04:08 AM Tom_L: morning
05:46 AM JT-Cave: morning
05:46 AM XXCoder: heys
11:48 AM solarwind: Hi guys, my friend is asking me to help him scrap a whole bunch of his pallet making machinery which consists of hollow structural steel. There's a huge warehouse and I get to keep whatever I want. The rest goes to the scrap yard
11:48 AM solarwind: He has oxy acetylene equipment on site and I have a plasma cutter, angle grinder, reciprocating saw
11:48 AM CloudEvil: nice
11:48 AM solarwind: Accuracy of cut, quality of cut does not matter
11:48 AM solarwind: Which would be the easiest and fastest way to cut up metal
11:49 AM solarwind: Essentially, the goal is to cut up the machinery into manageable pieces, load it onto a truck, and take it to the scrap yard. I can set aside any pieces I want
11:49 AM CloudEvil: Any of the above depending on the sort of material.
11:50 AM solarwind: 99% mild steel like hollow square and round tube
11:50 AM solarwind: some solid shafts
11:50 AM CloudEvil: Plasma and oxy/ac can be really awkward to cut square and round tube as they can't get to the other side easily in constrianed places.
11:54 AM Tom_L: same with other tools as well really
11:54 AM roycroft: a skilled person with the oxy-acetylene torch would probably be the fastest
11:54 AM Tom_L: the scrap here uses acetylene torch
11:55 AM Tom_L: a big one
11:56 AM roycroft: the plasma cutter will be slower than oxy-acetylene, requires a bit more control, but most importantly, it's tethered
11:57 AM roycroft: and if you're cutting up big machinery you'll have to move it around, which means moving the power around
11:57 AM solarwind: CloudEvil that's good point about not getting to the other side. Reciprocating saw would be quite fast for hollow tube in that case
11:57 AM roycroft: the oxy-acetylene torch is self-contained
11:57 AM solarwind: roycroft can you explain the "tethered" part?
11:57 AM roycroft: it has a power cord
11:58 AM roycroft: a reciprocating saw will be painfully slow for this
11:58 AM Tom_L: i dare say the saw would be alot slower
11:58 AM solarwind: Oh right. In his warehouse, there are appropriate power outlets for this everywhere, so that won't be a problem
11:58 AM Tom_L: whatever you do, don't burn the place down
11:58 AM CloudEvil: Also, reciprocating saws go blunt deperssingly fast in other than ideal conditions.
11:58 AM roycroft: and don't put your eye out
11:59 AM solarwind: CloudEvil I have carbide tipped metal cutting blades
11:59 AM CloudEvil: understand the machine loading and framing before dissasembly.
11:59 AM CloudEvil: solarwind: you'd hope that would help.
11:59 AM solarwind: I've used it in the past, didn't have an issue with it. I'll bring some cutting fluid for those hollow tubes
12:00 PM CloudEvil: Oil can help a fair bit.
12:00 PM CloudEvil: make sure you don't get the blade pinched.
12:00 PM roycroft: it sounds like you've decided on the thing we all recommend not using, and that you decided before you asked us
12:00 PM Tom_L: :)
12:00 PM solarwind: No, I'm going to be bringing all tools
12:01 PM * roycroft wondeers if there's a point to this discussion
12:01 PM Tom_L: roycroft, only if you poke your eye
12:01 PM solarwind: Just wondering what your thoughts are on the fastest. So sounds like oxy acetylene for most parts
12:01 PM roycroft: i have safety glasses, and i alwasy wear them, because they are prescription glasses, and i cannot see without them
12:02 PM solarwind: Yes PPE goes without saying. I have asthma, so I can't not wear anything except my PAPR helmet
12:02 PM solarwind: can't wear anything except*
12:02 PM Tom_L: so using abrasives would not be the best either then ehh?
