01:44 AM miss0r: goodmorning
01:50 AM infornography: https://www.youtube.com/watch?v=FHMcoG_FmTw
05:02 AM jthornton: morning
05:23 AM miss0r: *afternoon
05:33 AM Deejay: hi
06:57 AM Tom_L: morning
08:17 AM skunkworks: Tom_L: fresh start?
08:17 AM skunkworks: :)
10:05 AM -!- #linuxcnc mode set to +v by ChanServ
10:48 AM Kevin` is now known as Kevin
10:56 AM rue_mohr: Tom_L, apt-get install apt-file then apt-file update then apt-file search realtime |grep init
10:57 AM rue_mohr: where is my get-up-and-go..
11:13 AM Tom_L: going thru dependency hell again
11:14 AM rue_mohr: yup, why did you mess with it?
11:14 AM Tom_L: mess with what? it is a fresh install
11:14 AM rue_mohr: yea
11:15 AM Tom_L: testing rtai on debian stretch instead of the lcnc stretch iso
11:15 AM ziper: how hard is it to make money by yourself with only a couple machines?
11:16 AM Tom_L: depends on your sources
11:16 AM Tom_L: if you have good contacts you can stay busy night and day
11:17 AM Tom_L: if you haven't a clue what you would make then that's a problem
11:18 AM ziper: yeah, figured
11:18 AM Tom_L: my friend started in his garage with a bridgeport tracer and ended up in a 60k sq ft building with a dozen or so cncs
11:19 AM Tom_L: ymmv
11:21 AM fenugrec: Conversely, you can find tons of 3d printers / small machine tools in the classifieds sold after a start-up collapsed...
11:21 AM Tom_L: you should have a good plan before you dive into the deep water
11:21 AM Rab: Craigslist is full of people offering CNC services, here.
11:22 AM Tom_L: are they certified or just making parts?
11:22 AM Rab: Some look like pro shops scrounging for work, others are more "have Shapeoko will travel".
11:22 AM Tom_L: heh
11:23 AM Tom_L: right now even the big shops are struggling
11:24 AM Rab: https://austin.craigslist.org/tls/d/san-antonio-cnc-machine-shop-services/7101918361.html
11:24 AM Rab: Tried to figure out those brass doodads for a while, eventually realized they must be for something like a wok burner.
11:28 AM ziper: a whille back I was shopping around to get some molds made, and nobody actually came through with a quote. either didn't respond or didn't want to do 3d work
11:30 AM gregcnc: metal?
11:31 AM Tom_L: that would be fairly expensive
11:31 AM ziper: not even, mdf
11:31 AM gregcnc: finding people to do that work is tricky
11:31 AM Tom_L: time consuming
11:31 AM gregcnc: for molding composites?
11:32 AM ziper: I ended up programming it myself and running on somebody elses machine (who didn't know how to use it). was making progress until everything shut down
11:32 AM ziper: yes
11:32 AM gregcnc: really depends on how big they are
11:32 AM ziper: 30x100 cm
11:32 AM Tom_L: so a single sided mold
11:32 AM gregcnc: seems like there are a fair number of RC airplane guys who do pane molds
11:33 AM gregcnc: plane
11:33 AM Tom_L: i did a few fiberglass molds years ago
11:34 AM gregcnc: I think depth is a bigger dimensional issue, ans many routers are limited in Z
11:34 AM Tom_L: yeah
11:34 AM ziper: only 3 cm
11:35 AM Tom_L: i helped another guy with a blower snout on a funny car once. he was using 8" ballnose and still barely reached
11:36 AM Tom_L: so your parts are fairly flat
11:37 AM gregcnc: router guys rarely do tolerance 3D and machine shops will be expensive, if they want to touch MDF
12:42 PM {HD}: Does tape mean wirenut? https://i.imgur.com/W2NmcH2.jpg
12:42 PM {HD}: as in P2, T8, and T3 should be connected together.
12:44 PM Loetmichel: hopefully it means "insulate wirenut/bridges from case" but i have no idea really
12:45 PM Loetmichel: <- german electrician
01:01 PM {HD}: Well I just wired it up and didn't not explode or get electrocuted so "tape" means connect together and insulate.
01:13 PM MacGalempsy: :)
01:18 PM Tom_L: twist nuts would be better
01:24 PM MacGalempsy: nothing like a relative selling their house to get one motivated to make room for his cnc.
