12:34 AM IchGucksLive: hi
02:02 AM Deejay: moin
03:40 AM gloops: few hours spare today, see if i can make the breakthrough
03:40 AM gloops: adjustability is necessary with welded machines, but it is a pain to set up
03:40 AM * Wolf is making chips
03:41 AM archivist: I saw a machine build in progress last night
03:42 AM Wolf: right now Iâ€™m debaiting if I should pull the crossslide off the lathe and drill and tap it on the mill vs doing it all with a hand drill
03:43 AM gloops: what kind of machine archivist?
03:43 AM gloops: better drilling in a fixed spindle than hand for tapping
03:44 AM archivist: he is making a router
03:44 AM Wolf: pain in the ass, but Iâ€™m thinking outcome would be better drilling on the mill, all the tapped holes might actually line up with the bracket then
03:46 AM archivist: having large enough travels to drill in line :)
03:46 AM gloops: big/small iron/alu etc archivist?
03:47 AM archivist: his gantry is about 3 ft,
03:47 AM archivist: al
03:47 AM archivist: with steel runners/V wheels
03:47 AM Wolf: yeah, I have 513mm travel on the X on this mill
03:48 AM archivist: one thing that bugs me all the time is short travels
03:48 AM Wolf: y axis is another storyâ€¦
03:49 AM Wolf: new vise gets here friday, then Iâ€™ll pull this other vise apart and see if I can get some of the lift out of it
03:50 AM Wolf: and start planning out a mounting plate for it to get it the same height off the bed as the new one =)
03:53 AM gloops: http://www.ebay.co.uk/itm/EU-Stock-New-36V-350W-9-7A-DC-Switching-Power-Supply-For-CNC-Milling-3D-Printer/273014612322?
03:53 AM gloops: on that psu, the output is marked 12v on the terminals, does that mean each terminal gives 12v - for a total of 36v?
03:54 AM SpeedEvil: No
03:54 AM SpeedEvil: Two sets of three terminals
03:54 AM Wolf: generic photo
03:54 AM SpeedEvil: The three terminals are in parallel
03:54 AM Wolf: pic is a 12v psu
03:55 AM SpeedEvil: Ah
03:55 AM SpeedEvil: yes, that too
03:56 AM archivist: datasheet image does does not have that voltage!, stock images
03:56 AM Wolf: love how the spec sheet in the ad doesnâ€™t even have a 36V on it lol
03:56 AM SpeedEvil: Though ...^
04:01 AM gloops: its advertised as a 36v
04:02 AM gloops: Speedevil by each terminal i meant each set
04:03 AM SpeedEvil: 0V and 36V each have three terminals connected to them in parallel likely.
04:03 AM SpeedEvil: You cannot use it as a 12V supply, they are completely electrically in parallel and no seperate 3*12V PSU exists in there
04:04 AM archivist: at those prices you only get one supply
04:04 AM gloops: that is the wrong photo anyway its an s-350-12 should be s-350-36
04:04 AM gloops: thats ok, i want a 36v supply, just caught my eye the pic showed 12v
04:06 AM SpeedEvil: Consider if you trust someone that can't put the right picture on, and fails to document the supply in the data they do post is very competent to sell power supplies.
04:06 AM SpeedEvil: ^that someone
04:06 AM gloops: all the german stock ones are the same photo
04:07 AM gloops: http://www.ebay.co.uk/itm/EU-Stock-350W-24V-AC-to-DC-Switching-Power-Supply-14-5A-CNC-Router-3D-Printer/302435781399?
04:07 AM gloops: 24v
04:08 AM Wolf: go as high as the steppers/drivers will take IMO
04:09 AM gloops: have tried a 48v - it gives out 54v
04:09 AM Wolf: you might need a 2nd psu for control stuff tho, I used a 12v/5v dual PSU on my cnc build to run everything else except the steppers
04:09 AM gloops: drivers max 50v
04:09 AM Wolf: should be a adjustment pot on the psu
04:10 AM Wolf: if you are using one like linked
04:13 AM gloops: yes it was 48-60, both the ones ive got the actual volts are higher than the specs
04:15 AM gloops: thats ordered anyway, it is in the hands of god
04:33 AM Wolf: I donâ€™t think he has much to do with electronics
04:46 AM jthornton: morning
04:47 AM XXCoder: yo
04:48 AM jthornton: 11Â°F
04:49 AM Loetmichel: gloops: those adjustment pots usually go a lot further than the range printed on them.
04:50 AM XXCoder: 45f and started having rain that wont stop for 5 days
04:50 AM Loetmichel: so if you have an "48 to 60V" meanwell-like open fram PSU it should be adjustable from about 42V to 65V or something in that ballpark.
04:50 AM Loetmichel: if its not then there is something fishy.
04:50 AM XXCoder: in least its not 40 days and nights lol
04:56 AM jthornton: I wonder how long it takes an egg to freeze at 11Â°F?
05:01 AM XXCoder: good question lol
05:01 AM XXCoder: science time!
05:02 AM * XXCoder grabs lab suit, then realizes he don't live at cold enough area
05:03 AM XXCoder: jthornton: check this out https://static.interestingengineering.com/images/JANUARY/sizes/mercedes_resin_resize_md.jpg
05:04 AM Loetmichel: freezing point for the average chicken egg is about -2.8Â°C
05:04 AM Loetmichel: so yes.
05:04 AM XXCoder: that vehicle may well last thousand years
05:04 AM XXCoder: there is likely to be some internal rotting but otherwise...
05:06 AM Loetmichel: XXCoder: careful: resin like that is prone to decomposition by UF light.
05:06 AM Loetmichel: U
05:06 AM jthornton: it's not the freezing point I'm worried about but what is the rate of cooling for a 45g egg from 107Â°F to say 40Â°F
05:06 AM Loetmichel: UV
05:07 AM XXCoder: loet yeah guessed that. really all we need to do is bury it away from light
05:07 AM enleth: wonder if they put moisture absorbents inside and coated the whole thing in mold release
05:07 AM Loetmichel: jthornton: one night at -11Â°c should be more than sufficient.
05:07 AM XXCoder: enleth: or completely filled inside also]
05:07 AM jthornton: they don't lay at night
05:08 AM enleth: well, with mold release you actually could get it out
05:08 AM Loetmichel: enleth: unless the resin seeped into all those crevices and inside the engine/passenger compartement
05:09 AM Loetmichel: jthornton: ah, you mean over day between them laying them and you picking them up in the evening?
05:09 AM Loetmichel: arent they putting them into nests and sit on them?
05:09 AM Loetmichel: the hens i mean
05:09 AM jthornton: yea, I pick them up all day just wondering should I check each hour or more often
05:10 AM jthornton: no, they lay in a roll out nest box
05:10 AM Loetmichel: i see
05:10 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-20.jpg
05:11 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-21.jpg
05:11 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-22.jpg
05:12 AM jthornton: they have been up for 1/2 hour now
05:14 AM enleth: good thing the hens probably aren't smart enough to constantly wonder "where the heck did the egg I just laid go?"
05:15 AM Loetmichel: you know what they say in germany? "you have to have one neuron more than a hen so you know not to shit on the backyard pavement"
05:15 AM Loetmichel: :-)
05:15 AM Loetmichel: + at least
05:16 AM jthornton: enleth: sometimes they look for them behind the dividing wall
05:19 AM jthornton: looks like it takes about 3 hours to freeze or so
05:19 AM jthornton: now to figure out how to execute a command at boot up on the rpi
05:22 AM enleth: /etc/init.d/rc.local probably
05:22 AM jthornton: systemd is the new way
05:24 AM enleth: ah, right
05:25 AM enleth: no idea then, avoiding this thing like the plague it is
05:32 AM nallar is now known as Ross
05:33 AM gloops: all the brooding instincts have been selected out with top laying breeds, you might get the odd one revert
05:33 AM gloops: silkies are often used to sit eggs, theyre still broody, quite a few old breeds are
05:34 AM jthornton: mine are heritage breed Rhode Island Reds
05:34 AM Tom_L: 5°F
05:35 AM gloops: it was the likes of rhode island reds that knocked ducks off the top spot for laying
05:36 AM gloops: everybody used to eat duck eggs, ducks arent suited to cage life though, and top ducks lay slightly less than top chicken breeds
05:38 AM jthornton: this looks promising https://elinux.org/RPi-Cam-Web-Interface
05:41 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Wiring/X_Limits_wiring.jpg
05:41 AM gloops: oh to be wiring
05:41 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Wiring/X_Axis_Dragchain.jpg
05:42 AM XXCoder: getting there!
05:42 AM XXCoder: also, rails on moving part?
05:42 AM gloops: youll be firing up before me Tom
05:42 AM XXCoder: curious if you did that way becvause its stronger or something
05:42 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Wiring/Y_Dragchain_Bottom.jpg
05:43 AM Tom_L: Y dragchain
05:43 AM jthornton: Tom_L: nice
05:43 AM Tom_L: slow but sure
05:45 AM gloops: ive got some tiny alignment issues, i made it adjustable so no major problem, but getting every set bang on is proving tedious
05:46 AM gloops: move one thing - something else is out
05:48 AM jthornton: that sucks
05:48 AM jthornton: finally a camera software that just works
05:48 AM jthornton: I'll start with a fresh install of rpi tomorrow
05:49 AM gloops: just got to be patient and get it right, its not bad as it is but im not doing anything else till im happy, then should be very quick
05:49 AM jthornton: yea if one of mine get broody she can sit on ceramic eggs lol
05:55 AM XXCoder: how long does it brood on fake egg?