12:03 PM solarwind: Well the PAPR helmet protects me against abrasive dust too
12:03 PM roycroft: a skilled person with a torch will cut circles around a grinder grunt
12:04 PM solarwind: I'm not an artisan by any means, but these cuts are purely for demolition purposes
12:04 PM Tom_L: so rent some jaws of life and be done
12:05 PM solarwind: Tom_L is that a serious suggestion? I can propose that to them
12:05 PM roycroft: i'm assuming hacking is the expected outcome, not clean cuts
12:05 PM Tom_L: it would be quick
12:05 PM roycroft: the skill refers to being able to cut quickly here, not neatly
12:05 PM solarwind: Clean cuts are not the objective. It's simply to make the scrapping operation easier by cutting the machines into smaller pieces
12:05 PM roycroft: although the two go hand in hand
12:05 PM roycroft: it's more work to make a sloppy cut than a neat, clean one
12:07 PM roycroft: of course, we have no sense of the size or thickness of the tubing
12:07 PM roycroft: i'm assuming stuff in the ballpark of 2" tubing that's 0.065" thick
12:07 PM solarwind: On average, assume 2" nominal with 1/4" wall thickness
12:08 PM roycroft: ok, so a lot thicker than i thought
12:08 PM roycroft: all the more reason to use a torch
12:08 PM solarwind: Err, 1/4" max.
12:08 PM solarwind: Most a lot thinner
12:08 PM Tom_L: pinchers attached to wrecking equiment don't really care how heavy it is
12:08 PM roycroft: he does want to salvage some of it for personal use
12:08 PM solarwind: These are huge pallet making machines
12:08 PM solarwind: SO they're not rigid like mills or routers
12:09 PM solarwind: They're just physically large
12:09 PM solarwind: Which means nice long stretches of metal in pristine condition
12:09 PM roycroft: 1/4" thick tubing is going to take you a week to cut through with a sawzall
12:10 PM roycroft: and you'll be changing blades every few cuts, at most
12:10 PM roycroft: er, at least
12:10 PM solarwind: Alright, I'll take your word for it.
12:10 PM roycroft: the only question is: do you have enough experience with an oxy-acetylene torch to set it up properly and use it properly?
12:11 PM roycroft: if you're moderately skilled with it it will be the fastest method by far
12:11 PM roycroft: if you've never done it before it might be the slowest
12:11 PM solarwind: Yes, I follow the safety procedures strictly, multiple flashback arresters.
12:12 PM solarwind: I've used it like 3 or 4 times before
12:12 PM roycroft: if you've cut with it thousands of times you'll be able to make clean, dead square cuts as fast as you can use the torch head
12:12 PM roycroft: er, move the torch head
12:13 PM roycroft: so you're not quite moderately skilled with it
12:13 PM solarwind: This is a good opportunity to practice
12:13 PM solarwind: I've used oxy acetylene equipment multiple times for heating/welding/brazing
12:13 PM Tom_L: if you screw it up, you can always weld it back on and recut it :)
12:13 PM roycroft: but if you succeeded before, you'll get the hang of it fairly quickly, and it will probably still be the fastest method
12:13 PM solarwind: This being a scrapping operation, there's really no way to mess it up
12:14 PM roycroft: sure there is
12:14 PM roycroft: you could burn the warehouse down or put your eye out
12:14 PM roycroft: or both
12:14 PM Tom_L: slag in flipflop
12:14 PM solarwind: I'll keep that in mind
12:15 PM roycroft: it's 10 o'clock already
12:15 PM Tom_L: can't be
12:15 PM * roycroft is having a lazy saturday morning
12:15 PM Tom_L: i just had lunch
12:16 PM roycroft: i have to finish the blackberry job this morning, and am having a hard time getting motivated
12:16 PM roycroft: there's only about an hour's work left, and then hauling it off
12:19 PM roycroft: yikes
12:20 PM roycroft: 35 today - it's gonna be hit
12:20 PM roycroft: hot
12:20 PM * roycroft should get his outdoor chores done asap
12:22 PM solarwind: Tom_L I can't tell, was the jaws suggestion a joke or were you being serious?
12:22 PM solarwind: Because if it's a viable option, I'll bring it up to the owner of the warehouse if it can speed up the operation
12:22 PM solarwind: He has hydraulic power packs on site too
12:36 PM * JT-Shop gives up and digs out his 3/4" oak plywood and tries to figure out how to make a rolling cabinet with the least plywood
12:37 PM JT-Shop: hmm I have some 1/8" ply for the back and crap plywood for top and bottom
12:38 PM solarwind: Someone told me lumber prices are going to drop to 30% of what they were recently. Is this true?
