[00:17:27] <zeeshan> XXCoder: you there?
[00:17:33] <XXCoder> yep whats up
[00:17:36] <zeeshan> can i pm you
[00:18:03] <XXCoder> sure
[01:00:30] <Jymm> Man, that's MASSIVE... http://sat.wrh.noaa.gov/satellite/loopsat.php?wfo=mtr&area=west&type=ir&size=2
[01:20:28] <WalterN> yay for working 13.5 hours (so far)
[02:17:11] <Deejay> moin
[05:57:13] <jthornton> morning
[05:58:11] <jthornton> looks like moveoff is taking shape
[09:13:36] <Tom_itx> jthornton, nice to hear
[09:13:43] <Tom_itx> what have you done with it?
[09:19:45] <Tom_itx> if my machine were back together i would try that
[10:07:57] <PetefromTn_> Good Morning
[11:54:31] <pcw_home> big legos:
[11:54:33] <pcw_home> https://www.youtube.com/watch?v=LoRIztYmWjY
[11:55:33] <zeeshan> that is a very cool design
[11:55:42] <zeeshan> the power of the mechanical wedge always amazes me :D
[11:57:11] <zeeshan> ohj its not only a wedge
[11:57:16] <zeeshan> tehre is interlocking things
[11:57:52] <pcw_home> Yeah self aligning
[12:03:43] <ssi> cool
[12:05:47] <zeeshan> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xaf1/v/t1.0-9/422980_390031801075262_2029707621_n.jpg?oh=f349f1a9367502bb43fd5ac14f10b5c3&oe=551FA6D8&__gda__=1425741577_a6c756d7f2b4ff64716a1db09cf85d2d
[12:06:17] <ssi> hahaha
[12:06:28] <zeeshan> :D
[12:06:37] <zeeshan> did you heat treat?
[12:06:46] <ssi> yusss
[12:06:53] <zeeshan> howd it work out
[12:07:12] <ssi> perfectly :D
[12:07:19] <zeeshan> how much bigger did it grow/warp
[12:07:28] <ssi> pretty much immesurably
[12:07:28] <zeeshan> i havent used anything but a2
[12:07:33] <zeeshan> really?
[12:07:35] <ssi> yeah
[12:07:36] <zeeshan> from 1750F
[12:07:38] <zeeshan> to oil?
[12:07:42] <PetefromTn_> that is pretty cool
[12:07:43] <ssi> 1500F
[12:07:54] <ssi> I'm not happy with the first blocks I made, because of the millwork
[12:07:59] <ssi> I'm going to make a better set
[12:08:08] <ssi> but I finish ground one of them
[12:08:22] <ssi> and it's .5003" x 1.0002" x 1.9962"
[12:08:28] <ssi> it's short because I cut it short on the bandsaw :P
[12:08:48] <zeeshan> ill take it :)
[12:09:03] <ssi> parallelism is half tenth or better; I don't trust my shitty tenths indicators
[12:09:15] <ssi> metrology is part of this exercise too heh
[12:09:24] <ssi> I need to figure out how to measure squareness on the surface plate
[12:09:32] <ssi> forrest addy has a post about doing it with a 123 block and a height gage
[12:09:36] <ssi> but I need to internalize it
[12:09:54] <archivist> make a circular square
[12:10:04] <ssi> I'd like to have one
[12:10:09] <zeeshan> have you seen oxtoolco's youtube video?
[12:10:11] <zeeshan> on measuring squareness
[12:10:13] <ssi> no
[12:10:15] <zeeshan> he demonstrates it pretty good
[12:10:44] <zeeshan> https://www.youtube.com/watch?v=PDzL4Y0CIHM
[12:10:58] <zeeshan> start with square off
[12:11:02] <zeeshan> i think theres 3 parts.
[12:11:12] <ssi> cool thanks
[12:11:42] <ssi> I've been going nuts on ebay buying tooling
[12:11:53] <ssi> I lost some of my good metrology tools
[12:12:06] <ssi> actually found my good starrett and B&S tenths mics yesterday in a box of stuff from teh upstairs, and they're trashed
[12:12:23] <ssi> I had to buy a new set of gage blocks cause my set was by the laser; I used them for focal length touchoff
[12:12:37] <zeeshan> what ones did you buy
[12:12:49] <ssi> just the B grade shars ones
[12:12:51] <ssi> $80 81 piece set
[12:12:54] <ssi> same as I had before
[12:13:25] <zeeshan> you trust em? :p
[12:13:47] <ssi> I dunno! :)
[12:14:01] <ssi> they come with a test certificate with measured error
[12:14:09] <zeeshan> hehe
[12:14:14] <ssi> so if that's accurate it doesn't really matter to me how close to marked size they are
[12:14:52] <zeeshan> i have tested some fowler made in china ones
[12:14:55] <zeeshan> and phase 2
[12:15:05] <zeeshan> in comparison to a ceramic mitutoyo 1"
[12:15:12] <zeeshan> with a tenths indicator
[12:15:18] <zeeshan> they're definitely within a tenth!
