12:21 AM fragalot: hi
12:26 AM IchGucksLive: morning from germany
12:42 AM IchGucksLive: off 2 garden
01:23 AM enleth: hazzy-dev: if you're in the US, tell him to call SSI Shredding Systems and ask for the smallest unit they have
01:26 AM enleth: there is a small problem with shredding aluminum before melting, namely, the surface area gets larger and all the newly exposed surface oxidises immediately, so there's way more aluminum oxide in the melt
01:27 AM enleth: but a large tooth shredder might be a reasonable balance between reducing chunk size and increasing surface area
01:32 AM gloops: yes thats true enleth
01:32 AM gloops: in my dabblings i found it better to get a small volume of molten ally and feed bigger chunks into that
01:34 AM enleth: still, it's better to have more slag to deal with than to have your face melted off by an exploding furnace
01:36 AM gloops: what would make a furnace explode?
01:37 AM enleth: gloops: hazzy-dev described an accident he had a couple hours ago with a scrap melting furnace - they had an oil-filled heatsink sneak through in a pile of regular heatsinks they wanted to melt
01:37 AM enleth: the furnace reacted rather violently
01:37 AM gloops: oh right, yeah adding oil might cause something untoward
01:38 AM enleth: adding oil in a sealed metal container
01:38 AM gloops: i had an explosion but not in the furnace, on pouring, or after pouring
01:38 AM gloops: you dont want any sealed vessels i wouldnt have thought
01:38 AM enleth: sand too wet?
01:39 AM enleth: the heatsink probably had heatpipes in it, but looked like a regular heatsink, they had no way of knowing - thus the idea of shredding the stuff first
01:39 AM gloops: i tried a stone mold, must have been moist inside + the rock was in clean strata - the top layer or 2 errupted
01:41 AM enleth: besides, it might be interesting to see if aluminum oxide slag from a small furnace can be used for anything. that's the same stuff blasting media and sanding/grinding implements are made of, but obviously contaminated and of mixed quality
01:41 AM enleth: still, it might be useful for something
01:42 AM enleth: crush and use for blasting rough, dirty stuff?
01:42 AM enleth: might work
01:42 AM gloops: probably not worth bothering
01:42 AM enleth: probably
01:43 AM enleth: oh, right
01:43 AM enleth: reinforcing resins with it
01:43 AM enleth: much less processing needed
01:43 AM gloops: you can get better seperation with flux
02:08 AM selroc: hi
02:09 AM Deejay: moin
02:24 AM gloops: https://www.ebay.co.uk/itm/Trend-IT-1786520-SPIRAL-CUTTER-CASE-18X45X170X18/362244121932?
02:25 AM gloops: pro spiral cutters run quite expensive
02:36 AM selroc: you would love this https://farm.bot/
04:55 AM jthornton: morngin
04:55 AM jthornton: morning even
05:36 AM * Loetmichel just had to clean up the workbench in the 'shop at work... couldnt see the tabletop any more... a few hours later: on 10 liter bucket full of scrap metal, one 10 liter bucket fuill of plastics and wood scrap, a somewhat clean workbench and the milling cutoffs sorted by material... WHAT a hassle... -> http://www.cyrom.org/palbum/main.php?g2_itemId=11184&g2_imageViewsIndex=1
05:38 AM Loetmichel: uups, wrong link. correct one: http://www.cyrom.org/palbum/main.php?g2_itemId=17095&g2_imageViewsIndex=1
05:49 AM XXCoder: boo

08:01 AM Rab_ is now known as Rab
08:04 AM JT-Shop: morning Pete
08:23 AM Beachbumpete1: howzitgoin JT
08:28 AM JT-Shop: I guess if one HAS to clean a coolant tank out the bandsaw is the least objectionable one to clean
08:28 AM JT-Shop: making a giant spin fixture for a 30" x 48" drum thingy
08:35 AM Beachbumpete1: yeah man those coolant troughs can get kinda nazty
09:08 AM Beachbumpete1: man it feels kinda strange doing all this CAD CAM stuff and not being out in shop like I used to be all the time
09:48 AM JT-Shop: all right the bandsaw is clean and ready for action
09:49 AM roycroft: it's clean, all ready to get dirty?
09:52 AM JT-Shop: and I found a custom fixture screw I lost 6 months ago too
10:12 AM Loetmichel: JT-Shop: in the shopvac?
