12:09 AM voltagex[m]: <_unreal_ "what the hell? just got on aliex"> good luck!
01:56 AM Deejay: moin
05:17 AM JT-Cave: morning
06:01 AM TurBoss: morning
06:01 AM XXCoder: heys
06:02 AM TurBoss: hello, XXCoder
06:02 AM XXCoder: whats up
06:02 AM TurBoss: not much
06:02 AM TurBoss: i'm just downloading linuxcnc for the pi
06:12 AM TurBoss: too slow :D
06:14 AM XXCoder: lol fun
06:35 AM * JT-Cave thinks he's awake enough to start coding
06:41 AM TurBoss: took a look at paraport
06:41 AM TurBoss: looking great
06:42 AM JT-Cave: thanks
06:42 AM XXCoder: nice
07:18 AM solarwind: JT-Cave what are you working on?
07:19 AM JT-Cave: parallel port configuration tool for linuxcnc
07:20 AM solarwind: JT-Cave GUI based or command line?
07:21 AM JT-Cave: https://gnipsel.com/mesa/paraport/install.html
07:23 AM solarwind: JT-Cave I would love to contribute, is it on github or similar?
07:23 AM JT-Cave: https://github.com/jethornton/paraport
07:24 AM solarwind: Nice, thanks
07:24 AM JT-Cave: yw
07:28 AM solarwind: I actually created several patches. I haven't submitted merge requests for them yet.
07:28 AM JT-Cave: the repo is not current as I'm working on it now
07:28 AM solarwind: I meant for the mainline linuxcnc repository
07:28 AM JT-Cave: ok
07:42 AM solarwind: miss0r2 I think I recognize your name. Were you on the original reprap channel a couple of years ago?
07:43 AM solarwind: It was either you, flyback, drdoc, or enleth who pointed me here many moons ago. I can't remember
08:18 AM flyback: I been here like a year
08:18 AM flyback: biting canucks
08:19 AM flyback: I have known Tom_itx for like 20 yrs
08:20 AM flyback: I don't remember if I bougth you here or not sorry
08:24 AM _unreal_: flyback, when are you going to get your self a cnc machine
08:25 AM flyback: when I get my own house and probably not then either cause it's looking like I am going to end up with a house with no basement :(
08:25 AM flyback: unless I put it in a shed
08:26 AM _unreal_: heh
08:26 AM _unreal_: my cnc is in my home no issue
08:27 AM _unreal_: pick a room pick a corner
08:27 AM _unreal_: does not matter
08:27 AM _unreal_: if you have your own place who cares
08:27 AM flyback: it's a going to be a rented home so I can't just tear shit up
08:27 AM flyback: also not going to have any room as it is
08:27 AM flyback: :/
08:28 AM _unreal_: LOL
08:28 AM _unreal_: my cnc is in my bed room
08:28 AM _unreal_: its small
08:28 AM _unreal_: small work area
08:28 AM _unreal_: 7x12" wok area
08:28 AM _unreal_: does not take anything to make an enclosure if needed
08:28 AM _unreal_: simple dust collection
08:29 AM _unreal_: my DIY dust collection I now built is a HUGE improvement over what I had before and its a fraction of the noise
08:29 AM flyback: ok we will see how things go :)
08:29 AM _unreal_: as long as I'm not milling metal
08:29 AM _unreal_: its not Painfully loud
08:30 AM _unreal_: aluminum is painful
08:30 AM _unreal_: but I have no lost chips because my dust collection captures all of it
08:30 AM _unreal_: I get no dust because my system catpures it
08:30 AM _unreal_: so if I'm milling PCB's to FRP even I dont get any dust in the room
08:31 AM _unreal_: I dont have an enclosure though so its loud when its loud.
08:33 AM * CloudEvil ponders things that are quiet when they are loud.
08:33 AM CloudEvil: Deafening silence?
08:34 AM flyback: if my data recovery project phase #1 gets done soon
08:34 AM flyback: then I can start to think about other projects
08:35 AM flyback: phase 1 is just getting the bits ff old media into a nas
08:35 AM flyback: and throwing out 200 out old hd's
08:35 AM flyback: not even looking at the data yet
08:35 AM flyback: just getting it into new media and backed up
08:38 AM flyback: nothing is more important to me than this project
08:44 AM JT-Cave: Sounds of Silence Simon & Garfunkel
08:57 AM Tom_L: good one
09:02 AM _unreal_: hum
09:03 AM _unreal_: wishing wishing for a bit that I can not find
09:03 AM _unreal_: would love to have a 1/16th up cut with at least 12mm of flute
09:03 AM _unreal_: cant seem to find
09:03 AM _unreal_: only tapered
09:03 AM _unreal_: and I need straight
09:09 AM CloudEvil: 8:1 is going to be pretty fragile
09:09 AM _unreal_: yep
09:09 AM Tom_L: https://www.harveytool.com/products/tool-details-938962
09:09 AM _unreal_: but only looking at milling HDPE
09:09 AM CloudEvil: I assume you can't simply tilt the cutter
09:10 AM _unreal_: $40 a bit OUCH
09:10 AM Tom_L: but you said you couldn't find one :)
09:11 AM * CloudEvil wishes reversing the spindle worked.
