[01:07:23] <Tom_itx> why is 'RUN FROM HERE' greyed out?
[01:07:32] <Tom_itx> what mode do you ned for that to work?
[01:08:16] <Valen> probably out of estop i think
[01:08:33] <Tom_itx> can it be any line?
[01:08:39] <Valen> i dunno
[01:08:46] <Valen> i've only ever done it on G1s
[01:08:47] <Tom_itx> within sensible reason
[01:08:51] <Valen> but i dont see why not?
[01:09:05] <Tom_itx> doesn't estop require re homing?
[01:09:11] <Tom_itx> maybe not
[01:10:51] <Valen> you don't *need* to home for anything
[01:11:11] <Valen> entering and leaving estop is penalty free i believe
[01:11:15] <Tom_itx> ok why didn't the program stop for a tool change?
[01:11:23] <Tom_itx> do i not have a parameter set right for that?
[01:11:26] <Valen> we always go into estop so the servo drives shut down
[01:11:34] <Valen> tool changes are hinky

[01:11:51] <Valen> have you specified its a manual tool change?
[01:12:06] <Tom_itx> no i haven't done any tool change setup stuff
[01:12:15] <Tom_itx> that's why i'm test cutting air :)
[01:12:21] <Valen> i *think* just the gcode does it for you
[01:12:25] <Tom_itx> no
[01:12:31] <Valen> personally we split the gcode into sections
[01:12:38] <Tom_itx> i'm used to specifying a Tx M6 and that didn't work
[01:12:39] <Valen> i mean there are a number of tool change gcodes
[01:12:51] <Tom_itx> i always use that one
[01:13:17] <atom1> N319 G49 G28 Z0
[01:13:17] <atom1> N320 T2 M06 ( .0625 END MILL )
[01:13:17] <atom1> N321 G17 G00 G90 X-1.5785 Y-1.1843 S2800 M03
[01:13:17] <atom1> N322 G43 Z-0.9 H2
[01:14:04] <Tom_itx> but it didn't stop for the tool change
[01:16:18] <Tom_itx> http://www.linuxcnc.org/docview/html/gui/axis.html#sec:Manual-Tool-Change
[01:16:58] <Tom_itx> looks like i need to add that to my hal file
[01:17:40] <Tom_itx> i suppose most guys that do manual tool change also use touchoff
[01:17:50] <Tom_itx> i preset the tools and put them in the tool table
[01:18:12] <Tom_itx> as per what i'm used to on a 'real' machine environment
[01:19:18] <Tom_itx> so where do i find the sim files?
[01:19:32] <Tom_itx> i didn't copy any preconfigured configs that i know of
[01:23:04] <Valen> manual tool change with touch off is hard for emc i believe
[01:23:15] <Valen> as you cant jog during execution as a rule
[01:23:31] <Tom_itx> i don't need to
[01:23:47] <Tom_itx> it returns to Z zero where i insert another holder
[01:23:51] <Tom_itx> preset
[01:24:19] <Valen> as i said we just split the tools into seperate gcode files
[01:24:26] <Valen> its just easier lol
[01:24:41] <Tom_itx> i'll figure it out
[01:24:48] <Tom_itx> i hope
[01:24:53] <Valen> eventually we want to make a spindle
[01:25:01] <Valen> it will have automatic tool changing
[01:25:55] <Tom_itx> i wish somebody would fix the search page so the google results are at the top instead of after the left side bar
[01:34:04] <r00t4rd3d> the whole website needs professional work.
[01:34:30] <r00t4rd3d> or at least someone who knows what the hell they are doing
[01:37:02] <atom1> i wonder if those nets need to be loaded from a separate hal file
[01:37:21] <atom1> http://www.linuxcnc.org/docview/html/hal/hal-examples.html#_manual_toolchange
[01:37:27] <atom1> i can't tell
[01:37:40] <atom1> i copied those lines in and get errors
[01:42:00] <atom1> ok i must have had some other tool change lines defined
[01:42:09] <atom1> now to give it a try
[01:51:10] <Tom_itx> that did the trick
[01:54:36] <Tom_itx> it pops up a dialog box with a button to continue
[01:54:50] <Tom_itx> as advertised
[01:55:11] <Tom_itx> Valen, you should try it
[01:55:26] <Tom_itx> unless you have to change collets and can't
[01:57:09] -!- ve7it has quit [Remote host closed the connection]
[01:58:29] <Valen> we have collets so need to re-zero anyway
[01:58:43] <Tom_itx> wouldn't help you then
[01:58:52] <Tom_itx> unless you switch to tool holders
[02:08:11] <atom1> mmm, it doesn't like my G49 at the end of the file
[02:10:48] <atom1> i better fix that in the post template

