12:00 AM veegee: ugh
12:06 AM veegee: I overtightened the oil drain bolt on my makita mac5200 air compressor
12:06 AM veegee: now the case is cracked. stupid design. That area should be reinforced
12:06 AM veegee: Luckily I can still return it, but it's a pretty good compressor. Maybe some JB weld can seal the crack
12:06 AM Connor: Not a chance I would take on a pressure vessel.
12:11 AM veegee: the oil sump isn't pressurized
12:11 AM veegee: also just the cover part of it is cracked, part #29 on this diagram: https://www.ereplacementparts.com/makita-mac5200-air-compressor-parts-c-97_1547_1548.html
12:11 AM veegee: I guess I can order a replacement
12:13 AM veegee: these things really should have an oil filter. There's so many visible metal particles in the oil, especially after the first early oil change
12:51 AM flyback: <veegee> I overtightened the oil drain bolt on my makita mac5200 air compressor
12:51 AM flyback: <veegee> now the case is cracked. stupid design
12:51 AM flyback: no
12:51 AM flyback: STUPID CANUCK
12:51 AM flyback: STUPID CANUCK
12:51 AM flyback: STUPID CANUCK
12:51 AM flyback: STUPID CANUCK
12:51 AM * flyback DUCKS
12:51 AM veegee: I tightened the bolt with a screwdriver
12:51 AM veegee: not a wrench
12:51 AM veegee: and I'm not exceptionally strong
12:52 AM flyback: but you are canadian
12:52 AM veegee: might have been a defective casting
12:52 AM flyback: it's not part of the pressure system right?
12:52 AM veegee: No
12:53 AM flyback: might be ok then with jbweld etc
12:53 AM veegee: You can run it with the oil cap off
12:53 AM flyback: if it was part of the pressure system i'd scrap it
12:53 AM flyback: not worth it peeling like a bannanna
12:53 AM flyback: and killing you
12:53 AM veegee: Yeah, if the JB weld fails, I'll probably order a replacement part. If it's anything pressurized, I wouldn't even touch it
12:54 AM veegee: I'm looking into getting a 2 stage 10hp compressor like this one once I solve my power problem: https://eatoncompressor.com/product/10hp-v4-3-phase-80-gallon-vertical-air-compressor/#technical-specifications
12:54 AM flyback: I need to fix my oilless
12:54 AM flyback: it has a bad valve from rolling over in the car
12:54 AM veegee: I'll probably just hook up a VFD to it and run it at low power and hopefully the pump doesn't mind that in the meantime
12:54 AM flyback: they want $60 for anew manifold
12:54 AM flyback: I cna get a diapham kit for $20 on ebay
12:54 AM flyback: it was a like $150 porter cable compressor
12:54 AM flyback: paid $30
12:54 AM flyback: display model
12:55 AM flyback: use it for pc dusting at wowrk
12:56 AM flyback: i REPLACED THE DRain cock with a modern one turn type
12:57 AM flyback: best $% ever
12:57 AM flyback: going to get dad one for his
01:12 AM Deejay: moin
02:15 AM XXCoder: yay got materials for testing stuff
02:15 AM XXCoder: HDPE type from my soylent bottle, mini coke can metal, alum thin block
02:15 AM XXCoder: plan to grab paper for testing also
04:01 AM Tom_L: morning
04:01 AM XXCoder: hey
04:13 AM Loetmichel: mornin'
04:14 AM XXCoder: yo
04:56 AM jthornton: morning
04:56 AM XXCoder: yo
07:25 AM veegee: The hard to turn speed control dial problem went away by itself
07:26 AM veegee: I guess the belt dressing just needed some time to soak in? I don't know. It feels normal again after running the motor for a few minutes.
