01:37 AM IchGucksLive: hi
01:40 AM IchGucksLive: lots of snow in the US east Lake area
01:40 AM MarcelineVQ: it's that time of year hehe
01:40 AM IchGucksLive: looks like spring outside in germany
01:54 AM IchGucksLive: ;-)
02:00 AM gloops: hi Ichs, any new machines on the agenda for next year?
02:06 AM gloops: http://i.ebayimg.com/t/Modern-Abstract-Corporate-Metal-Wall-Art-Sculpture-Silver-Controlled-Chaos-/00/$(KGrHqQOKiQE5E+qdbvEBOTSHWmtl!~~48_45.JPG
02:07 AM gloops: i reckon that is doable on cnc
02:07 AM MarcelineVQ: looks like someone's accidental cnc run already
02:07 AM MarcelineVQ: 'This piece is fucked, give it to the marketing team'
02:08 AM Deejay: moin
02:10 AM gloops: maybe, but people buy it
02:10 AM MarcelineVQ: gloops: therein lies the providence for the little guys :>
02:11 AM gloops: http://www.decosee.com/picture/silver-curved-metal-arts-contemporary-wall-art-inspiration.jpg
02:12 AM gloops: i saw some in a big office building entrance yesterday, this isnt $20 stuff
02:12 AM gloops: well the materials are $20 maybe
02:13 AM MarcelineVQ: the standoffs would be 20$ here hehe
02:14 AM gloops: wonder whats used to mark it
02:14 AM gloops: what cutter or tool
02:14 AM MarcelineVQ: angle grinder and a flapper
02:14 AM gloops: flapper? you mean those sanding things
02:15 AM MarcelineVQ: ye https://www.amazon.com/Angle-Grinder-Flap-Discs-Flat/dp/B0089F2OJI
02:15 AM MarcelineVQ: that piece really is as simple as just some guy swiping an angle grinder in little crescents
02:15 AM MarcelineVQ: well, not so little
02:16 AM gloops: it looks machine guided to me, maybe it is just hand swirling with a grinder but it looks pretty unform, cant see any signs of jerkiness or anything
02:17 AM MarcelineVQ: maybe, looks like a handjob to me but it's not like I've seen a lot of cnc ones to compare
02:17 AM archivist: if done separately then must be cnc
02:18 AM MarcelineVQ: I also don't think it was done seperately, I think two of these pieces (6 panels) were done up at the same time to make the swiping easier then cut apart with a waterjet
02:18 AM gloops: https://www.ebay.com/itm/Modern-Abstract-Silver-Corporate-Metal-Wall-Art-Sculpture-Original-Jon-Allen-/230681675442
02:18 AM MarcelineVQ: *8 panels
02:19 AM gloops: around $200, hes sold 200
02:19 AM gloops: $40 000 one design
02:20 AM MarcelineVQ: what a racket, a grinder and various buffer wheels. good for him :D
02:20 AM gloops: 1mm ally - $20 sheet
02:20 AM MarcelineVQ: is it ally then or laquered steel?
02:20 AM gloops: 4 of those a day would do me
02:20 AM MarcelineVQ: ah yeah it is ally
02:21 AM IchGucksLive: gloops: people like tis
02:21 AM gloops: thats stainless steel maybe, ally is a lot easier to scuff
02:21 AM MarcelineVQ: the listing you posted there says ally, but he probably works in more than one material, can't have everything look the same hoho
02:21 AM IchGucksLive: he made one and then gave it to a iron mill
02:22 AM IchGucksLive: as sculpers do
02:22 AM MarcelineVQ: iron sculptures are quite interesting
02:22 AM IchGucksLive: many make it from clay
02:22 AM IchGucksLive: better to sculp
02:22 AM MarcelineVQ: then cast it?