09:17 AM _unreal_: playing with keyshot
09:17 AM _unreal_: man this software EATS some CPU
09:17 AM Tom_L: CloudEvil, most cutters that size are going to have a larger shank
09:17 AM _unreal_: free install IF you have the link
09:17 AM _unreal_: https://download.keyshot.com/keyshot9/keyshot_win64_9.3.14.exe
09:18 AM hazzy[m]: unreal: it does give a nice results with minimal effort
09:18 AM _unreal_: only get the link IF you have expensive cad software LOL love how they do that
09:18 AM _unreal_: hazzy[m], ?
09:20 AM Tom_L: looks like a marketing tool
09:23 AM _unreal_: graphics rendering from CAD in general
09:24 AM _unreal_: I'm designing a recycle coaster right now
09:24 AM _unreal_: to make from old poly cutting boards
09:24 AM _unreal_: sell on etsy
09:53 AM solarwind: Hey guys, I want an easy way to drill/punch out holes in sheet metal. Thickness is the standard thickness of surface mount electrical boxes, the kind that switches and sockets are mounted to
09:53 AM solarwind: Diameter of hole is 15/16"
09:53 AM solarwind: I have an annular cutter of that size which should work just fine, but I can't help but think a press is the way to go
09:54 AM solarwind: I can machine a punch of the appropriate diameter, but what would be the backing material once the punch presses through the sheet metal?
09:54 AM solarwind: A block of wood? Mild steel?
09:54 AM Tom_L: https://www.amazon.com/Greenlee-730BB-15-16-Standard-Knockout/dp/B002NQX038
09:54 AM Tom_L: make one
09:55 AM solarwind: Tom_L incredible. I did not expect that to exist
09:55 AM Rab: solarwind, a hardened die.
09:55 AM solarwind: But yes I don't mind making one on the lathe. I'd have to make it out of annealed tool steel of some kind. Not sure what alloy to use. M2? D2? A2?
09:56 AM CloudEvil: solarwind: step drill?
09:56 AM CloudEvil: For 15/16, it's pretty much teh very easiest way
09:56 AM solarwind: CloudEvil wow didn't consider that either. Brain clearly dead today
09:56 AM Tom_L: https://www.amazon.com/Allpax-AX1812-Arch-Punch-16-Inch/dp/B00SORUWAY
09:56 AM Rab: solarwind, how many cycles? Just a few, or production?
09:56 AM Tom_L: for soft materials
09:56 AM solarwind: Rab about 30 small plates, so < 100 holes
09:57 AM solarwind: Material is nothing harder than mild steel
09:57 AM solarwind: This is for mounting the Neutrick PowerCon sockets
09:59 AM Tom_L: a stepdrill that size would likely cost nearly as much as that punch
10:00 AM solarwind: https://www.aliexpress.com/item/32853645650.html?spm=a2g0o.placeorder.0.0.1de0321ejyHEYe&mp=1
10:00 AM Rab: Yeah, you'll want something harder than mild steel for the punch and die, otherwise they'll deform quickly. For 100 holes I would look into the Greenlee or similar knockout punches. I don't know that those will be faster than your annular cutter in a mag drill, though.
10:00 AM Tom_L: https://www.homedepot.com/p/Milwaukee-SHOCKWAVE-Impact-Duty-Titanium-Step-Bit-Kit-3-Piece-48-89-9257/306731210
10:01 AM Tom_L: but those are designed for sheet metal as well
10:01 AM Rab: Step drill seems like a lot more work than an annular cutter, esp for 100 holes.
10:01 AM solarwind: That's the set I bought and I'm extremely pleased with the quality. It works out to $3/pair
10:01 AM solarwind: Yeah I already have an HSS annular cutter the exact size
10:01 AM solarwind: So I guess I'll stick with that
10:02 AM Rab: Carbide tipped, or just like a hole saw?
10:02 AM solarwind: It's an actual annular cutter, M2 HSS
10:02 AM solarwind: Not like a hole saw
10:02 AM solarwind: It has a weldon shank
10:02 AM Rab: Yeah, sounds like a winner.