05:55 AM jthornton: dunno, never tried it
05:56 AM jthornton: fertilized chicken eggs usually take exactly 21 days to hatch
05:59 AM XXCoder: I guess chicken would give up after 21 days
06:00 AM SpeedEvil: They're not that smart
06:10 AM jthornton: what's the website with 3d printed models?
06:10 AM jthornton: thingiberse
06:12 AM XXCoder: yeah thingverse
06:12 AM XXCoder: there is others but that one is common
06:12 AM XXCoder: thingiverse
06:16 AM jthornton: hmm I think I'll use a bell box if the rpi fits inside it
06:22 AM enleth: there seems to be a lot of info on machining cast parts and weldments as it's done a lot nowadays - but what about machining forged parts? any interesting problems there, like hard spots when machining welds?
06:44 AM jthornton: hmm I wonder if I have some 2mm screws laying around from model helis
06:53 AM SpeedEvil: enleth: forged what?
06:54 AM XXCoder: forged blocks for example
06:54 AM XXCoder: enleth: ran forged blocks before its no fun lol its not consient as usual blocks
06:56 AM enleth: SpeedEvil: forged steel, like small machine/tool parts that need flats and pockets milled to fit something else properly
06:57 AM SpeedEvil: ah
06:58 AM enleth: so the milling ops are likely to be right where the material was stretched/compacted while forging, like turning a forged hole (no idea what's the proper name for hammering a wedge through a red hot part to make a hole) into a precisely sized milled pocket
06:58 AM enleth: exactly like you'd do with a casting that has a hole that needs to be milled to size
06:58 AM XXCoder: yeah it sometimes changes as you mill it also
06:58 AM XXCoder: releasing stresses and such
06:58 AM XXCoder: even if making part from entire block
06:59 AM enleth: so I'd expect it to be like working a casting, but worse
07:00 AM enleth: but I've never done it and quick googling suggests there isn't much in the way of modern publicly available information on that
07:00 AM archivist: might find some old books on the subject
07:01 AM enleth: some people publish videos of castings being machined on YT, but so far I've never seen a contemporary video of a modern machine tool cutting into a forged part
07:01 AM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=forging
07:02 AM SpeedEvil: enleth: As a general point, the stresses are very, very anisotropic
07:02 AM SpeedEvil: enleth: and the surfaces might be quite hard, depending on stuff.
07:02 AM SpeedEvil: Meaning, cut something and it may curl badly.
07:02 AM archivist: may need a rouging stage
07:03 AM SpeedEvil: cold rolling is basically forging.
07:03 AM XXCoder: that just makes it extra fun
07:03 AM XXCoder: holes could be oval or egg shaped
07:03 AM SpeedEvil: and all the issues of that arise - springing when cutting, ...
07:03 AM SpeedEvil: Perhaps not as bad as machining prince rupert drops.
07:03 AM enleth: but it surely is being done, some things must be forged for the extra strength and modern precision designs call for milled mating surfaces
07:03 AM XXCoder: I had to check all features each part because it varies so much
07:03 AM SpeedEvil: enleth: sure.
07:04 AM SpeedEvil: enleth: it can be done, you may need to work out a precise cutting plan that works for your particular forging
07:04 AM SpeedEvil: you probably can't treat it like a homogenous block of metal.
07:05 AM XXCoder: thats very much a big noper
07:05 AM enleth: I imagine that even the exact sequence of forging ops is important, as it's not abut the final shape of the part, but also about what material was moved where and how
07:05 AM SpeedEvil: yes
07:05 AM SpeedEvil: There are 'proper' murderously expensive tools to calculate this.
07:05 AM SpeedEvil: that is - residual stress and properties after forging
07:07 AM archivist: with proper forging you get much better grain direction for strength
07:07 AM XXCoder: almost all of parts in shop is from extruded block or cast parts
07:07 AM SpeedEvil: In some cases, molding can approach forging with modern alloys and more complex molds, if you can trade off size for stiffness
07:08 AM XXCoder: and money saving if its expensive metal
07:08 AM SpeedEvil: Forging is ridiculously expensive as a way to machine a part in general.
07:08 AM SpeedEvil: Until you get up to very large parts, when it may be lots cheaper.
07:09 AM archivist: for low volume, very cheap for high volume like bolts
07:09 AM SpeedEvil: Forming a crankshaft by milling six foot diameter bar, for example may be problematic.
07:10 AM XXCoder: speed saw video of big machine doing exactly that.
07:10 AM XXCoder: amazing
07:10 AM XXCoder: among many tools it used 2 meter drills
07:10 AM XXCoder: angled in
07:10 AM SpeedEvil: Rather than bending/forging a one foot diameter bar, I mean.
07:11 AM XXCoder: what ya think of additive=-subtractive machine
07:11 AM XXCoder: it welds up and mills em
07:11 AM SpeedEvil: neat.
07:12 AM SpeedEvil: Imagine if it could include bar and ... stock
07:12 AM SpeedEvil: for reducing time.
07:12 AM XXCoder: yeah
07:13 AM XXCoder: its still very early stage
07:13 AM XXCoder: probably wont be common for another 10 to 30 years
07:14 AM XXCoder: well night
07:28 AM SpeedEvil: night
07:29 AM archivist: gloops, print and frame http://www.collection.archivist.info/archive/catalogues/CT169_Guest_and_Chrimes/page_0003.jpg
07:49 AM JT-Shop: hmm McMaster Carr started giving me 2%10 terms :)
08:03 AM gloops: interesting to see some of the stuff that went on in that building archivist
08:03 AM gloops: you see old photos of soot and grime and blokes with flat caps and get the impression it must have been like big hammer stuff, they did some marvellous things
08:07 AM archivist: I thought the title amusing and suitable for a framed image
08:07 AM archivist: and make a few wince
08:07 AM gloops: yeah could be taken the wrong way heh
08:11 AM gloops: but wothout stuff like that, no sanitation, no plumbing, no real civilisation
08:12 AM archivist: romans had sanitation, of a sorts
08:14 AM SpeedEvil: you don't need plumbing for sanitation.
08:14 AM SpeedEvil: But your labour costs skyrocket
08:14 AM gloops: they did, so did the elizabethans, but not really adequate for a city like london, if you want to eliminate typhus and the like
08:15 AM MarcelineVQ: pshh, when you build on a river if you jump dump it on the road the rain'll take it away ;>
08:15 AM MarcelineVQ: *just dump
08:15 AM gloops: and when the sun comes out the puddles become factories for deadly bacteria
08:17 AM archivist: parked my arse here https://www.dreamstime.com/royalty-free-stock-photo-roman-latrine-leptis-magna-white-marble-seating-communal-ancient-north-african-site-image36612195
08:17 AM archivist: its the polishing stick they used to spread it about that amuses me
08:19 AM gloops: the victorians excelled at bog making
08:24 AM gloops: doesnt just happen, for a modern sewage system, you need the vision, the political will, the money, the civil servants, the civil engineers, the mechanical engineers etc, a whole list of other things all have to be in place, the ability to design and record and rationalise
08:24 AM archivist: or a large enough stink to make things happen
08:25 AM gloops: yes, a stink in the houses of parliament from the thames helped bring things to a head
08:27 AM MarcelineVQ: that tends to be the way to get things done in this world, park the annoyance next to the powerful
08:28 AM MarcelineVQ: we should apply this method in a useful way, any ideas?
08:28 AM gloops: the debate had been ongoing but during a certain period the stink choked them out in parliament, i think it got moving pretty soon after that
08:29 AM gloops: https://en.wikipedia.org/wiki/Great_Stink
08:32 AM SpeedEvil: gloops: you don't need a modern sewerage system to collect faesces and urine.
08:32 AM SpeedEvil: You can do it with pots and laws and carts.
08:33 AM SpeedEvil: Doing that alone would provide nearly all of the health benefits.
08:34 AM gloops: they used to save urine for tanning
08:34 AM SpeedEvil: yeah - but not all of it.
08:34 AM gloops: the poor used to sell it - for very little, thats where a lot of sayings come from - piss poor
08:35 AM gloops: taking the piss - stealing someones urine
08:36 AM gloops: you can do it that way SpeedEvil, i suppose the main point is understanding that not removing it causes health problems
08:36 AM SpeedEvil: indeed
08:36 AM gloops: a rational efficient sewage system is a great benefit to civilisation though
08:37 AM SpeedEvil: that doesn't mean a 'western' water based one though.
08:37 AM gloops: Mao banned the practice of using human manure - which was universal in china, typhus down about 80% i think
08:37 AM SpeedEvil: composting toilets - for example - work fine
08:37 AM SpeedEvil: Human manure - properly treated - is fine
08:37 AM gloops: yes a deep enough hole is sustainable for sewage
08:37 AM gloops: but the hole is also a problem
08:38 AM gloops: SpeedEvil but storing it in buckets and throwing it about on the land isnt fine
08:38 AM SpeedEvil: heat to 60C for 15 min, or compost
08:38 AM Loetmichel: gloops: would be fine if heated beforehand
08:39 AM archivist: NK has a human worms problem due to use as a fertilizer
08:39 AM Loetmichel: so the virii are dead
08:39 AM Loetmichel: NK?
08:39 AM gloops: intestinal parasites all kinds of stuff
08:39 AM MarcelineVQ: that's a good point, parasites are a lot more resistant than bacteria, especially in egg form
08:39 AM archivist: North Korea
08:40 AM Rab: We make this, on the outskirts of town near the airport: https://en.wikipedia.org/wiki/Dillo_Dirt
08:40 AM gloops: in vietnam they used to smear booby traps with faeces, lethal if it gets into an open wound
08:40 AM Loetmichel: nothing which wouldnt die in enoughh heat
08:40 AM Loetmichel: archivist: ah!
