> What can they be used for?
[12:27:43] <fenn> umm, battlebots
[12:27:46] <XXCoder> spindle?
[12:27:53] <ganzuul> hm..
[12:27:55] <fenn> cnc servos i guess
[12:27:57] <XXCoder> not fancy indexable onbe?
[12:28:12] <XXCoder> actually yeah. just need encoders added
[12:28:16] <XXCoder> then it would work
[12:28:23] <XXCoder> controller of some kind
[12:28:42] <fenn> they exhibit torque cogging and have high(er) inertia, but that may not be a problem
[12:28:45] <ganzuul> Eeew! Brushed motors.

[12:30:05] <fenn> i don't see the relevance of that video to anything
[12:30:14] <zeeshan> sat on my chair at work
[12:30:20] <zeeshan> suddenly turned around
[12:30:20] <XXCoder> fenn: yeah I guessed wrong. I did say NM lol

[12:31:14] <zeeshan> i can still work
[12:31:21] <zeeshan> but it hurts :(
[12:31:27] <XXCoder> ganzuul: maybe can convert brushed to brushless if its even possible.

[15:58:02] <Sync> I just bought a full set from my tool dealer here
[15:58:10] <Sync> way cheaper than making my own
[15:59:30] <enleth> Sync: good for you to have a competent tool dealer around
[16:00:03] <enleth> But waterjet cutting is so cheap I can't imagine getting non-chinese hook wrenches cheaper
[16:00:32] <enleth> Getting wrenches that fit a particular machine, made from good steel, and cheap sounds like a win-win
[16:01:32] <Sync> mine were like 4-6€ each
[16:01:41] <Sync> and they are gedore
[16:02:22] <enleth> That's about as much as it would cost to cut them out of good 6mm steel in my area
[16:03:56] <Sync> + your time drawing them
[16:04:12] <Sync> and then finishing them because they have sharp edges
[16:04:58] <enleth> But I can get customs that way.
[16:05:35] <enleth> One of the retaining rings in the b'port is in such a shitty place that a regular hook wrench wouldn't be able to grab it
[16:07:13] <enleth> I can design a much longer, curved handle and then have it bent in two spots on a press
[16:09:15] <enleth> And I can get some wrenches that fit onto a woodruff keyed shaft

[20:05:35] <ganzuul> What is this unaccountable, irrecoverable idiocy of preferring scraping over grinding for producing a master surface plate on the assumption that you ALREADY HAVE a master surface plate??
[20:09:17] <Sync> have you compared a ground plate and a scraped plate?
[20:10:25] <ganzuul> I might have seen a scraped plate once.
[20:11:59] <ganzuul> ...Suppose, what I need is a practice by which my master surface is progressively refined by the way it is used for production.
[20:12:15] <ganzuul> So that it becomes more accurate with time rather than less.

[21:10:43] <enleth> it works if there's a voltmeter connected to the unused output.
[21:10:52] <enleth> fuck if I know why
[21:11:02] <andypugh> I can’t quite bring myself to click the button on the HSM Pro 30-day trial.

[21:13:16] <andypugh> I did, but I don’t know if that will work :-)
[21:13:44] <andypugh> It seems that a fallback might be pay-as-you go Fusion-360
[21:14:20] <andypugh> Certainly $25 for a month of 360 is more tempting than $10,000 for a year of HSM Pro
[21:16:59] <XXCoder> whats limits on trail
[21:17:54] <XXCoder> oh express is free
[21:17:59] <andypugh> the 30 day trial is the full thing, no limits. And the free HSM-Express is OK for many jobs, but this pattern has lots of draft angles.
[21:18:37] <andypugh> Express gives you face, pocket and trace. No fully-3D paths.
[21:19:08] <andypugh> I could probably improvise with Trace and hand-work for this pattern
[21:19:23] <andypugh> But not for the core box, I don’t think.
[21:21:01] <XXCoder> no angled em?