01:26 PM {HD}: Tom_L: I eneded up using wire nuts for my test. "tape" seems like such a odd way to describe the wiring.
01:30 PM Rab: {HD}, I think "tape" is used as a synonym for "insulate". How you make the connections is up to you, as long as they're "taped" from the case.
01:32 PM Rab: This seems like an industry source: https://eecoonline.com/properly-insulating-motor-connections/
01:32 PM Rab: Note that in their video, wires are joined through bare lugs bolted together, then taped.
01:50 PM jymmmm: In the UK they have liquid paraffin, what is that in the US?
01:50 PM Tom_L: hot wax
01:53 PM jymmmm: No, this is liquid at room temperature
01:55 PM Tom_L: a very highly refined mineral oil used in cosmetics and medicine.
01:56 PM Loetmichel: sounds like waht the germans call "petroleum"?
01:56 PM Loetmichel: "lamp oil"?
01:56 PM Rab: jymmmm, kerosene?
01:56 PM Rab: jymmmm, what's the application?
01:57 PM fenugrec: jymmmm, you should be able to get pure paraffin oil sold as "pure lamp oil" - unscented, probably a bit lower distillate than kerosene ? less smell for sure
01:58 PM fenugrec: and much thinner than typical "mineral oil" from pharmacy
02:03 PM gregcnc: UK paraffin is US kerosene
02:04 PM gregcnc: though both terms are somewhat generalized
02:04 PM jymmmm: gregcnc: AH OK, I would have never consider it to be kerosene =)
02:05 PM snakedGT is now known as snaked
02:08 PM jymmmm: Charcoal bbq lighter fluid, zippo lighter fluid, and Coleman White Fuel are all really naphtha, just that Coleman adds rust inhibators to theirs
02:08 PM fenugrec: hydrocarbon nomenclature is possibly the worst pile of conflicting, vague terms evec
02:08 PM fenugrec: *ever
02:09 PM jymmmm: lol
02:09 PM fenugrec: so what're you making
02:10 PM jymmmm: Someone converted a candle lantern to an oil burning lantern, using parafin, just want to know what he was using
02:11 PM jymmmm: Although, someone had a hurricane lantern and broke the glass, so I kept the base and put in whatever I could find, cooking oil, etc, works pretty good other than a bit smokey
02:12 PM jymmmm: I might try used cooking oil (ran thur a coffee filter) and see how that burns
02:14 PM fenugrec: protip : regular paraffin oil is useless in cold weather in a wick lamp
02:15 PM jymmmm: fenugrec: really?
02:16 PM jymmmm: Cause we have kerosne heaters that work well in the winter
02:18 PM fenugrec: jymmmm, right - if I buy kerosene branded as kerosene here (in Canada), that would indeed work in the cold. Probably a cut similar to diesel; lamp oil ("paraffin") turns slushy/waxy at <0C temps
02:19 PM fenugrec: can't even pour that stuff at -10C
02:20 PM jymmmm: fenugrec: ah ok, I've never used kerosene, just naphatha and DNA (190 proof)
02:21 PM gregcnc: kerosene is not diesel
02:22 PM gregcnc: naptha is a also a general term
02:22 PM gregcnc: if you need something specific you need to be sure you know what you need
02:22 PM Loetmichel: jymmmm: rapeseed oil works well in kerosene lamps, except the petromax type that have an atomizer
02:22 PM gregcnc: what is this for?
02:22 PM Loetmichel: but anything with a wick is fine
02:22 PM fenugrec: no, I didn't say they were the same, but I'd expect they're close in the distillation column, similar BP etc.
02:23 PM gregcnc: kerosene is much lighter than diesel
02:24 PM Loetmichel: gregcnc: not THAT much
02:24 PM gregcnc: enough to matter
02:24 PM gregcnc: and enough not to mix them up in some applications
02:24 PM Loetmichel: its similar enough that a diesel can run on jet-a1 and vice versa
02:24 PM fenugrec: meh, I'll repeat : everyday hydrocarbon nomenclature is horrible
02:24 PM gregcnc: "might"
02:24 PM gregcnc: for a while
02:25 PM gregcnc: if built to run jet-A/kerosene a diesel will do it, otherwise the pumps will not be happy
02:25 PM Loetmichel: depends on the diesel engine i guess
02:25 PM gregcnc: compbustion doesn't care
02:25 PM Loetmichel: yes, jet-a1 isnt as lubricating as diesel, true
02:26 PM gregcnc: big differnce in viscosity
02:26 PM Loetmichel: if the engine has inlector pumps that are lubed by the fuel that could end badly
02:26 PM gregcnc: anyhow there is a wide range of specific distilates which fall in to the general categories
02:26 PM Loetmichel: but for example jet engines work well on diesel, been there done that
02:27 PM Loetmichel: agreed. its all similar but not exactly the same
02:29 PM jymmmm: Fiiine, two gallons of gasoline and a road flare, problem solved =)
02:29 PM Loetmichel: btw: did you know that old diesel egnines (without common rail/pump injectors) run pretty well on rapeseed oil, too?
