#linuxcnc Calendar

12:00 AM XXCoder: wonder why they didnt
12:03 AM CaptHindsight: but they only post binary GPU accel for Mali built for one version kernel
12:03 AM Cromaglious__: no worky http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RaspberryPi
12:03 AM CaptHindsight: they don't want Mali source released
12:03 AM CaptHindsight: Cromaglious__: that page is ancient
12:03 AM CaptHindsight: check the mail list, Gene had trouble building but it all works
12:03 AM CaptHindsight: https://sourceforge.net/p/emc/mailman/message/35651672/
12:03 AM CaptHindsight: went on for several weeks
12:05 AM CaptHindsight: XXCoder: what hours do you work? is this early or later for you?
12:05 AM XXCoder: I work 3:15 pm to 1:45 am
12:05 AM XXCoder: so its... middle really. 10 pm heh
12:05 AM CaptHindsight: similar to my work hours
12:06 AM CaptHindsight: I'm writing emails to people in the EU right now
12:07 AM CaptHindsight: same with China, I'll write them and they will wait until my mid day to write back when I'm up now
12:08 AM XXCoder: fun living in sphere world eh heh
12:09 AM CaptHindsight: sometimes I wish we had 30 hour days
12:09 AM XXCoder: that'd mean more work
12:09 AM XXCoder: and we'd wish for 35 hours. where does it end??
12:10 AM CaptHindsight: this time of year sun up or down doesn't matter much
12:11 AM CaptHindsight: to me anyway
12:11 AM XXCoder: only difference is what time outside goes dark :)
12:11 AM XXCoder: my poor bro, in winter he goes to work in dark, and returns to work in dark
12:48 AM roycroft: it is light when i get home from work now, and twilight when i leave for work (as opposed to totally dark as it was just a week ago)
12:49 AM XXCoder: night shifts is fun heh
12:50 AM roycroft: this is as far north as i want to live, although i did live right next to the canadian border for 15 years
12:50 AM XXCoder: easy enough to dig nder and escape into canada ;)
12:51 AM roycroft: i lived in bellingham before i moved to eugene
12:51 AM roycroft: i really liked it there
12:52 AM roycroft: except the winters
12:52 AM XXCoder: lots ice and snow?
12:52 AM roycroft: it got pretty cold at times
12:52 AM roycroft: and yes, we got snow that did not go away the next day like it's supposed to
12:52 AM roycroft: the year the city of bellingham sold its only snow plow i decided it was time to move
12:53 AM roycroft: the previous year we had a heavy snow that did not melt for two weeks
12:53 AM roycroft: that whole time i had to park two blocks away from my house because the hill was too steep for cars to drive with the ice
12:53 AM roycroft: and it was pretty hard walking up the hill that whole time
12:54 AM XXCoder: heh reminds me of old home I lived at
12:54 AM XXCoder: I had to walk up hill in order to get on bus to go to school
12:54 AM roycroft: bellingham is right on the strait of juan da fuca
12:54 AM roycroft: and has a maritime climate
12:55 AM roycroft: but we got noreasters in the winter that came down from the far north down the fraser river valley that brought nasty cold weather
12:56 AM roycroft: we had much colder weather than either seattle or vancouver
12:56 AM XXCoder: yeah west wa has nmoderate winters
12:56 AM XXCoder: rarely snow, let alone multi-day snows
01:03 AM roycroft: the snow also doesn't stay around often
01:03 AM roycroft: it only snows when it's right around freezing
01:04 AM roycroft: because it never gets much below freezing unless the sky is clear - if there are clouds it is never cold
01:04 AM roycroft: the problem in bellingham is that we would often get snow and then a nor'easter would blow in
01:05 AM roycroft: clear out the clouds, and it would get cold for a few days
01:06 AM XXCoder: fun heh
01:10 AM roycroft: sunset will be at 5:00 tomorrow
01:10 AM roycroft: nice
01:13 AM XXCoder: earth should be around closest to sun at this point
01:13 AM IchGucksLive: morning from germany
01:14 AM jesseg: Good morning to Germany
01:14 AM jesseg: because it sure as anything isn't morning here :D
01:14 AM XXCoder: good pre-morning from usa
01:14 AM jesseg: that's the spirit XXCoder
01:14 AM IchGucksLive: he never sleeps so it seems
01:15 AM XXCoder: probably because i am literal spirit also ;)
01:15 AM IchGucksLive: the best spirit is the President DT
01:16 AM IchGucksLive: on suturday he hit the Rate OB had after 8years as in 270 days on personal spending
01:16 AM IchGucksLive: thats cool or say coal
01:17 AM IchGucksLive: the saturdays golfcort dinner has made the tax payer 32million
01:17 AM IchGucksLive: Best president ever realy mean this
01:48 AM IchGucksLive: in out day this morning
02:10 AM Deejay: moin
02:10 AM Contract_Pilot: Evening
02:40 AM * gloops wonders how hard stepper motor shafts are
02:42 AM archivist: sufficiently hard
02:44 AM gloops: thinking of trying to drill to bolt pulley on
02:45 AM XXCoder: very hard I'd say? stainless steel?