08:40 AM Rab: Bad area to be working, if the wind is blowing the wrong way.
08:41 AM MarcelineVQ: I'd be more concerned about heavy metal concentration in human waste used as fertiziler, we are at the top of the foodchain after all, that's just going to concentrate it more
08:41 AM Rab: Several times the "dirt" hill has caught fire (possible self-ignition, I guess) and smoldered for days or weeks. The smell is unforgettable.
08:41 AM gloops: theyve built an anaerobic compost station not far from here, very bad smell until they got it right
08:41 AM MarcelineVQ: Rab: omy
08:41 AM Loetmichel: Rab: i can imagine
08:42 AM gloops: the council spent millions, said it would make big savings on landfill and collection and so on, they were even going to sell the compost - its been a costly failure
08:43 AM Loetmichel: MarcelineVQ: i think countrys that have problems getting any other fertlizer than human manure would have other problems as heavy metal concentration
08:43 AM gloops: we're now paying more and get fewer bin collections while they pay for it
08:43 AM MarcelineVQ: Loetmichel: as you can see from Rab's comment, it's not just those countries showing interest in it
08:44 AM Loetmichel: MarcelineVQ: in Rabs case it is monitored though, so no problem there either
08:44 AM MarcelineVQ: famous last words :X
08:45 AM Loetmichel: if there were a heavy metal concentration in it the city would have to dispose it as toxic waste.
08:45 AM Loetmichel: would have... if noone looks the other way of course
08:48 AM Loetmichel: on the other hand: i am not called "loetmichel" for nothing... i am soldering since i was 6... now that i am close to 49 i dont really want to know my lead in blodd count ;)
08:49 AM archivist: soldering wont give you a lead problem, fumes from driving and lead in pipes were worse
08:53 AM Loetmichel: chewing on the solder wire does... a bit ;)
08:54 AM Loetmichel: (3rd hand problem)
08:55 AM Loetmichel: but granted, metallic lead isnt that easy to get into the the body as fumes are (inhaling)
08:57 AM Rab: Lead vaporizes at far higher than typical soldering temps. Flux is a greater hazard, by far.
08:59 AM Loetmichel: Rab: i use only rosin core wire
08:59 AM Loetmichel: and rosin flux
08:59 AM Loetmichel: not that hazardous at all
08:59 AM Loetmichel: (if you dont count losing nose hairs when trying to get that stuff out of the nose after a day of soldering)
09:00 AM Rab: Loetmichel, rosin is supposed to be less toxic than no-clean fluxes, but I doubt it's good to breathe on a long-term basis.
09:00 AM Rab: I use no-clean flux exclusively, with fume extraction.
09:00 AM Loetmichel: ask catholic preist if they have problems
09:00 AM Loetmichel: thats the same stuff in that smoke pendulum
09:00 AM Loetmichel: (pretty much)
09:01 AM Loetmichel: rosin is just pine resin cooked a while to contain no water solube parts any more
09:44 AM * Loetmichel just made another bit of "Alu-origami"... pretty good for freehand bending without a brake if i may say so myself: http://www.cyrom.org/palbum/main.php?g2_itemId=16940&g2_imageViewsIndex=1
09:45 AM skunkworks: Loetmichel, very nice!
09:46 AM skunkworks: lots of hunks of metal for bending?
09:46 AM skunkworks: or oak ;)
09:46 AM Loetmichel: nope, just hands
09:46 AM archivist: vice and angle iron
09:46 AM Loetmichel: but i milled 0.8 by 2mm channels on the inside to have only 0,7mm left to bend
09:47 AM Loetmichel: and to define WHERE the bend will sit
09:47 AM archivist: he might be cheating and grooving the bend
09:47 AM Loetmichel: i did
09:47 AM skunkworks: ah - cool - still very nice looking
09:47 AM Loetmichel: i dont have THAT much force in my fingers ;)
09:48 AM skunkworks: heh - I was going to say - hands of steel!
09:48 AM Loetmichel: hard enough to do the 0,7mm left on the small strips without any vice ;)
09:49 AM MarcelineVQ: is this rolled alu?
09:49 AM skunkworks: You need to requisition a vice and finger brake..
09:49 AM Wolf: no bending here.. https://i.imgur.com/NHOpv7X.jpg https://i.imgur.com/RuNzRrr.jpg =)
09:50 AM Wolf: more brackets to build still....
09:50 AM FinboySlick: Loetmichel: You're like a Trumph TruBend... But more german ;)
09:50 AM skunkworks: Wolf, awesome
09:50 AM skunkworks: Why not just cnc it :)
09:51 AM Loetmichel: MarcelineVQ: its 1,5mm thick AlMg3 sheet metal
09:51 AM Loetmichel: no idea what "rolled alu" is, sorry
09:51 AM MarcelineVQ: as in not-cast, just wondering if there's a fatigue concern cutting into the metal before bending on pieces with a rolling grain
09:51 AM Wolf: probably take longer to cad/cam the parts then just making it up as I go lol
09:52 AM Wolf: this thing was bad enough https://i.imgur.com/RQJrIWW.jpg
09:53 AM FinboySlick: https://www.youtube.com/watch?v=4FkzLs7cLes <-- I assume you guys have seen this. It's hacky but i think it's a pretty cool idea regardless.
09:54 AM MarcelineVQ: sintered steel? most metal gears in consumer products are made that way, it's neat stuff
09:55 AM archivist: sintered is not quite solid though
09:55 AM MarcelineVQ: hmm, the comments are suggesting it's not sintering
09:56 AM Wolf: diy sintered isnâ€™t solid, commercial units are pretty good
09:56 AM MarcelineVQ: still seems like sintering, it's just using sand to keep the voids filled
09:57 AM Wolf: sand cast sintered in a kiln I dunno aboutâ€¦
09:58 AM MarcelineVQ: I hope it's special sand, there's a looot of inclusion in these example shots
09:59 AM MarcelineVQ: a step in the right direction though, gotta start somewhere
09:59 AM Wolf: spaceX uses metal 3d printed parts in their rockets
09:59 AM Loetmichel: MarcelineVQ: of course it is rolled alu then
09:59 AM Loetmichel: not cast
10:00 AM Loetmichel: i dont know if there IS any 1,5mm sheets in cast alu
10:01 AM MarcelineVQ: Loetmichel: it could be extruded I guess, I don't know much about the processes there, mostly wondering about the bends as I know from steel you can break edges if you're not careful about the grain you're bending on vs how you're bending
10:01 AM Loetmichel: its not a problem with that thin stuff
10:02 AM Loetmichel: it IS a problem however with the 4mm sheets i have to bend from time to time
10:02 AM MarcelineVQ: steel goes thorough a fair number of rolling passes to get sized down so it developes a direction of more strength and a direction of less
10:03 AM Loetmichel: they tend to develope micro cracks at a sharp bend. easily avoided though by making the inner slot that defines the bend wider
10:03 AM Loetmichel: so that it has a 2mm radius
10:03 AM Loetmichel: then the 4mm sheets stay in one piece at the bends, too
10:03 AM MarcelineVQ: neato
10:58 AM Wolf: hmm, Iâ€™m tempted to take the chuck off this indexer I got and put it on a D1-4 backing plateâ€¦.
11:11 AM Loetmichel: MarcelineVQ: that vesa nick mount is made of 4mm sheet alu: http://www.cyrom.org/palbum/main.php?g2_itemId=15937&g2_imageViewsIndex=1
11:11 AM Loetmichel: .. and i even hat to "trick" a bit...
11:11 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15934&g2_imageViewsIndex=1
11:11 AM Loetmichel: ... CNC router was to small... -> http://www.cyrom.org/palbum/main.php?g2_itemId=15931&g2_imageViewsIndex=1
11:12 AM Loetmichel: :-)
11:14 AM SpeedEvil: https://i.imgur.com/a8Xu9AY.jpg?1 my current TV mount
11:14 AM SpeedEvil: Not CNCd
11:15 AM SpeedEvil: Bearings are now greased polyethlene disks, which works quite well, extends out about a meter
11:15 AM Loetmichel: SpeedEvil: nice... but i had to do something we could sell to our customer... ;)
11:15 AM SpeedEvil: yeah - this was V0 hack to see if the concept works.
11:15 AM Loetmichel: and that TV was 50" ;)
11:16 AM SpeedEvil: only 40" here
11:16 AM SpeedEvil: It's only ten kilos though
11:16 AM Loetmichel: yeah, that one was closer to 50kg
11:16 AM Loetmichel: the shielding glass in front was 13kg alone ;)
11:28 AM fragalot: I forgot the darn mesa at work again! >.<
11:28 AM fragalot: and my lunchbox :x
11:31 AM roycroft: my replacement vfd remote panel is finally arriving today
11:31 AM roycroft: and i'm impressed
11:31 AM roycroft: it left portland at 6:06am this morning, and arrived in eugene at 6:10
11:31 AM Connor: roycroft: What brand VFD ?
11:31 AM roycroft: huanyang
11:32 AM roycroft: portland is 200km from eugene
11:32 AM roycroft: so getting it here in 4 minute is very impressive :)
11:32 AM roycroft: i ordered this thing on aliexpress in november, connor, and that one still has not arrived
11:32 AM Connor: Geez.
11:33 AM roycroft: i reordered a bit over a week ago, and the replacement is finally here
11:33 AM Connor: https://www.amazon.com/gp/product/B073WWPPWG
11:33 AM roycroft: and i am at the point where i need it now
11:33 AM Connor: I got a 1.5KW version of that for my bridgeport.. So far so good..
11:33 AM fragalot: roycroft: timezones?
11:33 AM roycroft: same timezone
11:33 AM roycroft: portland is almost due north of here
11:33 AM fragalot: what are they not telling us???