10:03 AM solarwind: There are carbide tipped options, but they're far more expensive and I couldn't justify that.
10:03 AM solarwind: So I bought this kit: https://accusizetools.com/collections/annular-cutters/products/1-depth-cutter-8pcs-hss-annular-cutters-set-9-16-5-8-11-16-13-16-15-16-1-1-16-hcs3-0000
10:03 AM Rab: Lower speed and cutting oil advised, for HSS.
10:03 AM solarwind: Absolutely.
10:03 AM Rab: Will you be using a mag drill/drill press, or a handheld tool?
10:04 AM solarwind: My bridgeport mill
10:04 AM Tom_L: many more than what you have i'd go the punch route
10:04 AM solarwind: Tom_L yeah that makes sense. It's not a production run
10:05 AM solarwind: I'll just use a block of wood or plastic or the least abrasive substance to fixture the workpiece
10:06 AM solarwind: I think wood is somewhat abrasive? I know almost harmless for 100 holes, but if I can avoid it, I'd rather stick with a block of plastic or something
10:07 AM Tom_L: secure the waste board so the hole is repeatable
10:08 AM solarwind: That's the plan. The face plates are all identical
10:08 AM solarwind: I might even be able to get away with stacking them 10 at a time
10:08 AM Rab: solarwind, since you're using a mill, I'd start by drilling into a fixtured scrap steel plate, and using that as a backing plate. The holes in the sheet will be nice and clean.
10:09 AM solarwind: The face plates will be like this: https://homedepot.scene7.com/is/image/homedepotcanada/p_1000106244.jpg?op_sharpen=1
10:09 AM solarwind: Should be easily stackable
10:10 AM solarwind: Rab good idea. Since these things have mounting holes already, it would be easy to index them all on their mounting hole
10:10 AM Rab: Could be, yeah. You might even be able to rig up some kind of stepped/angled vise jaws to clamp them down when tightened.
10:10 AM solarwind: All great ideas. Have a standard Kurt vise on the mill
10:11 AM solarwind: And heading out to continue scrapping operation so I'll have plenty of scrap steel to make jaws and fixtures and such
10:12 AM solarwind: Do I need a special weldon shank holder or will a 3/4" collet work just fine?
10:13 AM solarwind: I have R8 and ER32
10:25 AM _unreal_: voltagex[m], I have had no issues getting stuff from ali
10:27 AM _unreal_: arch hold punch. is that for a tool? I assume its not for WACKING with a hammer
10:36 AM JavaBean: a metal "punch out" usually doesn't use a hammer. its normally "forced through" via one hell of a screw or hydrallically
10:42 AM CloudEvil: Hammer tends to run the big risk that the punch and die hit as the thing misaligns due to the force of the hammer
10:43 AM Tom_L: i posted that as an example for softer material ie leather etc
11:23 AM _unreal_: I have to use hammer punches all the time making gaskets for boats
11:24 AM _unreal_: boona gasket
11:36 AM _unreal_: any one making anything today?
11:46 AM flyback: fixed up my data recovery box #1
11:46 AM flyback: soldered on new molex connectors so I could install the origional psu
11:47 AM flyback: fixed an issue with loose connection to +5vsb causing issues with bmc and new drac card
11:47 AM flyback: installed a drac c ard I got used for $20
11:47 AM flyback: had to put firefox 2.0 in a vm and setup a old 32 bit win7 laptop to use the drac card but worth it
11:47 AM flyback: avoids having to put a head on a box buried in a cabinet
11:48 AM flyback: modifed the front fan I added to keep the raid drives cool
11:48 AM flyback: turned out I didn't need to run it full blast to keep them around 33C max temp which is fine for a hd
11:48 AM flyback: min speed was fine and is not hearable vs max blast which sounds like hair dryer
11:48 AM flyback: also canucked up 2 fingers in the process but they are mostly healed now
11:49 AM flyback: once I get most of my data recovery project transfered to the nas and backed up finally
11:49 AM flyback: I can start to toss boxes of old hard drives taking up tons of my space
11:49 AM flyback: and start to work on other things like learning to code mcu's and make things
12:06 PM _unreal_: hehe fusion is stragggaalling with this tool path... generation is a bit slow LOL

01:09 PM perry_j1987: wish i could wear shorts in the shop
01:09 PM perry_j1987: not a fan of chips getting in my socks though
01:14 PM CloudEvil: Don't wear socks.