02:29 PM Loetmichel: and i dont mean RME, i mean pure rapeseed oil
02:29 PM gregcnc: diesel run on coal dust if you can inject it
02:30 PM Loetmichel: start hard though, so you better start on diesel and switch to rapeseed oil once the engine is warm
02:30 PM gregcnc: I've read all those papers all veggie oils has been tested
02:30 PM Loetmichel: yes, so i have heard (coal dust)
02:30 PM gregcnc: copra is the best raw oil
02:30 PM Rab: My brother-in-law put bacon grease in his Mercedes for fun (vegetable oil conversion); ran fine.
02:30 PM Loetmichel: i have driven my old OPel omega on rapeseed oil for the better part of 4 years
02:31 PM Loetmichel: then the rapeseed oil at aldi got more expansive thatn the diesel at the fuel station ;)
02:31 PM Loetmichel: expensive
02:31 PM fenugrec: hehe I was reading in diagonal and read "Loetchemichal"
02:32 PM Loetmichel: started at 79 ct a liter while the diesel was 1.21 eur
02:32 PM Loetmichel: 4 years later it was at 1,35 eur while the diesel was at 1,29
02:33 PM Loetmichel: got a few funny looks though when i went to the local aldi, bought 60 1l bottles, went to the car and filled them all in the tank, then brought the cart back to get rid of the plastic bottles ;)
02:34 PM Loetmichel: only drove pure in the summer months though. in the winter it was 50% rapeseed and 50% diesel
02:34 PM Loetmichel: or it wouldnt start
02:35 PM Loetmichel: (probably because rapeseed oil gets tar-like properties at low temperatures, pump couldnt suck it thru the lines any more)
02:36 PM Thorhian: Wow this is quite the conversation lol
02:36 PM gregcnc: we cover ti all here
02:36 PM Loetmichel: hmm?
02:37 PM Loetmichel: Rab: the Opel omega wasnt a conversion
02:37 PM Loetmichel: standard issue diesel engine.
02:38 PM Loetmichel: or i wouldnt have had issues in the winter
02:38 PM Loetmichel: the conversions have a seperate tank that is heated by the engine coolant for the veg oil
02:38 PM Thorhian: Quick question, what is the project that is used with LCNC on the Mesa cards?
02:39 PM Loetmichel: and a valve to switch between diesel and veg oil
02:39 PM Loetmichel: no idea, sorry
02:40 PM Tom_L: what project?
02:40 PM Tom_L: a mill?
02:40 PM Thorhian: Sorry, the VHDL code for the mesa cards
02:40 PM Tom_L: what about it?
02:41 PM Tom_L: it's xilinx webpack
02:41 PM Tom_L: you can dl the source for the bitfiles from his site
02:42 PM Tom_L: here's a bit on bit files: http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php
02:42 PM Tom_L: not a project really, he provides source
02:44 PM Tom_L: and he provides enough compiled bit files you more than likely won't need to make one yourself
02:46 PM Tom_L: sry for interrupting... back to jymmmm's oil lamp :)
02:48 PM jymmmm: Tom_L it's all good, parrfin, kerosene is all I needed to know =)
02:49 PM Tom_L: just use gasoline in a coke bottle with a rag sticking out...
02:49 PM jymmmm: you forgot the dish soap
02:50 PM jymmmm: Pull string fire starter https://www.youtube.com/watch?v=oGe0XKW2nF4
02:51 PM jymmmm: Fuse start fire starter https://www.youtube.com/watch?v=Ux5NNLv1hOA
02:52 PM jymmmm: pull sting is $5, fuse start is $24 for the LARGE one.