[02:55:28] -!- adb has quit [Ping timeout: 245 seconds]
[02:56:16] <uw> hello question about half stepping and full stepping for steppers. The motor driver has two pins that when driven low are high can associate STEP pulses as quarter, half or full, depending on the input
[02:57:06] <uw> say 0-0 = full step , 0-1 = half step , 1-0 = quarter step, 1-1 = no step
[02:57:58] <uw> I have them assigned as "I/O output" on the step config wizard, pins 14 and 16 of my parallel port
[02:58:38] <uw> So, my question is how can i drive them low to enable table movement?
[02:58:58] <uw> as it stands now they are floating (1-1) so the table doesnt move
[02:59:30] <jdhNC> you can put pulldowns on them
[02:59:42] <uw> i would normally just physically tie them to ground with wire and that worked, but I am looking for a software solution if possible
[02:59:51] <Valen> why?
[03:00:07] <Valen> why not just tie them to quater step?
[03:00:14] <jdhNC> do you have some need to switch stepmodes on the fly? Why not just hardwire them to what you want.
[03:00:15] <Valen> use the i/os for something else?
[03:00:54] <uw> jdhNC, Valen ok so i guess this is a "best practice" question here as well, as im pretty new to this
[03:01:11] <uw> Typically, does linuxcnc change the step mode?
[03:01:12] <jdhNC> what drives are they?
[03:01:13] <uw> or can it?
[03:01:22] <Valen> *generally* people report smoother movements at higher levels of microstepping
[03:01:45] <jdhNC> it can set IO lines. Never heard of anyone switching stepmodes that way though.
[03:01:48] <Valen> it would be possible, to have different configs for different step rates
[03:01:56] <Valen> but you couldn't change it on the fly
[03:02:06] <Valen> well at least i dont think you could
[03:02:10] <jdhNC> you could, your scale would just be off :)
[03:02:17] <Valen> (well you could change it, but i dont think emc could handle it)
[03:02:26] <Valen> thats what i was trying to say
[03:02:54] <uw> ok so i guess theres no really need to switch to course mode (full step)?
[03:03:01] <jdhNC> no.
[03:03:08] <Valen> unless your running into issues with step rate (ie physically getting enough pulses out of the computer) I'd just tie to to the finest mode your driver can handle
[03:03:15] <jdhNC> if you need full step mode for torque, you need to leave it there.
[03:03:17] <uw> ok thanks (sorry, super noob here lol)
[03:03:39] <Valen> quater step would still have the same torque when you get to the poles though jdhNC?
[03:03:42] <jdhNC> if you change from say full to half, your distance travelled would also drop in half
[03:04:04] <uw> the driver btw is called "opti step" from microkenitcs (cant find any info on it)
[03:04:22] <Valen> I'm after a teensy stepper driver, the more micro steps the better
[03:04:28] <jdhNC> Valen: there is a nice paper somewhere on torque vs. uStep modes
[03:04:43] -!- adb [adb!~adb@178-211-226-40.dhcp.voenergies.net] has joined #linuxcnc
[03:04:58] <jdhNC> http://www.microkinetics.com/pdfmanuals/OptiStep.pdf
[03:05:05] <jdhNC> that?
[03:07:36] <Valen> i can see the torque would follow a sine curve when microstepping
[03:07:39] <uw> well, that is the similar (but pin incompatible) successor of the unit. it is called "opti driver" and is in a paxton patterson CNC training mill. was made in 1994
[03:08:14] <uw> i was able to get 2 pages off archive.org for the thing, as they have since yanked it from the website

