01:06 AM Deejay: moin
02:41 AM veegee: totally random: any recommendations for brake pads for my Jeep JK?
02:41 AM veegee: Need to replace the rear brake pads and likely rotors
02:41 AM veegee: I went with cheap crap last time and the braking power is terrible
02:43 AM veegee: Also totally random: went to a leather craft store to get some leather scraps to make way wipers for my vertical mill
02:44 AM veegee: The employee actually knew what a vertical mill was and what way wipers are for and pointed me to the perfect type of leather. Did not expect that
03:02 AM Wolfmetalfab is now known as Wolf__
05:00 AM JT-Cave: morning
06:40 AM Tom_L: morning
06:53 AM Tom_L: warming back up again
06:53 AM Tom_L: 75F now / 95 high
10:15 AM _unreal_: its likely 95 rigtht now here
10:15 AM _unreal_: hehe
10:20 AM Tom_L: humidity or temp?
10:20 AM Tom_L: :)
10:23 AM skunkworks: it is super humid here
10:23 AM skunkworks: or as my daughter used to say.. Human.
10:24 AM Tom_L: hah
10:24 AM Tom_L: they're cute then. too bad they grow up and take the car from ya
10:35 AM _unreal_: speaking of I'm getting my daughter today
10:35 AM _unreal_: god I'm dieing to get out of this @#$@#$@3 house
10:35 AM _unreal_: as in move
10:36 AM _unreal_: found a home I really really want to buy but suprise suprise no cash
11:06 AM jymmmm: good morning
11:07 AM _unreal_: afternoon
11:12 AM skunkworks: morning
11:46 AM Deejay: re
12:33 PM _unreal_: just ordered a package of these https://www.amazon.com/Transparent-Intensity-Lighting-Electronics-Components/dp/B01AUI4VRE/ref=sr_1_3?dchild=1&keywords=white%2BLED%2Bdiode&qid=1596993832&refinements=p_85%3A2470955011&rnid=2470954011&rps=1&sr=8-3&th=1
12:33 PM _unreal_: this dust shoe I'm going to have INTERNAL light
12:33 PM _unreal_: ve7it, I'm getting my daughter tonight.... I can finally relax... and may go back to fighting with the motor controllers.
12:33 PM _unreal_: when I do I am just going to remove all of them and then start putting them in one at a time
12:34 PM _unreal_: so I can ensure there are no shorts......
12:53 PM ve7it: _unreal_, cool... sounds like you got your spindle issue resolved.... funny they got the bearing so screwed up.. hopefully no flat spots, but at least you know how to replace it if needed
01:55 PM _unreal_: issue with the bearing
01:55 PM _unreal_: ya I think it was likely caulked
01:55 PM _unreal_: and possible particals inside the bearing
01:56 PM _unreal_: but more so I think it was caulked and causing excess force
01:56 PM _unreal_: the same bearing is running very cool now
01:56 PM _unreal_: and there does not seem to be any new play
03:15 PM Deejay: gn8
03:26 PM _unreal_: just amazing, I'm blasting .5" PVC faom board at 200mm/min .5 plunge and my mill is taking it like a champ
03:26 PM _unreal_: what a difference
03:26 PM jymmmm: Eeeeesh, took forever to get my Craftsman 13/16" spark plug socket from lowes, almost a month and two orders
03:27 PM _unreal_: came from china likely
03:32 PM jymmmm: Whoa... "Craftsman is a registered trademark of Stanley Black and Decker Inc"
03:34 PM Rab: In March 2017, Stanley Black & Decker acquired the Craftsman brand from Sears Holdings, which retained a limited license for Craftsman products.
03:36 PM _unreal_: ya sears was dieing
03:36 PM jymmmm: I always thought that craftsman was a seperate entitiy which I guess it is
03:36 PM Rab: It's a brand, that Sears sold.
03:37 PM jymmmm: The NEW craftsman part numbers are now prefixed with "CMMT"
03:38 PM Tom_L: jymmmm, you could have borrowed mine
03:38 PM jymmmm: ad this socket does say mande in taiwan
03:38 PM jymmmm: Tom_L: 13/16?
03:38 PM Tom_L: mine is the real deal though sorry if you expected chinese
03:38 PM Rab: Sears has a royalty-free license to the Craftsman brand, and royalties on Craftsman tools sold, for 15 years after the sale. Afterwards, they will pay a 3% licensing fee.