02:23 AM gloops: youve just got to think up some high brow artsy name
02:23 AM IchGucksLive: its most a 2 way process
02:23 AM gloops: they build a public image
02:24 AM MarcelineVQ: a local here forged that sort of thing, gates made of iron with trees in them with flowers and birds and all sorts of very intricate things, all handmade in steel
02:24 AM gloops: like Rodney Basingstoke
02:24 AM IchGucksLive: most you can buy on homedepo
02:24 AM IchGucksLive: there are catalog of punched and tristed iron bars
02:25 AM IchGucksLive: so just weld it
02:25 AM gloops: Marcel the standard gate is £250 - the art gate is £2500
02:25 AM gloops: same costs
02:25 AM MarcelineVQ: well there is a bit of a time difference in production hehe
02:25 AM enleth: if the 2500 one actually has hand forged ornamentation, it's definitely not same cost
02:26 AM MarcelineVQ: some wire feed to tack on a grate and some pipe slotting for a standard gate isn't in the same cost region
02:26 AM MarcelineVQ: as a forged artsy gate
02:26 AM IchGucksLive: https://www.hornbach.de/shop/suche/sortiment/gel%C3%A4nderst%C3%A4be
02:26 AM MarcelineVQ: mind you the forged stuff I have in mind isn't just 2500 either
02:27 AM enleth: gloops: or do you say that a 6-sided 5 axis setup part is the same cost as the one you'd make on a drill press just because the piece of stock steel you start out with cost the same?
02:27 AM gloops: i noticed my old router made some nice patterns when trying to cut ally, its definately doable on a cnc router
02:28 AM IchGucksLive: https://www.google.de/search?q=schmiedest%C3%A4be&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwiir4C6pKzYAhVBnBQKHdjsDTkQsAQIPw&biw=1181&bih=805
02:28 AM enleth: no, it costs 50 times as much because it needs a skilled machine operator
02:28 AM enleth: and a forged gate needs a blacksmith
02:28 AM gloops: enleth most of this isnt art its some charlatan posing as an artist
02:28 AM MarcelineVQ: gloops: it's surely possible with cnc, this is the more likely route for those pieces you're looking at though https://www.youtube.com/watch?v=gzMBxZ-1ZZY
02:28 AM IchGucksLive: the old iron work is quite a good moneymaker
02:28 AM enleth: gloops: what's art?
02:29 AM gloops: what have the machinists just said - its a bit of scuffed steel!
02:29 AM gloops: not a van gogh
02:29 AM IchGucksLive: im off
02:30 AM gloops: that easy Marcel
02:30 AM enleth: if they spent time at an anvil forging the leaves, swirlies and whatnot, it cost more to make than a welded smooth bar gate, doh
02:30 AM MarcelineVQ: gloops: that easy
02:31 AM MarcelineVQ: take a 7 inch grinder and change your angle slowely as you swipe and you get those crescents
02:31 AM MarcelineVQ: that is to say the angle of the pad to the work surface
02:32 AM gloops: this bloke is taking it to a slightly more controlled method - past halfway in the vid https://www.youtube.com/watch?v=5KmnVLU304w
02:32 AM MarcelineVQ: neto
02:33 AM MarcelineVQ: ah for the treadlike pattern
02:33 AM MarcelineVQ: firetruck steel :D
02:34 AM gloops: enleth the philosophical eventualities of semantics arent important, its joe public whos buying
02:35 AM enleth: gloops: then the 6-sided part "costs the same" as the drill press part, right?