02:52 PM jymmmm: I'm just KISS... 15minute road flare 3 pack $7, no match needed =)
02:54 PM Loetmichel: jymmmm: are those road flares the "scratch anywhere to light" kind?
02:56 PM jymmmm: Loetmichel: yeah
02:56 PM jymmmm: well, IDK about "anywhere"
02:56 PM jymmmm: there is a strike on the cap
02:56 PM jymmmm: striker*
02:59 PM jymmmm: Loetmichel: https://www.youtube.com/watch?v=sA2NfR_RQBI
02:59 PM jymmmm: Loetmichel: https://www.youtube.com/watch?v=bTEVXWeerCw
03:11 PM Thorhian: Sorry Tom_L I had to leave for a bit. I have the webpack already. I'll go to the site for the source. I'm going to see how hard it would be to put on my Nexys 4 DDR (has an Artix-7).
03:54 PM Tom_L: Thorhian, Artix-7 a newer chip?
03:54 PM Deejay: gn8
03:55 PM Tom_L: if so you will need newer tools than webpack for it
03:56 PM _unreal_: yall heard about this https://www.youtube.com/watch?v=HUr3-W6kFXo
03:59 PM Thorhian: Yeah Tom_L I have vivado. Too bad I don't have any real experience with VHDL or converting old ISE projects to Vivado.
04:00 PM Thorhian: I have only learned Verilog XD
04:01 PM pcw_home: I would expect Vivado to convert project files automatically
04:01 PM Thorhian: Oh it does, problem is I don't know how to fix the error coming up (plus UCS constraint files are unsupported).
04:01 PM Thorhian: errors*
04:02 PM pcw_home: ucf files are not supported/translated?
04:02 PM Thorhian: I guess I better learn VHDL first lol
04:04 PM Thorhian: UCFs are not converted and aren't supported. I have a different constraint file for the Nexys 4 DDR that I can wire up when I figure things out.
04:06 PM pcw_home: Yeah it looks like there's a tool to convert from .ucf to .xdc
04:07 PM Thorhian: Interesting. I'll look for it.
04:08 PM pcw_home: but there are some differences in coverage, .xdc has no timing constraints so that has to be setup with some other tool
04:08 PM Thorhian: Oh boy lol
04:09 PM Loetmichel: jymmmm: so basically a big bengal light
04:09 PM Loetmichel: SURE, that will get the fire going ;)
04:09 PM Loetmichel: h,, i wonder if those are (road)legal in germany
04:09 PM Loetmichel: i have seen german police use them
04:10 PM Loetmichel: lets google a bit?
04:11 PM jymmmm: They are in the US
04:11 PM jymmmm: even in Commifornia =)
04:12 PM gregcnc: are EU countries postal systems accepting international mail?
04:13 PM jymmmm: Loetmichel: Fire starter, signal flare, self defense, Critter deterant
04:16 PM pcw_home: gregcnc they are overloaded/understaffed so for example priority mail is now taking 3 weeks or longer
04:17 PM gregcnc: wow ok
04:17 PM pcw_home: (no delivery guarantees with priority now)
04:17 PM gregcnc: i did see that
04:17 PM jymmmm: Six 30 (or 20) minute flares are $20 ($0.11/minutes, Three 15 minute flares are $7 ($0.16/minute). Just really depends on how long of a flare you can carry/toss in a backpack.
04:22 PM Loetmichel: jymmmm: fyi: in germany T1 class road flares are legal to have in the car. Class 4 are NOT legal, thats a (explosives) felony, not only a misdemanor.
04:22 PM jymmmm: Loetmichel: what is T4?
04:23 PM Loetmichel: problem is that the ONLY german manufacturer is in the process to renew those flares as T1 with the effect that you cant buy any that have "T1" written on them. :-(
04:24 PM jymmmm: you mean T4?
04:24 PM jymmmm: what is defined as T4?