07:26 AM XXCoder: only thing worse than odd issue is odd issue that solves itself, leaving you with NOTHINg to prevent its return
07:26 AM veegee: Well it only happened when I swapped the motor and sprayed belt dressing while I was in there
07:27 AM veegee: it was fine before, and is fine again now. Based on how it works, I'm guessing the belt dressing made it harder for the belt to move with the pulley
07:27 AM XXCoder: probably rubbed off
07:27 AM veegee: or that yeah
07:27 AM veegee: at least on the edges that are in contact with the pulley
07:28 AM veegee: belt is quieter now too
07:28 AM veegee: Also Vactra #2 isn't that great... I sampled a whole bunch of way lubes from a local machine oil provider
07:29 AM veegee: Petro Canada way lube 68 feels much better. Even on my tools like knipex pliers wrench and so on, feels much smoother and more tackier. Going to buy a pail of the Accuflo TK 68 which has a lot more tackifier in it for the vertical slide way and other tools
07:32 AM veegee: vactra #2 has a lot more stick slip. Everything feels much smoother on the PC waylube 68. I bought 20 litres of it, should last me a few years. I pump the central oiler way more times that I need to. Oil is cheaper than a rebuild
07:33 AM veegee: Also going to add a second central lube for the lead screws and vertical slideway and use a higher viscosity oil with more tackifier
07:34 AM XXCoder: heh I do need to evenually lube my cnc router. my laser engraver is also unlubed, will need to handle that also.
07:34 AM XXCoder: it has plastic wheels with bearings, on extrusions
07:34 AM XXCoder: not sure what to use
07:34 AM veegee: bearing grease
07:35 AM veegee: Lithium complex EP with molybdenum disulphide. This is what I use: https://www.amazon.ca/Valvoline-SynPower-Synthetic-Automotive-Grease/dp/B000CQ4DK0/
07:37 AM veegee: Or this: https://lucasoil.com/products/grease/lucas-x-tra-heavy-duty-grease or this: https://lucasoil.com/products/grease/red-n-tacky-grease depending on if you want calcium complex or lithium complex
07:37 AM XXCoder: problem is machines is quite small
07:37 AM XXCoder: grease gun would be massive
07:40 AM veegee: use a needle injector
07:41 AM veegee: but a thick bearing oil would also work
07:41 AM XXCoder: ill have to be careful not to increase rolling reistance
07:42 AM XXCoder: steppers is weak lol
07:43 AM XXCoder: well off to bed. later :) thanks
10:54 AM gregcnc: veegee people run compressors slow with a VFD to keep them quiet
12:04 PM elmo40: veegee, eww, Lupus products.
12:42 PM unterhaus: I should have bought another piece of mic6 to mount the cross slide encoder with
12:42 PM unterhaus: Ain't it always the way
12:57 PM _unreal_: ? That was wierd
01:00 PM elmo40: _unreal_, all done the mill?
01:09 PM _unreal_: HARDLY
01:11 PM gregcnc: machining related, but not sure about nsfw https://www.instagram.com/p/B7tst4poWn8/
01:12 PM _unreal_: gregcnc, why are you posting pinkvampires shit?
01:15 PM _unreal_: ok just ordered my timing belts
01:15 PM gregcnc: has pink been around?
01:18 PM _unreal_: she was in a few days ago as I reacall
01:18 PM _unreal_: only spoke for like 10min then idled
01:18 PM _unreal_: speaking of idling lunch time
01:23 PM _unreal_: hotdogs are now starting to cook
02:38 PM _unreal_: ve7it, hi
02:40 PM * t4nk_freenode slaps _unreal_ around 'quiet' a bit with a large threaded rod
02:48 PM _unreal_: ve7it, when your around few questions about setting up the PSU
02:49 PM _unreal_: t4nk_freenode, you dont get to slap any one around till you build a working mill
02:49 PM ve7it: _unreal_, whats up?
02:52 PM t4nk_freenode: *sigh* it'll be a while b4 I can really slap the dross out of you then
02:52 PM _unreal_: ve7it, ok
02:52 PM _unreal_: so
02:53 PM t4nk_freenode: thinking about building a small lathe first
02:53 PM _unreal_: in that schematic. will that output 24v? or 20v?