02:45 AM XXCoder: I wanted to add flats to my steppers but its bit hard to do
02:45 AM gloops: ally pulleys - only small taps ive got are fine thread, useless for tightening with grub screws
02:45 AM CaptHindsight: archivist: where did England get its gas from for lighting during the 1800's? Coal derived or?
02:46 AM archivist: from coal
02:46 AM gloops: bolted pulleys straight through ballscrews, think motors are harder
02:46 AM archivist: coal gas lasted till the 1960's
02:46 AM IchGucksLive: im off
02:47 AM archivist: then the first town to be converted to natural gas was right here in Burton upon Trent
02:48 AM XXCoder: with power, arc lights
02:48 AM gloops: and drill bit smaller
02:48 AM CaptHindsight: archivist: was it also used to power machinery back then?
02:48 AM archivist: not really no
02:48 AM gloops: theyre taking coal gas out of a closed coal mine near me - Hargreaves, still in use, apparently making more from the gas than the coal
02:49 AM CaptHindsight: coal fired steam boilers back then?
02:50 AM CaptHindsight: boilers and engines to power a factory?
02:50 AM archivist: coal fired steam also lasted into the 60's for industry as well as generation
02:50 AM archivist: later on steam would be process steam though
02:51 AM gloops: lots of chimneys, big ones 200ft high
02:51 AM CaptHindsight: ok, was mainly looking at the Victorian era
02:52 AM gloops: http://www.thepotteries.org/photos_set/hanley_1930_times.jpg
02:52 AM CaptHindsight: interesting, thanks
02:53 AM gloops: http://c7.alamy.com/comp/KHB5EK/the-black-country-19th-century-view-of-oldbury-west-midlands-industrial-KHB5EK.jpg
02:53 AM archivist: one of the local pits was lifted by steam till very late 1990 ish
02:55 AM archivist: went to a salt mine where the produce lots of process steam to dry the brine, they also want power and low pressure steam so they use steam engines still
02:55 AM gloops: http://old-rotherham.esy.es/Images/BFA007.jpg this is where i live - all gone now
02:56 AM gloops: in the war the luftwaffe were constantly trying to bomb it, but never got a good hit, apparently they followed a train going to the works one night, the driver heard the planes and pulled up in a tunnel, foiling the attack
02:56 AM CaptHindsight: hah
02:58 AM archivist: https://commons.wikimedia.org/wiki/File:Belliss_and_Morcom_engine_at_New_Cheshire_Salt_Works_Ltd_-_geograph.org.uk_-_638861.jpg
02:58 AM archivist: removed 2006
02:58 AM gloops: with the rotherham steelworks you had 3 elements - all had a coal mine next door, literally next door, and water - a river
02:58 AM archivist: I was with that photographer :)
02:59 AM CaptHindsight: bedtime for Bonzo, bbl
03:00 AM gloops: https://cdn.liveleak.com/80281E/s/s/19/media19/2012/Mar/24/LiveLeak-dot-com-9509dacae1c5-parkgate_iron_and_steel_co_rotherham_1901.mp4.h264_base.mp4?zFoeqW8QbvCPhTBeWgz34l-aOF0yXhDr5Y3BbCN-ka1WLWBwOYC2Gmf6OyjjPen-&ec_rate=250
03:00 AM gloops: at the factory gates, a number of those reels were found in a deserted photographers shop
03:02 AM archivist: I found slides at Lucas, saved them :)
03:03 AM Contract_Pilot: Prob going to seen how fast i can electrucute my self.