03:38 PM Tom_L: jymmmm, yes i have 3 sizes
03:39 PM Rab: I'll be impressed if they're still around to pay a 3% fee in 2032.
03:39 PM Tom_L: and maybe 2 of those
03:39 PM Tom_L: one on a wobble socket
03:40 PM jymmmm: IT's just for the generator. The gen came with one of those cheapy socket things, but it was so cheap that it just jammed on the plug
03:40 PM Rab: I saw Craftsman tools in Lowe's, but I didn't think too hard about it.
03:40 PM Tom_L: jymmmm, was it really supposed to work?
03:40 PM jymmmm: Rab: OSH sold craftsman, lowes bought OSH
03:40 PM Tom_L: Rab, lowes, ACE and who knows where else
03:41 PM jymmmm: Tom_L: Sure, once a year or so
04:01 PM flyback: have you guys seen gear show
04:01 PM flyback: he rebuilds a lot of abandoned cordless tools
04:01 PM flyback: converts them to lion etc
04:01 PM flyback: thwe sawzaw rebuild was insane
04:01 PM flyback: so many pieces
04:35 PM skunkworks: these import timing pullys don't have any references on them.. shocker.
04:36 PM skunkworks: have to make sure I indicate to the actual gear teeth
04:45 PM Tom_L: skunkworks, where did you get them and what series?
04:45 PM Tom_L: i've been looking at a few for my new spindle motor
04:45 PM Tom_L: when i get it
04:49 PM Tom_L: i've been looking at sdp-si but also some of the ali shops
04:49 PM Tom_L: i'm gonna need something heavier than GT2 but i'm not sure i need xl
05:27 PM Thorhian: My new AC servo should be coming tomorrow :D
06:00 PM andypugh: I found a new use for the Deckel-clone tool and cutter grinder.
06:01 PM XXCoder: tool grinding? heh
06:01 PM andypugh: The throttle bodies on my bike clamp to the head with rubber tubes and (effectively) hose clamps. And you need a very, very, long 4mm hex key to tighten and loosen them.
06:02 PM andypugh: I have had a ver, very long flat-blade screwdriver for more than 25 years and never used it. So today it got re-ground into a hex key
06:04 PM XXCoder: nice
06:05 PM andypugh: I have previously used several bits of 1/4” drive socketry, but you have to squeeze it past cooling pipes heat shield and loom through the 12mm gap between the frame and the cam cover. So there is a strong tendency to leave parts behind. After having to take the throttle bodies back out again to recover a bit, I decided the time had come for the screwdriver to sacrifice itself.
06:06 PM XXCoder: 25 years of lazyness, time for it to work
06:06 PM XXCoder: yiu can buy another if you suddenly need one anyway
06:08 PM andypugh: I wasn’t sure I would use the grinder when I got it, but it has made a quantum leap in what I can now make.
06:08 PM jymmmm: andypugh: woohoo
06:08 PM andypugh: The screwdriver regrind was literally a 5 minute job.
06:12 PM andypugh: This is another thing that I would have had no way to make previously: https://photos.app.goo.gl/ywRiuKYpXp4XSJq18 It’s a solid carbide boring bar for threading an non-standard Acme nut.
06:13 PM XXCoder: looks decent
06:19 PM andypugh: The chinese clones are possibly more developed than the 1950s originals: https://www.ebay.co.uk/itm/293602362314 but I like my old iron so bought an old one: https://www.ebay.co.uk/itm/124286748370 The old ones have quirks like partial angular scales, rather than full circles, limited swivel motion and they are not cut away under the cross bar so the handles clash. Basically the old ones are better made and the new
06:19 PM andypugh: are better designed….
06:25 PM flyback: andypugh, YOU GO TO HELL
06:25 PM flyback: andypugh, YOU GO TO HELL AND YO DIE!......................................................................................................................................GRINDER!
06:25 PM * flyback ducks
06:30 PM roycroft: i should go work on my eccentric drifts while waiting for glue to dry
06:40 PM XXCoder: "After many years of using a staircase spindle I finally got around to making a nice rammer." LOL i always thought that thing was table leg
06:41 PM XXCoder: (myfordboy)
06:46 PM {HD}: does linuxcnc have any support for 100w chinese laser cutters?