[12:15:29] <ssi> yeah
[12:15:34] <zeeshan> dont know how square they are though
[12:15:54] <archivist> I did some testing here, it is not easy to get within tenths
[12:16:03] <zeeshan> why
[12:16:04] <ssi> no, it's definitely not easy
[12:16:47] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=comparator+mercer
[12:17:10] <archivist> I need to warm up the room before I play
[12:17:49] <archivist> it is a bugger to get the ball central
[12:17:52] <zeeshan> does that say
[12:17:54] <zeeshan> .00001
[12:17:56] <zeeshan> or .0001
[12:18:01] <zeeshan> for 1 div
[12:18:25] <archivist> 100000 th of an inch :)
[12:18:31] <zeeshan> hahah
[12:18:37] <ssi> that's awesome
[12:18:38] <archivist> nats cock or less
[12:18:47] <ssi> 10 uin
[12:19:14] <ssi> my hardinge's original control had a mode that made the minimum resolution 20uin, .00002
[12:19:14] <zeeshan> i bet if you hold that sphere with your hands
[12:19:18] <zeeshan> you can see the needle change =D
[12:19:49] <archivist> it shakes too much
[12:20:18] <archivist> I have a couple other toys which are optical
[12:21:50] <archivist> I was surprised how different all the "standards" were
[12:22:02] <ssi> yeah I'm sure
[12:22:07] <ssi> https://www.youtube.com/watch?v=3jGXsBNQBx0
[12:22:18] <ssi> that's how I was measuring the size and flatness of my block
[12:22:25] <ssi> it's stacked up with a 1" gage block
[12:22:40] <ssi> s/flatness/parallelism/
[12:23:14] <zeeshan> did you give up on your cnc conversion?!
[12:23:15] <zeeshan> :D
[12:23:21] <ssi> no
[12:23:24] <ssi> I just jump around a lot :)
[12:23:32] <ssi> I have to finish the interior of my cherokee too
[12:23:37] <zeeshan> i took a break from my sutff
[12:23:40] <zeeshan> was giving me stress
[12:23:41] <ssi> oh and I bought that pitts, and I need to build wings for it
[12:23:41] <ssi> heh
[12:23:41] <zeeshan> lol
[12:26:20] <ssi> I need to make some little parallel clamps like he's got
[12:26:36] <ssi> I'm looking for all those machinist school toolmaking projects to do
[12:26:41] <ssi> I'm having to teach myself all this crap :)
[12:27:25] <zeeshan> those parallel clamps are awesome
[12:27:28] <ssi> yeah
[12:27:28] <zeeshan> i dont have any :/
[12:27:33] <ssi> make some! :)
[12:27:39] <zeeshan> er
[12:27:41] <zeeshan> i have parallel clamps
[12:27:45] <zeeshan> i thought you were talking about parallel wedges
[12:27:53] <ssi> parallel wedges?
[12:28:02] <zeeshan> http://images.starrett.com/is/image/Starrett/154De50581cUSp1?wid=240&hei=240&qlt=80,1&fmt=png-alpha&maskUse=norm
[12:28:03] <zeeshan> those
[12:28:05] <zeeshan> for setup
[12:28:16] <ssi> oh yea adjustable parallels
[12:28:18] <ssi> I don't have any either
[12:28:33] <zeeshan> they look nice for setting up
[12:28:50] <ssi> I'm not sure what they'd be good for to be honest
[12:31:16] <ssi> so I'm watching this 'square off' video
[12:31:35] <ssi> and it occurs to me... both those 30 degree squares are measuring .0005" off across the face
[12:31:44] <ssi> maybe it's in his setup? his gage blocks are off or something?
[12:31:44] <ssi> heh
[12:31:52] <archivist> look at shaper tool http://www.micro-machine-shop.com/Starrett_995_%20Planer_Gage_5.jpg
[12:31:54] <zeeshan> well this guy who makes the suares
[12:32:01] <zeeshan> grinds em side by side in the fixture
[12:32:07] <zeeshan> so his fixutre could be off relative to the machine
[12:32:14] <ssi> yes definitely
[12:32:15] <archivist> tool pr0n http://www.micro-machine-shop.com/mensuration_instruments.htm
[12:32:23] <ssi> mestruation instruments?!