10:12 AM Loetmichel: thats where i find most of my screws that got dropped in the shop
10:12 AM Loetmichel: *vacuuming all the dirt* *KLONK* "ah, there it was!"
10:19 AM JT-Shop: no in the pan under the bandsaw
10:53 AM JT-Shop: time for lunch
11:18 AM hendrik_cnc: hello, which glade element do i have to use to just add text without overriding it by the hal?

12:03 PM IchGucksLive: hi
12:08 PM fragalot: hey IchGucksLive
12:08 PM IchGucksLive: ;-9
12:24 PM IchGucksLive: im coding on freecad 0.18
12:51 PM hendrik_cnc: hi
12:51 PM phipli: evening
12:52 PM gloops: hello
12:54 PM phipli: my internet seems to be being poor this evening
12:55 PM Beachbumpete1: IchGucksLive NICE MAN I was not aware you were helping with the freecad project. It is looking pretty damn good lately from what I have seen of it.
12:56 PM fragalot: phipli: don't blame me. :3
12:57 PM phipli: my whole connection is playing silly buggers
12:57 PM phipli: so if someone has done something to theCockerel, they've hit it hard
12:57 PM phipli: but I suspect my IP
12:58 PM IchGucksLive: Beachbumpete1, https://www.youtube.com/watch?v=lPrP80Onbog I WILL publish this tonight
01:00 PM Beachbumpete1: so this is for the CAM package then it appears
01:00 PM Beachbumpete1: trochoidal nice
01:00 PM IchGucksLive: no im on PATH
01:00 PM IchGucksLive: ok compile has pased
01:01 PM IchGucksLive: testing
01:01 PM gloops: you know i half suspected thats why archivist went offline phipli, his setup was acting up a few weeks before he went
01:02 PM phipli: hum
01:02 PM JT-Shop: mine is always wonky
01:03 PM phipli: for some reason thecockerel has decided to use its wifi connection despite having a perfectly good ethernet cable plugged in
01:03 PM IchGucksLive: tests are ok i will force a pull request
01:04 PM phipli: bye bye cockerel
01:05 PM phipli: right - its ethernet is working again
01:05 PM phipli: hopefully it will log back in
01:05 PM IchGucksLive: SEE ALL im on 0.18 and PathDressupTroichodal is working SMILE
01:06 PM IchGucksLive: IMAGE http://pasteall.org/pic/fbbb9704ffd79a513749e1f4c608ded8
01:06 PM IchGucksLive: it has been killed by the 0.17 relese
01:11 PM * fragalot pokes theCockerel with a long stick
01:16 PM phipli: <squawk>
01:16 PM fraga1ot is now known as fragalot
01:17 PM * fragalot sniggers at phaxx
01:17 PM fragalot: wait
01:17 PM * fragalot sniggers at phipli
01:17 PM phipli: someone needs help with their tab complete
01:17 PM theCockerel: phipli: 2018-04-26 - 18:15:18 <fraga1ot> tell phipli workaround!
01:17 PM theCockerel: phipli: 2018-04-26 - 18:15:22 <fraga1ot> tell phipli workaround!
01:17 PM phipli: hum
01:17 PM fragalot: on a more important note
01:18 PM fragalot: does anyone know how to shift channels around on irssi
01:18 PM * JT-Shop goes back to work...
01:18 PM phipli: note I can use wildcards and block ips
01:18 PM gloops: why do these dragknives seem to have bearings, when they just sit in the spindle - which has bearings?
01:18 PM gloops: https://i.pinimg.com/236x/65/a1/c0/65a1c002503949753682b204b70e799f.jpg
01:18 PM fragalot: phipli: or you could just ask nicely because there is no real way to stop me on IRC...
01:18 PM fragalot: )
01:18 PM fragalot: :)
01:20 PM phipli: I was going to un-block you yesterday
01:20 PM fragalot: /window move works \o/
01:20 PM phipli: but didn't
01:20 PM fragalot: That's fine, i'm just being an ass.
01:21 PM cradek: gloops: the spindle has too much mass for that tiny knife point to rotate
01:22 PM fragalot: gloops: response time, it reduces inertia
01:22 PM phipli: cutter plotter?