02:54 PM t4nk_freenode: but for now I got some walls to paint, stuff to move, appliances to buy
02:55 PM _unreal_: t4nk_freenode, as I've said multi times I'd suggest following my design concept if you build. VERY simple
02:56 PM _unreal_: and $$ cheap
02:56 PM ve7it: _unreal_, I dont have the schematic here... if you have a transformer that measures 18VAC, when run through a rectifier the caps will charge up to (18-0.7) * 1.414 or about 24.5 V unloaded
02:57 PM t4nk_freenode: which design, you're building 16 different ones
02:57 PM _unreal_: https://www.powertronix.com/userfiles/kcfinder/images/Linear-Power-Supplies-4.jpg
02:57 PM _unreal_: t4nk_freenode, 17, keep up
02:57 PM t4nk_freenode: but I'm gonna experiment with building a small metal lathe to begin with
02:58 PM t4nk_freenode: seems nice
02:58 PM ve7it: It will probably drop to around 20V under load depending on how big your filter caps are
02:59 PM _unreal_: What sized caps should I get?
03:00 PM ve7it: whatever big screw terminal caps you can scrounge... maybe something like 20000uf @35V or higher
03:01 PM _unreal_: 2x 20,000uF or greater. ok
03:02 PM _unreal_: I may have to order
03:02 PM _unreal_: ve7it, I just ordered my belts finally
03:02 PM ve7it: 1000 is way too small and 47000 is getting pretty big (and expensive)... got any old stereo amps to disect? get the heaviest one you can find at the goodwill shop... it will probably have 2 big caps in it
03:03 PM _unreal_: 72" 720xl timing belts
03:03 PM _unreal_: ! good point
03:03 PM _unreal_: sigh... milling a new single block for my drive nut for one of the lead screws
03:04 PM _unreal_: I messed up my mounting holes. two low
03:04 PM _unreal_: to low
03:04 PM _unreal_: pressed on the poly around the lead screw and causes aggressive tension. got to make a new one.
03:04 PM _unreal_: thankfully only one
03:05 PM _unreal_: very glad I designed the drive nuts how I did
03:05 PM ve7it: I am hand wiring a circuit that I should have made a PCB for.... taking forever...
03:05 PM _unreal_: hehe
03:06 PM _unreal_: ya I've built a few via perf that I wished to HELLLLLLL I had just done in kicad and etched
03:07 PM ve7it: my eyes can only work on that stuff for so long.... hard to handwire in 805 size caps!, But thats all I had for 0.1uf.
03:07 PM ve7it: they pretty much disappear in a blob of solder
03:07 PM _unreal_: heh
03:08 PM _unreal_: ve7it, are you using an iron or hot air?
03:08 PM ve7it: I have both, both I am using soldering pencil on perf board at the moment
03:09 PM _unreal_: heh
03:09 PM _unreal_: ya my fave is to use my solder syringe, to put down solder paste, then knock it with the hot air
03:11 PM _unreal_: pink_vampire, you missed some .... interesting .... posts
03:12 PM pink_vampire: what posts?
03:14 PM pink_vampire: _unreal_: ?
03:15 PM miss0r: goodevening
03:21 PM pink_vampire: hi miss0r
03:21 PM miss0r: hey pink_vampire. You up to anything interresting?
03:21 PM pink_vampire: mostly 3d printing stuff
03:23 PM miss0r: Meh :) Some find that more interresting than others :D
03:25 PM miss0r: I don't think I'll ever get around to getting a 3D printer.
03:26 PM pink_vampire: some of the stuff that I printed will be almost impassible to machine from solid, and not very cost effective.
03:29 PM miss0r: No doubt! that is where 3D printing is worth its while. But usualy I would just redesign stuff to fit for conventional machining
03:44 PM * JT-Shop wonders where the micro SD card for the Mavic is...