[12:32:44] <ssi> I like his height gage
[12:34:17] <ssi> I do like those little squares he's makin though
[12:34:28] <ssi> might be a fun project to add to my toolmaking list :D
[12:36:44] <ssi> ooh he's got the moore 123 blocks too
[12:36:45] <ssi> I like those
[12:38:31] <archivist> someone should train him not to put everything on one page
[12:39:08] <ssi> lol
[12:39:15] <ssi> I need to get some surface plate cleaner
[12:39:37] <archivist> some sandpaper ?
[13:02:23] <SpeedEvil> angle grinder
[13:02:26] <SpeedEvil> shines it rightup
[13:03:13] <archivist> mine did actually go rusty :(
[13:03:49] <roycroft> i use methyl alcohol to clean my surface plate
[13:04:24] <roycroft> or denatured ethyl alcohol, whatever is handy
[13:07:07] <SpeedEvil> archivist: electrolytic derusting is probably best
[13:12:42] <ssi> fortunately mine isn't going to rust
[13:17:21] <jdh> but rust never sleeps
[13:17:53] <ssi> rust also doesn't infect granite :P
[13:18:10] <jdh> don't let facts confuse the issue.
[13:21:01] <jdh> that's a pretty sexy page above.
[13:22:31] <archivist> he is rather good at taking pictures too
[13:25:46] <zeeshan> http://www.micro-machine-shop.com/digital_caliper_fractional_1.jpg
[13:25:47] <jdh> our gage lab through away 4 or 5 height gauges with granite plates a few months ago.
[13:25:48] <zeeshan> lol
[13:25:50] <zeeshan> that is pretty cool
[13:25:53] <zeeshan> the fractional mode
[13:26:05] <jdh> z: I have a HF one that does that.
[13:27:24] <archivist> I have a peg digital to 1/4" http://www.collection.archivist.info/searchv13.php?searchstr=caliper+vernier
[13:28:10] <jdh> that's kinda cool too
[13:28:44] <archivist> no idea what it was used for
[13:37:12] <PetefromTn_> Damn
[13:37:33] <PetefromTn_> looks like that .05" radius cutter I ordered won't get here til' monday
[13:37:37] <PetefromTn_> Oh well
[13:37:45] <ssi> aw
[13:38:16] <PetefromTn_> I can cut the rest of the parts in the machine mounted in my two vises and just wait until the cutter arrives to finish them
[13:38:48] <ssi> damn I'm hungry
[13:38:48] <PetefromTn_> already got it all programmed
[13:40:48] <PetefromTn_> still trying to decide on a base for the LED edge lit sign..
[13:44:18] <ssi> I'm gonna meander down to the shop shortly and setup the mill to make the next set of blocks
[13:44:35] <ssi> gonna actually tram the mill tightly this time :P
[15:03:46] <JT-Shop> it's a pain to tram a tilt and nod mill head
[15:05:14] <syyl_> thats what i think every time i see a bridgeport :D
[15:06:26] <JT-Shop> I mounted a dial indicator on mine to see if has moved
[15:06:49] <syyl_> oh, those go out of tram by itself?
[15:10:10] <JT-Shop> no, you have to screw up your G code usually... mine is a series 1 with a 3 axis Anilam conversion kit on it.
[15:32:01] <ssi> I just got it all trammed in tight :D
[15:32:20] <ssi> also, I bought a new set of harbor freight parallels because the set I bought when I first got the mill is missing one or two and some of them are nicked up
[15:32:32] <ssi> very good example of something from harbor freight worth buying, especially when you're new :)
[15:32:50] <ssi> so for funsies, I put the pair that I'm about to use on the surface plate, turns out they're dead nuts parallel and matched
[15:32:57] <jdh> one of the metal recycling places here opened a resale warehouse side. I can now get metal drops by the pound.
[15:32:59] <ssi> so I heartily support $30 HF parallels!
[15:34:01] <syyl_> parallels and screwless grinding vices are two things the chinese get right
[15:34:03] <syyl_> all the time
[15:34:18] <ssi> I have a few chinese grinding vises too
[15:34:25] <syyl_> i love mine
[15:34:26] <ssi> in fact I need to find my tiny one for doing these little blocks
[15:34:36] <ssi> I'm glad I bought all this crap years ago before I knew wtf to do with any of it :D
[15:34:38] <syyl_> have one with 25, 55 and 80mm
[15:34:42] <ssi> now that I'm figuring it all out, I have what I need
[15:35:47] <syyl_> and they all are dead nuts on
[15:35:55] <ssi> :D
[15:36:23] <roycroft> i need to weld some plate onto a square tubing frame i made
[15:36:38] <roycroft> it will be horizontal, so no tensile stress at all - just a tiny bit of shear stress
[15:36:44] <roycroft> i don't want weld beads around the edges
[15:37:06] <roycroft> i was thinking of drilling 1/8" holes through the plate and the top of the tubing, countersinking the holes in the plate, and just welding through the holes
[15:37:17] <roycroft> does that seem like a good plan?