[03:09:47] -!- _1SheYode has quit [Ping timeout: 252 seconds]
[03:10:05] <Valen> yeah the incremental torque to use their nomenclature
[03:10:25] <Valen> but when you hit the poles it is still full torque
[03:12:19] <Valen> the advantage to microstepping isn't so much the increased resolution, its smoother operation and fewer harmonics
[03:12:54] <Valen> rather than "hitting" it every time it steps it will smoothly push from one to the next, so your less likley to excite a resonance
[03:12:58] -!- norias has quit [Ping timeout: 244 seconds]
[03:13:15] <uw> ok so i will just adapt my cable and leave it as always microstepping. btw this is what ive had before and it did work fine. I just wasnt sure if it would be more efficient (faster) if linuxcnc would control the step rate
[03:13:55] <Valen> what is limiting your speed?
[03:14:45] <Jymmm> physics
[03:14:45] <uw> I am guessing torque of the motor but really i havent used it much yet to say for sure
[03:15:15] <uw> i was thinking that maybe full stepping would make it faster for some reason
[03:15:17] <Valen> *generally* available voltage sets your top speed
[03:15:22] <uw> looking back, that doesnt make much sense
[03:15:32] <Valen> well it is a common result

[03:15:50] <uw> hmm
[03:15:56] <Valen> microstepping makes things smoother so its less likley to loose a step when your going faster
[03:16:23] <uw> the unit has a fixed 5v supply and i havent tried messing with it yet. Im not sure the opti driver supports much higher (cant find documentation on it)
[03:16:50] <Valen> 5v? is it for writing on dvd's with a texta or something lol
[03:17:03] <Valen> 5v for logic sure
[03:17:39] <Valen> but steppers are usually 12v at least? (i could be wrong but i am pretty sure the low end geckos drop out at 11 and a bit)
[03:18:59] <uw> ok just went and checked it out
[03:19:15] <uw> the motors say 6V
[03:19:19] <Tom_itx> ok got the first good part off using linuxcnc
[03:19:42] <Valen> that will be the voltage you put through them for holding
[03:19:50] <uw> howeer the power supply also made by microkinetics says 36V
[03:19:51] <Tom_itx> post is fixed i think, figured out the tool change in hal, set all the tools in the tool table
[03:19:52] <Valen> IE if you feed them 6v you can't break them ;->
[03:19:57] <Valen> yes thats more like it
[03:20:25] <uw> ok also it is a sherline CNC mini mill
[03:20:40] <uw> packaged in some bootleg training center, which houses the opti stepper
[03:20:45] <Tom_itx> the 203v needs 18 to 80v
[03:21:02] <Tom_itx> uw, so is mine
[03:21:17] <uw> lol is the case red?
[03:21:30] <Tom_itx> just finished updating the psu steppers and drivers