[21:29:10] <andypugh> I could probably set up the draft angle in kinematics....
[21:29:22] <Topy44> does anyone have any SHF8 mounting brackets for 8mm shafts lying around? i can't find any proper technical drawings of it and need some measurements...
[21:29:26] <Topy44> they look like this: http://dump.t44.org/2015-09-26_23-28-42.png
[21:33:22] <andypugh> If the central hole is 8mm you can scale from a drawing and make an educated guess.
[21:34:19] <andypugh> But if you prefer to be sure, there is a drawing here: http://www.zappautomation.co.uk/mechanical-products/precision-round-rails-end-supports/shf-type-precision-round-rail-end-support.html
[21:35:17] <Topy44> except that its not. SHF8 looks different
[21:35:32] <Topy44> its weird, all the drawings and tables show the design of the larger ones
[21:35:39] <andypugh> It says “SHF8” on the drawing…
[21:35:40] <Topy44> but the 8mm one looks like the image above
[21:36:28] <Topy44> also the thing i want to know is not in that table
[21:36:36] <Topy44> it appears to have a counterbore
[21:36:39] <andypugh> You can be faiirly sure about the important dimensions like hole centres though.
[21:37:01] <Topy44> and i want to know its size - as in the image it looks like its too small for a standard M5 socket hea
[21:37:01] <Topy44> d
[21:37:42] <andypugh> The upper one looks to have a counterbore, the bottom one doesn’t
[21:38:05] <andypugh> (It’s the other way round, but still)
[21:38:38] <Topy44> yeah pretty sure thats just the back side
[21:39:28] <Topy44> its actually important for the thing i'm designing, as if it doesn't have a counterbore i don't have enough room for the head
[21:39:40] <Topy44> (or if that counterbore is some odd format)

[21:53:37] <Topy44> i ordered some but it will be 4-6 weeks until they are here - and i want to have the design ready by then
[21:54:24] <Topy44> i actually asked several chinese sellers of those things if they had more measurements or technical drawings, but the answers were generally incoherent and useless :
[21:54:25] <Topy44> :)
[21:55:10] <Topy44> some sent an attached picture that was already in the item description, some linked the same dimensions table, and some just answered with random gibberish