[15:38:03] * roycroft knows there is some welding talent on this channel, and he is not part of that talent
[15:39:11] <ssi> lol
[15:39:22] <ssi> basically you'll be spot welding
[15:39:32] <roycroft> yes
[15:39:38] <ssi> sounds pretty reasonable, but I'm not a pro welder. I do know a pro welder, but he's at work at the moment
[15:39:46] <ssi> if you don't have an answer by the time he gets home I'll ask
[15:39:59] <roycroft> and i could do it neatly enough that there would be a minimum of grinding required
[15:40:20] <roycroft> i might not get to the welding until tomorrow
[15:40:41] <roycroft> i need to drill some holes in the plate, mount some brewing vessels, and then fill them with water to see if the frame sags
[15:40:55] <roycroft> i'd rather reinforce the frame before affixing the plate permanently
[15:41:27] <roycroft> if reinforcement is necessary
[15:41:38] <ssi> hm my phone won't get on wifi
[15:41:47] <ssi> I took a video of inspecting these parallels and I want to post it
[15:41:55] <roycroft> are they parallel?
[15:42:00] <ssi> very
[15:42:05] <roycroft> that is good
[15:42:22] <roycroft> otherwise they would be fraudulent
[15:42:33] <ssi> well they came from harbor freight
[15:42:38] <ssi> so you can imagine why I decided to inspect :)
[15:42:44] <roycroft> yes
[15:42:51] <roycroft> wow
[15:42:53] <roycroft> 15 degrees out
[15:43:01] <roycroft> no wonder i have to work on a tee shirt today
[15:43:08] <roycroft> it got too hot with a heavy flannel shirt on
[15:43:20] * roycroft likes balmy december days
[15:43:39] <ssi> I hope that's in french units :P
[15:43:57] <ssi> if so, it's a bit warmer than that here
[15:44:04] <ssi> maybe 16 french fake temperature units or so
[15:44:59] <roycroft> it's normal units, not those crazy f things that the us still clings to
[15:45:12] <ssi> :)
[15:45:23] * roycroft heads back to the shop for a bit
[15:52:03] <zeeshan> Hm..
[15:52:07] <zeeshan> 3 wires coming from the lamp
[15:52:12] <zeeshan> 220v lamp?!?
[15:52:23] <zeeshan> er
[15:52:23] <zeeshan> duhh
[15:52:31] <zeeshan> nm
[15:52:38] <zeeshan> 1 hot 1 neutral one earth
[15:53:10] <marmite> of course
[16:07:04] <pcw_home> ahh cmon try it on 220, it will light up your life...
[16:25:53] <ssi> https://www.youtube.com/watch?v=V0Q67PW1kMk
[16:26:06] <ssi> got my parallel inpsection vid up at long last
[16:26:14] <ssi> stupid phone refused to do hd tho :P
[16:33:33] <Deejay> gn
[16:46:00] <zeeshan> is that a tenths indicator
[16:46:17] <zeeshan> fuu
[16:46:25] <zeeshan> indicator isnt touching!
[16:46:26] <zeeshan> :P
[16:51:14] <pfred1> sweet I'm right where I thought I'd be 4 days ago now!
[16:52:32] <pfred1> zeeshan I rebuilt a wheel dresser once and when I indicated it the tenths gauge didn't even budge
[16:52:50] <pfred1> I thought something was wrong myself so I called someone else over to have them check it out
[17:06:05] <ssi> zeeshan: it's defniitely touching
[17:06:11] <zeeshan> :-)
[17:06:16] <zeeshan> i dont see proof in video!
[17:06:18] <ssi> :)
[17:06:21] <ssi> yeah SORRY
[17:06:23] <ssi> but I promise it is
[17:06:24] <zeeshan> =]
[17:06:37] <zeeshan> is that a tenths indicator?