11:33 AM roycroft: i think ups have some clock synchronization problems :)
11:38 AM fragalot: their clocks work fine
11:38 AM fragalot: "why is this package here?"
11:38 AM fragalot: 'oh they forgot to scan it'
11:46 AM IchGucksLive: hi
11:46 AM fragalot: hey
11:47 AM Rab: It's possible that there's no distribution center in Eugene, so once it's scanned onto the truck it's considered there.
11:47 AM roycroft: there is a large distibution center in eugene
11:47 AM Rab: ...Never mind. ;)
11:47 AM roycroft: it's just an amusing anomoly
11:48 AM roycroft: more than likely exactly what fragalot suggested
11:48 AM roycroft: it arrived in eugene and they found it had not been scanned as having left portland
11:48 AM roycroft: so it left and arrived in a very short time period
11:48 AM fragalot: roycroft: it's more fun if there are several distribution centres in between
11:48 AM fragalot: "which one do you guess this came from?"
11:48 AM gloops: Ichs, sbr bearings, 1100mm gantry, how much play would you expect either side? like hold one side, how much can the other side move before bearings start binding
11:48 AM roycroft: it took the route i did not expect, actually
11:48 AM roycroft: three distribution centers in china, to japan, anchorage
11:48 AM roycroft: all that is fine
11:49 AM roycroft: but then it went down to ontario california before coming back north to portand and then south to eugene
11:49 AM roycroft: at least it did not hang out in memphis for a while
11:49 AM IchGucksLive: gloops: the wood engraver or the plasma
11:49 AM fragalot: roycroft: classic. :)
11:49 AM gloops: router
11:49 AM roycroft: if it were fedex it would have gone form cali or alaska to memphis, back to cali, then to seattle, then portand, and finally here
11:50 AM IchGucksLive: this one http://heimwerkermarkt-tretter.de/holzcnc.jpg
11:50 AM gloops: i expected to be able to pull the gantry square - cannot, not much give at all
11:50 AM roycroft: there is a large ups distribution center in roseburg oregon, an hour south of here
11:50 AM Rab: roycroft, my sister lives in Corvallis, and I thought Eugene was smaller...I see now it's actually 3x the population.
11:50 AM roycroft: my parcels from california regularly go from cali to portland, then to roseburg, then to seattle, then back to portland, then eugene, then here
11:51 AM roycroft: yes, eugene is 3x as large as corvallis
11:51 AM roycroft: corvallis is the most educated city in oregon
11:51 AM Wolf: roycroft: sounds like the trip my air cylinder took usps, made it to DC, then went south to greensville NC, instead of 30 mins north to me last week
11:51 AM roycroft: people go to engineering school at oregon state university and never leave corvallis when they graduate
11:51 AM Rab: Corvallis is pretty podunk IMO. Not sure how they tolerate it.
11:52 AM roycroft: it has the highest percantage of the population with graduate degrees in the state
11:52 AM roycroft: also the highest percentage with bachelor's degrees
11:52 AM fragalot: roycroft: so they have 2 graduates?
11:52 AM * fragalot runs
11:52 AM gloops: people sneer at the round rails, they are no joke, pretty good fitting
11:52 AM fragalot: round rails have their place
11:52 AM roycroft: oregon is a pretty rural, redneck state generally
11:52 AM Rab: I only sneer at unsupported ones.
11:53 AM fragalot: unsupported ones can be fine too
11:53 AM roycroft: outside the portland metro area there are little islands of pregressivism in salem, corvallis, eugene, and bend, surrounded by extremely conservative rural areas
11:53 AM sync: even the supported ones are kind of eh, they are a huge bimetal element
11:54 AM roycroft: people think oregon is full of hippies and hipsters
11:54 AM gloops: they are rigid, only thing is - they came bent anyway
11:54 AM Rab: sync, that's an interesting point.
11:54 AM roycroft: hippies and hipsters do outnumber the rednecks, but we're pretty isolated from each other
11:54 AM fragalot: gloops: lol
11:54 AM roycroft: eugene is an odd place
11:54 AM gloops: got to make some shims anyway to get a few mm cant pull the gantry much on the bearings
11:55 AM roycroft: we have a twin city - springfield - that's just across the river
11:55 AM roycroft: springfield is extremely conservative
11:55 AM roycroft: crossing over i5 is like entering another world
11:56 AM roycroft: i actually like that
11:56 AM roycroft: i think it's not good when peoples with very different ideologies are isolated from each other
11:57 AM roycroft: btw, our springfield is the springfield of simpson's fame
11:57 AM roycroft: and eugene is shelbyville, of course
11:58 AM fragalot: i'm pretty sure the nuclear plant homer works at is the one here in belgium
11:58 AM Rab: Yeah? Where's your tire fire?
11:58 AM fragalot: Monorail.
11:59 AM fragalot: https://i.imgur.com/Kv68SQL.png
11:59 AM fragalot: brilliant
11:59 AM fragalot: (fake, but brilliant)
12:00 PM roycroft: we only have one nuclear power plant in oregon
12:00 PM roycroft: it's right on the columbia river, and it has never been activated
12:01 PM roycroft: it was built in the '70s and mothballed in the '80s before it ever went online
12:01 PM fragalot: ours has been de-activated many times
12:01 PM jdh: crank it up
12:01 PM Rab: roycroft, I appreciate that dynamic in Texas. E.g. I don't see many guns in the city, but gun culture is an everyday thing you can come to terms with and not some inexplicable psychosis somewhere far away.
12:01 PM fragalot: because the govt continues to say "we'll shut you down"
12:01 PM fragalot: so they have stopped investing in them for ~30 yrs
12:01 PM fragalot: and each time the close date is there, the contract is extended
12:01 PM roycroft: we don't want them and we don't need them
12:02 PM roycroft: i have no idea why that plant was ever built
12:02 PM roycroft: we have cheap hydroelectric power
12:02 PM roycroft: the nuclear plant could never have produced power that was cost competetive with our hydro power
12:02 PM roycroft: and we're a net exporter of electricity
12:02 PM fragalot: we have expensive wind (expensive due to the false costs reported to drive up subsidies)
12:02 PM roycroft: we send a lot of our power to california
12:09 PM * JT-Shop keeps looking a table saws...
12:09 PM fragalot: i've given up tryihng to find a good one
12:09 PM roycroft: get a sawstop if you can afford it
12:09 PM fragalot: either they don't fit AT ALL, or they're 10k+
12:10 PM fragalot: (and also don't fit)
12:10 PM fragalot: or they are utter shite like my bosch i have now
12:10 PM fragalot: where someone decided it would be a good idea to emboss the logo in the table and sand it smooth
12:10 PM fragalot: not to mention the wobbly spindle
12:10 PM fragalot: </rant>
12:11 PM JT-Shop: sawstop?
12:12 PM fragalot: JT-Shop: they actually have a pretty nice saw
12:12 PM fragalot: works well, and has a nice feature that prevents you cutting your fingers off
12:12 PM fragalot: completely
12:12 PM JT-Shop: oh the blade stop thing
12:12 PM fragalot: yes
12:12 PM JT-Shop: yea my neighbor has one and it saved him from a nasty cut
12:13 PM fragalot: I don't think they sell 'm in europe sadly.. wouldn't mind one
12:18 PM MarcelineVQ: are you talking about that fin that comes up behind the blade?
12:19 PM fragalot: MarcelineVQ: saw-stop shoots a solid block of aluminium into the blade to stop it when it senses your fingers touch the blade
12:19 PM JT-Shop: no, it's a device to instantly stop the blade if contact with skin is detected
12:19 PM fragalot: what you're talking about is a riving knife
12:19 PM MarcelineVQ: huh, senses the capacitance of your hand I suppose?
12:19 PM fragalot: MarcelineVQ: exactly
12:19 PM MarcelineVQ: very cool
12:20 PM JT-Shop: the one my neighbor has is single use only and must be returned to the factory for a free replacement
12:20 PM fragalot: oh neat
12:20 PM fragalot: does it have to be in the original box? :P
12:22 PM JT-Shop: no, you just have to tell them it saved you from bleeding out and they replace it
12:22 PM roycroft: sawstops work brilliantly
12:22 PM roycroft: and you do not need to send it back to the factory if it's triggered
12:22 PM roycroft: you can buy a replacement stopping mechanism
12:23 PM roycroft: in fact, if you use a dado set you can buy a dado brake for it
12:23 PM roycroft: the thing just plugs into the saw
12:23 PM fragalot: can't use dado sets in europe
12:23 PM roycroft: the original sawstop had to be returned to the factory for repair
12:23 PM roycroft: but the current models have user-installable replacement brakes
12:23 PM fragalot: unless if you get a special saw equipped for dado sets with pins & a larger brake resistor
12:23 PM roycroft: iirc the brake is about $100 12:24 PM roycroft: but since the saw just saved you from cutting your finger off you'll be happy to spend the$100 to get it working again
12:24 PM * JT-Shop stops looking at table saws and goes back to work...