[03:25:37] <Tom_itx> there's mine
[03:25:53] <uw> btw Valen jdhNC thank you for your help
[03:25:59] <Valen> nw
[03:26:07] <Tom_itx> looks a bit different now that it's rewired with larger steppers
[03:26:22] <Valen> awww its cute Tom_itx ;-P
[03:26:31] <Tom_itx> it works
[03:26:48] <Tom_itx> i'd rather have a full size one in a nice air conditioned shop
[03:26:50] <Valen> i'm just raggin on yer
[03:26:53] <Tom_itx> i know
[03:27:04] <Tom_itx> the process is still the same
[03:27:06] <Valen> direct drive on the steppers hrm
[03:27:16] <Tom_itx> they do ok
[03:27:30] <Tom_itx> i get about 80 ipm which is more than it can feed while cutting
[03:27:31] <Valen> i would have thaought belt reduction for more acceleration
[03:27:48] <Valen> acceleration seems to be the real figure of merit these days
[03:27:58] <Valen> at least for me
[03:28:04] <Tom_itx> i was getting about 20 to 25 max before
[03:28:14] <Tom_itx> so i'm happy with the upgrades
[03:28:14] <Valen> that might have been a bit low
[03:28:27] <Valen> what size are the ones in the pics 17?
[03:29:55] <Tom_itx> 23
[03:30:02] <Tom_itx> i went with 23 doublestack
[03:30:03] <Valen> you went bigger than 23?
[03:30:05] <Valen> wow
[03:30:23] <Valen> seems like overkill somehow
[03:30:31] <Tom_itx> why?
[03:30:50] <Valen> i *think* i see people driving bridgeports with 23s
[03:30:59] <Tom_itx> i don't think so
[03:31:17] <Tom_itx> http://www.kelinginc.net/NEMA23Motor.html
[03:31:21] <Tom_itx> #3 there
[03:31:24] <Tom_itx> is the one i have
[03:31:33] <Tom_itx> 282 oz in
[03:31:55] <Tom_itx> bp would take 400 to 500 i would think
[03:31:58] <Tom_itx> maybe more
[03:32:13] <Tom_itx> these aren't ballscrews either
[03:32:32] <Valen> they normally run a 4:1 reduction
[03:32:35] <Valen> and perhaps more volts
[03:32:41] <Valen> and ballscrews
[03:32:57] <Tom_itx> i'm at 50v now
[03:33:07] -!- norias has quit [Ping timeout: 244 seconds]
[03:33:08] <Tom_itx> was 25 or thereabouts
[03:33:13] <Valen> you actually using the 50v?
[03:33:27] <Tom_itx> it's wired to the stepper drivers
[03:33:45] <Valen> i meant how much voltage is the driver giving to the motors during a rapid
[03:33:55] <Tom_itx> i dunno how to tell
[03:34:02] <Valen> scope it
[03:34:02] <Tom_itx> it's current limited to 3.5A
[03:34:22] <Tom_itx> the steppers are rated for 4.2
[03:34:43] <Valen> the psu is limited or the driver?
[03:34:48] <Tom_itx> the driver
[03:34:59] <Tom_itx> current limit resistors on each one
[03:35:30] <Tom_itx> they don't run hot, just warm to the touch
[03:35:34] <Tom_itx> the steppers get warmer
[03:35:44] <Tom_itx> but not any warmer than they used to
[03:35:55] <Valen> they shouldn't really
[03:36:09] <Valen> current limit resistor is probably a sense resistor
[03:36:13] <Valen> .0something ohms
[03:36:21] <Valen> (well hopefully lol)
[03:36:24] <Tom_itx> it's user selectable
[03:36:31] <Tom_itx> i put a 47k on it
[03:36:33] <Tom_itx> iirc
[03:36:49] <Valen> yeah, that'll be some kind of amplifier then
[03:37:08] <Tom_itx> it's quite a driver i think
[03:37:25] <Valen> http://finance.groups.yahoo.com/group/geckodrive/message/21085
[03:37:26] <Tom_itx> 1 sec after the last pulse is received it drops the current by 71%
[03:37:46] <Valen> using nema 23 steppers on a bp
[03:38:37] <Tom_itx> there are lots of different nema23 steppers though
[03:38:42] <Valen> true that
[03:39:02] <Tom_itx> some as high as 570 in oz

[03:39:06] <Valen> I'm trying to work out if i should go steppers or servos for our new mills
[03:39:08] <Tom_itx> look on the kelinginc page
[03:39:11] <Valen> we like servos
[03:39:19] <Valen> but they are spendy :-<
[03:39:22] <Tom_itx> i would to but these are cheaper
[03:39:34] <Tom_itx> and especially for this little mill
[03:39:50] <Tom_itx> i think it's working about as good as it can now
[03:40:04] <Tom_itx> beyond a mill upgrade
[03:40:12] <Valen> if it does what your after then its all good
[03:40:24] <Tom_itx> i'm always after more
[03:40:35] <Valen> our new mill is going to be 5 axis of stainless steel coated epoxy granite filled goodness ;->
[03:40:46] <Tom_itx> it's why i went with the drivers i did, so i can use them if i do upgrade