12:41 PM JT-Shop: timber price has dropped 60% last time I looked
12:44 PM solarwind: Oh so it has already begun? Time to start buying I suppose
12:50 PM roycroft: yes, it began a few weeks ago
12:51 PM roycroft: sheet goods are lagging behind dimensional lumber, but it's all dropping
01:19 PM JT-Shop: https://www.nasdaq.com/market-activity/commodities/lbs
01:21 PM -!- #linuxcnc mode set to +o by ChanServ
01:22 PM -!- #linuxcnc mode set to -o by ChanServ
01:55 PM CloudEvil: 300 to 1500 is some range in a year
03:21 PM CaptHindsight[m]: which wanted features for FFF/FDM printers are missing from LCNC?
03:28 PM Rab: solarwind, I think fastest cuts in mild steel tubing would be a circular saw or chop saw designed for steel.
03:30 PM Rab: I use a regular chop saw with a carbide-tipped blade for aluminum, I tried it on steel once and while I don't remember exactly what happened, it seemed like something not to repeat.
03:42 PM CaptHindsight[m]: for one it dulls the blade quickly
03:43 PM CaptHindsight[m]: I was too lazy and used my wonderful blade for aluminum on a couple cuts of DIN rail and it's never been the same.
03:52 PM roycroft: capthindsight: he's dismantling large machinery in situ
03:53 PM CaptHindsight[m]: yeah, saw
03:53 PM CaptHindsight[m]: <rimshot?
03:53 PM JT-Shop: roycroft, I'm toying with making the cabinet sides with rail/stile construction
03:53 PM roycroft: i would avoid a circular saw just because of the noise alone :)
03:53 PM roycroft: but it might prove unwieldy
03:54 PM roycroft: nice, jt-shp
03:54 PM roycroft: i've done that many times
03:54 PM JT-Shop: ok, just checking before I start...
03:54 PM roycroft: i've been doing european style cabinets for the most part lately
03:54 PM CaptHindsight[m]: if he could rent this https://www.youtube.com/watch?v=DZvVxkAVLfE&list=PL3f0O-D3NXi-3NVXeaDO07uUzqwVkREsY
03:54 PM roycroft: frameless
03:54 PM roycroft: but i like panel cabinets
03:55 PM * roycroft just got back from recycling
03:55 PM CaptHindsight[m]: but he's on the right track to use a cutting torch
03:55 PM JT-Shop: the cabinet will be on castors so 20" wide, 24" deep and 24" tall
03:55 PM CaptHindsight[m]: vs corded plasma cutter
03:55 PM roycroft: i thought i would be done with the blackberries today, but that last patch was pretty dense, and i could not fit them all on the load
03:55 PM roycroft: are you going to use plywood for the panels?
03:56 PM JT-Shop: I have some 1/4" baltic birch left over
03:56 PM roycroft: a torch would be the fastest way to do the job, capthindsight
03:56 PM roycroft: assuming he knows how to use it
03:56 PM JT-Shop: or I could glue up some red oak that is wormy and knotty
03:56 PM CaptHindsight[m]: nah, explosives
03:56 PM roycroft: and he said he's done cutting with a torch before
03:57 PM Tom_L: shape charges
03:57 PM CaptHindsight[m]: yup
03:57 PM roycroft: if you want it to look nice, cut veneers out of the wormy oak and laminate them on the bb plywood
03:57 PM CaptHindsight[m]: thermite works well for tall buildings
03:57 PM Tom_L: usually
03:57 PM roycroft: he wants to scavange some of the materials
03:58 PM roycroft: otherwise i'd have suggested strategically placed explosives myself
03:58 PM JT-Shop: trying to decide on how many drawers to put in it
03:58 PM CaptHindsight[m]: was the thermite "found" on the twin towers steel beams ever confirmed or explained? I only saw the claims.