12:24 PM JT-Shop: I gladly pay $100 to not get cut again on a table saw 12:25 PM roycroft: yes 12:25 PM roycroft: you pay a premium up front to get the saw 12:25 PM roycroft: but it's well worth it imo 12:25 PM roycroft: that said, i don't have one yet 12:25 PM roycroft: it's on my list though 12:25 PM fragalot: agreed, especially because the saw itself is pretty good too 12:25 PM roycroft: yes, it's a great saw 12:26 PM MarcelineVQ: nice to have those sort of features these days, table saw is the second most dangerous tool in the shop 12:26 PM JT-Shop: the video on sawstop's web page is impressive 12:26 PM roycroft: next to the box cutter 12:26 PM fragalot: roycroft: no. 12:26 PM roycroft: which is the single most dangerous tool in industry 12:26 PM fragalot: the most dangerous tool in the shop is you. 12:26 PM MarcelineVQ: the box cutter is also the second most dangerous tool in the shop :> 12:27 PM roycroft: accident statistics bear that out year after year 12:27 PM fragalot: I maintain the only reason knives or box cutters are dangerous is because people let them get dull 12:28 PM roycroft: dull knives are inherently more dangerous than sharp ones 12:28 PM roycroft: there is no doubt about that 12:28 PM fragalot: s/only/main/ 12:28 PM MarcelineVQ: Also posibly that they're dangerous because jobs that use them are tedious and tedium leads to lack of attention 12:28 PM roycroft: but i would suggest that it's also in large part because they are small and people are not trained to use them properly 12:29 PM fragalot: roycroft: agreed. 12:29 PM roycroft: they do not make lots of noise and do not weigh hundred/thousands of kg 12:30 PM Roguish: Bosch makes a 'safety' table saw also. https://newatlas.com/bosch-reaxx-table-saw/36636/ 12:30 PM sync: fragalot: there is no reason why you could not use them in europe 12:31 PM roycroft: one can't use a riving knife with a dado set 12:31 PM sync: it is frowned upon by the osha equivalents but nothing actually stops you 12:31 PM fragalot: sync: not on standard saws 12:31 PM Roguish: a bit pricey, but after touching a blade once, you'll appreciate the value. been there, done that. no fun. 12:31 PM roycroft: although not applicable 12:31 PM fragalot: sync: MOST saws just do not have the required spindle length to run them 12:31 PM roycroft: since dadoes by definition are not through cuts 12:32 PM fragalot: and the ones that come factory rated to run them typically have additional features to allow dado sets, such as driving pins and larger braking mechanisms 12:32 PM roycroft: if the saw is set up properly there is no chance of getting injured using a dado set 12:32 PM roycroft: most table saws sold in the us have spindles long enough for a dado set that can cut up to 18mm wide 12:33 PM fragalot: most table saws here (read: nearly all) can't hold more than a single blade 12:33 PM roycroft: i'm glad to see that bosch saw 12:33 PM roycroft: one reason i think that osha don't require sawstops is that it's a patented technology that is not licensed 12:33 PM roycroft: and giving sawstop a monopoly would be problematic 12:34 PM roycroft: now there are two technologies that have the same effect 12:34 PM roycroft: that makes it time to start working on regulations to require such a safety feature in industry 12:34 PM fragalot: roycroft: actually 12:34 PM fragalot: bosch is NOT currently selling or marketing the rEAXX saws 12:34 PM roycroft: oh 12:35 PM fragalot: likely due to patent issues 12:35 PM roycroft: well whenever they're ready it will be time :) 12:35 PM fragalot: it depends on what sawstop patented 12:35 PM roycroft: hmm 12:35 PM fragalot: if they also patented the detection mechanism, others will be hard pressed to find an alternative to capacitive sensing 12:35 PM roycroft: the "don't let the blade cut you" mechanism is completely different from sawstop's 12:35 PM roycroft: but the detection mechanism could be infringing 12:36 PM roycroft: but if that is the case then it's foolish for sawstop to refuse to license the detection mechanism 12:36 PM roycroft: licensing it would increase sawstop sales 12:36 PM IchGucksLive: hi cp 12:36 PM fragalot: or they could not come to an agreement on the terms 12:37 PM IchGucksLive: hi CP_Away 12:37 PM fragalot: bosch is likely to play the "we're bigger" card 12:37 PM roycroft: sawstop are doing pretty well 12:37 PM roycroft: but yes, orders of magnitude smaller than bosch 12:38 PM fragalot: I'll just make my own table saw 12:38 PM fragalot: with blackjack, and hookers 12:38 PM IchGucksLive: CP_Away: = x.coder 12:38 PM roycroft: that press release for the bosch is dated 2015, with a target availability of later that year 12:38 PM roycroft: and a target price of$1500, which is competetive with the low-end sawstop
12:38 PM fragalot: roycroft: bosch's website states they do not offer them.
12:38 PM roycroft: so terms may be the issue
12:38 PM roycroft: and they thought at the time they were close to an arrangement
12:38 PM fragalot: could be
12:39 PM fragalot: or they got sued
12:39 PM fragalot: and it's still on-going, or they lost
12:39 PM IchGucksLive: German NewsPressh has named DT Word of the year 2017 AltenativeFacts
12:39 PM fragalot: IchGucksLive: what?
12:40 PM Roguish: SawStop tried for years to get othere companies like Delta to use the tech. no one wanted it, or wanted to pay. so SawStop went to market solo.
12:40 PM IchGucksLive: not to be discussed
12:40 PM roycroft: actually, that article suggests that bosch use a different detection mechanism
12:40 PM roycroft: yes, i recall that, roguish
12:40 PM IchGucksLive: fragalot: is mashine moving n manuell push
12:40 PM roycroft: they developed a prototype, and their business model was to license the technology to other manufacturers
12:40 PM fragalot: what machine?
12:41 PM sync: isn't the sawstop old enough that the patents ran out by now?
12:41 PM IchGucksLive: your room fit
12:41 PM roycroft: no
12:41 PM roycroft: patents in the us are for 17 years
12:41 PM roycroft: and sawstop is not that old
12:41 PM roycroft: maybe 10 years
12:41 PM roycroft: oh
12:41 PM roycroft: teh wikipedia claim they formed the business in 1999
12:41 PM IchGucksLive: roycroft: you can pay for 50years
12:41 PM Roguish: and can be extended with 'updates' and 'improvements'
12:42 PM roycroft: prototype in 2000, license attempts in 2002
12:42 PM fragalot: IchGucksLive: I have no idea what you mean -- could you say it in german? (I can read german, just not reply :))
12:42 PM IchGucksLive: roycroft: and if it is a Brandown it is expandable
12:42 PM Connor: My Maker Space has a SawStop. It's went off about 5 times now.. not once for a finger though.. a few times due to damp wood or the aluminum saw guide..
12:42 PM IchGucksLive: fragalot: just forget it
12:42 PM fragalot: ok
12:43 PM roycroft: and there is active patent litigation
12:43 PM roycroft: the sawstop patents exire in 2021
12:43 PM fragalot: can they be renewed?
12:43 PM roycroft: all according to teh wikipedia
12:43 PM roycroft: patents cannot be renewed
12:43 PM fragalot: k
12:44 PM IchGucksLive: fragalot: https://de.wikipedia.org/wiki/Unwort_des_Jahres_(Deutschland)
12:44 PM fragalot: IchGucksLive: I just didn't know what you meant with "DT word"
12:44 PM IchGucksLive: Doneld the worlts best men
12:45 PM fragalot: ah right :D
12:45 PM roycroft: because every time the copyright on mickey mouse is about to expire our congress pass a law extending it further
12:45 PM roycroft: and it is illegal to pass a law that applies to one company/individual
12:45 PM IchGucksLive: nice Wall examples in the desert build at 450Mio
12:45 PM roycroft: so that extension applies to everyone
12:46 PM fragalot: roycroft: unless if that one company belongs to potus?
12:46 PM IchGucksLive: roycroft: im not shure you where right
12:46 PM fragalot: or is written in such a way that it COULD be generic, but actually isn't
12:46 PM roycroft: speaking of which, my friend who works at the university of oregon said that disney attempted to go after the university again
12:46 PM roycroft: they do this every few years
12:47 PM roycroft: some new hot shot attorney for disney decides to sue the u of o for copyright infringement, because the u of o's mascot is donald duck (the teams are the oregon ducks)
12:47 PM IchGucksLive: roycroft: washingmashines in the USA are most toploader as the Front is on German patent
12:47 PM roycroft: so every few years the u of o's legal staff pull out the letter written by walt disney himself granting the university permission to use donald duck
12:47 PM IchGucksLive: this is the patent gab
12:48 PM roycroft: most of our washing machines are front loaders now
12:48 PM roycroft: because they're so much more efficient
12:48 PM fragalot: because the patent expired :D
12:48 PM roycroft: and most of our frontloaders do not come from germany, but from south korea
12:48 PM roycroft: we don't care about german patents
12:48 PM roycroft: germans can patent things in the us
12:49 PM roycroft: and we respect those
12:49 PM roycroft: but if germans patent things in germany and neglect to patent them in the us we don't care
12:50 PM IchGucksLive: COOL DonaldDuck the disney DrawingFigure has its own Patent shop in real live
12:51 PM IchGucksLive: so the Danish MEN how brought up the sunken ship with pingpongballs had to pay as he used the idee
12:51 PM * fragalot only just made the mental link on how to pronounce IchGucksLive's name >.<
12:51 PM fragalot: IchGucksLive: really?
12:51 PM IchGucksLive: let me see if it is on keyboard :P
12:54 PM DocHopper: Hey there linux CNC-ers, I've been 3d printing for some time now, but would like to get into using a small mill to do some PCB/Acrylic/Aluminum work. Does anyone have a good suggestion for a very low cost cnc mill with which I can do some basic work and experimentation?
12:54 PM fragalot: DocHopper: where do you live?