[17:06:39] <ssi> I'm milling up my .5-1-1.5 blocks now
[17:06:40] <ssi> yeah it is
[17:06:44] <zeeshan> nicee
[17:06:52] <ssi> on the 1" dimension off the mill I have .0003" parallelism across 1.5"
[17:07:01] <ssi> I'm just doing .010" oversize in all dimensions this time
[17:07:07] <ssi> cause it didn't move much at all last time
[17:08:20] <zeeshan> lol im looking at a differential rebuild service manual written in 92 for the rx7
[17:08:31] <zeeshan> "coat the ring gear with red lead"
[17:08:33] <zeeshan> :-)
[17:08:48] <ssi> heheh
[17:17:36] <pfred1> red lead is glazing putty
[17:17:59] <pfred1> well in one context at least
[17:18:28] <pfred1> comes in green too
[17:23:28] <zeeshan> lol
[17:23:31] <zeeshan> f that nonsense :P
[17:41:32] <ssi> heheh
[17:46:55] <pfred1> zeeshan they're probably explaining how to gauge contact
[18:06:26] <zeeshan> pfred1: i know that :P
[18:06:34] <zeeshan> im just suprised at the lead paint suggestion
[18:06:53] <zeeshan> im sure they make an alternative
[18:07:04] <zeeshan> i wonder if i can just use dykem
[18:07:13] <zeeshan> or if its too thin.
[18:28:17] <pfred1> zeeshan red lead contains no lead
[18:28:26] <zeeshan> link
[18:28:33] <pfred1> it replaces what they used to use lead for
[18:29:27] <pfred1> before plastic fillers they used to paddle molten lead onto auto body panels
[18:29:44] <SpeedEvil> it has advantages over plastic body fillers
[18:29:54] <SpeedEvil> but needs lots more skill
[18:29:54] <pfred1> yeah lead doesn't shrink
[18:30:13] <pfred1> my car was leaded
[18:30:34] <pfred1> there's no seam on the front fenders
[18:30:41] <pfred1> the factory leaded them on
[18:30:58] <pfred1> its a 1966
[18:32:35] <pfred1> zeeshan so now you know why red lead is called lead it is not because it contains lead, but because it replaces lead
[18:32:43] <zeeshan> o
[18:32:43] <zeeshan> :)
[18:33:04] <pfred1> I think evne the green stuff is called red lead or glaze
[18:33:26] <pfred1> that's what i call it glazing putty
[18:35:32] <pfred1> where's the fender stop? http://static.cargurus.com/images/site/2010/04/13/19/44/1971_volvo_p1800-pic-6455451537908584482.jpeg
[18:35:39] <pfred1> that isn't my car but same model
[18:36:21] <pfred1> one time I was glad I have a set of 24SP vise grips
[18:36:41] <pfred1> I used it to tack weld the fender
[18:56:15] <Aero-Tec> i NEED TO SEE THE VALUE OF A VARIABLE
[18:56:22] <Aero-Tec> oops
[18:56:39] <Aero-Tec> how do I print to screen info?
[19:02:32] <Aero-Tec> found it
[19:05:30] <Jymm> woohoo found more clips =)
[19:14:19] <Jymm> As much as I hate UPS, this is just so fucking cool... https://www.youtube.com/watch?v=0IsL5AMqLMY
[19:25:58] <ssi> my new .5-1-1.5 blocks are in the oven now :D
[19:26:03] <ssi> they came out pretty good!
[19:26:14] <ssi> there's some aesthetic things that could be better, but overall I'm pleased
[19:26:24] <ssi> assuming I can nail the finish grinding, I'll have something to be proud of
[19:26:48] <jdh> plain blocks, or holes and thread?
[19:27:11] <ssi> they have 2 3/8-16 holes in them
[19:27:17] <ssi> same as typical 123 blocks
[19:27:21] <jdh> cool
[19:27:34] <jdh> as an apprentice (to yourself) aren't you supposed to make those by hand?
[19:27:42] <ssi> define by hand?
[19:27:53] <jdh> hand tools
[19:28:32] <ssi> I'm not interested in making precision tools with a hacksaw, file, and oilstone
[19:29:06] <ssi> cast iron blocks can be hand-scraped, which is something I'd be willing to try
[19:29:18] <ssi> forrest addy does a class where you do that
[19:29:34] <ssi> but these are tool steel, not cast iron
[19:32:34] <pfred1> http://www.amazon.com/gp/product/B00BGBOJZO/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1944687682&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B00092CJC6&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=05ATZWWHZYSFTQ1832JF
[19:32:49] <pfred1> Anytime Tools 1-2-3 Blocks Matched Pair $15.95
[19:37:48] <ssi> gosh I had no idea you could simply purchase them
[19:37:52] <ssi> what have I been doing with my life
[19:38:43] <mozmck> not building your airplane :)
[19:38:50] <ssi> yeah yeah
[19:39:01] <mozmck> how's it going anyhow?