03:03 AM Contract_Pilot: or burn up my vfd or bob hahaha
03:03 AM gloops: only building they preserved was part of guest and chrimes in rotherham, guest and chrimes basically invented the bathroom tap and many other brass valves, went in the 70s i think
03:07 AM archivist: I have a catalogue http://www.collection.archivist.info/searchv13.php?searchstr=ct+guest
03:07 AM gloops: not finding the pics archivist
03:08 AM archivist: because scanning paper is hard
03:08 AM archivist: I catalogue stuff then scan if I get nagged/asked
03:09 AM gloops: they made a monument from the steel peach and tozer works - a steel circle like stonehenge made from large billets, only been a month and the scrap men had 2 lumps
03:11 AM archivist: scrap men are getting a bit brazen, mate had something stolen a week ago
03:11 AM gloops: http://www.wildlifetrusts.org/sites/default/files/imagecache/page_image_large/main-photos/centenary_riverside_may_2013_cpt_sarah_sidgwick_6_0.jpg
03:11 AM XXCoder: I wonder if you could fake scrap metal archivist
03:12 AM XXCoder: rocks that look like metal, and are very heavy
03:12 AM gloops: missing plinths
03:31 AM Contract_Pilot: I may not take any drugs in the morning and see how it goes
03:31 AM Contract_Pilot: Prob regret it.
04:36 AM jthornton: morning
06:17 AM Tom_L: 34F and snow
06:18 AM jthornton: 26°F and overcast with snow 70% later in the day
06:24 AM Deejay: Toms encoding is not utf8 :(
06:53 AM gloops: https://www.ebay.co.uk/itm/DC-36V-1-6A-1-8A-Amp-CARICABATTERIA-AC-220V-BATTERIA-DIN-3-PER-BICI-ELETTRICA/322734386538?
06:53 AM gloops: why wont that run a stepper motor?
06:55 AM XXCoder: that looks like just power source? dunno
06:55 AM XXCoder: doesnt look like driver
06:55 AM gloops: well yeah through the driver
06:56 AM archivist: gloops, http://www.collection.archivist.info/archive/catalogues/CT169_Guest_and_Chrimes/page_0002.jpg
06:56 AM gloops: i dont know much about electrics, but 36v, 1.8amp , within a steppers limits
06:58 AM archivist: that is a charger not a power supply
06:58 AM gloops: ahh yes interesting archivist, ive seen various documents posted in rotherham facebook group, and some history and people who worked there, forget most of it now
06:58 AM gloops: giving out the same volts/amps though?
06:59 AM Wolf__: if its a dumb charger it is just a cheap 36v power supply
06:59 AM archivist: it is an A4 full book style catalogue
06:59 AM archivist: the text show litheum voltages not 36v
06:59 AM Wolf__: but I would go with a actual power supply
06:59 AM gloops: you see guest and chrimes manhole covers everywhere, for the stop taps in the street, all those kind of things
07:00 AM archivist: catalogue is very much commercial waterworks fittings
07:00 AM gloops: Wolf yeah i will buy a proper one, just wondered, if you got 1 of the chargers for each stepper you arent saving much anyway
07:01 AM Wolf__: plus fire hazard
07:01 AM gloops: a lot of women worked there as polishers i think, the remaining bit of building looks like that long thin section in the middle
07:01 AM gloops: steel in rotherham was started by the Walker family
07:02 AM gloops: http://s0.geograph.org.uk/geophotos/01/43/62/1436242_5d5b3289.jpg
07:03 AM archivist: I have another manhole casting company catalogue somewhere
07:05 AM gloops: the entire place was just black filthy steelworks and engineering shops, probably 5 square miles
07:06 AM XXCoder: https://www.youtube.com/watch?v=IBdLRw34DqM& interesting
07:06 AM XXCoder: im not sure why guy split the "fins"
07:06 AM gloops: can remember at least 3 roads that ran straight the pit yard, coal much piled up a foot deep both sides heh, kids playing in it
07:08 AM archivist: gloops, some funny shapes in london http://www.collection.archivist.info/archive/catalogues/CT1027/page0001.jpg
07:11 AM gloops: the triangular ones are pretty common round here, not seen the jigsaw piece one before
07:12 AM gloops: ill have a look through the rotherham page later see if i can find any interesting photos or docs, there were loads posted when it first started, now mainly pics of flowers and sunsets
07:16 AM archivist: scanner did not like the weight of the catalogue this morning, it jammed
07:19 AM gloops: https://postimg.org/image/8wovcr58j/ job coming out of robert jenkins
07:19 AM XXCoder: man that must be real hefty cat
07:19 AM gloops: ever used a bike to go up and down you lathe heh
07:20 AM gloops: "de-ethaniser column" on its way by road to Sheffield to be taken by rail to "British Hydrocarbon Chemicals" at Grangemouth
07:25 AM gloops: https://postimg.org/image/bfakdn90z/ similar layout to guest and chrimes, peter stubbs works, think these were crucible furnaces founded by the walkers
07:31 AM gloops: rolling mills https://postimg.org/image/ldvizu837/
07:31 AM gloops: had an uncle who was a roller there, everything got sold to the japanese lock stock and barrel
07:34 AM archivist: stubbs was a loss with their files and silver steel
07:34 AM archivist: how did they take the pictures without drones!