02:36 AM gloops: its not a like comparison really enleth
02:36 AM enleth: why? took more time, required more complex tools that took a more skilled operator to handle
02:36 AM gloops: he cant do six sides on his drill press, not to .005mm
02:38 AM gloops: nor can he ever make 2 identical pieces
02:38 AM enleth: and can't do a forged gate with a bandsaw, a MIG welder, a stock of square tubing and a box of hinges and locks, needs a forge, an anvil, a set of hammers, forging dies and punches and a bunch of other tools
02:41 AM gloops: those are standard blacksmith tools, heh, the problem is todays welder just blobs components together he ordered online, he cant be arsed to make a scroll
02:41 AM gloops: with the scuffing metal, i can do a complicated celtic weave, the angle grinder man is gonna sweat it to do that
02:44 AM archivist: cnc spirograph
02:44 AM gloops: yes, some interesting possibilities
02:55 AM gloops: if you used a flexible 'cutter' like a soft rotary wire brush, tilted at 45 degrees to the surface, the width of the switl can be controlled by the pressure or z height applied
02:56 AM gloops: a bit like spring loaded engraving bits
04:30 AM XXCoder: boomy boom
04:34 AM XXCoder: finished my first and last work day for this week
04:34 AM jthornton: morning
04:34 AM XXCoder: hey jthornton
04:39 AM jthornton: 11F
04:39 AM jthornton: I'll be splitting firewood Saturday for sure
04:41 AM XXCoder: fanastic. 28f lol
04:41 AM XXCoder: its raining just enough to magically avoid ice though there was couple spots
04:42 AM jthornton: I hate cold rain it's the worst frozen bridges black ice etc
04:46 AM XXCoder: yeah
04:46 AM XXCoder: rain definitely is warmer though its melting all remaining snow
05:51 AM jthornton: my morning layer just went into the nest box
06:02 AM Tom_L: 24F
06:05 AM jthornton: dang you are having a heat wave
06:06 AM Tom_L: seems to have flipped around on us
06:10 AM jthornton: skunkworks: was that video just using hal components?
06:35 AM Spida: rene-dev: are you at 34c3?
07:03 AM timm1: .online
07:43 AM gloops: tricky twin screw x axis working by hand, now just the y and the z
07:50 AM skunkworks: jthornton, yes
07:58 AM JT-Shop: skunkworks: can I get a copy of the configuration?
08:01 AM jym: skunkworks: I wouldn't give JT-Shop shit, he's been cruel to the chickens and denying them a UFO hen house ;)
08:08 AM skunkworks: sure - it certainly isn't ready for prime time. It doesn't even shut off if arc is lost.
08:08 AM skunkworks: I will get it when I am back at the shop
08:09 AM skunkworks: (this is what JT-Shop is talking about.)
08:09 AM skunkworks: https://www.youtube.com/watch?v=l5oSA1lPLgA
08:12 AM jym: (This is what I was talking about... https://www.youtube.com/watch?v=5PEEfpc_YKI
08:33 AM DurvalHenke: Good Morning Folks.. Can someone help me ? I Have a job and it was completed, but when i open a new file (gcode) the last job continues there. how to avoid this without closing linuxcnc doing the homing again etc etc..
08:37 AM DurvalHenke: forget it .. it was the FreeCad with some bug . sorry folks to disturbing you ..
08:38 AM jym: DurvalHenke: Not a disturbance in the least
08:39 AM DurvalHenke: I Love FreeCad .. but we must pay attention .. :-)
08:40 AM DurvalHenke: I Use only FreeCad and HeeksCad.. nothing more or else..
08:40 AM * jym waits for ExtremeyOverpricedAndBuggyCAD
08:47 AM gloops: what material you working with Durval?
08:52 AM DurvalHenke: I'm working with wood casted with resin..
08:54 AM DurvalHenke: I'm a ex Smoker .. smoked for 45 years since i was 13 years old.. and now I Do Electronic Cigarettes with Wood, Polyurethane Resin, DNA 250 boards
08:54 AM gloops: very good, thats different
08:55 AM jym: DurvalHenke: Isn't smoking/vaping Polyurethane a lil rough on the lungs??? ;)
08:56 AM DurvalHenke: I have a Homemade CNC Router, with Leadshine Drivers and step motors , a Parallel board madden by a Brazilian Guy.., a Brazilian spindle etc ..