03:50 PM Tom_L: chickens movin stuff around on ya again?
03:51 PM veegee: JT-Shop on the other side, under a cover that's the same colour as the body so it's hard to see
03:51 PM veegee: or did you mean you misplaced it?
03:52 PM JT-Shop: naw, just could not see it in the slot until I put on my magnifiers... I thought it was misplaced
03:53 PM JT-Shop: I know where it goes but it does go deep into the slot...
03:55 PM JT-Shop: now I wonder why vlc doesn't play them straight through
03:55 PM JT-Shop: it freezes... maybe 4k is too much for it lol
04:02 PM * JT-Shop has to make a headstone jack for the neighbor
04:13 PM unterhaus: someone crashed a plane about a half mile from here
04:13 PM unterhaus: changing it up from all the goofballs crashing cars at the next intersection over
04:23 PM Deejay: gn8
04:29 PM JT-Shop: a real plane?
04:29 PM _unreal_: pink_vampire, hi sorry my daughter begged me to play some foos ball
04:29 PM unterhaus: that's funny, it was reports of a plane crash, but actually someone just blew up some tannerite
04:31 PM _unreal_: pink_vampire, msg
04:37 PM JT-Shop: talk about making up shit
04:38 PM _unreal_: JT-Shop, ?
04:39 PM JT-Shop: tannerite
04:39 PM JT-Shop: calling it a plane crash
04:39 PM _unreal_: ?
04:40 PM gregcnc: was the tannerite in the plane?
04:45 PM unterhaus: people are silly about plane crashes
04:46 PM unterhaus: I guess there was an explosion and a cloud of smoke and they thought it was a plane crash
04:46 PM unterhaus: I worked with someone that built a plane. His dad was flying it solo when he had a heart attack, which he reported, but then he died
04:47 PM unterhaus: crashing the plane.
04:47 PM unterhaus: people on the ground swore that the plane burst into flames mid-air
04:47 PM JT-Shop: lol
04:47 PM JT-Shop: not at the guy that died but the dumb ass people
04:48 PM unterhaus: i have done crash investigations, you can't trust eyewitness accounts
04:49 PM unterhaus: I doubt a private plane would have a sharp explosion when it crashed
04:50 PM CaptHindsight: whycome nothing is being done about dumbass people?
04:51 PM unterhaus: nothing can be done
04:51 PM CaptHindsight: https://source.mntmn.com/MNT/reform/src/branch/reform2-nitrogen8m/case-parts
04:52 PM CaptHindsight: source files for the case https://www.omgubuntu.co.uk/2020/01/mnt-reform-open-source-laptop
04:55 PM CaptHindsight: Jimmy Kimmel does the man in the street interviews with completely made up stories and people just make up answers and comments about them
04:56 PM CaptHindsight: Jay Leno used to as well but he would use facts
04:56 PM CaptHindsight: have we reached peak stupid yet?
04:57 PM gregcnc: i think we have a way to go
05:01 PM ce9a: hi
05:02 PM ce9a: how do i get started with linuxcnc, ive just got linuxcnc sim install on my arch distro
05:02 PM unterhaus: there is no peak to stupid
05:02 PM unterhaus: do you have a machine in mind?
05:03 PM CaptHindsight: ce9a: control some steppers off a LPT port
05:03 PM ce9a: i have parrallel breakout board and im planning on doing a test run on bench
05:04 PM CaptHindsight: get the hang of the settings in the config files
05:04 PM XXCoder: hey pink_vampire
05:04 PM CaptHindsight: scaling, acceleration, velocity, polarity of switches etc
05:06 PM ce9a: CaptHindsight, ok cheers ill get everything wire up,
05:09 PM Tom_L: dumbass and stupid are a tightly nit group. we don't wanna upset their balance
05:10 PM unterhaus: it's a lot of fun to drive some steppers around with linuxcnc. Shouldn't take long to set up, couple of hours maybe
05:32 PM _unreal_: ve7it, guess its time to go to good will see if I can find me some caps ;)
05:35 PM _unreal_: some good news I JUST finally finished the Y axis drive system
05:35 PM _unreal_: god what a pain that was
05:35 PM _unreal_: one side kept giving me troubles
05:35 PM _unreal_: finally I gave up and tightened everything was I was doing and it just wouldnt move freely. took the fucking nut off and then ran the tap through it again.