[11:52:29] <Tom_itx> jthornton, what about 6:52?
[11:52:50] <Tom_itx> sleep much more and the day will be over
[11:53:31] <archivist> probably got woken by the dog whining about breakfast
[11:53:49] <jthornton> I'm usually up at 5:01
[11:53:51] <Tom_itx> cut my first parts off using linuxcnc last night after fixing the manual tool change code
[11:54:00] <jthornton> nice
[11:54:02] <Tom_itx> thanks to you and others here
[11:55:14] <Tom_itx> finally got my cam post tweaked the way i want it and figured out what the tool table expects for tool offset entries etc
[11:55:45] <Tom_itx> apparently most here who use manual tool change use touch off
[11:57:49] <jthornton> I'm sure I don't understand the last statement
[11:58:41] <Tom_itx> setting one tool at a time during machining instead of setting them all at once and entering them in the tool length offset in the tool table
[11:58:55] -!- rob_h has quit [Quit: Leaving]
[11:59:00] <Tom_itx> with some sort of touch off device
[12:00:00] <Tom_itx> unless of course they have a tool changer
[12:01:19] <jthornton> the problem is if you don't have some magic Z touch off switch that you probe to after the tool change it doesn't make sense to even use the tool table if your spindle is a collet one
[12:03:21] <Tom_itx> i think that's been brought up here
[12:06:20] <Tom_itx> for example being able to change a tool if it breaks or gets dull then continuing where you left off
[12:07:32] <jthornton> yea, there has been a lot of discussion on that subject
[12:07:58] <Tom_itx> it's one thing i see lacking over conventional cnc's
[12:09:49] <archivist> conventional users can afford a stack of pre set tools in holders
[12:10:00] <Tom_itx> yup
[12:10:41] <Tom_itx> those are not typically your hobyist machines
[12:10:44] <archivist> and some tools defy easy touch off
[12:11:27] <Tom_itx> yeah, i've had some cutters i wasn't really sure how to code for in my cad cam too
[12:11:45] <Tom_itx> at least to make the model look right
[12:11:53] <jthornton> what kind of cutters?
[12:11:58] <Tom_itx> tapered cutters
[12:12:03] <archivist> gear cutters
[12:12:56] -!- robin_sz has quit [Ping timeout: 246 seconds]
[12:12:58] <Tom_itx> or radius cutters
[12:13:10] <Tom_itx> is another one that makes you stop and go hmmmm
[12:13:47] <jthornton> you mean like convex radius end mills?
[12:13:58] <Tom_itx> not ball nose
[12:14:28] <Tom_itx> for outter corner radius
[12:14:58] <Tom_itx> on some parts we would let the cnc help us debur
[12:15:02] <jthornton> yea, you gotta know the tip diameter of them
[12:15:49] <archivist> on a gear cutter you want the centre line and pcd
[12:15:58] <Tom_itx> it's one of those things that just doent look right in the cad model
[12:17:12] <Tom_itx> then you go back 6mo later and look at it and wonder wtf that tool path is for
[12:18:38] <jthornton> lol
[12:19:14] <jthornton> I usually just create new tool paths unless it is a part that I do often and I've not found one of them yet
[12:19:24] <Tom_itx> sometimes you just hope the operator is smart enough to make adjustments at the machine
[12:19:32] -!- mozmck [mozmck!~moses@client-] has joined #linuxcnc
[12:20:30] <Tom_itx> when we did work for experimental it was like that. just make sets of 6 of every part and you may never see it again
[12:21:35] <archivist> mass production! /me usually making one offs
[12:21:58] <jthornton> I have one thing that I make that is up to 10 sets now! the rest are usually 1
[12:22:34] <Tom_itx> the gravy is when you can just shove the file out to the machine and turn it over to the operator
[12:23:26] <Tom_itx> in which JT-Shop's case he would just change hats and take a few steps
[12:24:34] <jthornton> I gave up on the hats a long time ago and just do everything myself with the one hat on