08:57 AM jym: DurvalHenke: You should ask Loetmichel to show you his vape collection sometime
08:57 AM gloops: excellent, turning a profit with that yet? vaping is very popular now
08:57 AM DurvalHenke: and yes i have a question .. How can i clear the old job already done from Linuxcnc..
08:58 AM Loetmichel: isnt that big
08:58 AM cpresser: clear?
08:58 AM jym: Loetmichel: You have a holster, I'd say that is bigger than most
08:59 AM Loetmichel: :-)
08:59 AM Loetmichel: i dont use those small cigs any more though
08:59 AM DurvalHenke: let me put a print screen picture in my dropbox ..
08:59 AM Loetmichel: you mean THAT pic, right? -> http://www.cyrom.org/palbum/main.php?g2_itemId=14757&g2_imageViewsIndex=1
09:00 AM jym: Loetmichel: I have a mech mod with a drip tank and dual coils. Proble is I can't find any juice I like anymore.
09:00 AM jym: Loetmichel: Yeah, that's the pic =)
09:01 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16894&g2_imageViewsIndex=1 <- thats what i use now
09:02 AM DurvalHenke: please help..
09:02 AM DurvalHenke: https://www.dropbox.com/s/fqoni2dibw9hvrw/Screenshot%202017-12-28%2012.58.01.png?dl=0
09:03 AM jym: Loetmichel: What mod is that?
09:03 AM DurvalHenke: see the old job continues there.. how to clear old jobs already done ..
09:04 AM jym: This is excessive long (38m) but there are some really neat things in it too, LOVE the window balcony, that is VERY creative... https://www.youtube.com/watch?v=yRQ3RoDcyjY
09:04 AM Loetmichel: jym: see title Aspire zelos (50W) mod with nautilus2 head
09:04 AM jym: Loetmichel: How do you like it?
09:04 AM Loetmichel: very well
09:05 AM jym: Loetmichel: Can you wind your own coils on that tank?
09:06 AM Loetmichel: i think so, never tried to though
09:06 AM Loetmichel: but IIRC there is a "self.winding" coil holder for it
09:06 AM DurvalHenke: https://www.dropbox.com/s/qan58q2ku5j4858/Foto%2008-10-2017%2018%2024%2029.jpg?dl=0
09:07 AM gloops: i havent got linuxcnc loaded atm, but i wanted to that too Durval, i mainly just restarted linuxcnc
09:08 AM gloops: clever mixing of the resins
09:08 AM archivist: just load a new file, I cannot see why one would want to "clear" unless you have buggy gcode
09:10 AM DurvalHenke: no way.. not buggy gcode.. when the job is done .. if you load a new gcode the old must be closed .. how to do that ?
09:10 AM cradek: do you mean delete the pink path?
09:10 AM DurvalHenke: Yes..
09:10 AM cradek: there is an icon on the toolbar for that
09:10 AM cradek: on the right side
09:10 AM DurvalHenke: if i start again the pink will be milled again
09:11 AM DurvalHenke: F....... unbelievable hahahah .. this thing will bite me .. the snake was there and i did not see..
09:14 AM DurvalHenke: https://www.dropbox.com/s/jf7pbcpezq7eeuv/2017-11-24%2018.01.59.mp4?dl=0
09:14 AM IchGucksLive: hi
09:14 AM DurvalHenke: Hi IchGucksLive
09:15 AM IchGucksLive: :-)
09:15 AM IchGucksLive: cool things you got
09:15 AM IchGucksLive: best is the chip defense
09:16 AM DurvalHenke: Thank You.. if you see the linuxcnc is running through Xming .. the only way i have to lower the base latency test
09:16 AM IchGucksLive: DurvalHenke: i told you to start the job there where you like it
09:18 AM IchGucksLive: dident yopu get thius
09:18 AM IchGucksLive: or dident you still know how to do it
09:18 AM IchGucksLive: i will make a small video to show you
09:18 AM IchGucksLive: if you dont get it
09:19 AM DurvalHenke: ? i did not understand what you say .. my English isn't good enough
09:20 AM IchGucksLive: wait 5min
09:23 AM jym: Loetmichel: Nice, I might look into getting it. https://www.youtube.com/watch?v=Wux7-VzZJKM
09:23 AM archivist: he is not answering the question you asked
09:24 AM Loetmichel: jym: woah, thats a thick accent... where is he from?