[22:03:37] <Topy44> yeah
[22:03:58] <Topy44> also i noticed it helps to learn which formulations they use and use the same, even if they don't seem to make sense
[22:04:10] <Topy44> because they translate them back to chinese and they make sense again :)
[22:04:48] <Nick001-shop> Topy44> you there?
[22:05:20] <Topy44> yeah
[22:05:34] <Nick001-shop> what measurements do you need?
[22:05:54] <Topy44> most importantly the diameter and depth of the counterbore on the mounting holes
[22:06:23] <Nick001-shop> it seems to be for a 4mm cap screw
[22:06:24] <renesis> mcmaster doesnt carry them?
[22:06:31] -!- Komzpa has quit [Remote host closed the connection]
[22:07:08] <Topy44> Nick001: ah! interesting, as the table claims the mounting hole to be for an M5 screw
[22:07:11] -!- chris_99 has quit [Quit: Leaving]
[22:07:13] <Topy44> also, a quick check that the other dimensions are correct would be good - distance between mounting holes especially
[22:07:35] <Topy44> as well as total outer height and width
[22:07:37] <Nick001-shop> dia 0.218 thru cd 0.288x0.185dp
[22:07:52] <Topy44> umh...
[22:08:09] <Topy44> oh, right, imperial... lets see...
[22:08:41] <Topy44> wait... that doesn't make sense
[22:08:43] <Nick001-shop> sorry about the imperial measurements but I'm an american
[22:08:46] <Topy44> yeah
[22:08:58] <Topy44> i'm trying to make sense of those numbers
[22:09:00] <XXCoder> or citzen of 2 other countries lol
[22:09:44] <Nick001-shop> that 4mm screw has a mile of clearance
[22:09:47] <Topy44> whats "cd" and "dp"?
[22:10:18] <Nick001-shop> counter bore and depth
[22:10:35] <Topy44> ah, right
[22:10:36] <Nick001-shop> cb -)
[22:10:39] <Topy44> and diameter of the hole
[22:10:45] <Topy44> now the numbers make sense :)
[22:11:03] <Nick001-shop> 0.218 for the screw hole
[22:11:10] <Topy44> yeah, got it
[22:11:27] <Topy44> thats about right for what it says in the drawing
[22:11:36] <Topy44> thanks!
[22:11:43] <andypugh> http://www.roymech.co.uk/Useful_Tables/Screws/cap_screws.htm
[22:12:10] <andypugh> Means that the hole is too big for M4, and the counterbore is too small for M5
[22:12:17] <Topy44> yeah thats what i thought
[22:12:20] <Topy44> odd
[22:12:24] <andypugh> Personally I would re-counterbore.
[22:12:29] <Nick001-shop> 1.246 center distance for the 2 screw holes
[22:12:53] <andypugh> That nearly matches the quoted 32mm
[22:13:25] <Topy44> yeah thats probably within measurement error or manufacturing tolerance
[22:13:33] <Nick001-shop> what is the head diameter for a 5mm cap screw
[22:13:50] <Topy44> 8.14-8.5 according to that table above
[22:13:55] -!- almostworking has quit [Quit: Textual IRC Client: www.textualapp.com]
[22:14:16] <Topy44> i think there are "slim" head types, i'll check some catalogues
[22:14:44] <Nick001-shop> they're leaving plenty of adjusting room
[22:15:48] <Nick001-shop> thats thinning that out pretty good
[22:15:48] <t12> https://www.dropbox.com/s/lr4pc42ao1wv95l/20150926-20150926-_9260137-1600-90.jpg?dl=0
[22:15:53] <t12> those are some small solder cups
[22:17:14] <Nick001-shop> BTW the used a drill point for the counter bore - not a flat bottom for a screw head to rest on
[22:17:30] <Nick001-shop> the/they
[22:17:53] <Topy44> right
[22:18:04] <Topy44> so probably best not to use it as a counter bore
[22:18:15] <Topy44> maybe i'll just use them backwards
[22:18:42] <Topy44> anyway, thanks a lot!
[22:19:02] -!- almostworking [almostworking!~almostwor@unaffiliated/almostworking] has joined #linuxcnc
[22:19:19] <Nick001-shop> put a heavy flat washer under the head and it should work OK
[22:19:49] <Topy44> nah i'll just mount them them backwards
[22:19:57] <Topy44> there is a proper edge on the other side
[22:20:01] <Topy44> for an M5 screw
[22:21:18] <Nick001-shop> I would check the squareness of the 8mm hole to the faces
[22:21:32] <Topy44> oh, is it a problem on yours?
[22:21:42] <andypugh> t12: The four-pole Lemo 00 size are a nightmare
[22:22:15] <Topy44> damn cheap chinese manufacturing. its always a 50:50 chance if you get something perfectly decent or something that is just a visual approximation of the actual item :)
[22:23:03] <Topy44> i got some horrific ball bearings a few days ago, i have thrown out bearings as "worn out" that were better than those are new :)
[22:23:16] <andypugh> t12: https://www.flickr.com/photos/jaymis/7941618520 but at least there are none in the middle.
[22:23:46] <andypugh> Topy44: Did you buy C4 by mistake?
[22:26:44] <Nick001-shop> I haven't checked - the one face has machining marks on it,so it may have been machined with the bore. Measuring the the faces has about 0.005" difference. You may have to use them the way they were machined-just use a heavy washer to cover up the counter bore.
[22:27:14] <Topy44> Nick001: oh, right, now i understand what you mean. yeah, good point.
[22:28:09] <Topy44> andypugh: no i think i just bought rubbish :)
[22:28:18] <andypugh> Or machine the counter-bore correctly. 8.5mm drill first, then an 8.5mm drill ground to a flat end will work.
[22:28:41] <andypugh> Using a cordless hand drill, even.
[22:28:46] <Topy44> yeah i have flat end drills
[22:29:32] <andypugh> Start with a normal one to aid concentricity. (and tomorrow I will tell you how ti suck eggs)
[22:29:36] <Nick001-shop> Wait till you get bearing blocks with the bearings - 0.005" play on a hard shaft. I was lucky to get my money back on them.
[22:29:51] <Topy44> wow
[22:29:58] <Topy44> yeah i ordered some of those
[22:30:03] <Topy44> however, i ordered adjustable ones
[22:30:45] <Topy44> (assuming you are talking about linear bearings)
[22:31:11] <Topy44> and for another project i ordered the regular ones with the crappy chinese bearings, however i don't plan on using the bearings, i'll put misumi bearings in the blocks
[22:31:30] <Nick001-shop> I got some of them too - The bearing isn't quite parallel to the mounting surface, Good luck-)
[22:31:39] <Topy44> as the chinese bearing blocks including bearings and shipping are still much much cheaper than a misumi bearing block, but a misumi bearing isn't expensive :)
[22:31:46] <Topy44> ugh.
[22:31:48] <Topy44> heh
[22:31:50] <Topy44> ah well
[22:31:57] <Topy44> if they turn out to be rubbish... its not much money lost
[22:32:50] <Nick001-shop> Just time and effort - maybe you'll get a good supplier.
[22:33:12] <Topy44> the adjustable ones were slightly more expensive - but at around 4$ per block including bearing its still not exactly a fortune :)