03:58 PM roycroft: there were a lot of claims
03:59 PM roycroft: the only things that were "found" were the two planes that crashed into the towers
03:59 PM CaptHindsight[m]: why I was wondering
04:00 PM CaptHindsight[m]: oh well, evidence destroyed, like kennedy, oops
04:00 PM CaptHindsight[m]: we'll never know
04:00 PM roycroft: if you believe anything else about the 9/11 attacks then you probably also believe that the covid-19 vaccines have tracking micorchips in them
04:00 PM roycroft: and that the 2020 election was rigged
04:00 PM CaptHindsight[m]: nah
04:01 PM CaptHindsight[m]: I can't even find original videos
04:01 PM roycroft: conspiracy theories used to at least be worthy of looking into to the point of disproving them
04:01 PM roycroft: now the theories are so crazy they just need to be dismissed immediately
04:02 PM CaptHindsight[m]: anything besides the official propaganda gets labelled as "conspiracy theory"
04:03 PM CaptHindsight[m]: and what is official changes based on who the officials are
04:03 PM roycroft: and lest you think that's partisan thinking on my part, i said those exact same words to my friends after the 2000 and 2004 elections when they claimed they were rigged for dubya
04:03 PM CaptHindsight[m]: easy to do with people that don't think
04:04 PM roycroft: i'm pretty good and sorting propoganda from truth, and very good at sorting coo coo bananas conspiracy theories from truth
04:05 PM CaptHindsight[m]: well whenever Kennedy's brain shows back up we can clear this up once and for all
04:05 PM roycroft: i believe in science, and one of the main reasons i believe in science is that science doesn't give a rat's arse if i believe in it or not
04:05 PM CaptHindsight[m]: Einstein's brain was in a jar for a few decades
04:06 PM Tom_L: did the jar get smarter?
04:06 PM CaptHindsight[m]: same for all those tower beams
04:06 PM CaptHindsight[m]: https://www.amazon.com/Driving-Mr-Albert-America-Einsteins/dp/038533303X
04:07 PM CaptHindsight[m]: fun read
04:08 PM roycroft: nixon's head in a jar is just as nasty as nixon was while he was alive
04:08 PM roycroft: i should assume that einstein's brain in a jar would be just as smart as when he was live
04:08 PM Rab: Supplemental off-topic content: https://www.youtube.com/watch?v=C7pTChMjKe8
04:10 PM roycroft: there is no wtc mystery
04:11 PM CaptHindsight[m]: not to you, understood
04:11 PM CaptHindsight[m]: what was the reason for the building not hit by the planes to implode and collapse?
04:11 PM roycroft: the reason all the conspiracy theories fall apart immediately is that for any of them to be valid, the bush/cheny administration would have to be competent enough to orchestrate a massive false flag attack that worked flawlessly, and all this just a few months after taking office, while they were still putting their administration together
04:12 PM CaptHindsight[m]: did they publish the findings on that 3rd building? I don't recall
04:13 PM roycroft: and keep in mind that because of the disputed election, they were months late even getting started with their administration - they could not begin to assemble a government until bush was sworn in, essentially
04:13 PM roycroft: while usually it starts happening in november
04:13 PM roycroft: i don't recall either
04:14 PM CaptHindsight[m]: yeah that incompetent administration that started that war in Afghanistan and Iraq?
04:14 PM roycroft: but when the two tallest buildings in the world are right next door to you, and they fall down, there's a good chance you will suffer severe damage as well
04:14 PM CaptHindsight[m]: ah
04:14 PM CaptHindsight[m]: thanks, so simple
04:14 PM roycroft: you mean the longest war in us history, that is ending in a stalemate at best?
04:14 PM CaptHindsight[m]: yeah, mission accomplished
04:15 PM roycroft: i turned the ac on in the garage shop when i got back from recycling
04:15 PM roycroft: when it cools down there a bit i'm going to to pull the motor off my milling machine and see if i can sort out what it is
04:15 PM CaptHindsight[m]: why I never go near cemeteries
04:16 PM XXCoder: those who belive in termites in towers tend to because they dont belive that steel melt under jet fire. but problem with that steel dont need to MELT. Just heated enough to lose strength
04:16 PM XXCoder: so the claim is based on supposition only.
04:16 PM CaptHindsight[m]: so steel gets softer when it gets hotter?
04:16 PM XXCoder: no evidence, no nothing. just supposition
04:17 PM XXCoder: above certain temperate yeah. which jet fuel fire can easily reacj
04:17 PM CaptHindsight[m]: ah, so simple
04:17 PM XXCoder: yeah. nothing complex.