01:23 PM roycroft: wrap duct tape around the top of your socks
01:24 PM * roycroft wears shorts in the shop all the time when he's woodworking, but wears trousers when metalworking
01:33 PM roycroft: are you about perchance, jt-wherever?
01:37 PM JT-Shop: yup
01:39 PM JT-Shop: in and out here and the other shop
01:39 PM perry_j1987: ugh the power here sucks
01:39 PM perry_j1987: guys in a neighboring shop got a huge compressor running and its dropping voltage to the whole building to 104v
01:40 PM CloudEvil: Not just screwing with the neutral?
01:41 PM perry_j1987: i dont trust how any of the building is wired lol
01:41 PM perry_j1987: one of the outlets in mine was wrongly wired
01:41 PM perry_j1987: got nice tingling sensation on anything plugged into it at first
01:41 PM roycroft: that's not your neighbor's fault
01:42 PM perry_j1987: all the units are daisy chained off eachother here
01:42 PM perry_j1987: im at the end of a line of crap lol
02:01 PM roycroft: jt-shop: you said the other day that you don't think you've seen beechwood
02:01 PM roycroft: my kumiko jigs have beechwood bodies
02:02 PM roycroft: roycroft.us/Kumiko-Jigs
02:07 PM JT-Shop: the insert is beechwood on the first one?
02:07 PM Tom_L: yup that looks like beech
02:07 PM roycroft: the sliders are walnut
02:08 PM roycroft: the bodies are beech
02:08 PM enleth: perry_j1987: unless the landlord is a hopeless dolt, there has to be a way to improve this for you
02:09 PM roycroft: it may not be the landlord's problem
02:09 PM perry_j1987: enleth im looking for a better shop situation
02:09 PM roycroft: it may be that the power utility just don't have a big enough transformer at the site
02:09 PM perry_j1987: its also just so darn cheap rent here lol
02:10 PM perry_j1987: im waiting on buddy to give me back one of my golf cart batteries he borrowed so i can try running off inverter
02:10 PM JT-Shop: roycroft, what does this jig do? https://roycroft.us/Kumiko-Jigs/Disc-Sander-Kumiko-Jigs-3.jpeg
02:10 PM perry_j1987: and just use a 10amp car charger to top off the battery bank heh
02:10 PM roycroft: jt-shop: i need to make hundreds of short pieces of wood with precise angles on both ends
02:11 PM JT-Shop: ah that makes sense
02:11 PM roycroft: i use the sliders to set the length
02:11 PM roycroft: and the jig indexes against the rail on the base
02:11 PM JT-Shop: I guess that's about the only way to shape a tiny part
02:11 PM roycroft: https://roycroft.us/Kumiko-Jigs/Block-Plane-Kumiko-Jigs.jpeg
02:11 PM roycroft: i've been using those for a couple years
02:11 PM roycroft: i set the length the same way
02:12 PM roycroft: but i have to use a block plane or chisel to cut the miters
02:12 PM roycroft: which is rather time-consuming
02:12 PM roycroft: the disc sander speeds the process up by an order of magnitude or so
02:12 PM * JT-Shop heads back to cabinet building
02:13 PM roycroft: anyway, that's what beech looks like, and since i'm sure you've seen it many times before, now you'll recognise it when you see it
02:15 PM unterhausen: roycroft, those fixtures are nice. I have something that's a similar idea for cutting the small miters for frame/panel
02:16 PM unterhausen: *not made of beech
02:23 PM roycroft: thanks, they work really well
02:24 PM roycroft: i have a bunch of beech laying around - it's not necessary, but it's a very stable wood, so it's good for jigs and tools and the like
02:25 PM roycroft: i could make the jigs out of scrap 2x4s and they would work fine, for a while at least
02:26 PM roycroft: for one off stuff i use a shooting board with angle plates, but when i need to make hundreds of pieces the exact same length, the jigs are the only reasonable way to do it
02:28 PM Tom_L: i got a chunk of hard maple for similar stuff
02:28 PM Tom_L: they are ~about equal for that
02:29 PM roycroft: hard maple is excellent for making jigs
02:29 PM roycroft: around here beech is a lot cheaper than hard maple
02:29 PM Tom_L: i got this as scrap from a mill shop
02:30 PM roycroft: which seems odd, because hard maple comes from eastern us or canada, but the beech we get is european
02:30 PM roycroft: one would think that shipping it across the ocean would add significant cost
02:31 PM roycroft: bigleaf maple is cheap here, as it's local, but it's not nearly as hard as sugar maple
02:33 PM roycroft: iirc, 8/4 steamed european beech is ~$4.00/bf, and 8/4 hard maple about $8.50/bf
02:33 PM roycroft: but free scrap is a lot cheaper than $4.00/bf
02:55 PM _unreal_: why does fusion have to be such a pain in the ass
03:33 PM * JT-Shop forgot to square up one end on the top and bottom before setting up for the dado... I hope I can get the dado setup the same
04:24 PM {HD}: I thought I had see a ton of cheap loc-line on aliexpress but now I cannot find anything. What do they call loc-line in china?