12:54 PM IchGucksLive: DocHopper: where in the world are you
12:55 PM IchGucksLive: DocHopper: what size do you expect or what budget
12:57 PM gloops: china produces 30 million washers a year
12:57 PM IchGucksLive: gloops: without a patent shield
12:58 PM gloops: UK is also making washers again Ichs
12:58 PM IchGucksLive: mainly there are the same parts in as in BEST buy
12:58 PM DocHopper: IchGucksLive: fragalot I'm in the US, and this is only an introductory project, so less than $500 would be ideal. 12:58 PM IchGucksLive: gloops: they have been offert a big deal today 12:59 PM gloops: https://www.which.co.uk/news/2015/11/new-british-made-washing-machine-brand-launches-421411/ 12:59 PM gloops: ill buy an ebac when ours goes, i dont even know what make ours is lol 12:59 PM roycroft: and soon the uk will have no foreign market for them :) 12:59 PM * roycroft pokes gently but will not react to a counterpoke today 01:00 PM gloops: you think europe is the only market roy? 01:00 PM gloops: heh heh 01:00 PM roycroft: when i bought my current washer/dryer i was looking at a blosch set 01:00 PM IchGucksLive: DocHopper: http://stores.ebay.com/rattmmotor88/CNC-Router-Machine-/_i.html?_fsub=2760685619 01:01 PM roycroft: but they were way more expensive than the mitsubishi that i finally got, and the bosch were rated as much less reliable by consumer reports 01:01 PM DocHopper: IchGucksLive: So most of the Chinese grbl based aluminum machines would serve me alright? 01:02 PM IchGucksLive: yes 01:02 PM fragalot: DocHopper: good enough to start out with 01:02 PM fragalot: they are all very light duty, but at that price range you won't find much better 01:02 PM gloops: someone selling a router in the UK Â£800, not bad size either 01:03 PM fragalot: gloops: link? 01:03 PM gloops: belt drive though 01:03 PM fragalot: never mind. :D 01:03 PM gloops: https://www.facebook.com/photo.php?fbid=10155384172787297&set=pcb.1828242083894188&type=3&theater 01:04 PM gloops: actually would need some sorting out i think 01:04 PM DocHopper: fragalot: Thanks, that really all I need. At this point it's mostly a toy. There may be a point whenm I look at a full size 4x8 mill, but I don't have the space for now. 01:04 PM fragalot: need to log in to see that, gloops :( 01:04 PM fragalot: DocHopper: :-) 01:04 PM gloops: ahh, its on diy cnc machines, looks about 6-7foot long, 4 foot wide maybe 01:05 PM gloops: i do see them on ebay now and again, you could maybe get more for the money used 01:07 PM DocHopper: fragalot: And what should I expect to be using for path generation and sending the code to a machine like that? Have a good primer? 01:07 PM gloops: https://www.ebay.co.uk/itm/6040-Cnc-Router/183017423747? 01:07 PM fragalot: I personally use Fusion360 on mine, and used to use Vectric Cut2D before that 01:07 PM fragalot: but there are thousands of options 01:07 PM IchGucksLive: FreeCAD 01:08 PM IchGucksLive: maybe NEW release within ths wek 01:08 PM IchGucksLive: as Yesterday Featherclosed 01:09 PM IchGucksLive: my dressup dident make it BAD 01:09 PM Rab: DocHopper, do you expect to focus on 2D (cutting from sheet stock) or 3D (contouring)? 01:10 PM IchGucksLive: im off Gn8 From Germany 01:10 PM fragalot: bye IchGucksLive 01:10 PM DocHopper: Rab: I didn't realize contour was much of an option on a machine that small. Likely 2d initially, but as I gain some experience, I'll be moving to contouring (But never organic shapes). 01:11 PM gloops: for wood - the Vectric apps, v carve, aspire 01:11 PM gloops: freecad probably as good as anything for simple forms, i cant vouch for the pathing on that though 01:12 PM gloops: f engrave is a free v carve app, no frills but good enough 01:13 PM DocHopper: gloops: So which should I look at first? This is all open source stuff? 01:13 PM Rab: DocHopper, lots of 2D options. I use Inkscape and gcodetools for 2D and engraving; there are some quirks but it's productive. 01:13 PM gloops: the vectric apps arent free, aspire is Â£1500 01:13 PM gloops: DocHopper go with fusion 360 or Freecad 01:14 PM gloops: i dont like fusion as it is cloud based and you have to sign up for it, but it is a good app 01:14 PM DocHopper: gloops: I'm not okay with fusions remote requirements, so I guess I'll look at freecad. 01:14 PM phipli: Does Fusion 360 work with linux yet? 01:14 PM jthornton: never will 01:14 PM phipli: the did a trial... 01:14 PM gloops: Freecad - download, install no nonsense no questions, nice app to learn on, can do a lot 01:14 PM phipli: sigh 01:15 PM phipli: I have Freecad 01:15 PM jthornton: https://elinux.org/RPi-Cam-Web-Interface 01:16 PM jthornton: phipli: finally found a camera interface for the rpi camera and it just works out of the box with no crap about loading a zillion libs lol 01:16 PM * roycroft is not looking forward to finding cam software when the time comes 01:16 PM jthornton: now to figure out a box to put the egg camera in...\ 01:16 PM roycroft: my life might involve a lot of hand-coded gcode 01:16 PM phipli: thanks JT 01:17 PM phipli: my dad was looking for something like that 01:17 PM jthornton: I've been looking for a week lol 01:17 PM phipli: he has a pi attached to an 8" telescope pointing at a Red Kite's nest. 01:17 PM jthornton: that will work perfect for that 01:18 PM jthornton: so long as it is the pi camera and not a usb camera 01:18 PM phipli: yeah, tis 01:18 PM * fragalot just installed freecad to give it a go 01:19 PM phipli: roycroft, there is pycam 01:19 PM phipli: slow though 01:19 PM roycroft: i think i looked at that, phipli 01:19 PM roycroft: i use autocad 2008 and solidworks 2012 for cad software 01:19 PM xunil: hi folks, hoping someone has an idea for me... helping a friend with a scratch-built CNC plasma cutter backed on LinuxCNC; he wants to have a Z-up and Z-down switch for manual material touch-off. hooking up a button to the Z axis jog in HAL is pretty straightforward but he wants it to be at a fixed (slow) jog speed every time he uses the Z-up/Z-down buttons, but not have it affect the UI jog speed 01:19 PM gloops: it isnt solidworks fragalot but it is useful 01:19 PM jthornton: roycroft: on my lathe I do 99% of the ops using ngcgui 01:19 PM roycroft: i've not heard of that, jthornton 01:19 PM roycroft: i'll check it out 01:20 PM xunil: has anyone done something like this before? 01:20 PM phipli: roycroft, if your carving pretty things for customers, image-to-gcode is easy 01:20 PM roycroft: oh, that's some of the stuff that's bundled with linuxcnc 01:20 PM roycroft: my first cnc machine will be a mill/drill 01:20 PM roycroft: and i'll not be doing carving with it 01:20 PM phipli: turns a greyscale depth map into gcode 01:20 PM jthornton: http://gnipsel.com/files/chnc/subroutines/ 01:20 PM roycroft: some engraving, mayhap 01:20 PM roycroft: but mostly "standard" milling of parts 01:21 PM phipli: I was using freecad and processing it with pycamm 01:21 PM phipli: *cam 01:21 PM fragalot: xunil: I would imagine this should be possible using one of the velocity overrides? 01:21 PM phipli: but I'm making it up as I go along 01:22 PM jthornton: I have a G code generator for holes and tapping and such, also there are simple G code generators for most things like engraving and other mill tasks 01:22 PM phipli: someone who actually does it for a job might give better advice... well. most people will. I just play. 01:22 PM gloops: not seen that http://www.ncplot.com/ 01:22 PM xunil: fragalot, OK, something for me to look at - I'm familiar with the Axis GUI and using the sliders in that but I don't know how that's hooked up on the HAL side. 01:22 PM roycroft: i don't care about performance of the cam software right now 01:22 PM gloops: g code ripper is handy, splits files, you can double the size of your machine capacity 01:22 PM phipli: jthornton, the linuxcnc site has a load of simple python tools for thing slike pockets, counterbores and speaker grilles 01:23 PM phipli: which I found handy 01:23 PM roycroft: if it's too slow for me i can always through more cpu and memory at it :) 01:23 PM gloops: it also does wrapping - gives code for 4 axis indexing 01:23 PM phipli: (I imagine you know they're there) 01:23 PM xunil: fragalot, I had also considered using a mux to select between the UI-configured jog speed and a fixed, low jog speed, with the mux selector hooked up such that when the Z physical button is pressed it selects the slow jog from the mux 01:23 PM jthornton: xunil: ignore the joypad part and look at the jogging part http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant 01:23 PM xunil: but i think you have to set the halui.jog-speed either way, and i think that once you set that you lose whatever is set in the Axis UI 01:24 PM xunil: i should play with a sim i guess 01:24 PM xunil: jthornton, cool, more ideas, just what I was after :) 01:24 PM jthornton: np 01:25 PM * jthornton is done with yogurt break so back to trying to make some channel rings actually sorta round... 01:25 PM xunil: ok yeah, this uses a mux 01:25 PM xunil: i was on the right track :) 01:25 PM phipli: jthornton, angle grinder? 01:26 PM phipli: that will get them sorta round :) 01:27 PM gloops: plastic on TV again, amount of waste, what we need is a system for turning old plastic bags into high profit items with no work involved 01:27 PM gloops: except operating the till 01:28 PM roycroft: or maybe not use plastic bags any more? 01:28 PM xunil: my county outlawed the use of them 01:28 PM roycroft: the city of eugene has banned them 01:28 PM xunil: but it's California, everything's illegal here :) 01:29 PM gloops: well i hate the amount of plastic wrapping used on foodstuffs, everything doesnt need to be inside a plastic tray with a plastic film im sure 01:29 PM gloops: but a lot could be recycled im sure 01:29 PM roycroft: i boycott stuff that is gratuitously wrapped in plastic 01:29 PM roycroft: most plastic cannot be recycled 01:29 PM roycroft: much of it can be downcycled 01:30 PM gloops: melt it down and make roads with it or something useful 01:30 PM roycroft: that's just pushing the problem into the future 01:30 PM JT-Shop: phipli: 8 ton jack 01:30 PM roycroft: not as bad as dumping it in the ocean and killing sea life though 01:30 PM gloops: plastic is ok if its re-useable, its the once only stuff thats doing the harm 01:31 PM gloops: just keep it in a form that can always easily be re-used 01:31 PM roycroft: yes, but as i said, most plastics cannot be recycled like that 01:31 PM MarcelineVQ: aluminum wrap makes vegetables last longer than plastic as well 01:31 PM roycroft: we could shift to plastics that can, but we don't 01:32 PM roycroft: buying vegetables fresh and using them right away is even better 01:32 PM MarcelineVQ: especially celery for some reason, which gets at least a month of fridge time extension simply by double wrappign in alu 01:32 PM gloops: i grow most of my own 01:34 PM phipli: Snowing in Scotland 01:35 PM gloops: was snowing fast here earlier, didnt settle though 01:35 PM * phipli checks the weather in case it is heading this way... 01:35 PM phipli: 3am, some snow tonight 01:35 PM phipli: birds won't like that 01:35 PM phipli: should get some snow chains for my bike 01:35 PM fragalot: freeCAD's "Path" scares me. 01:36 PM gloops: .16? 