05:35 PM _unreal_: was amazing how much material I removed
05:35 PM _unreal_: put the nut back on. and smooth as glass
05:36 PM _unreal_: I also had to remill one of the parts beause it totally failed do to the odd over resistance issue I was having
05:48 PM pink_vampire: hi XXCoder brb
06:11 PM unterhaus: the fire department sent 9 - Engines
06:11 PM unterhaus: all for a tannerite explosion
06:12 PM unterhaus: most of them were sent back en route
06:12 PM Tom_L: waste of resources
06:14 PM unterhaus: I don't know why you would send so many. Couldn't have been a big plane, so that's too much stuff
06:15 PM Tom_L: i can see it if it were a plane. they wouldn't know what size it was
06:16 PM Tom_L: 1 cop got shot here quite a while back and there were a minimum of 35 cop cars on the scene
06:33 PM unterhaus: that's a bit different, I think
07:09 PM beachbumpete1: Hey folks
07:09 PM beachbumpete1: howzitgoin?
07:20 PM beachbumpete1: Well I am pleased to announce that my damn spindle is currently running thru a break in procedure and it is up to 5k RPM without issue so far. I can't believe it. I really thought I was FUBAR with these new bearings....
07:21 PM beachbumpete1: Maybe now I can get back to the business of making cool parts eh? hehehe
07:21 PM Tom_L: what'd you do to fix it?
07:21 PM beachbumpete1: Honestly I just took it all apart and put it back together. Did not find anything I could point at that was a problem with anything
07:22 PM CaptHindsight: was it quieter after rebuild or did you just push through the early noise?
07:22 PM Tom_L: well that's good news
07:22 PM beachbumpete1: This machine has only a 6k RPM max spindle
07:23 PM beachbumpete1: CaptHindsight: I tried to push thru but it just sounded like shit
07:23 PM beachbumpete1: so I took it apart again
07:23 PM beachbumpete1: like I said I did not find anything wrong tho
07:23 PM CaptHindsight: yes, i mean after the 2nd rebuild
07:23 PM beachbumpete1: so I just cleaned everything and put it back together
07:23 PM CaptHindsight: was there less noise the 2nd time?
07:24 PM beachbumpete1: oh yeah man much less noise altho no idea why
07:24 PM CaptHindsight: or same noise but you just kept upping the rpm
07:24 PM CaptHindsight: ah ok
07:24 PM beachbumpete1: before I could not get past 2k
07:24 PM CaptHindsight: well good that it's ok now and nothing expensive happened
07:24 PM beachbumpete1: I will say that now that we are at 5k it seems to be a little louder than it was in my memory of the original spindle bearings right now.
07:24 PM Tom_L: i've found it doesn't take much to make a bearing unhappy
07:25 PM beachbumpete1: I normally ran all my programs at like 5k or so
07:25 PM CaptHindsight: I'm sure your adjustment of the bearing was much better this time
07:25 PM beachbumpete1: that must be it really..
07:25 PM CaptHindsight: if it was even off before
07:25 PM beachbumpete1: I set the preload the same way with the same only torque wrench I own large enough
07:25 PM CaptHindsight: new grease?
07:26 PM beachbumpete1: no I did not put new grease in it because the labryinth seal at the bottom makes accessing the lower bearing nearly impossible.