[16:14:13] <jdhNC> I can paypal postage/materials/etc.
[16:14:27] <Connor> materials isn't a biggie.
[16:14:43] <Connor> Not sure about postage yet.
[16:15:44] <jdhNC> how did you attach your front estop box?
[16:16:27] <Connor> I clamped it to the main box and drilled two holes.. and then tapped them.
[16:16:58] <jdhNC> I was hoping to avoid drilling, but I don't think anything else will hold it securely enough.
[16:17:10] <Connor> drilling the pass-through hole was fun.. I just drilled a spot hole on both parts and drilled them bigger separately.
[16:17:35] <Connor> No real way around it.
[16:18:03] <jdhNC> pass-through what?
[16:18:10] <Connor> When I make my full enclosure, it, along with the main control box will move.
[16:18:58] <Connor> I'm using a DB9 cable up to main e-Stop box. I have a break-out inside to pass pwm into it.. and I need to bring the 120v line down into it for the AC relay.
[16:19:46] <Connor> pwm/5v/gnd/ccw relay + 120v from the chip guard switch.
[16:20:05] <Connor> Oh. and the spindle encoders too.

[16:25:56] <jdhNC> I had scavenged a nice sub-panel with terminal strip, SSR and 4PDT relay. Used those for the estop circuit and added another SSR for spindle. It will be energized via an output pin through one of the 4p relay contacts
[16:26:04] <Connor> When/If I decide to do spindle CCW relay.. I'll have a 12v source I can run into the contact on the C43 board to trip it.
[16:26:56] <jdhNC> I'm not sure I care about reversing anymore. A tap head seems like it would be better/safer for tapping and I can't think of any other use.

[16:58:13] <Connor> I need to cover it, because chips can land on top of it.. and cause a pre-mature endstop event. Had it happen already.
[16:59:22] <jdhNC> I saw a pic somewhere that someone had milled out a pocket for the switch and mounted it open-side to the mill for a combo cover/holder
[17:00:04] <jdhNC> my prox switches are too tall (or wrong orientation) to fit on X.

[17:02:51] <Connor> IchGuckLive: Yup. :) To each his own as we say.
[17:03:32] <IchGuckLive> what RPM you want at the spindle
[17:03:32] <jdhNC> I think I will have to take the X back off to mount anything
[17:03:57] <Connor> IchGuckLive: ? For the 4th Axis ?
[17:04:15] <IchGuckLive> you can go flex with a blet 1inch wide over 2 cones
[17:04:56] <IchGuckLive> Belt !
[17:05:53] <Connor> probably somewhere between 2500-3000 RPM on the 4th Axis spindle. Probably 2 modes, one for indexing (low gear) and one for turning high gear

[17:07:56] <Connor> I have a 4" on a R8 that, once I get 4axis built.. I'll remove the R8 arbor from it.. and use it on 4th axis
[17:09:19] <IchGuckLive> so 1HP is a litel low with the MY1020
[17:10:05] <Connor> From my understanding.. Rotary carving isn't hard to do.. You just use the 4th axis as if it's the Y axis.. center the Y axis up correctly and your good to go.

[17:17:27] <IchGuckLive> nice price and the driver from Gecko ?
[17:17:54] <IchGuckLive> The speed is good if you go for Direct
[17:18:04] <Connor> http://www.automationtechnologiesinc.com/products-page/dc-servo-motor-driver
[17:18:10] <IchGuckLive> with a 1000Encoder its perfect
[17:18:23] <Connor> Either the G32-X or that Dugong
[17:18:29] <Connor> G320X
[17:18:37] <IchGuckLive> as i said yesterday
[17:18:37] <jdhNC> the gecko only does step/dir?
[17:18:47] <IchGuckLive> yes step dir
[17:19:36] <Connor> So, it handles the encoders directyly.
[17:20:02] <IchGuckLive> does automotion sell on ebay via paypal or amazon
[17:20:11] <jdhNC> so you have to have a stepgen for speed?
[17:20:25] <Connor> IchGuckLive: They take paypal direct from the site.
[17:20:32] <jdhNC> Ich: they are keling's new name
[17:20:55] <Connor> jdhNC: I think so, you treat it just like a stepper at that point??
[17:22:13] <Connor> 42 oz-in constant torque good enough for 1:1 drive ?
[17:22:46] <IchGuckLive> leadscrew pitch ?
[17:23:00] <Connor> this for spindle drive
[17:23:12] <Connor> driving that 4" chuck.
[17:23:18] <IchGuckLive> no way
[17:23:58] <Connor> Rated at 230 oz-in peak torque / 42 oz-in constant torque

[17:28:38] <Connor> maybe I just use stepper on my rotary table and use the mini lathe for turning.
[17:29:58] <Jymmm> For the record... JB-Weld *DOES* contain iron particles. But they are saying as it cures, the polymer "encapsulates" these particles. That is still yet to be determined as still curing.