06:47 PM XXCoder: likely after you rip out controller but directly supported as is not sure
06:50 PM {HD}: the one I am looking at has the “ruida” controller.
06:50 PM {HD}: I don’t really want to rip it apart so maybe I will just try it with the native controller and the recommended software.
06:52 PM XXCoder: might have answers https://forum.linuxcnc.org/plasma-laser/33058-laser-raster-engraving
06:52 PM XXCoder: 2017 pretty old some info may have channged since
07:10 PM {HD}: neat. I don’t plan on much engraving(raster) mostly just cutting.
07:15 PM XXCoder: yeah but then its about linuxcnc with same machine you has
07:18 PM _unreal_: so finally got my daughter back
07:18 PM _unreal_: just got home
07:19 PM _unreal_: oh discovered what was so @#$@# up with my cnc/pc yesterday, my error but stupid ass BACKWARDS thinking EURO produced cam software I paid for was messing me up.
07:20 PM _unreal_: btw the stuffness of the machine is amazing now
07:20 PM _unreal_: compaired to what it was
07:29 PM flyback is now known as phlyback
07:29 PM phlyback is now known as flyback
07:30 PM flyback is now known as phlyback
07:33 PM phlyback is now known as flyback
07:46 PM _unreal_: its just amazing this new spindle is stone cold under heavy load
07:46 PM _unreal_: I love it
07:47 PM andypugh: {HD}: Mesa recently added a galvanometer control module to Hostmot2. I am not sure if that it relevant to your question
08:02 PM XXCoder: MESA isnt too expensive if its to be production machine
08:02 PM XXCoder: returns would easily cover it
08:54 PM _unreal_: omg my machine is working so much better
08:54 PM _unreal_: LOVE IT
08:54 PM _unreal_: one side note
08:54 PM _unreal_: DUHHHHHHHH just built the foot for my new dust shoe. forgot to subtract for the bristle material, looks like I got some sanding to do
09:09 PM Tom_L: jymmmm,
09:09 PM jymmmm: Tom_L:
09:09 PM jymmmm: Tom_L: MOM????????????????????????
09:12 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/Broach/sockets.jpg
09:12 PM Tom_L: bring it by once a year....
09:18 PM Tom_L: jymmmm,
09:18 PM Tom_L: go back to sleep now.
09:19 PM jymmmm: Tom_L: lol, well, no need NOWWWWWW
09:22 PM _unreal_: ok minus the front window and magnets I now have most of a dust shoe :)
09:23 PM Tom_L: why did you break your front window?
09:23 PM Tom_L: why did you throw the magnets thru your front window?
09:25 PM _unreal_: ?
09:25 PM _unreal_: I use clear poly as a window on my dust shoes so I can see what is going on
09:26 PM _unreal_: o,O
09:26 PM Tom_L: yeah, i'm just tired and having fun
09:26 PM _unreal_: and magnets to help hold the remove able part of the show
09:26 PM _unreal_: I'm doing a new setup with this one. this time I'm going to build a custom retainer peg... with springs and stuff
09:27 PM _unreal_: so when I put the bottom part on I push down the pegs and rotate them 90 degree's and release to clock in the shoe
09:27 PM _unreal_: one on each side
09:27 PM _unreal_: should be amazing
09:27 PM _unreal_: no more elastics
09:28 PM _unreal_: both shoes are close in size but this one is going to have a much bigger window
09:29 PM _unreal_: SOOOOOOO amazing to be able to mill aluminum so easy now
09:30 PM Tom_L: yep
09:30 PM Tom_L: i was surprised how well mine did on steel even with the crap motor
09:30 PM _unreal_: I've never tried steel
09:30 PM _unreal_: then again I cant do low RPM
09:31 PM _unreal_: aand that new spidnle has great speed control its not designed for low RPM
09:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Strap_clamp.jpg
09:32 PM _unreal_: ? interesting?
09:32 PM XXCoder: grinded?