09:24 AM jym: Loetmichel: UK I think
09:25 AM Loetmichel: yeah, i figured that... but which corner?
09:25 AM jym: Loetmichel: How long does it take to charge, and can you swap out batteries?
09:25 AM jym: Loetmichel: No clue, just googled
09:25 AM Loetmichel: about 2 hours, and no, not without tools
09:25 AM jym: Loetmichel: Tools, as in soldering iron?
09:26 AM Loetmichel: but there IS a standard 18650 inside, so you CAN change it if you have some small torx and a soldering iron
09:26 AM jym: Loetmichel: Good to know
09:27 AM jym: Loetmichel: How long have you quit analogs now?
09:27 AM Loetmichel: 3 and a bit years
09:27 AM jym: Loetmichel: Nice, good job!
09:28 AM jym: Loetmichel: Are you still gettting the cravings or just enjoying vaping now?
09:28 AM IchGucksLive: DurvalHenke: uploading
09:28 AM Loetmichel: but recently i started scrounging one or two at dinner from a co-worker
09:28 AM DurvalHenke: thank you IchG.
09:28 AM Loetmichel: so i am not totally "smoke free" any longer"
09:29 AM jym: Loetmichel: Ah, ok. Eh, we all have our moments =)
09:29 AM IchGucksLive: hi boddenkreuzer how is it in the north
09:30 AM boddenkreuzer: Hi, its all fine here up north, how is the south of germany?
09:30 AM IchGucksLive: DurvalHenke: only for you https://youtu.be/znvA25QVVmg
09:31 AM IchGucksLive: boddenkreuzer: sunshine outside
09:34 AM DurvalHenke: <IchGucksLive> thank you .. You are amazing..
09:34 AM IchGucksLive: DurvalHenke: only old
09:35 AM IchGucksLive: DurvalHenke: this parts you make what material is it
09:35 AM DurvalHenke: Yes .. me too 60 years Old now.. retired . but in active, if not I will die Young..
09:36 AM IchGucksLive: 70+
09:36 AM IchGucksLive: only rtetirerd here Loetmichel
09:37 AM Loetmichel: IchGucksLive: i still have about 18 years to go ;)
09:37 AM IchGucksLive: you may not make it as you work to hard
09:37 AM DurvalHenke: I do not do Paragliding and Hang-gliding anymore.. after a Crash when I Broke my arms, my wife told me .. Paragliding or ME.. i choose Paragliding if first moment, but thinking better i choose Her..
09:38 AM IchGucksLive: in brasil paragliding do you got montains or from Jesus
09:39 AM IchGucksLive: where in brasil are you
09:39 AM IchGucksLive: its a real big country
09:39 AM DurvalHenke: And now.. after moving to vaping I start a new project .. do my own Milling Router and made some MODS with stab wood..
09:39 AM DurvalHenke: I'm from Sao Paulo ..
09:40 AM IchGucksLive: nice carnalval
09:40 AM IchGucksLive: better then rio
09:40 AM DurvalHenke: but i know all Brazil from North to south .. East to West ..
09:40 AM IchGucksLive: but you need mutch better welders
09:40 AM DurvalHenke: The only place in Brazil that i do not Like is Rio..
09:40 AM IchGucksLive: so many brekdowns last year
09:41 AM IchGucksLive: a Vivo TVGlobo
09:43 AM DurvalHenke: Yes.. and People from Government very very corrupts .. Corruption in everywhere.. and no Safety.. .. two ex governors in Jail .. Deputies in Jail .. Man.. my country is so beautiful but the politicians we have here .. is a 7th plague send by God to destroy humanity
09:43 AM Loetmichel: hihi, i dont need paragliding to get some injuries.