[17:45:10] <TekniQue> too liquid
[17:45:18] <TekniQue> great product otherwise
[17:45:20] <Jymmm> hardly
[17:45:53] <Jymmm> it's as thick as axel grease, at least for me.
[17:46:01] <TekniQue> I've had problems with it running away before it cures
[17:46:08] <syyl> tried warming it up?
[17:46:12] <TekniQue> nope
[17:46:17] <syyl> then it should get liquid like water :D
[17:47:20] <TekniQue> if I wait 10 minutes after mixing it, then it's easier to make it maintain its shape
[17:48:01] <TekniQue> jb weld also cures the slowest of all these steel epoxies I've been using
[17:48:26] <Jymmm> TekniQue: it's not crazy glue
[17:48:27] <TekniQue> some of them will be rock hard in 10 minutes
[17:48:47] <andypugh> The 2-part eppoxy putties can be very useful.
[17:48:57] <syyl> many of the "slow" epoxies can be cured faster using heat

[22:03:59] <frallzor> since it was first time yesterday i used it

[22:56:14] <Jymmm> I like the crown... http://www.youtube.com/watch?v=b-fqDz5ouyM&feature=related
[22:56:18] <JT-Shop> we cut mesh wire with one stationary tube and one moving tube with tight fit to shear off the wire
[22:57:07] <JT-Shop> we used a mixmaster to make deep see fishing reels on the rigs
[22:57:28] <Jymmm> JT-Shop: I was thinking something along those lines, with the "cut" operation initiated by a reversal of one of the tubes
[22:58:32] <Jymmm> I still need to fit in there of the clamp and cut so it can begin the next hank after the cut operation.

[23:01:09] <Jymmm> andypugh: interesting, seems simple enough. just have to figure out how to 1) tell it when it's at the end(s), and 2) it's speed of going back and forth.

[23:23:25] <pfred1> andypugh did you see the box of junk I scored last weekend?
[23:23:35] <andypugh> Yes
[23:23:45] <PCW> I'm happy, I can now program totally blank 6I25 with a PCIE utility (something not possible with the 5I25)
[23:23:49] <pfred1> it had a piece of strip board in it
[23:24:14] <pfred1> nice shiny new and untouched
[23:24:49] <pfred1> it has some mystery etched board too
[23:25:30] <andypugh> Is the 6i25 on the market yet? I accidentally bought a PCIe motherboard.
[23:26:03] * JT-Shop wonders what to wipe the top of the anvil down with now that it is not rusty
[23:26:13] <pfred1> paste wax
[23:26:21] <PCW> Yep its available now
[23:26:29] <Tom_itx> any pics of it?