09:32 PM Tom_L: no cut on the mill
09:32 PM XXCoder: or did you mean mill a slot
09:32 PM Tom_L: yeah i made a few of those strap clamps
09:32 PM XXCoder: well not bad
09:32 PM Tom_L: 5/16 steel
09:32 PM XXCoder: expecially if crap motor
09:33 PM Tom_L: took it slow
09:33 PM XXCoder: bit of layers and slight chatter
09:33 PM _unreal_: https://cdn.discordapp.com/attachments/717411349541683212/738917731151118376/15962420896107010412417595846703.jpg my origninal mill made its upgrades :)
09:33 PM XXCoder: maybe sgould do finishing pass if you care about that
09:33 PM Tom_L: not for me
09:33 PM Tom_L: just a tool to an end result
09:33 PM _unreal_: not sure what kind of a bit I would need to do steel
09:33 PM XXCoder: cool
09:34 PM _unreal_: and regardless I'd have to cut at high rpm
09:34 PM Tom_L: _unreal_, you would burn the bit up
09:34 PM _unreal_: ya I figured
09:34 PM _unreal_: and no cooling ether
09:34 PM _unreal_: so I'm stuck to aluminum and soft materials
09:34 PM Tom_L: brass is fun to work with
09:35 PM _unreal_: yall hear about simon cowel?
09:35 PM Tom_L: it grabs a little but it cuts nice
09:35 PM _unreal_: he's FUCKED for life after today
09:36 PM Tom_L: stick to trikes
09:47 PM _unreal_: hum
09:48 PM infornography: yeet
09:49 PM _unreal_: what the yeet you talking about boy
09:51 PM infornography: the boog
09:54 PM XXCoder: you the member of boogoloo dimwit group?
09:55 PM infornography: what group is that?
09:55 PM XXCoder: oh people who wants civil war to happen now
09:55 PM infornography: I'm pretty sure I'm opposite of that group then
09:56 PM XXCoder: yeah was kidding, i know youre not a moron
09:57 PM infornography: 2020 is madness
09:57 PM Tom_L: 2020 is a reality check
09:58 PM roycroft: it's been a year, that's for sure
09:58 PM XXCoder: yeah
10:04 PM roycroft: i've been focused on long-term goals/projects for a long time, but the way things are these days, that's just silly
10:04 PM roycroft: so i've been going day by day for months
10:05 PM roycroft: and in a way that's actually been good - i've actually been getting a lot of stuff done that i otherwise wouldn't have
10:06 PM roycroft: of course, this workbench project is getting in the way of everything else right now, and will continue to do so for quite a while
10:07 PM roycroft: it's really coming along, though
10:21 PM _unreal_: tomorrow I'm getting magnets
10:21 PM _unreal_: cant wait
10:21 PM JavaBean: making a wind turbine?
10:21 PM _unreal_: no new dust shoe for thenew spindle/z setup
10:21 PM JavaBean: meh, sounds boreing
10:22 PM _unreal_: very
10:22 PM _unreal_: and messy right now
10:22 PM _unreal_: new spindle SOOO much better
10:22 PM _unreal_: and new Z
10:22 PM _unreal_: sooo rigid
10:24 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200809_201340.jpg
10:24 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200809_201356.jpg
10:29 PM skunkworks: Tom_L: have to cut a blind keyway...
10:31 PM Tom_L: skunkworks, are those xl series?
10:32 PM Tom_L: i need to fine tune mine some, it's coming out a little crooked but certainly better than the lathe result
10:33 PM skunkworks: yes xl. mainly because I already had some pullys
10:34 PM skunkworks: who knew pullys has an 'e' in it..
10:34 PM Tom_L: heh
10:38 PM skunkworks: this will give me 5:1 and 4:3 reductions
10:38 PM skunkworks: for the spindle
10:38 PM Tom_L: i'm kinda wondering when i get the new spindle motor if i should gear the spindle up a bit
10:39 PM Tom_L: right now it's about a .8:1 reduction
10:39 PM skunkworks: so - 0-1200 and 0-4500
10:39 PM Tom_L: and the new motor will only go up to 5600 rpm
10:39 PM Tom_L: close to what the sherline does i think, maybe a bit less
10:40 PM Tom_L: guess i shouldn't complain ehh?
10:40 PM skunkworks: the green machine has a over and under drive pully setup
10:40 PM skunkworks: I think the motor is 6000rpm and it goes to 10k and 4k iirc
10:40 PM Tom_L: the sherline did but when i went to timing pulleys, i just used a single one
10:40 PM skunkworks: I am not overdriving the lathe.. 4500rpm is more than enough
10:40 PM Tom_L: i'm looking at a 1.2kw bldc
10:41 PM skunkworks: nice - the green machine is only 700w
10:41 PM Tom_L: you get pretty good results with it?