01:22 PM IchGucksLive: and there we go the pullrequest is runing
01:22 PM phipli: (as a tool)
01:23 PM IchGucksLive: i use cutter so offen to cut masks
01:23 PM IchGucksLive: dragnive
01:23 PM IchGucksLive: best G-code is HEEKS on overrun
01:23 PM IchGucksLive: but freecad moves a free inout
01:25 PM IchGucksLive: im off bye as guesdts are already here
01:45 PM gloops: ok thanks re dragknife
01:46 PM fragalot: seems trump has started doing his own damage control, lol
01:47 PM jdh: s/control//
01:47 PM fragalot: jdh: that goes without saying;
01:51 PM gloops: hes coming to the UK in july
01:52 PM fragalot: are they going to ground the beast again on that step at the palace? :P
01:52 PM gloops: not a state visit its on business or something
01:53 PM gloops: he cancelled last state visit, probably because of threats of huge protests
01:53 PM fragalot: is he allowed to do business during his presidency?
01:54 PM gloops: oh yeah, actually i think it might be some political thing, but not an official state visit, no reception from the queen or anything like that
01:55 PM gloops: maybe theyre getting people used to him paying a quick call before they go for the pomp and ceremony
02:07 PM miss0r: As a rule of thumbs; how much can I reduce the axle diameter, when wanting to get a good seal with an axle seal? i.e. I have bought a new axleseal for a 48mm axle, but the axle needs a little touch-up on the surface. How much can I skim off the top, and still be within tolerances?
02:08 PM fragalot: what size is it now, and what size seal?
02:08 PM miss0r: 48, 48
02:08 PM fragalot: what type of seal
02:09 PM miss0r: single lib axle seal, nitrate rubber
02:11 PM fragalot: http://www.skf.com/binary/83-129139/Industrial-shaft-seals---10919_2-EN.pdf
02:11 PM fragalot: page 70
02:12 PM fragalot: well, 71
02:13 PM miss0r: so up to 0.190mm ish
02:13 PM miss0r: undersized... So I should be good removing 0.05mm (I think that will clean it up) Great, thanks ;)
02:15 PM sync: Or you put a repair sleeve on
02:15 PM miss0r: sure
02:15 PM miss0r: but if I can clean it up and stay within tolerances, I will just do that. Otherwise i'll make a sleeve
02:15 PM fragalot: everyone prefers avoiding that though :P
02:16 PM miss0r: Especially because I'm doing this to a bandsaw, i'm planning on selling... So I'm hoping I won't have to spend too much money on repairing. That cuts into my revenues
02:19 PM fragalot: oh in that case slap on thick grease & call it a day xD
02:19 PM JT-Shop: pack it with sawdust and heavy grease :)
02:20 PM miss0r: lol
02:21 PM miss0r: I had to replace two roller bearings, and they were GONE!... so imagine that drive shaft(for the driving bandsaw wheel) flapping in the breeze beating the old oil seal straight to kingdom come. Something had to be done.
02:22 PM miss0r: I bought this fully automatic bandsaw for 250eur and I am planning to sell it for 2000eur
02:22 PM miss0r: It takes stock up to 320mm
02:22 PM fragalot: neat. my bandsaw is 320mm.
02:22 PM miss0r: And all I needed to do was replace 3 bearings, an axle seal & install an inductive switch
02:22 PM fragalot: fully automatic too, as long as you stand there holding the handle & button down.
02:23 PM miss0r: unrelated story: I have a bandsaw for sale, if you are interrested? :D
02:23 PM fragalot: I'll give you 280
02:23 PM fragalot: which is a fair deal, i'd say.. since it's 2nd hand it's worth less than what you got it for.. you probably even wrote it off already,..
02:24 PM miss0r: make it 300(that covers my expenses) & you pay the shipping :D
02:24 PM fragalot: deal.
02:24 PM miss0r: You are aware it weighs around 3500kg? :D
02:24 PM gloops: used bandsaw for sale - ex Titanium Bar Cut to Size Ltd....
02:26 PM fragalot: gloops: I've been tasked by the channel overlords to ask what the hell you're talking about?
02:27 PM gloops: ok ill hold back on the jokes, this is not the quickest group i appreciate that
02:28 PM gloops: https://www.youtube.com/watch?v=eg3yry-B7Ck
02:31 PM gloops: i think that would do quite a bit more than 200mph, still quite responsive when the clock runs out
03:20 PM gloops: Today we’re welcoming @DCMS and @beisgovuk to campus to announce a new £1bn #AISectorDeal to make the UK a global leader in AI. Read more: http://ow.ly/sHO330jGzOI

04:10 PM XXCoder: lol https://www.youtube.com/watch?v=cbbLQcEyz20
04:16 PM hazzy-dev: XXCoder: That is sweet!