04:18 PM CaptHindsight[m]: should have learned from Icarus
04:19 PM CaptHindsight[m]: but I think he was just a story vs fact
04:19 PM JT-Shop: roycroft, https://electronics.stackexchange.com/questions/101676/how-to-tell-whether-a-motor-is-an-ac-or-dc-motor
04:19 PM JT-Shop: #3 looks pretty informative
04:19 PM roycroft: thanks
04:20 PM roycroft: i'm hoping to find a plate on the motor that tells me what i need
04:20 PM JT-Shop: that would be best
04:20 PM roycroft: yes
04:21 PM roycroft: grizzly sell brushes for the motor, so i know it's brushed before i even start working on it
04:21 PM roycroft: it only takes about 5 seconds at most to determin brushed vs. brushless anyway
04:21 PM JT-Shop: that sounds like brushed dc to me
04:22 PM roycroft: so i was in the middle of a job when the machine failed
04:22 PM roycroft: which may be another reason to just replace the controller with a third-party one that's more compatible with linuxcnc
04:22 PM JT-Shop: I know that feeling the DRO board for the drum sander that went out last month is due to ship middle of next month
04:22 PM roycroft: that would let me avoid dismantling the machine to repair it
04:22 PM roycroft: i'm hoping not to have to touch the setup on the bed
04:23 PM roycroft: i don't mind moving the head up to remove the motor, but i don't want to touch x or y if i can help it
04:24 PM roycroft: i still want to put the machine stand on casters, but i'd rather wait until i finish this job before doing that
04:40 PM roycroft: well that was too easy
04:41 PM roycroft: i went to clear some space so i could pull the motor, and right on the side there is a sticker that says "dc 100v 0.8HP 4000rpm 6.5a"
04:41 PM JT-Shop: well there you go
04:44 PM roycroft: yeah
04:45 PM roycroft: i'm not sure, though, that i should trust a machine that gives up its secrets so easily
04:46 PM roycroft: https://www.aliexpress.com/i/32983131893.html
04:46 PM roycroft: that is the exact motor
04:46 PM roycroft: well, that's the 230v version
04:46 PM roycroft: but the same model

05:27 PM JT-Shop: saw stop cabinet carcass https://gnipsel.com/images/wood-working/saw-stop/Cabinet.JPG
05:27 PM JT-Shop: front drawers, back side shelves
05:29 PM CaptHindsight[m]: https://www.machinedesign.com/home/article/21830429/another-blow-for-wtc-conspiracy-theorists
05:30 PM XXCoder: "The Open Chemical Physics Journal" closed doors at 2014
05:31 PM XXCoder: seems they just accepted submissions
05:33 PM CaptHindsight[m]: yeah, how do you even get the evidence to verify?
05:35 PM Tom_L: somebody turned up the burners... 97F currently

05:36 PM CaptHindsight[m]: how can you not hear all those explosions?
05:36 PM XXCoder: is it unreal being ... unreal again?
05:37 PM CaptHindsight[m]: https://www.youtube.com/watch?v=1N50IjDB5Sk even louder here
06:53 PM Eric__: if the Red Cross cancels my donation appointment again, I'm going to believe there is a vast government conspiracy
07:00 PM Eric__ is now known as unterhausen
07:00 PM CaptHindsight[m]: how to separate conspiracy theories, from theories, conspiracies and non-conspiracy theories?
07:00 PM CaptHindsight[m]: did Bigfoot kill Kenddy?
07:05 PM roycroft: none of that matters anyway
07:05 PM roycroft: the burning question is: is nessie real?
07:06 PM roycroft: if we're going to talk about such theories, we should at least talk about ones that matter
07:09 PM CaptHindsight[m]: sure Nessie is real, but a sea monster in loch Ness?

07:49 PM ve7it: machining question.... has anyone on here ever tried to machine Neodymium Magnets? I need to bore a 17mm hole in a 70x20mm circular magnet
07:50 PM Tom_L: no but best of luck
07:51 PM ve7it: seems the chips will be a real problem
07:52 PM XXCoder: isnt tungsein carbide nonferric?
07:52 PM Tom_L: they're likely rather brittle
07:52 PM XXCoder: you probably need to have non-magnetic jaws nd etc so stuff dont stick to em?