[22:53:54] <Wolf_> all good till I did a solid front axle swap, had to put too much lift on the truck and some stuff wouldnt clear due to my axle choice
[22:54:29] <XXCoder> tiwake: yeah there was first 3d printed car recently
[22:54:53] <MacGalempsy> remember yesterday when we were talking about the renishaw sls?
[22:55:22] <MacGalempsy> well today, I read an article about the new fastest car attempt, and they were making the parts for it with the Renishaw sls

[22:58:02] <tiwake> hmm
[22:58:11] <tiwake> I'm not seeing what they want for a custom built car
[22:58:27] <tiwake> necessary to get a license plate for
[22:58:44] <tiwake> http://www.dmv.org/or-oregon/other-types-of-vehicles.php#Custom-Built-Vehicles
[22:59:04] <tiwake> it wouldent be a reconstruction or replica
[22:59:35] <tiwake> emissions testing better not be required
[22:59:48] <tiwake> just says "if required"
[22:59:49] <XXCoder> Assembled, Reconstructed or Replica Vehicle Certification
[22:59:53] <XXCoder> first is assembled
[23:00:00] <XXCoder> meaning one you built yourself
[23:00:30] <XXCoder> there is some odd laws
[23:00:45] <tiwake> XXCoder: but if you look at the forum, it does not meet the requirements
[23:00:45] <XXCoder> like requiring windowwipers but not requiring any windscreen
[23:00:50] <Wolf_> most people find something to use as a “donor” for vin and whatnot
[23:02:06] <tiwake> one of these days some state is going to ragequit on the federal government
[23:02:42] <XXCoder> texas almost did lol
[23:02:58] <tiwake> yeah, texas would be the best off of all states
[23:03:17] <tiwake> when they more seriously consider it, or actually do it, I'm moving
[23:03:17] <XXCoder> big state or tiny country
[23:03:45] <tiwake> immigrate to the country of texas... lol
[23:03:58] <XXCoder> yeah better be grandfathered in than immigrate
[23:04:06] <XXCoder> bet you would be called usa names
[23:04:15] <tiwake> lol
[23:04:17] <XXCoder> hurry hurry move there
[23:04:25] <tiwake> XXCoder: you live in texas?

[23:06:09] <tiwake> at the top of the page, the list of requirements
[23:06:25] <tiwake> a custom built car does not meet any of those requirements
[23:07:03] <XXCoder> theres people at east oregon and washington that want to split into new state or join idaho
[23:07:22] <tiwake> I could see that
[23:08:02] <andypugh> In the UK (incidentally a country rather smaller than Texas) you can get “Single Vehicle Approval” which requires an approved engineer to say that the vehicle is safe on the road and meets applicable laws.
[23:08:23] <Wolf_> tanks are included in that
[23:08:52] <tiwake> oh, on the second page it defines what assembled means
[23:09:03] <tiwake> so that is the "right" forum
[23:09:08] <XXCoder> reading
[23:09:46] <XXCoder> 3d printed would fall under assembled
[23:09:52] <tiwake> yeah
[23:10:32] <XXCoder> dont seem to be too complex
[23:10:41] <tiwake> oh and it defines the major parts at the very bottom

[23:14:48] <XXCoder> heh if it says freedom its trying to sell you something. but reading
[23:15:09] <XXCoder> interesting
[23:15:19] <tiwake> there is another internal combustion engine that looked interesting, its a rotary, but not the same action
[23:15:23] <XXCoder> small enough that you can make car that has one of those for each wheel
[23:15:44] <XXCoder> that would make for riciously powerful car
[23:15:50] <tiwake> oh hey, interesting idea
[23:16:06] <Wolf_> don’t those motors make for a bad day if the air/fuel mix is off?
[23:16:07] <tiwake> would need a transmission/clutch of some sort on each wheel though
[23:16:27] <tiwake> Wolf_: isnt that the case for all internal combustion engines?
[23:16:33] <tiwake> (including rocket...)
[23:16:44] <XXCoder> yeah probably some sort that uses planetary gearing system to make it MUCH more compact.
[23:16:54] <Wolf_> well, not running right vs melting down
[23:16:57] <XXCoder> Wolf_: yeah applies to everything
[23:17:02] <XXCoder> motor anyway lol
[23:17:22] <XXCoder> smart engine adjusts air input
[23:17:30] <XXCoder> so mix is correct under most cases
[23:17:50] <tiwake> I would think an electric motor would be better suited for driving each wheel, rather than mechanical motion from combustion
[23:18:06] <XXCoder> tiwake: yeah and theres one concept car that does exactly that,
[23:18:15] <XXCoder> pretty darn effective