01:36 PM fragalot: yes 01:36 PM fragalot: using plastic to make roads is a terrible idea 01:36 PM fragalot: driving on it tears small particles off 01:36 PM fragalot: which make their way into the runoff water when it rains 01:37 PM fragalot: which just ends up in the ocean anyhow 01:37 PM -!- #linuxcnc mode set to +v by ChanServ 01:37 PM gloops: well i dont know, roof sheets, for people with no houses 01:37 PM gloops: there must be some substantial application for it, wont happen because theres no cash in though, as we know 01:37 PM roycroft: not to mention that traditional hardscaping causes erosion and contributes to localised flash flooding 01:37 PM phipli: stop making things out of really thin plastic to actually take advantage of its durability? 01:37 PM fragalot: if you can make it reliably UV resistant 01:38 PM phipli: double the thickness and make it last forever 01:38 PM phipli: (said no business man ever) 01:38 PM roycroft: newer road technologies use permeable materials so that roads can absorb water and not shed it all 01:38 PM gloops: phipli yes thats the other thing, make the product re-useable 01:38 PM fragalot: roycroft: the water still goes somewhere. :P 01:38 PM roycroft: yes, back into the ground below the road 01:38 PM gloops: fencing 01:38 PM roycroft: instead of off to the side of the road to join all the other water that is there 01:39 PM phipli: https://www.youtube.com/watch?v=32iSeAYnbI8 01:39 PM fragalot: gloops: not only make it reusable, but then also re-use it! 01:39 PM fragalot: I can't even count how many "re-usable" bags I have 01:39 PM fragalot: just because I had to buy a new one because I forgot the old one 01:39 PM roycroft: my "reusable" bags are canvas 01:40 PM gloops: who uses these strong bags they sell at suprmarkets - probably 5% 01:40 PM roycroft: most of them i've had for 15-20 years 01:40 PM MarcelineVQ: fragalot: haha ditto, they make good seperators for items in a deep freezer luckily 01:40 PM roycroft: i've been bringing my own bags to market for almost 40 years 01:40 PM roycroft: it's easy to not forget them 01:41 PM roycroft: when you get home from market and put your stuff away, hang the bag on the front doorknob 01:41 PM gloops: they used to use shopping baskets here, willow grows fast, consumes co2, cleans the river - but no, that was old fashioned and you cant put the brand name on a basket 01:41 PM roycroft: next time you leave the house it will be right there and you won't be able to forget it 01:41 PM roycroft: put it back in the car when you go out 01:41 PM fragalot: roycroft: I often go to the shop on my way home from work 01:41 PM fragalot: bag is in the car 01:41 PM fragalot: I'm in the shop 01:41 PM fragalot: no bag. 01:41 PM roycroft: go out and get it :) 01:41 PM fragalot: I can't help being an idiot :) 01:42 PM gloops: roy nobody ever does they, they throw the shopping in the cupboard and start troughing what they bought lol 01:42 PM roycroft: actually, i'm very forgetful 01:42 PM roycroft: i've learned to develop habits so that i don't forget 01:42 PM fragalot: I usually use crates to go shopping now 01:42 PM Tom_L: roycroft how are they working out for ya? 01:42 PM roycroft: some folks think that all my habits are constraining 01:43 PM roycroft: and think it must drive me nuts 01:43 PM gloops: discount shop here doesnt sell bags - just keeps a stock of old cardboard boxes 01:43 PM fragalot: but when i'm out buying DIY stuff or unplanned trips,.. I add to the bag collection 01:43 PM roycroft: i find them liberating 01:43 PM CaptHindsight: I use the plastic ones they sell you at the market. I use them later to wrap toxic waste before disposal. 01:43 PM fragalot: gloops: most food shops do that here, actually 01:43 PM roycroft: when i develop a good habit and imprint it really well it's something i never have to think about again 01:43 PM MarcelineVQ: I use them as gloves to pick mushrooms, then I just invert it and tie 01:44 PM roycroft: as a tiny example, people tend to not use turn signals unless they determine that there is a compelling reason to do so 01:44 PM roycroft: i'm sure all of us have experienced folks who are stopped at a signal light with no indicator on 01:44 PM roycroft: as soon as we approach from behind the car starts indicating 01:45 PM roycroft: the driver obviously decided that it would be prudent to indicate because someone is behind 01:45 PM roycroft: my habit is to indicate whenever i turn 01:45 PM fragalot: so what roycroft does instead, is indicate at all times. 01:45 PM fragalot: :P 01:45 PM roycroft: even at 3am in the middle of nowhere, where the nearest car is probably 10 km away 01:45 PM Tom_L: i just leave mine on all the time. eventually i will turn that direction :D 01:45 PM roycroft: and i've had passengers get on my case about it 01:45 PM CaptHindsight: have you noticed the new cars that turn on the back up lights after the vehicle is turned off? 01:45 PM roycroft: but it's a habit 01:45 PM roycroft: i don't think about it, EVER 01:45 PM roycroft: when i turn i indicate 01:46 PM roycroft: no judgement, no evaluation of the situation 01:46 PM roycroft: it's just a habigt 01:46 PM fragalot: I find that a bad example to have to explain 01:46 PM roycroft: why? 01:46 PM fragalot: because turning == signal 01:46 PM fragalot: regardless of the situation 01:46 PM CaptHindsight: they act like they are going to back out from their parking space but have really just turned off the ignition, who had this genius idea? 01:46 PM roycroft: i've had people very aggressively harass me for indicating when there is nobody around 01:46 PM fragalot: the fact that that is even a discussion annoys me 01:47 PM Tom_L: CaptHindsight was it a toyota product? 01:47 PM roycroft: i think it's a good example 01:47 PM fragalot: CaptHindsight: or the volkswagens using the foglights as a turning light 01:47 PM roycroft: given the context of the discussion 01:47 PM fragalot: always looks like they ahve a light out 01:47 PM Tom_L: some mfg come up with the dumbest shit sometimes 01:47 PM fragalot: roycroft: not really 01:47 PM roycroft: i was discussing how i find developing habits like that liberating, vs constraining 01:48 PM fragalot: nobody is going to say "leave that bag home you may not need it at the shop" 01:48 PM * Tom_L comes back when the discussion is more OT 01:48 PM CaptHindsight: Tom_L: GM 01:48 PM fragalot: Tom_L: we can do one better 01:48 PM fragalot: the discussion can go OTT. 01:48 PM Rab: CaptHindsight, I expect it's to illuminate the area, same as leaving the headlights on for a time. But I also think it's bad UI. 01:48 PM roycroft: to my mind, having to think about whether indicating is necessary or not (disregarding the legal requirement to do so ) is a distraction that limits my freedom to think about other things 01:49 PM roycroft: some think it infringes on their freedom to do something like that automatically instead of choosing on a case-by-case basis 01:49 PM Tom_L: CaptHindsight i hate their 'auto stop' feature 01:49 PM roycroft: and perhaps that's correct 01:49 PM CaptHindsight: so now backing up and indicating where your car is are the same 01:50 PM roycroft: but i'd rather be "free" to do things more meaningful than deciding when to indicate or not 01:50 PM MarcelineVQ: brilliant 01:50 PM CaptHindsight: why not have them flash if you really need to see where your car is? 01:50 PM fragalot: CaptHindsight: it's to see where you are going, rather than seeing where the car is 01:51 PM * roycroft thinks that discussing user interfaces is somewhat on-topic regardless of the interface 01:51 PM fragalot: I found the "I'll keep the headlights on for a minute" feature very useful at times when parking in ocmpletely unlit areas 01:51 PM gloops: freecad .17 is improved a lot, the daily build has everything but marked as unstable 01:51 PM CaptHindsight: fragalot: then why are they on when the car is off? 01:51 PM roycroft: it's at least as far off-topic as a lot of discussions here :) 01:51 PM fragalot: gloops: yeah 'ill wait for that one to come out & try it again 01:51 PM roycroft: the headlights turn off when i remove the ignition key 01:52 PM roycroft: but i can see leaving them on for a minute as a useful feature 01:52 PM CaptHindsight: fragalot: are they supposed to be like a flashlight for the people walking away from the vehicle? 01:52 PM fragalot: but it's still intimidating with absolutely NO defaults set for you, and no preview or sim (in .16 that I could find) 01:52 PM fragalot: CaptHindsight: Yes. 01:52 PM roycroft: say you come home from market at night and you do not have an outside light that turns on automatically 01:52 PM fragalot: worked a treat for me in my old rental house that had a long unlit driveway 01:52 PM roycroft: your car headlights can provide enough illumination to get you to your front door and insert the key 01:52 PM roycroft: unless you back into your driveway like i do :) 01:53 PM CaptHindsight: fragalot: was this from the same people that develop web pages and most phone apps? 01:53 PM JT-Shop: my guess it will be Thursday before UPS delivers my packages they have had on the truck since last Thursday 01:53 PM roycroft: in which case 01:53 PM roycroft: your reversing lights could provide that illumination! 01:53 PM fragalot: CaptHindsight: *shrug* it's a setting you can disable. 01:53 PM fragalot: mine's set to illuminate if I press the lock or open button twice 01:53 PM fragalot: holding the button opens or clsoes the windows 01:54 PM CaptHindsight: fragalot: idiots can't do this, or be expected to turn them off 01:54 PM roycroft: i never turn the lights off on my car 01:54 PM Rab: CaptHindsight, it's from exactly the same people who develop touchscreen vehicle interfaces with no tactile feedback. 01:54 PM miss0r: I have a new favorite stock material on the lathe: teflon :D 01:54 PM roycroft: it has drl, so i would not be able to turn the headlights off anyway while driving 01:54 PM fragalot: miss0r: did you get the chips to break? 01:54 PM miss0r: lol 01:54 PM fragalot: miss0r: no, really? :P 01:55 PM gloops: the problem is, mankind has already invented all the things necessary for civilisation, now all we do is make gadgets and toys 01:55 PM roycroft: and i think that even during the day, having tail lights and side marker lights can provide an extra margin of visibility, hence safety 01:55 PM miss0r: I don't know of anyone who realy does that? 01:55 PM gloops: we've lost the pioneering spirit because we dont need it 01:55 PM roycroft: and the lights turn off automatically when i remove the ignition key, so i can never drain the battery with them on 01:55 PM miss0r: I placed a bucket, and just let it draw itself in there 01:55 PM miss0r: damn it! coffee got cold - having too much fun 01:55 PM CaptHindsight: gloops: you callin back up lights that stay on when you leave the car is unnecessary?