04:25 PM Loetmichel: T1 and Class4 are explosives categorys in germany
04:26 PM Loetmichel: T1 is "end user allowed" like the fireworks at new year, class4 you need an explosives permit to handle or it is a felony if you get caught with them
04:27 PM jymmmm: Loetmichel: Ok, just say you are going to do some gardening and have some sulfur, stump remover and charcoal in the car at all times =)
04:27 PM Loetmichel: hrhr
04:28 PM Loetmichel: or some anhydrid fertilizer and a jerry can of diesel ;)
04:28 PM jymmmm: or zinc powder and sulfur.... FUCK THAT SHIT BURNS FAST, I mean REALLLY REALLY FAST
04:28 PM jymmmm: aka rocket fuel
04:29 PM Loetmichel: ground rust and ground aluminium is good as well ;)
04:30 PM Loetmichel: as i said: those flares are (road) legal in germany IF they have the T1 marking
04:30 PM Loetmichel: if they dont have that: biiig problem... IIRC that can send you to jail for 5 years in bad cases.
04:30 PM Loetmichel: not only some fine.
04:30 PM jymmmm: Loetmichel: https://youtu.be/nzKpPZW7Aco?t=212
04:32 PM jymmmm: Loetmichel: https://youtu.be/t8k9yaz-7Rs?t=431 (same stuff)
05:51 PM jymmmm: Makita coffee maker (and actually looks kinda cool)... https://youtu.be/3-uV9AJAcDA?t=376
05:51 PM pink_vampire: hi
05:51 PM jymmmm: Pinky!!!!!
05:51 PM jymmmm: Pinky https://youtu.be/3-uV9AJAcDA?t=376
05:52 PM pink_vampire: I think there is missing part in my lathe
05:52 PM pink_vampire: jymmmm!!!!!!
05:52 PM jymmmm: =)
05:52 PM pink_vampire: jymmmm: cool! I don't touch coffee
05:53 PM jymmmm: tea, cocoa, whatever =)
05:53 PM jymmmm: batter powerder coffee maker
05:53 PM jymmmm: Jsut thought it was kinda cool, never heard of it beter
05:53 PM jymmmm: before(
05:53 PM jymmmm: *
05:54 PM pink_vampire: Don't get me wrong, it is Super cool!!
06:01 PM pink_vampire: Is there a saddle lock on the maximat 7?
06:14 PM snakedGT is now known as snaked
07:14 PM gregcnc: knurl
07:15 PM gregcnc: if anyone was wondering I'm searching Ebay for knurls
07:15 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200416_185702.jpg
07:15 PM * skunkworks thinks it is gregcnc password...
07:16 PM gregcnc: lol
07:16 PM gregcnc: i actually just checked to see if there was a second video for the upgrade
07:17 PM pink_vampire: gregcnc: any time you are coming to NY soon? I have a box full with knurls that are too large for my lathe
07:17 PM gregcnc: I'm looking for small ones
07:18 PM skunkworks: gregcnc: not yet..
07:18 PM pink_vampire: 1/2" and 3/4" shank is small enough for you?
07:19 PM gregcnc: 1/2 shank works, but I'm looking fro very specific types, hoping not to shell out 500USD
07:19 PM skunkworks: I think I have all the material.. bearings and such too.
07:22 PM pink_vampire: skunkworks: for?
07:31 PM skunkworks: pink_vampire: I thought you saw this https://youtu.be/VmWeXS6y-lg
07:34 PM pink_vampire: I saw it, but I thought your are talking about the knurls
07:34 PM pink_vampire: my shop-light just died!!
07:34 PM pink_vampire: I'm in the dark
07:35 PM skunkworks: heh
07:35 PM pink_vampire: Any idea how to bring it to back life again? https://i.imgur.com/GlDap0z.png
07:35 PM skunkworks: pink_vampire: buy led replacments?
07:36 PM pink_vampire: everything is closed here
07:36 PM skunkworks: order them ;)
07:36 PM skunkworks: pink_vampire: have you ventured out at all?
07:37 PM pink_vampire: no, I'm at home
07:37 PM pink_vampire: I have basic PPE
08:01 PM skunkworks: broke out the emco compac 5 pc to make the hub. still works
08:01 PM skunkworks: the monarch had a part in it to finish machining.. So I didn't want to disturb it.
08:19 PM Tom_L: ok i'm bored. gonna finish the kid's turners cube on my mill since he can't go to the vo'tech
08:19 PM Tom_L: luckily he brought the blueprint home
08:36 PM jymmmm: jthornton: Hey, I got your balloon chicken... https://youtu.be/JOApC-M9VmI?t=10
09:08 PM pink_vampire: any idea how to remove zinc coating from a bolt?