07:26 PM beachbumpete1: I am HOPING that once I start running it again it will continue to smooth out
07:26 PM CaptHindsight: \0/
07:27 PM beachbumpete1: Very thankful that it is working right now
07:27 PM beachbumpete1: I have a few faithful customers that have been waiting for me to get it back together so I can make them some parts
07:27 PM beachbumpete1: It has literally been running continuously since 7am this morning
07:28 PM beachbumpete1: I keep checking the spindle bore and top with my digital thermometer
07:28 PM beachbumpete1: and it has never got above 95 degrees f
07:29 PM beachbumpete1: I think I will run it up to 5500 and then shut it down for the evening hopefully it will continue to run smoothly
07:29 PM beachbumpete1: My damn coolant troughs are nasty from not running and sitting stagnant for a couple weeks/month or so now
07:30 PM beachbumpete1: gonna have to pump them out and remix some new juice
07:30 PM XXCoder: beach yeah thats why cnc machines cannot be idle
07:30 PM XXCoder: shop I work at is trying to keep a61 running. we are little too adhread. 737 max hurt it a bit
07:30 PM beachbumpete1: Well honestly I normally have an aquarium bubbler on both tanks
07:30 PM XXCoder: we was supposed to have certain part thats infinite amount needed
07:31 PM beachbumpete1: but the surgical tube got ripped off when I was cleaning up out there one weekend and I have not gotten some new stuff to replace it.
07:31 PM XXCoder: doh
07:31 PM beachbumpete1: OTherwise it can normally sit for a long while without any issues
07:31 PM beachbumpete1: To be honest with you guys
07:31 PM beachbumpete1: I was getting kinda despondent with this whole damn situation
07:32 PM beachbumpete1: I spent all that money and took everything apart cleaning everything carefully
07:32 PM beachbumpete1: and wound up with spindle bearing issues
07:32 PM beachbumpete1: so I kinda just let it sit for awhile
07:32 PM beachbumpete1: got my head into other things
07:32 PM beachbumpete1: while I think about what to do with it.
07:34 PM XXCoder: lol wonder if bearings are paired
07:34 PM XXCoder: if so, is it specific order paired
07:34 PM XXCoder: saw robertez video about it. he goes though insane careful calbrations while rebuilding his mill spindle'
07:37 PM XXCoder: hell he even rotates bearings so spindle rod stays stright
07:37 PM XXCoder: rather lengthy video
07:38 PM XXCoder: https://www.youtube.com/watch?v=grUdsTTRGl4 this one
07:38 PM XXCoder: its hour and half long. get snacks
07:39 PM XXCoder: i do recommand it even if machine dont match yours
07:39 PM beachbumpete1: I think I watched that one hehe
07:41 PM beachbumpete1: Just bumped it up to 5300
07:41 PM XXCoder: its pretty good :)
07:41 PM beachbumpete1: still sounds ok
07:44 PM veegee: I'm about to get this split beam torque wrench: https://www.amazon.ca/Precision-Instruments-PREC3FR250F-Silver-Torque/dp/B002XMSFIM
07:44 PM veegee: Unless someone can advise me not to
07:46 PM XXCoder: reviews says "click" is not olvious
07:46 PM XXCoder: useless for me, dunno for you
07:53 PM veegee: at low torque settings yeah
07:53 PM veegee: that's pretty much every torque wrench ever
07:57 PM CaptHindsight: veegee: looks nice, anything decent will be similarly priced
07:57 PM XXCoder: ones at work does pretty good click even at lower torque
07:58 PM CaptHindsight: I can usually feel the click
08:00 PM CaptHindsight: https://www.youtube.com/watch?v=pBmjpBVl9WY I got one of these on ebay for < $100
08:00 PM veegee: Ah so the electronic ones, are they "click type" mechanism internally?