[23:20:17] <XXCoder> wow
[23:20:21] <XXCoder> that is weird andy
[23:20:34] <tiwake> ooo... why not make it hydraulic driven?
[23:20:44] <tiwake> or is that too high speed for hydraulics?
[23:21:36] <andypugh> one drawback of the Megola seems to be that you can’t stop

[23:23:01] <tiwake> Wolf_: could if there is a clutch at each wheel...
[23:23:21] <tiwake> could the hydraulics also be used as a brake?
[23:23:31] <XXCoder> andypugh: makes sense I guess. no way to have any input to engine

[23:25:16] <tiwake> lol
[23:25:27] <Wolf_> naa, I want the recon/command variant
[23:26:14] <Wolf_> 120 mm is way big for them little tanks
[23:26:26] <tiwake> hydraulic would give a serious amount of torque from a standstill
[23:26:57] <Wolf_> http://www.armyjeeps.net/FV101-0714/index.htm
[23:27:48] <SolarNRG> hydraulics are also slow
[23:28:14] <XXCoder> umm
[23:28:16] <tiwake> SolarNRG: slow for what?
[23:28:21] <XXCoder> is that plastic pipe in second one
[23:28:28] <Wolf_> yeah
[23:28:43] <Wolf_> can’t really import it with a real cannon lol
[23:28:44] <malcom2073> We had a hydraulic driven robot that was capable of 40mph
[23:28:53] <XXCoder> makes sense
[23:28:56] <malcom2073> And that was in the 90's
[23:28:59] <malcom2073> bet you can go faster now
[23:29:13] <SolarNRG> depends what ur trying to do, if you're operating a minidigger and want to excavate a site, hydraulics are the way to go, but cnc often uses either steppers or servo
[23:29:17] <XXCoder> Wolf_: slow invasion plan - immgrants buy a tank one a time and rebuild it

[23:33:16] <SolarNRG> I doubt you could make an engine better than some of the sports car manufacturers
[23:33:45] <SolarNRG> And if you want a fast car, do what the thrust 2 ssc team did, fire all the automotive engineers, hire aerospace engineers
[23:34:03] <SolarNRG> I mean what do you want in a car?
[23:34:26] <SolarNRG> Is it for city use, country road, motorway, mountain, offroad, warfare?
[23:34:45] <tiwake> SolarNRG: no... I just want a car that isnt dumb, as far as I know you cant buy such a thing new anymore... by dumb I mean the computer system, engines not designed to be fixed, difficult to get to oil filters, transmission that is underbuilt... etc. etc.
[23:35:06] <malcom2073> tiwake: Buy any car over $100k and you get all that fwiw
[23:35:15] <tiwake> thats not new though XD

[23:35:52] <tiwake> misread
[23:35:56] <SolarNRG> tiwake, I see so basically you want a car that doesn't have planned obselecense, isn't hackable and is easily maintainable, might I suggest you buy yourself a vintage British Triumph 1960s era motor?

[23:38:14] <DaViruz> designing a car is not a very trivial task. you run in to a lot of problems of things being in the way of other things, things wearing more then you expected etc
[23:38:25] <SolarNRG> A jet in the back isn't a brilliant suggestion for inner city use, I expect it would end up with a lot of shouting, arm waving, insurance payouts, police flashy lights etc.

[23:39:16] <SolarNRG> DaViruz, I expect if you're happy enough making a car that's not as good as what you can buy, open source 3d modelling could allow you to make your own car, in fact there's no reason for you to not use existing parts, 3d scan them and incorporate them into your model
[23:39:47] <SolarNRG> however teams of technicians have ingeniously found ways to compact so much stuff under that hood in ways you probably wouldn't have dreamed of in decades
[23:40:03] <tiwake> thats the problem though
[23:40:13] <SolarNRG> I mean even engineering a 1907 car from scratch would be a work of genius in your own garage
[23:40:15] <tiwake> compacting everything in so you cant really work on it

[23:43:20] <malcom2073> Sorry, my question was for tiwake

[23:43:31] <SolarNRG> how many thousands of crash dumies paid the ultimate price?
[23:44:10] <SolarNRG> I accept the car manufacturers don't want you to have a car that would last forever
[23:44:21] <tiwake> malcom2073: both really... design as I go... but its just a thought experiment at the moment
[23:44:34] <malcom2073> I thought you weren'tbuilding your own engine?
[23:44:38] <SolarNRG> I accept that because of design over-complication it has given jobs to trained mechanics and people who train the mechanics

[23:44:56] <tiwake> correct, I dont want to build or design my own engine :P