07:52 PM XXCoder: and yeah brittle
07:55 PM ve7it: https://www.ebay.ca/itm/181629689679 something like this one... this seller looks like they may have some ideas
07:58 PM XXCoder: might be cast then molded
07:58 PM XXCoder: after all you heat up it in magnet field you want it to have and it gets set as it cools down
07:59 PM enleth: ve7it: machining is probably going to be a no-go, but you should be able to grind through it
08:01 PM enleth: ve7it: use coolant, avoid airborne dust at all cost
08:01 PM enleth: ve7it: the dust is an explosion hazard, *and* toxic
08:02 PM enleth: not hugely so, AFAIK, but enough to take steps to not breathe it even briefly
08:03 PM enleth: ve7it: those things are normally made by pressing in a mold and plating
08:04 PM enleth: (the process is mechanically similiar to the way sintered metal gears are made)
08:06 PM enleth: ve7it: see if you can find a diamond dust-tipped trepanning tool for drilling glass and ceramics
08:08 PM enleth: ve7it: https://www.ebay.com/itm/17mm-Diamond-coated-hole-saw-core-drills-drill-bit-glass-Tile-Marble-Ceramic-/263368704359?_ul=IN
08:09 PM enleth: this, or maybe something slightly more expensive to be sure they used fresh diamond dust and not floor sweepings
08:10 PM CloudEvil: Diamond dust is damn cheap these days
08:10 PM CloudEvil: $100/kg or so
08:10 PM CloudEvil: IIRC
08:12 PM enleth: CloudEvil: it is, but think how much is bound to end up on the floor at the end of the second shift
08:12 PM enleth: the diamond drills that are cheaper even than the really cheap ones have to be made somehow
08:13 PM ve7it: thanks guys.. I am hoping I can find something close... the other option is to build a rotor from scratch (project is converting a car alternator rotor to permanent magnet)
08:13 PM * CloudEvil thinks of the 'glitter on the floor' song.
08:14 PM CloudEvil: ve7it: why. It seems likely that swapping the alternator for something more suited would be a better plan
08:14 PM enleth: yes it does
08:14 PM ve7it: that is an option as well!
08:14 PM CloudEvil: neodynium is murderously shattery from my experience with magnets
08:14 PM enleth: but it doesn't mean you should not try grinding through that magnet, even if it's to tell us how it failed
08:15 PM CloudEvil: The fact all drillbits will contain steel or nickel may make it fun
08:15 PM CloudEvil: i would try using a little dam around the magnet, and a copper pipe and SiC
08:16 PM CloudEvil: And wax the magnet down to a sheet of aluminium or something to stop it shattering on breakout
08:16 PM enleth: right, the back side must be supported
08:16 PM enleth: medium speed, low pressure and lots of coolant or submerged completely might do it
08:17 PM CloudEvil: SiC + water, and change the abrasive after it stops cutting
08:17 PM enleth: a good small drill press might do it if rigged to apply very gentle downwards force on the quill and just left for the 15 minutes it could take
08:18 PM enleth: CloudEvil: you think it'll manage to clog up the cutter?
08:19 PM CloudEvil: enleth: It is a hard brittle substance, it's like pot metal and glass had a baby.
08:19 PM XXCoder: isnt there grinders thats like endmill and such?
08:20 PM XXCoder: might be better
08:20 PM enleth: I'm still betting on a core drill, least amount of material to actually grind up and move
08:21 PM enleth: drilling a small hole tangent to the inside of the large one could help prevent clogging, it works in ceramcs
08:21 PM enleth: and frankly, just about anything else where an abrasive core drill is used
08:21 PM CloudEvil: Probably not.
08:21 PM CloudEvil: it's a neodynium magnet.
08:22 PM CloudEvil: The 'chips' are going to violently stick together like shitty ferrofluid.
08:22 PM XXCoder: https://www.amazon.com/DEWALT-DW5470-5-Piece-Carbide-Hammer/dp/B00004RHCV
08:22 PM XXCoder: i wonder if this would work
08:22 PM CloudEvil: XXCoder: if you want very small bits of magnet, yes.