08:00 PM veegee: If so, how do you turn them down after use
08:00 PM XXCoder: yeah I wanna know if it click
08:01 PM XXCoder: none of that beep crap
08:01 PM veegee: well they beep
08:01 PM XXCoder: usless then
08:01 PM veegee: as you approach the torque
08:01 PM CaptHindsight: https://www.youtube.com/watch?v=LcC2AXVzNHk actually this one
08:02 PM CaptHindsight: veegee: mine works this way https://youtu.be/LcC2AXVzNHk?t=378
08:02 PM XXCoder: if it just beeps I cant hear it so I cant use it
08:02 PM veegee: You can't hear beeps?
08:02 PM XXCoder: or anything else heh
08:02 PM veegee: Some of them vibrate
08:02 PM veegee: for your pleasure
08:02 PM XXCoder: lol
08:02 PM XXCoder: what? no ribs?
08:02 PM veegee: The Gear Wrench ones vibrate and beep and flash an LED
08:03 PM veegee: human tactile sense ability is incredible though, also vision
08:03 PM veegee: you can feel differences on the level of micrometers
08:04 PM veegee: and see slits on the level of micrometers as well, like between the faces of a micrometer measuring instrument
08:04 PM CaptHindsight: I use a beam type for preloading bearings
08:04 PM XXCoder: my vision is so amazing that evenually I will be unable to drive in nights because my night vision is so good that lights is blinding
08:04 PM CaptHindsight: old analog beam
08:04 PM veegee: yeah beam types are simple, cheap, accurate
08:05 PM CaptHindsight: click and digital click for automotive
08:05 PM veegee: I'm going to get a regular click type for the screws/bolts on my mill
08:05 PM CaptHindsight: bearings caps, rods, head bolts etc
08:05 PM veegee: Definitely don't want to crack any castings now
08:05 PM XXCoder: we must have hundred torque wrenches at work
08:06 PM XXCoder: foot and inch one each machine
08:06 PM XXCoder: and we have many machines

08:08 PM CaptHindsight: or similar if i was doing production and needed accuracy and repeatability
08:11 PM beachbumpete1: Well she is up to 5500 RPM highest temp I have recorded in the spindle bore has been 101f
08:11 PM beachbumpete1: it actually is sounding smoother as the speeds increase
08:12 PM beachbumpete1: hopefully that will translate into a smooth machine down lower where I normally run it
08:12 PM beachbumpete1: I was starting to think I would never get this thing going again LOL
08:21 PM CaptHindsight: I've adjusted bearings, twice to really be sure, come back on Monday and see I did something wrong
08:21 PM CaptHindsight: sometimes you don't notice what you did that was off
08:22 PM gregcnc: I'm still dealing with my spindle motor for my mill. i did put it all back together after trying a balance on the pulley end only. it's not terrible, but not right either
08:23 PM gregcnc: I'll try a full dynamic balance on my own. Take this motor apart yet again.
08:43 PM _unreal_: I SOOOO cant wait till monday to get my timing belt
08:43 PM _unreal_: belt'S
08:53 PM beachbumpete1: CaptHindsight Well I just got back in from the shop
08:53 PM beachbumpete1: I ran the spindle up in 200 RPM increments basically all day
08:54 PM beachbumpete1: I got it up to 5800 RPM
08:54 PM beachbumpete1: it sounded pretty smooth at that RPM and I was gonna push thru to the max RPM of 6k
08:54 PM beachbumpete1: but I noticed that the temp inside the spindle was starting to creep up slowly
08:54 PM beachbumpete1: it was at around 98 degrees f almost all day lone
08:54 PM beachbumpete1: g
08:55 PM beachbumpete1: but when I checked it last it had creeped up to 104

08:55 PM beachbumpete1: I decided that discretion is the better part of valor here
08:55 PM beachbumpete1: so I started slowing the spindle down incrementally
08:55 PM beachbumpete1: it is now shut off
08:56 PM beachbumpete1: so I THINK that is a successful run in
08:56 PM beachbumpete1: or at least as successful a run in as I could have expected at this point anyway
08:56 PM beachbumpete1: I normally machine my parts at around 5k or so
08:56 PM beachbumpete1: so this was considerably higher than I typically run and it was smooth
08:57 PM beachbumpete1: I am going to put the drawbar back on and hook up all the pneumatics in the morning and try to put a cutter in there and see if I can machine something
08:57 PM beachbumpete1: I don't think it will be a problem now not with that speed and smooth operation but only one way to find out.