[23:27:58] <PCW> andypugh did you buy a DN2800?
[23:28:15] <pfred1> I did the horn with an angle grinder and flap wheels
[23:28:29] <pfred1> it wasn't as bad as I thought it'd be
[23:29:17] <andypugh> PCW Yes. I can't remeber why, but it seemed a good idea at the time.
[23:29:37] <PCW> it nice with its built in power supply
[23:30:05] <pfred1> I want to get into making switching PSUs
[23:30:16] <Tom_itx> how big?
[23:30:21] <pfred1> I read so much about them they're kind of exciting
[23:30:27] <PCW> and alexander had really good latency results
[23:31:04] <Jymmm> andypugh: you dont like the mobo?
[23:31:10] * JT-Shop went shopping in the automotive section of the garage but sadly found no paste wax
[23:31:32] <pfred1> in PC PSUs the 110-220 switch on the back takes a voltage doubler out of circuit
[23:31:44] <djdelorie> in our local hardware store, it's with floor cleaners
[23:31:48] <pfred1> JT-Shop I live in a swamp now so I'm constantly battling rust
[23:31:49] <Tom_itx> JT-Shop look for your old surfboard and the sexwax by it
[23:31:49] <PCW> Andy we shipped a 6I25 to you yesterday I think
[23:31:52] <JT-Shop> pfred1: nice
[23:32:04] <pfred1> paste wax is a god send
[23:32:08] <Jymmm> djdelorie: JT's garage
[23:32:22] <pfred1> thouth I clear coat lots of stuff too
[23:32:23] <Jymmm> djdelorie: JT's Commesary
[23:32:35] <djdelorie> yeah, but it's not in the automotive section of our hardware store. JT needs to look in the floor cleaner section of his garage...
[23:32:38] <JT-Shop> I use LPS 2 and 3 most of the time and 3 has some wax in it
[23:33:01] <pfred1> i wax my pliers
[23:33:03] * djdelorie uses Butcher's Bowling Alley Wax
[23:33:07] <pfred1> so they don't rust up on me
[23:33:10] <Jymmm> djdelorie: JT-Shop went shopping IN HIS GARAGE, in it's automotive section.
[23:33:23] <pfred1> I got tired of wire wheeling them all twice a year
[23:33:34] <djdelorie> I know. He needs to look IN HIS GARAGE, in the floor cleaner section. Wow, it's hard to get a joke in edgewise around here.
[23:33:40] <JT-Shop> I know I had a tub of it somewhere...
[23:34:06] <Jymmm> djdelorie: It doesn't exist, he never cleaners the floor! DUH!
[23:34:11] <Jymmm> cleans
[23:34:20] <JT-Shop> floor cleaner section only has mops, brooms, floor sweep and vacuum cleaners

[23:35:56] <Jymmm> See all those toxic cleaners are bad for you... bobcat and a dumpster is the way yo clean the floors, desk, etc
[23:36:04] <djdelorie> oak is soft compared to some of the woods I've used
[23:36:18] <djdelorie> but red oak is my preferred wood anyway
[23:36:20] <pfred1> this was well seasoned
[23:36:27] <djdelorie> even so :-)
[23:36:29] <Jymmm> red oak? for what?
[23:36:33] <djdelorie> everything
[23:36:38] <Jymmm> ew
[23:36:41] <pfred1> oak checks too much
[23:36:44] <r00t4rd3d> i like oak too
[23:37:02] <pfred1> poor man's wood
[23:37:03] <Jymmm> I like oak too, but there are lots of others out there too

[23:37:57] <r00t4rd3d> pine, now there some good stuff
[23:38:06] <pfred1> djdelorie mill that yourself?
[23:38:07] <Jymmm> for kindling
[23:38:19] <djdelorie> I buy it rough and dry, and do the finish milling myself
[23:38:30] <djdelorie> otherwise it's not flat enough
[23:38:31] <Jymmm> djdelorie: thats what she said
[23:38:41] <r00t4rd3d> Jymmm, or for building the house your currently living in.
[23:38:52] <pfred1> djdelorie http://i.imgur.com/QPZtB.jpg
[23:39:04] <pfred1> I cut that down myself
[23:39:19] <pfred1> we got awesome oak here
[23:39:24] <djdelorie> a little *too* rough for my taste, but cool anyway. I have a few small bits I milled myself, but nothing big
[23:40:00] <pfred1> yeah not my usual style I was channeling Nakashima
[23:40:26] <pfred1> to think in the 70s I could have bought his stuff for peanuts
[23:40:40] <pfred1> I used ot see him on the sidewalk in New Hope all the time
[23:41:52] <pfred1> he holds the worlds record today for a woodwork piece selling at auction

[23:46:51] <djdelorie> did you check behind the couch?
[23:46:53] <pfred1> I don't think my house is worth what that table sold for
[23:46:56] <JT-Shop> crap my dad had a table that looked like that
[23:47:29] <pfred1> did it say George Nakashima on it?

[23:50:48] <pfred1> there is a house here with a cannonball in it
[23:51:04] <djdelorie> every time I mention my metal lathe to friends, they always ask if I've made a cannon yet.

[23:55:05] <JT-Shop> I stayed in a hotel in Amsterdam on the river that was a warehouse during the sailing days and had some huge timbers that made up the frame work
[23:55:12] <r00t4rd3d> JT-Shop, find a way to mortar an egg