04:18 PM gloops: excellent, would love one, but no g code for them
04:39 PM JT-Shop: morning XXCoder
05:31 PM Tom_itx: quiet day
05:32 PM Tom_itx is now known as Tom_L
06:01 PM gloops: https://www.youtube.com/watch?v=i2Eek6B9ApU think i can be a bit more confident with cutter diameter - youd think that would snap
06:07 PM CaptHindsight: https://www.youtube.com/watch?v=de8XlrHRLpY
06:07 PM CaptHindsight: Turning process cooling with cryogenic LN fluid
06:15 PM vuko is now known as patrycja
07:36 PM Tom_L: CaptHindsight, cool... literally
07:58 PM CaptHindsight: is there a way to block the "suggested videos" that pop up over the last minute or two of some youtubes?
07:59 PM CaptHindsight: https://youtu.be/oQwVFauSgvs?t=10m25s for example what if I wanted to see the tools vs the egg video popover?
08:01 PM CaptHindsight: looks like I can delete the area using Inspect Element in the browser tools
08:08 PM MarcelineVQ: you can remove items from the right sidebar by selecting ... and clicking not interested, which used to just be an X that you'd click which was simpler, I'm not aware of a similar feature for the thumbnails after a video
08:09 PM MarcelineVQ: Oh pardon me, that's not even what you were refering to hehe
08:10 PM CaptHindsight: MarcelineVQ: yeah, they cover the videos with popups for other videos before the video is even over
08:10 PM CaptHindsight: at least let it finish first
08:10 PM MarcelineVQ: yeah, youtube sort of banned end-slates so creators have to paste their shit over the actual video now, quite annoying
08:11 PM MarcelineVQ: one more thing you can blame youtube itself for
08:11 PM CaptHindsight: I find myself using Ispect Element more and more often now to view a website they way I want
08:11 PM MarcelineVQ: ditto :(
08:12 PM MarcelineVQ: especially pinterest, holy shit, I don't even want to look at pinterest but the thing I want to look at is on there, and they really don't want you looking at the shit on their site without signing up. I'd probably be signed up if they hadn't annoyed me about having to be signed up too
08:13 PM MarcelineVQ: so it's, select overlay div, delete, view images
08:15 PM MarcelineVQ: I'm too lazy to make a tampermonkey/greasemonkey/whateveritscalled to do these deletions automatically though, if you've an interest that might be a good thing to explore
08:18 PM CaptHindsight: I avoid Pintrest as much as possible for the same reasons
08:19 PM MarcelineVQ: It's just too bad the people posting the things I want to see don't avoid it hehe
09:13 PM CaptHindsight: TU Chemnitz builds electrical motor using copper, ceramics and iron in a single 3D print
09:14 PM CaptHindsight: https://www.youtube.com/watch?v=Ea2wy2NpIdY
09:15 PM hazzy-dev: gloops: That router is hauling!
09:18 PM hazzy-dev: I am always surprised how much it takes to break a .25" bit, I had a .25" carbide bit rapid at 300ipm into a steel strap clamp, it cut about .2" into the side of the .7" thick clamp before breaking
09:19 PM hazzy-dev: I should say while breaking :)
09:24 PM CaptHindsight: how many rpm's?
09:26 PM hazzy-dev: 2000rpm, max my poor gear head mill goes
09:31 PM hazzy-dev: CaptHindsight: I have heard that LN is used for machining certain high explosives, I don't know if it makes it safer, or just makes it easier to hold tolerance
09:32 PM hazzy-dev: I want to make a vortex tube for the mill
09:35 PM hazzy-dev: https://arizonavortex.com/cool-tool/
09:37 PM Roguish: they suck lots of compressed air. hope you have cheap power....
09:45 PM CaptHindsight: hazzy-dev: cooler for many boom-go materials makes them boom-go less
09:50 PM CaptHindsight: https://www.youtube.com/watch?v=i_Vjx6bgF2c evidence to support claim
09:50 PM CaptHindsight: https://mythresults.com/toilet-bomb
10:38 PM hazzy-dev: theCockerel: tell CaptHindsight his research skills are bar none
10:38 PM theCockerel: hazzy-dev: I'll pass that on when CaptHindsight is around.
10:38 PM hazzy-dev: thanks