08:58 PM beachbumpete1: It seemed like the longer it ran the smoother it began to sound.
08:58 PM beachbumpete1: I am optimistic that after a couple weeks of making parts it will be as quiet as it ever has been
08:59 PM beachbumpete1: If nothing else at least I can make some parts now and perhaps save up some cash in the piggy bank in case the new bearings fail prematurely sometime down the road.
09:00 PM beachbumpete1: Honestly at the almost 6k RPM it really was starting to sound like it did when I bought it quite a few years ago now.

10:13 PM jymmmm: XXCoder: hows your laser doing?
10:13 PM XXCoder: lat runs was good, i have various samples to try today. just chilling now tho
10:13 PM XXCoder: alum block, alum from soda can, vinyl sheet sampler, and hdpe sheet
10:22 PM jymmmm: Dont do PVC
10:22 PM XXCoder: i know that lol
10:23 PM jymmmm: vinyl = poly VINYL Chloride
10:23 PM XXCoder: but then whats little poison gassing along friends
10:23 PM jymmmm: XXCoder: I have a favor to ask
10:23 PM XXCoder: ah so that has that also?
10:23 PM XXCoder: dammit guess this card sample is useless now
10:24 PM Javabean: only for laser work
10:24 PM jymmmm: any other plastic but pv is fine
10:24 PM jymmmm: pvc*
10:24 PM XXCoder: its kitchen counter top sample tile
10:24 PM jymmmm: XXCoder: I have a favor to ask
10:25 PM XXCoder: what favir
10:26 PM jymmmm: XXCoder: Can you try to light a match at 10, 25, and 50 feet?
10:26 PM XXCoder: nah will not do that
10:26 PM jymmmm: can I ask why?
10:27 PM XXCoder: i would have to disassembly entire laser assebly to do that
10:27 PM jymmmm: XXCoder: just turn it on it's side
10:27 PM jymmmm: the whole thing
10:27 PM XXCoder: i suppose but im not firing laser outside too
10:27 PM XXCoder: 10 ft is barely can be in my room. rest is too long to be anywhere in house
10:28 PM jymmmm: open a window? lol
10:28 PM jymmmm: Ok, 10ft is fine
10:29 PM XXCoder: well there is another issue
10:29 PM XXCoder: noboldy here has matches lol
10:29 PM XXCoder: not willing to buy any
10:29 PM jymmmm: just book matches
10:29 PM jymmmm: cheap free ones
10:29 PM jymmmm: a piece of toilet paper, I dont care
10:31 PM XXCoder: lol
10:32 PM jymmmm: I just want to get an idea ont he range, before buying one
10:34 PM XXCoder: ya just cant test that for you unfortunately
10:35 PM jymmmm: ok
11:16 PM beachbumpete1: xxcoder are you building a CNC laser?
11:16 PM XXCoder: built.
11:16 PM XXCoder: couple weeks ago
11:16 PM beachbumpete1: what kind of laser?
11:16 PM XXCoder: oh cheao laser diode
11:16 PM XXCoder: 2w
11:16 PM beachbumpete1: what is the machine base?
11:17 PM XXCoder: base?
11:17 PM XXCoder: its 2020 frame :)
11:17 PM beachbumpete1: is it extrusions?
11:17 PM beachbumpete1: cool
11:17 PM beachbumpete1: I am tempted to slap one of those on my 3D printer frame
11:18 PM XXCoder: yeah 3d printer frame can do it
11:18 PM beachbumpete1: sure its been done a good bit ;)
11:20 PM XXCoder: ony thing im not ure is laser control