03:41 PM MarcelineVQ: sure, that an everything that was cool in the 80's 03:45 PM gloops: that kind of stuff will happen, something really revolutionary that wipes out swathes of old tech like a mass extinction 03:47 PM gloops: computers atm are a bit like early flight in balloons - flying yes, but the real stuff is yet to come 03:48 PM CaptHindsight: I want sidewalks that talk and are dible 03:48 PM CaptHindsight: edible 03:49 PM CaptHindsight: or the everything app 03:49 PM CaptHindsight: an app to replace all the other apps 03:49 PM CaptHindsight: it just does everything 03:49 PM gloops: why not have an environment that simply reads the wishes of whoever is in it and reconfigures itself accordingly 03:50 PM CaptHindsight: not sure if that would work 03:50 PM CaptHindsight: what if you have no wishes 03:51 PM MarcelineVQ: the wish fullfillment machine is what sank atlantis! :> 03:51 PM gloops: it provides the standard, you would have to want it to be different for it to change 03:52 PM gloops: you wont have to program it or command it, it will know before you 03:56 PM Deejay: gn8 03:58 PM gloops: atlantis is off the coast of the UK i think 03:59 PM roycroft: it is 03:59 PM roycroft: ask donovan :) 03:59 PM MarcelineVQ: everything is off the coast of the empire :> 03:59 PM gloops: well, in the atlantic 04:00 PM MarcelineVQ: as far as legends go I think atlantis is, atlanic go figure, and the 'lost land' of the pacific is mu 04:00 PM gloops: never heard of mu 04:01 PM MarcelineVQ: there's also lemuria to add to the lost land list 04:04 PM CaptHindsight: saw this documentary when i was a kid http://landofthelost.wikia.com/wiki/Land_of_the_Lost_Wiki 04:04 PM MarcelineVQ: hehe 04:05 PM gloops: dont think we got that here, we got lost in space 04:06 PM CaptHindsight: hundreds of$ were spent on the special effects https://www.youtube.com/watch?v=T3Qehtte0bQ

04:07 PM gloops: the waves and flames are always proportionately sized
04:40 PM gloops: Turpin family looks slightly unconventional
04:40 PM Sabotend_ is now known as Sabotender
05:47 PM Wolf: fucking amazing, some people are idiots, no wonder the package took so long and was almost lostâ€¦ https://imgur.com/a/5pi0T
05:48 PM MarcelineVQ: what the shits
05:48 PM Wolf: box was so messed up that I scratched the top on the new work station I just got in the door also
05:49 PM MarcelineVQ: how many seperate vehicles doe sone package fall off to look like that
05:49 PM Wolf: 40lb air cylinder packed in a toaster box with one crumpled news paper for packing material
05:50 PM MarcelineVQ: who's this from?
05:50 PM Wolf: eBay...
05:50 PM MarcelineVQ: aw :(
05:50 PM Wolf: probably mauled by the auto sorter
05:51 PM MarcelineVQ: as far as I've heard ebay has good buyer protection, you gonna take advantage of that?
05:51 PM Wolf: seeing nothing was stopping the cylinder from moving around the box
05:51 PM Wolf: going to yell at the seller and see what they say
05:51 PM MarcelineVQ: iirc somenone here kept getting bit by buyers making stuff up
05:52 PM MarcelineVQ: so hopefully that translates into something useful for legitimate claims

05:53 PM Wolf: looked unused in the ad pics

06:28 PM roycroft: but i do not want to have to install and uninstall it all the time
06:28 PM roycroft: hopefully the hf ones are about the same size as the mitutoyo, as i'll be using the mitutoyo for now
06:28 PM roycroft: i need to make the holder for it today
06:30 PM roycroft: just in case, i should probably make the indicator mount adjustable
06:36 PM roycroft: well yay
06:37 PM roycroft: ups just arrived, and a remote control panel for my vfd finally arrived
06:44 PM skunkworks_: wonder what happened to les watts.

08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Belt_Guard/Belt_Clearance.jpg
08:57 PM roycroft: the new vfd remote control panel will not fit in the control panel i designed
08:57 PM roycroft: this is why i wanted to wait until it arrived before building my control panel
08:57 PM Tom_L: cut a hole in the side of it and weld some more cabinet to it
08:58 PM Tom_L: if i ever get one, i'll mount it to the side
08:58 PM Tom_L: my pannel isn't big enough
08:59 PM roycroft: waiting until the part arrived before building its housing works fine :)
08:59 PM roycroft: so when is your mill going to be done?
08:59 PM roycroft: you've made a lot of progress on it
08:59 PM Tom_L: that's the mystery question
08:59 PM roycroft: the answer is actually very simple:
08:59 PM Tom_L: i got my belt today so i decided to make a guard for it
08:59 PM roycroft: it will be done when it is done
09:00 PM Tom_L: i had a belt but had to change where the motor mounted
09:00 PM Tom_L: so i needed a longer one
09:00 PM roycroft: i know for growing projects
09:00 PM Tom_L: but i'm not in a hurry
09:01 PM Tom_L: the cover would have been nicer probably if i had a spot welder
09:01 PM roycroft: i am kind of anxious to get this current project completed, because i have two others on its heels
09:01 PM Tom_L: instead i just wrapped a strip around the perimeter and mig welded it
09:01 PM roycroft: i got one from hf a few years ago marked way down at one of their tent sales
09:01 PM roycroft: i figured that it was a fairly safe thing to get there - it's just a transformer, a cord, a switch, and some copper rods
09:02 PM roycroft: it was missing the slide hammer so it was almost free - i think i paid \$30 for it
09:02 PM Tom_L: i hadn't used my mig that much and was having issues with it. once i got them ironed out i think i'm liking it alot
09:02 PM Tom_L: learned on stick
09:02 PM roycroft: i rang up their customer service folks, wanting to know how much the slide hammer was (the ones for pulling body studs are different from the ones i have)
09:02 PM Tom_L: ahh
09:02 PM roycroft: and they told me it should have been included with the spot welder, so they sent it to me gratis
09:03 PM roycroft: i don't use the spot welder often, but when i need it it works better than anything else i can imagine
09:03 PM Tom_L: the mig worked great actually
09:04 PM roycroft: yeah, those can work well
09:04 PM Tom_L: just turned it way down
09:04 PM roycroft: a lot easier than stick welders at low amperage
09:04 PM roycroft: on my list for this spring is to get good at tig welding
09:04 PM roycroft: i've had a tig welder for about 6 or 7 years, and i hardly ever use it
09:04 PM Tom_L: tig would be nice but i doubt i'd use one that much
09:05 PM roycroft: if i ever get decent at it (which shouldn't take very long) i'll probably use it for most of my welding
09:05 PM roycroft: i don't weld that often, and i always spend 2x as much time grinding than welding
09:05 PM roycroft: if i get good with the tig welder i should be able to eliminate most of the grinding
09:05 PM Tom_L: i'm getting better at it
09:06 PM roycroft: that's the theory anyway
09:06 PM roycroft: and the hope
09:06 PM * roycroft thinks it's time to make dinner
09:21 PM dioz: yo
09:21 PM dioz: i have a question for you guys

09:22 PM dioz: in stead of the threads being perpendiular to the handle

09:22 PM dioz: i just can't seem to find a resaonable name to find an image even
09:23 PM dioz: like that sort of
09:24 PM dioz: like the wrench he uses in this video