[19:39:08] <ssi> I bought another airplane that I have to finish first :)
[19:39:17] <mozmck> haha!
[19:39:20] <mozmck> what kind?
[19:39:25] <ssi> a pitts S1-SS
[19:39:32] <mozmck> oooh!
[19:39:41] <ssi> need to build a set of wings for it
[19:39:47] <ssi> probably start on them next weekend
[19:40:10] <mozmck> metal wings I suppose?
[19:40:15] <ssi> wood and fabric
[19:40:22] <mozmck> Neat!
[19:40:23] <ssi> the fuselage is welded 4130 tube and fabric
[19:40:31] <mozmck> That's what I plan to build if I get time.
[19:40:35] <ssi> it's a complete flying airplane minus the wings
[19:40:38] <ssi> and wings'll be easy
[19:41:01] <mozmck> Yes, shouldn't be hard. Solid spars?
[19:41:15] <ssi> yeah solid spruce
[19:41:24] <ssi> they're like 3/4 x 4" spars
[19:41:35] <mozmck> I've thought of making built up or box spars.
[19:41:37] <ssi> laminated spars are super strong but it's not worth the effort
[19:41:46] <ssi> with solid spars it's a 12G airplane
[19:42:08] <mozmck> The plane I have had solid spars - something like 3/4" by 5" or so
[19:42:18] <ssi> remind me what you have?
[19:42:58] <mozmck> It was a funk
[19:43:10] <ssi> ah nice
[19:43:25] <mozmck> I have most of the parts, but no engine.
[19:43:51] <mozmck> I'd like to use only the main frame and build a homebuilt to almost the same pattern, but it would be a homebuilt
[19:44:00] <ssi> easy enough
[19:44:13] <mozmck> I have a couple of corvair cores for a potential engine
[19:44:47] <mozmck> should be, just need time! Just had our third child, 3 under 3 right now.
[19:47:08] <ssi> yikes
[19:47:12] <ssi> that's definitely an impediment
[19:47:22] <ssi> ok blocks are hardened
[19:47:32] <ssi> waiting for the furnace to cool then I'll try to draw them to 62HRC or so
[19:47:45] <ssi> it'll be a bit difficult cause that's like 300F and this furnace doesn't like to run that cool
[19:47:49] <ssi> might be better off in a toaster oven
[20:08:23] <ssi> https://pbs.twimg.com/media/B4N4aVHIgAA11X2.jpg:large
[20:08:34] <ssi> the slots came out ugly, and a couple of the countersinks aren't centered
[20:08:52] <ssi> and my hand-cut chamfers don't look good at that level of magnificatin either :P
[20:10:45] <pfred1> countersinking is tricky on a press
[20:11:23] <pfred1> I always have to slam it to center it then cut it
[20:11:37] <pfred1> easier with a hand drill
[20:12:57] <roycroft> i have some countersinks with pilots
[20:13:03] <roycroft> for the hole sizes they fit they work really well
[20:13:29] <pfred1> I just have the cones
[20:17:09] <pfred1> shop I worked in should have had countersinks with pilots I only remember ever countersinking this one part we made there
[20:17:16] <roycroft> mine are like this:
[20:17:18] <roycroft> http://toolinghouse.com/images/products/thumb/5piececoundeburrpilot.gif
[20:17:28] <roycroft> they're the best countersink tools i've ever used
[20:17:40] <roycroft> virtually chatterless
[20:18:07] <pfred1> at home now I just use a hand drill I get good countersinks doing that
[20:18:57] <roycroft> i got some aircraft countersinks off ebay a while back
[20:19:12] <roycroft> they're awesome, because they have a depth stop that can be adjusted very accurately
[20:19:43] <pfred1> I only countersink holes I'm going to tap makes the tap start easier
[20:19:51] <roycroft> they are also piloted
[20:20:12] <roycroft> i countersink almost every hole a little bit
[20:20:21] <roycroft> to debur and make sure the surface is flush
[20:20:56] <roycroft> but most holes i just touch with the countersink
[20:20:58] <pfred1> if it is just a clearance hole for a bolt I don't worry about it
[20:21:21] <roycroft> well you don't want a wire edge on it preventing you from bolting it flush
[20:22:00] <roycroft> for that kind of work i usually just use a battery drill with a countersink in it
[20:22:13] <roycroft> so i don't have to swap tooling to touch the hole with the countersink
[20:22:40] <pfred1> yeah I use a cordless
[20:23:53] <pfred1> I finally have all of my brackets cut
[20:24:02] <pfred1> what a pain that ended up being
[20:25:21] <LatheBuilder> Hello!