10:41 PM Tom_L: i could get a 750w version
10:41 PM Tom_L: a little cheaper
10:41 PM skunkworks: although I think I am pushing a lot more power with the stmbl drive..
10:42 PM skunkworks: I think it is good...
10:42 PM skunkworks: but more is usually better
10:42 PM Tom_L: it's hard for me to judge since i can't seem to find solid numbers on the stock sherline motor
10:42 PM Tom_L: i suppose bigger is better :)
10:42 PM skunkworks: ;)https://www.youtube.com/watch?v=dIxHASm5ev0
10:42 PM skunkworks: ;)https://www.youtube.com/watch?v=dIxHASm5ev0
10:43 PM skunkworks: heh
10:43 PM skunkworks: https://www.youtube.com/watch?v=dIxHASm5ev0
10:45 PM Tom_L: i'd like to cut a keyway on the spindle but i don't think it's got enough meat on it given the thru hole
10:46 PM skunkworks: Tom_L: https://www.youtube.com/watch?v=E2t0y2EsSO8
10:46 PM skunkworks: that was taking some ok cuts
10:46 PM skunkworks: didn
10:47 PM skunkworks: didn't seem to slow it down
10:47 PM Tom_L: i can do full width cuts with 1/4" maybe .185 deep but it gets hot quick
10:48 PM skunkworks: accoding to the meters - the spindle was taking about 400-500w
10:49 PM skunkworks: at 4000rpm (so geared down)
10:49 PM skunkworks: dullish mill
10:50 PM Tom_L: https://www.youtube.com/watch?v=VUDHCXu4Pwo&t=8s
10:50 PM Tom_L: around 4:30
10:51 PM Tom_L: i'm sure i could go faster but the spindle just won't take it
10:52 PM skunkworks: hence the water cooling?
10:53 PM Tom_L: yeah it helps a bunch
10:53 PM skunkworks: is that bldc?
10:53 PM Tom_L: i empty the ice tray in the 5gal bucket
10:53 PM Tom_L: no
10:53 PM skunkworks: ah
10:53 PM Tom_L: just stock dc sherline
10:53 PM skunkworks: ok. so the inside gets hot..
10:53 PM Tom_L: i'll be switching to bldc
10:54 PM skunkworks: that is what is nice about bldc - the heat is on the outside - easier to disapate..
10:54 PM Tom_L: i'm surprised it did as well as it did on that
10:54 PM skunkworks: sure!
10:54 PM Tom_L: huh, didn't know that
10:57 PM Tom_L: without the cooling it would be too hot to touch
10:58 PM Tom_L: skunkworks, are you gonna make the bar fit inside the pulley or just turn it down and key it?
10:59 PM Tom_L: no sound on this pc so no tellin what you said on the yt
10:59 PM skunkworks: it wasn'tt that good
11:00 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200809_201340.jpg
11:00 PM skunkworks: that hole gets a keyway
11:00 PM Tom_L: oh i missed the mate the first time :)
11:00 PM skunkworks: this goes on the dc motor on the emco
11:01 PM Tom_L: how many teeth is that pulley?
11:01 PM Tom_L: 30ish?
11:01 PM skunkworks: small one is 14 - big is 36
11:01 PM Tom_L: i'm concerned about belt contact patch on the spindle
11:02 PM Tom_L: i think i was looking at around 24 26ish tooth
11:02 PM Tom_L: and can't decide whether to go 1:1 or bump it up a bit
11:02 PM skunkworks: I am a bit worried about this too.. I will let you know ;)
11:02 PM Tom_L: although i'm running a GT2 on this now and it hasn't given me any problems
11:03 PM Tom_L: i did have it apart the other day to count the teeth and there was some belt dust all over it
11:04 PM Tom_L: since the spindle is too thin to slot, i may pin the back side of it with a screw turned down on the end
11:10 PM Tom_L: how wide is your belt? 15mm?
11:11 PM Tom_L: i think mine is 9 now and i'm not sure i have room for 15 but i'd like to
11:21 PM skunkworks: Tom_L: 3/8