08:23 PM XXCoder: i cant find that "grinder"
08:23 PM enleth: XXCoder: they don't do shit without hammer action, the edge has a huge positive angle, completely blunt
08:24 PM XXCoder: https://www.youtube.com/watch?v=nFEDIZpG744
08:24 PM XXCoder: guy dont menion what its called
08:24 PM XXCoder: so im not sure what its called yet
08:24 PM XXCoder: though would need more coolant than that due to magnetism
08:25 PM XXCoder: or can heat it beyond curie temperate then re-set it after milling
08:26 PM XXCoder: https://www.youtube.com/watch?v=pxPEWbx-Qs0
08:26 PM XXCoder: "6mm diamant grinder bit (40 grit)"
08:26 PM enleth: CloudEvil: core drill, pecking, really high coolant pressure through a tiny nozzle to forcefully eject the stuff?
08:26 PM enleth: hell of a mess, though
08:26 PM XXCoder: you got coolant spray though spindle?
08:26 PM enleth: wet magnetic crap being shot everywhere
08:26 PM CloudEvil: i think you can probably get away with SiC, and copper pipe and pecking and coolant slowly
08:27 PM XXCoder: bet that'd help
08:27 PM ve7it: one would never get the cuttings off the machine
08:27 PM CloudEvil: All machining done in a little tub
08:27 PM XXCoder: cloud check out video i linked to
08:27 PM XXCoder: rock is in water filled tank
08:27 PM enleth: ve7it: one thing is certain, we're all interested in your results
08:27 PM XXCoder: indeed. upload a video!
08:28 PM CloudEvil: interesting
09:07 PM roycroft: well bummer
09:07 PM roycroft: my dovetail saw just broke
09:07 PM roycroft: i think i can repair it, but it sucks that it broke
09:07 PM roycroft: it's an adria, and one of the first ones made (serial number 60)
09:10 PM CloudEvil: :/
09:24 PM flyback: hey
09:24 PM flyback: can anyone use a via pico itx board here
09:24 PM flyback: 32 bit x86 only
09:31 PM Tom_L: heh
09:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/EPIA-MII-45.jpg
09:39 PM solarwind: flyback Via CPU?
09:40 PM solarwind: flyback I've messed with those back in the day. No reason to use them anymore unless you already have them
09:41 PM flyback: friend is selling a few I guess
09:41 PM flyback: little pico itx one +12 input
09:42 PM solarwind: Speaking of ITX
09:44 PM solarwind: Where is pcw? I wanted to ask him if he was planning on selling PCIe/104 format cards
09:45 PM roycroft: he's probably still in california
09:45 PM roycroft: unless he's on holidays
09:46 PM solarwind: When I checked the site, I only saw PC/104 models and I had to make sure it was 2021 and not 1991
09:47 PM roycroft: connecting with him on irc can be hit or miss
09:47 PM roycroft: more reliably, i think, would be email
09:47 PM solarwind: I know, I mostly just wanted to make that joke
09:50 PM roycroft: btw, are you here to launch a ransomware attack against teh irc?
09:50 PM roycroft: do you intend to hold tom_l's logfiles hostage?
09:51 PM roycroft: i'm not sure he would pay you what you may think they are worth
09:57 PM XXCoder: roycroft: am I missing something?
09:57 PM Tom_L: yes
09:57 PM Tom_L: let it go
10:02 PM roycroft: solarwinds are an internet security company whose code got injected with malware that installed ransomware on hundreds of government and corporate networks a year or so ago
10:03 PM XXCoder: ahh funtimes
10:03 PM perry_j1987: o/ hows everyone doing
10:06 PM Tom_L: hard to say really. we used to talk about linuxcnc here
10:09 PM roycroft: we still do, at about the same rate as we have been for years
10:12 PM roycroft: speaking of which, at least tangentially, is someone willing and able to discuss dc motors drives with me?
10:16 PM perry_j1987: im reading about options to help at my shop with intermintent low voltage
10:43 PM solarwind: No, I took my name from the sci fi artist Peter Jones' collection of paintings from ~1975
10:43 PM roycroft: that's good
10:44 PM roycroft: i wonder if solarwinds.com chose their name for the same reason
10:55 PM _unreal_: You'll never guess where I got mine from
10:56 PM _unreal_: perry_j1987, USA or EU?
10:56 PM _unreal_: perry_j1987, more so wondering what your power is? is it 220 or 120?
11:06 PM _unreal_: what the hell? just got on aliexpress and everything shipping to the USA is dirt cheap?
11:06 PM _unreal_: dirt dirt dirt cheap
11:13 PM roycroft: good dirt is not cheap