09:44 AM archivist: stabbing is loets choice!
09:44 AM Loetmichel: did about 10 years of stage hand (stage rental)... biggest drop i had back then was 6 meters to concrete ;)
09:44 AM IchGucksLive: im off later ;.)
09:44 AM Loetmichel: archivist: only lately ;)
09:45 AM Loetmichel: ... surporisingly i came off that drop without a single broken bone... but i was black an blue from head to toe ;9
09:46 AM Loetmichel: btw: archivist: you are a brit, arent you?
09:48 AM gloops: Durval brazil needs a donald trump
09:48 AM archivist: Loetmichel, yes
09:49 AM Loetmichel: could you tell me which area of GB that video guy comes from?
09:49 AM DurvalHenke: <gloops> He does not speaks portuguese.. ;-) but yes. we need someone like him.
09:49 AM Loetmichel: [16:22] <jym> Loetmichel: Nice, I might look into getting it. https://www.youtube.com/watch?v=Wux7-VzZJKM
09:49 AM archivist: not at the moment cannot see yt
09:50 AM Loetmichel: ah, thanks for trying thoug ;9
09:50 AM archivist: gloops or phipli too
10:02 AM DurvalHenke: IchGucksLive> DurvalHenke: this parts you make what material is it : They are from Polyurethane Resin, some colors powder, Cactus Chola stabilized with Acrylic resin in a vacuum chamber
10:03 AM gloops: also looks good with metal flakes
10:05 AM DurvalHenke: I have more.. with pine seeds, bamboo, eucalyptus root etc.
10:05 AM enleth: shit, I just checked prices on the Bijur metering units - crazy expensive
10:06 AM enleth: looks like knockoffs are available on Aliexpress, but so far I only see metric versions, no good for an existing imperial system
10:06 AM jym: Loetmichel: I have no clue. I just googled the tank name and that came up as a result.
10:08 AM Loetmichel: he has exactly the same kit that i have here though. just in black while mine is red
10:19 AM gloops: aluminium is terrible for gluing
11:24 AM boddenkreuzer: Hi, I know, raspberry is quite unpopular here, but I want to try to run linuxcnc on it. Has anyone patched the OSADL RT Kernel?
11:32 AM Rab: boddenkreuzer, Machinekit might or might not be what you're looking for: http://www.machinekit.io/docs/getting-started/install-rt-kernel-RPi2/
11:34 AM boddenkreuzer: Thanks, I know machinekit, but I want to use lcnc. I will try to use their images an then install lcnc, hopefully that works
12:07 PM IchGucksLive: hi
12:12 PM boddenkreuzer: Hi, had dinner?
12:16 PM IchGucksLive: :P
12:17 PM IchGucksLive: boddenkreuzer: you still on rasp
12:17 PM IchGucksLive: boddenkreuzer: warumm nimmst du dann nicht eine fertige gbrl
12:18 PM IchGucksLive: kostet kaum 50euro
12:18 PM boddenkreuzer: gbrl doesnt run on RPI
12:19 PM boddenkreuzer: RPI is a great tool and lcnc is great piece of software, I want to have both
12:20 PM boddenkreuzer: I dont want to run a cnc machine, just be able to use lcnc to move something or interact with some sensors or just to can use pid loops
12:22 PM IchGucksLive: ok then go for it
12:42 PM _methods: https://www.youtube.com/watch?v=TteS6q20VUY

01:58 PM Nick-Shop__ is now known as Nick-Shop
02:06 PM DurvalHenke: Hello Folks .. sorry to disturbing you again .. Is about BACKSLASH.. what is machine units .. i have 0.5mm in Z and this is getting me crazy .. because the work accepts very low tolerance
02:07 PM DurvalHenke: machine units = mm or inch ??