09:08 PM pink_vampire: I want to blue it
09:15 PM Rab: pink_vampire, https://www.practicalmachinist.com/vb/general-archive/zinc-plating-removal-any-easy-method-86057/
09:20 PM Thorhian: I was thinking of using this BLDC motor to drive my spindle. Any thoughts? https://www.amazon.com/BestEquip-Electric-Brushless-Controller-Throttle/dp/B07CCNPW6G?ref_=fsclp_pl_dp_11
09:23 PM Rab: Thorhian, looks like a beast as small BLDCs go. But two things: 1) you'll need a 1800W (derated) 48V power supply, 2) RPM might be rather low, unless you see a spec stating otherwise.
09:24 PM Thorhian: The spindle I'm using only handles 8000 max (supposedly). I can probably use some hearing to change the output RPM. Power supply would be a problem lol.
09:25 PM Thorhian: gearing*
09:27 PM Rab: Thorhian, I think I mentioned a DC treadmill motor the other day, and I'm totally serious. This is a not very good photo of my drill press conversion: http://reboots.g-cipher.net/8ball/image/IMG_0513.JPG
09:29 PM Thorhian: Is that the DC motor in the back feeding via belt?
09:29 PM Rab: Claimed 1HP on the nameplate, the controller accepts a simple PWM input and with the pulley arrangement it goes from 0 RPM to something stupid like 5000RPM. And it was free! Treadmill attached.
09:29 PM Rab: Yeah...sorry I don't have a pic from a better angle. There's a box on the other side for the motor controller.
09:30 PM Thorhian: What's the specs?
09:30 PM Rab: Anyway it's a common conversion for hobby machine tools, light lathes etc. Just google it.
09:31 PM Thorhian: Huh, if I could get my hands on one that would be great.
09:31 PM Rab: 90VDC, 1HP I think. Made by Leeson. I can't see the nameplate.
09:31 PM Rab: (120VAC input to the controller)
09:31 PM Thorhian: Ah so standard US AC input.
09:33 PM Rab: Better pic: http://reboots.g-cipher.net/cream.jpg
09:36 PM Thorhian: Now I just have to find one :/
09:36 PM Rab: It doesn't have much torque at very low RPMs, although the controller has an adjustable torque setting, which makes it very handy for pseudo-rigid tapping. I dial it down all the way, then up until it just starts to cut.
09:36 PM Rab: Thorhian, check craigslist, fecesbook free stuff, etc.
09:36 PM Thorhian: Yep
09:37 PM Rab: Although indoor exercise equipment is in great demand at the moment. :P
09:37 PM Thorhian: XD
09:38 PM Rab: I have another free treadmill motor that's a lot newer and smaller, but I think it's rated for either 1.5 or 2HP.
09:39 PM Thorhian: I just wish single phase AC motors didn't suck. I already have a few of those.
09:39 PM Thorhian: Also, 1.5HP would be fine as well.
09:40 PM Rab: They are great for what they are. I have one on my manual mill. I don't mind changing pulleys now and then.
09:41 PM Thorhian: I might just have to use one until I find something better.
09:41 PM Rab: But you may be able to find a three-phase motor through craigslist etc, from someone who bought an old 3-phase machine tool and did a motor conversion for residential power. Then you just need a VFD.
09:44 PM Thorhian: Would you have any tips for mounting a motor if it isn't integrated to the spindle? The only way I can think of is to the side of the z-axis assembly.
09:45 PM Rab: Looks like that scooter motor is probably 4800RPM, based on this: https://www.electricscooterparts.com/motors-my1020.html
09:46 PM Rab: Side, belted to the spindle? Seems reasonable to me.
09:46 PM Thorhian: Mounting it like on your drill press wouldn't be doable since the Z column would be in the way. I'm just worried about unbalanced weight. Maybe I'm just being paranoid lol?
09:48 PM Rab: If your linear bearings are serious, I don't think it's a problem.
09:49 PM pink_vampire: same bolt, I didn't want to use the modern zinc plated bolt as-is on 1972 lathe, so I file the grade marks, remove the zinc plating, and blue it, https://i.imgur.com/93KgvHj.png
09:49 PM Rab: That's an advantage of the BLDC: it's relatively small and light.
09:50 PM skunkworks: pink_vampire: cool. that is taking it to the next level :)
09:50 PM Thorhian: I'm guessing the treadmill motor isn't brushless hence the size lol?
09:50 PM Rab: I think it's brushed DC, yes.
09:54 PM skunkworks: I would do 3ph with vfd..