[20:25:25] <pfred1> on the front of my machine because of where the bearing supports are I have to use 2 brackets a corner
[20:25:44] <pfred1> then to make matters worse those corners are not really square
[20:26:17] <pfred1> so I ended up milling each angle at a bit of an angle
[20:26:35] <pfred1> so they fit in the corners tight
[20:26:43] <LatheBuilder> my retrofit is alive and nearly tuned. I crashed pncconf changing the pulsecounts within the open loop utility.
[20:28:23] <LatheBuilder> now the open loop drive enable does not function. anyone know how to restore it? tried upgrading to the master release, no luck.
[20:29:05] <pfred1> I use software stepping so I don't even know what you're talking about
[20:30:34] <LatheBuilder> no worries friend, thanks for the reply
[20:30:48] <LatheBuilder> what are you building?
[20:31:37] <LatheBuilder> pfred1 >> a router perhaps?
[20:32:01] <pfred1> that's what I'm trying to make yeah
[20:32:13] <pfred1> first two tries were meh
[20:32:26] <LatheBuilder> nema 23 steppers?
[20:32:28] * pfred1 is hoping that the third time is a charm though
[20:32:32] <pfred1> yeah
[20:32:57] <pfred1> each axis is different though
[20:33:19] <pfred1> X has dual twin stacks Y is twin singles and Z is a single twin
[20:33:25] <LatheBuilder> dremel type spindle?
[20:33:33] <pfred1> a Bosch Colt
[20:34:02] <pfred1> dremels are kind of cheeze whiz
[20:34:48] <LatheBuilder> i hear you there. the Colt's nice for panelcutting. make a good high speed spindle
[20:35:08] <pfred1> I got it at a flea market for $15 so I figured what the hey
[20:35:45] <pfred1> it looks like it'll do what I'm looking to do
[20:35:52] <LatheBuilder> nice find
[20:36:16] <LatheBuilder> build coming along to your liking?
[20:36:42] <pfred1> well like i said so far I've run my machine in two different configurations and so far I've run into problems
[20:36:53] <pfred1> so each time I beef it up some more
[20:36:55] <LatheBuilder> ya?
[20:37:01] <LatheBuilder> stiffness related?
[20:37:14] <pfred1> yeah the first time I really tried to cheap out and I just ran skate bearings right on wood
[20:37:23] <pfred1> that worked pretty good in retrospect
[20:37:39] <pfred1> because the bearings would dig into the wood and sort of make grooves for themselves
[20:38:01] <pfred1> but it was sloppy and i figured I'd constantly have problems so I put steel angle where the bearings ran
[20:38:20] <pfred1> then i ran into some serious alignment issues because now the bearings were on the steel
[20:38:49] <pfred1> the whole X axis frame wasn't stiff enough so when the machine stalled the while thing bent into a diamond shape
[20:39:04] <pfred1> now I have realigned the X axis rails better and I am reinforcing the corners
[20:40:16] <LatheBuilder> project just for fun or do you have things you need to build with it?
[20:40:24] <pfred1> yeah just for fun
[20:40:29] <pfred1> I like electronics and Linux
[20:40:42] <pfred1> all of my electronics work great
[20:40:51] <LatheBuilder> cool
[20:41:05] <pfred1> LInux works too just the frame of the machine has been a bit difficult to dial in so far
[20:41:39] <pfred1> yeah I made all of my own motor drives and my break out board too
[20:41:52] <pfred1> 5 motor drives
[20:42:05] <pfred1> 3 bipolar and 2 unipolar
[20:43:28] <pfred1> when i saw the X axis twist like it did I thought maybe the drives work too good?
[20:44:11] <pfred1> they're a lot more powerful than I imagined they'd be
[20:45:44] <LatheBuilder> ya, nema 23's are surprising for their size.
[20:46:10] <pfred1> nah my X axis motors are junk they are these sur[plus things i bought on the net for like $13 a piece
[20:46:24] <pfred1> supposedly they are 200 oz/in
[20:46:42] <pfred1> they are ling something or other brand?
[20:46:51] <LatheBuilder> hard to beat for the cost within their limits
[20:47:05] <LatheBuilder> lin engineering? they make good motors
[20:47:11] <pfred1> maybe lin
[20:47:36] <pfred1> yeah I wish I'd bought more when I saw them
[20:47:44] <pfred1> because now I'm wondering if one isn't messed up
[20:47:58] <pfred1> and I'll have to repalce them both if one is I want a matched pair
[20:48:42] <LatheBuilder> drives make a big difference too. also, current limits on your power supply
[20:48:44] <pfred1> I was rolling the lead screw attached to one motor with the lead nut disengaged and there was one funny spot I felt
[20:49:05] <pfred1> but it was still hooked to the drive so something might have been going on there too I'm not sure
[20:49:25] <pfred1> not that the drive was powered or anything
[20:49:37] <LatheBuilder> only one place on the screw, or repeats every revolution of the motor?