02:08 PM gloops: what did you set in stepconfig?
02:09 PM DurvalHenke: [AXIS_2]
02:09 PM DurvalHenke: TYPE = LINEAR
02:09 PM DurvalHenke: HOME = 95.0

02:10 PM DurvalHenke: mm
02:10 PM DurvalHenke: Milimeter..
02:10 PM gloops: so increase the backlash value to 0.5 and test it
02:10 PM DurvalHenke: ok thank you ..
02:10 PM DurvalHenke: :-)
02:11 PM gloops: wheres the backlash from?
02:11 PM gloops: the best way is to deal with the mechanical problem
02:12 PM DurvalHenke: Z axis.. is not ball screw
02:13 PM DurvalHenke: i need to change but only in February
02:13 PM gloops: some people put a counter weight on the z, or use an anti backlash nut for the leadscrew
02:15 PM DurvalHenke: yes i know.. but is hard do find here.. thats why I'm changing to ball screw
02:17 PM gloops: translucent concrete https://i.pinimg.com/564x/63/c7/c8/63c7c8a702cc2591cbc404a1dfaf81ab.jpg
02:17 PM Loetmichel: gloops: enough air in it. easy
02:19 PM gloops: air is not good in concrete lol
02:20 PM DurvalHenke: Perfect.. working like a charm .. Just Perfect. now i have 0.0000 error thank you all
02:20 PM DurvalHenke: thank u gloops
02:21 PM gloops: i think you would have worked it out Durval heh
02:26 PM gloops: just a tip DurvalHenke, when you start editing the INI and HAL files, make a copy of the original file before you make changes, then if you get in a mess you can just use the old file again and go back to what you had before
02:28 PM Loetmichel: gloops: air no good in concrete? tell that these guys: https://www.ytong-silka.de/ytong-porenbeton-wandbaustoffe.php
02:30 PM DurvalHenke: yes i've learned in a hard way.. :-(
02:31 PM gloops: thats screed i think Loetmichel
02:31 PM gloops: anyway this stuff is made with optical fibres
02:32 PM Loetmichel: thats cheating
02:33 PM Loetmichel: gloops: the americans call that stuff "AAC" autoclaved aerated concrete.
02:33 PM Loetmichel: and it IS made of sand, chalk and cement.
02:34 PM gloops: we call them breeze blocks
02:36 PM gloops: generally if you want strong concrete you keep air out
02:36 PM Loetmichel: yeah, they are about 30% weaker than poured concrete
02:36 PM gloops: either vibrate it or press it, like paving blocks - theyre pressed to squeeze all the air out
02:37 PM Loetmichel: but at the same time you need big walls anyway for it to be thermal insulation.
02:37 PM Loetmichel: wen you build stuff with ytong i mean
02:37 PM MarcelineVQ: somebody help that lady she's being eaten by a wall
02:38 PM Loetmichel: its funny though
02:38 PM Loetmichel: i once helped a friend make an addition to a 3 story house.
02:39 PM Loetmichel: we made the walls of the addition with said ytong blocks
02:39 PM * jym once helped make a subtraction to a 3 story house =)
02:39 PM Loetmichel: so i was standing there, throwing the BIG blocks (62.5cm by 25cm by 30cm) to the third floor where the friend was catching them
02:40 PM Loetmichel: an old lady came by. lokked. stood still like she was struck by lightning... she must have thought i was superman ;)
02:41 PM gloops: lol
02:41 PM gloops: like when the incredible hulk lifts a boulder made from polystyrene
02:41 PM Loetmichel: yes
03:03 PM gloops: You only need 39 digits of pi to calculate the circumference of the visible universe to an accuracy of less than the width of a proton
04:13 PM JT-Shop: till we make a bigger telescope...