04:26 PM XXCoder: {HD}: pemenia hose something
04:26 PM XXCoder: cant spell it at all
04:27 PM {HD}: XXCoder: what are you doing??! when I typed in "pemenia" to aliexpress I get a "You must be at least 18 years of age to enter this section of AliExpress"
04:27 PM {HD}: I am not clicking on that.
04:27 PM XXCoder: lol
04:29 PM XXCoder: coolant spray line works
04:29 PM XXCoder: https://www.aliexpress.com/item/32843226702.html
04:33 PM {HD}: XXCoder: Yea, maybe I can follow related items to what I really want. I want some of the beefy 3/4" stuff.
04:38 PM Rab: I see multiple common sizes, but 1/2" seems to be the biggest.
04:39 PM Rab: Considered buying it from Loc-Line? Their prices aren't crazy, as industrial products go. https://www.loc-line.com/product/60513-34-hose-assembly-kit/
04:39 PM _unreal_: JT-Shop, after messing up the dado do you feel like a DODO?
04:40 PM _unreal_: doedoe?
04:40 PM _unreal_: o.m.g... fusion is still post processing this milling job
04:42 PM {HD}: I guess 5' for $45 isn't that bad...
04:42 PM {HD}: I'd like to pay like $4.99 though
04:44 PM Tom_L: how long?
04:44 PM {HD}: 2-3' would be more than enough...

04:53 PM XXCoder: why isnt 1/2 enough? why not 2 of em?
04:53 PM {HD}: Well I am actually going to use it to mount the control surface onto. To the side of my machine. In my tests with different things the 3/4" was stiff enough to hold it up.
04:54 PM XXCoder: ahh different user case than i was thinking of
04:54 PM XXCoder: steel wound tubes dont work for you?
04:55 PM XXCoder: though maybe less locking in place hmm
05:16 PM JT-Shop: XXCoder, any luck on the job front?
05:16 PM XXCoder: dunno, not monday yet
05:17 PM JT-Shop: if you were in Australia it might be Monday
05:17 PM XXCoder: :)
05:28 PM _unreal_: that was odd
05:28 PM _unreal_: hex chat crashed
05:42 PM _unreal_: ok its milling
05:48 PM _unreal_: so who's milling?
05:55 PM {HD}: loc-line on amazon is under "pet supplies" why is that?
05:56 PM Tom_L: fish tanks
05:59 PM Tom_L: https://www.bulkreefsupply.com/loc-line-modular-hose-segments.html
06:08 PM Centurion_Dan1 is now known as Centurion_Dan
06:11 PM _unreal_: silent
06:11 PM _unreal_: anyone milling anything?

06:58 PM {HD}: fish tanks! I would have never guessed...
10:23 PM solarwind: Just got back from day one of the scrapping operation. You all had me convinced I'd be eating through reciprocating saw blades.
10:24 PM perry_j1987: well... its official i have a lathe testbar enroute now
10:24 PM solarwind: I brought my oxy acetylene torch, angle grinder, as well as reciprocating saw
10:24 PM solarwind: I used all three "equally" and a single dewalt blade, 14 TPI lasted the whole day and still sharp
10:25 PM solarwind: I'm incredibly impressed with how well it worked. I used cutting oil and kept it cool so that played a huge role. And it was fast and effective.
10:25 PM solarwind: Not sure if I'm impressed because I had low expectations going in, or because its performance was indeed simply impressive
10:26 PM solarwind: I made sure not to saw through anything harder than mild steel though. So no ball bearings, etc. I used the torch for that and it worked just fine
10:27 PM solarwind: I don't think I'll ever have to buy steel for the rest of my life. It's pretty much a take whatever you can cut and carry kind of thing. There was solid steel shaft about 10cm in diameter, 2m long but I had nothing to cut through that. Need a bigger nozzle on the torch
10:42 PM JavaBean: you will never have enough material. the material you have the most of will not be the kind of material you need for a project
10:46 PM perry_j1987: https://www.youtube.com/watch?v=2v0qTPPgjig
10:46 PM perry_j1987: not sure why im watching this but...
10:46 PM perry_j1987: who knew... hotglue for workholding lol
10:47 PM JavaBean: its all good, until you break the part trying to get it off the "workholding"