[20:49:59] <pfred1> yeah screw was off the nut but the lead was attached to the shaft
[20:50:12] <pfred1> was one spot in the revolution
[20:50:28] <pfred1> it is the side that stalled too
[20:51:06] <pfred1> I'm not sure now but it has me a bit concerned until I check it out more
[20:52:01] <pfred1> night just be a misalignment between the motor and the lead too
[20:52:13] <pfred1> I mean I'm only using rubber hose connectors
[20:52:21] <pfred1> this is a real cheap build
[20:52:46] <Jymm> This is now my standing Christmas list till the day I die... http://www.aol.com/article/2014/10/31/flying-cars-are-no-longer-science-fiction/20986888/
[21:00:21] <LatheBuilder> Jymm Want one too but I think the upkeep would kill me.
[21:01:04] <Jymm> LatheBuilder: Nah, get two, use one for parts =)
[21:01:14] <LatheBuilder> pfred1 if you loosen it does it still bind
[21:01:46] <pfred1> LatheBuilder I don't know yet I have not run it since I've been working on it
[21:02:37] <LatheBuilder> Jymm >> it would be really cool to live out in the country and take off on a strip in the back yard
[21:02:51] <pfred1> lots of folks by me have air strips
[21:03:03] <pfred1> there's a whole neighborhood around an air strip by me
[21:03:11] <pfred1> people have hangers for garages
[21:03:31] <LatheBuilder> good fun.
[21:03:32] <pfred1> let me find it on google maps
[21:04:44] <LatheBuilder> pfred1 >> if you move it to the high point of binding and loosen the coupler momentarily
[21:06:24] <LatheBuilder> if it gets better, great. if not could be bad bearings in the motor though that's rare without unusually harsh treatment like a crash big enough to bend whatever it drove last.
[21:06:58] <pfred1> LatheBuilder that is what i am worried about I might have messed it up when it stalled
[21:07:38] <pfred1> this might be the road where they're all mext to an air strip http://goo.gl/maps/JDL5c
[21:07:45] <pfred1> I haven't been by there in a while now
[21:08:49] <pfred1> right out the back yard then up in the air
[21:12:10] <LatheBuilder> would be nice...
[21:12:49] <LatheBuilder> i am pretty content being unimportant enough to not need constant travel. =)
[21:13:08] <pfred1> people barn storm here
[21:13:19] <pfred1> they don't actually fly anyplace they just go up and fly around
[21:13:58] <pfred1> I've seen folks do it
[21:14:04] <pfred1> they like do circles in field
[21:15:24] <LatheBuilder> neat. there are a number of ultralight pilots near me that do the same thing
[21:15:39] <pfred1> yeah they have like acrobatic planes I guess
[21:16:01] <pfred1> i guess when you get bored windsurfing
[21:16:23] <pfred1> because lots of folks do that here too
[21:16:26] <mozmck> I still want to build an ultralight.
[21:16:40] <pfred1> there are heavier but they are small planes
[21:16:46] <roycroft> all you need to do that is a piece of paper, mozmck
[21:16:56] <roycroft> just fold it up and throw it
[21:17:12] <pfred1> seen the guy with the paper airplane gun?
[21:17:15] <mozmck> I live in the country, and neighbors all around have their own airstrips
[21:17:38] <ssi> well that *almost* worked out :D
[21:17:54] <pfred1> https://www.youtube.com/watch?v=J7K91g8yG_w
[21:17:55] <LatheBuilder> pfred1 >> ya, that's some dedication to building.
[21:18:24] <pfred1> that is hilarious
[21:18:36] <mozmck> Legal Eagle is the kind of ultralight I'm interested in.
[21:18:59] <pfred1> we started pumpkin chunkin here too
[21:19:09] <pfred1> that started like 2 fields east of me
[21:19:32] <pfred1> so about 2 miles away
[21:20:00] <pfred1> though by the time I'd moved here they'd moved it across town
[21:20:12] <pfred1> so about 20 miles away
[21:20:46] <pfred1> I think chunkin is over now though
[21:21:03] <pfred1> some redneck got the bright idea to sue the organizers
[21:21:35] <pfred1> he was one of the spotters on a quad and he flipped over