04:15 PM MarcelineVQ: 39 digits is 37 more digits than you need to have a floating point rounding error anyway
04:17 PM SpeedEvil: https://imgur.com/gallery/D5f5i9W What not to do when casting metal.
04:18 PM MarcelineVQ: good thing humans are so full of water
04:18 PM CaptHindsight: vodka makes you strong
04:18 PM CaptHindsight: fake news
04:18 PM CaptHindsight: it must be ok since he's fine , see
04:19 PM MarcelineVQ: soon as your skin dries out the metal's gonna stick since there won't be a steam barrier pushing it off
04:20 PM SpeedEvil: I think he's dipped his hands in water
04:20 PM MarcelineVQ: you can see examples of this effect in vids where people dip their hands in lead, it's pretty cool stuff tbh
04:20 PM MarcelineVQ: yeah you can fee it drip as he leans down
04:20 PM MarcelineVQ: *see
04:20 PM SpeedEvil: yeah - taking it to red heat is another level
04:21 PM SpeedEvil: Aluminium I guess
04:21 PM CaptHindsight: https://imgur.com/gallery/837NK1o Thermochromic hair dye, a few images down from ^^
04:22 PM SpeedEvil: That's neat too
04:22 PM SpeedEvil: I can't wait till we get addressible hair dye
04:22 PM MarcelineVQ: I'm reminded of the poison dart frog when I see the rainbow hairs
04:22 PM SpeedEvil: Internet of hair
05:19 PM gloops: thats like those old fakirs who walk on hot coals
05:19 PM gloops: theres a scientific explanation for how they do it
05:21 PM gloops: its also like fung fu, when you hit something you never hit it with a rigid hand, you roll the hand WITH the thing as you hit it
06:11 PM MrHindsight: https://imagebin.ca/v/3mIbotxtK0D7 what I hate about restoring old cars
06:12 PM MrHindsight: fabricating things like this gives me no joy
06:16 PM SpeedEvil: 3d print it!
06:17 PM cradek: um what are they?
06:17 PM MrHindsight: rectangular tubing and two plates
06:18 PM MrHindsight: cradek: the brackets that hold on the rear bumper
06:18 PM MrHindsight: $75ea from the dealer, $50/pair used + shipping
06:19 PM cradek: huh from the strength of those, looks like the bumper is purely cosmetic
06:19 PM Wolf__: probably meant to crush on impact
06:19 PM MrHindsight: yeah, styrofoam is actually part of the structure
06:20 PM MrHindsight: urethane skin, Styrofoam, aluminum tube, then these to the body
06:21 PM MrHindsight: stamped from ~20ga cold roll
06:22 PM MrHindsight: https://parts.nissanusa.com/nissanImages/A35/031_A35_0000000207.jpg typical
06:23 PM Wolf__: bumper imo https://i.imgur.com/gzw7p90.jpg
06:26 PM MrHindsight: unfortunately too wide for the car
06:27 PM Wolf__: custom built lol
06:27 PM MrHindsight: not a single steel tube in the entire body
06:28 PM MrHindsight: all frame-ish parts are stamped from thin sheet
06:28 PM MrHindsight: the rockers are made from 3-4 layers of ~18ga
06:30 PM Wolf__: rolling recycled soup cans
06:30 PM sync: not at all, luckily
06:30 PM roycroft: well that was nice timing
06:30 PM roycroft: i needed a countersink with a 7/16" pilot for this router table project
06:30 PM roycroft: it was supposed to arrive last week, but it was delayed
06:31 PM roycroft: i forged ahead with the project
06:31 PM roycroft: and today got to a stopping point, waiting for the countersink
06:31 PM roycroft: i started closing up the shop when the ups truck rolled up with the very item
06:31 PM roycroft: that really puts the "just" in "just in time"
06:33 PM MrHindsight: roycroft: and now every other UPS delivery will be late for the next several weeks :)
06:34 PM MrHindsight: seems whenever we get a courteous, conscientious regular on time driver they trade them for someone new