07:35 AM XXCoder: tower or helicoper
07:35 AM gloops: aeroplane/balloon?
07:35 AM XXCoder: or plane if picture taing is fast enough
07:35 AM XXCoder: ah ballon yeah that too
07:36 AM archivist: many like the stubbs image are just artists impression :)
07:36 AM XXCoder: after they yake ballon ride? ;)
07:37 AM gloops: they would have been something back in the day, a factory like that, state of the art, hitherto unknown
07:38 AM gloops: steam tractors doing all the work in the fields, the lads all had to clock on at the foundry
07:38 AM gloops: or mill, or bleach works
07:40 AM archivist: we get a regular questions at Leawood of how the engine got there and how it was assembled, in 1849
07:41 AM gloops: slowly?
07:41 AM archivist: we know there was canal all the way from Barnsley :)
07:42 AM archivist: and the beam is not far off the canal level
07:42 AM gloops: yeah boat, or rail maybe
07:43 AM gloops: well, wasted an hours building time
09:15 AM IchGucksLive: hi
09:52 AM MrHindsight: rare to see catastrophic failure of architecture http://www.wsj.com/video/balcony-at-indonesia-stock-exchange-collapses-scores-injured/EEB8ADB0-EF9E-4505-AFF1-40D6095082E1.html
09:58 AM ziper: why is this little thing bidding so high https://www.bidspotter.com/en-us/auction-catalogues/bsccl/catalogue-id-bsccl10043/lot-41e8b1c4-a61f-44eb-b2a6-a855013f5ea0
09:59 AM ziper: what was the one where they had the hanging walkway and they bolted it up wrong or something?
10:00 AM gregcnc_: 550 isn't high for those hardinge 2nd op lathes
10:00 AM gregcnc_: maybe at auction
10:00 AM Wolf__: auction bids are funny things
10:00 AM Wolf__: one next to it is half the price lol
10:01 AM gregcnc_: that one has the cutoff slide and some kind of compiund slide
10:01 AM MrHindsight: there was one or two on the local CL that were >$1k for months
10:01 AM gregcnc_: quite possible someone has inspected in person
10:02 AM Wolf__: ^ or that
10:03 AM gregcnc_: https://www.ebay.com/itm/173007990563
10:03 AM Wolf__: but I have seen people fight over one item when there is 4 others at the same auction
10:04 AM gregcnc_: those have value, i guess they are still useful
10:04 AM MrHindsight: https://chicago.craigslist.org/nch/tls/d/hardinge-59-lathe-bed-ways-in/6443333752.html
10:04 AM Wolf__: I could see the usefulness of those lathes for 2nd op or making tons of the same thing
10:04 AM MrHindsight: for just the way
10:06 AM MrHindsight: https://chicago.craigslist.org/nwc/hvo/d/large-leblond-19e7-lathe-for/6454679252.html
10:26 AM gloops: https://www.ebay.com/itm/LeBlond-12-x-105-3-Phase-440-Volt-AC-Lathe-in-Mississippi-NO-RESERVE/282808388651?
10:45 AM Tom_L: 19F was 34 earlier
10:52 AM IchGucksLive: Rain puring down here and storm in forcast
10:54 AM roycroft: we have pea soup fog still, with rain coming in later on today
10:55 AM roycroft: the fog is so thick there is virtually zero visibility, so of course all the people in silver and white pickups (mostly) and cars were driving without their lights on this morning
10:55 AM * roycroft will be happy when drl are mandatory here
11:19 AM fragalot: >.> mesa board arrived.. forgot it at work.
11:20 AM JT-Shop: I hate when that happens
11:21 AM Tom_L: JT-Shop, gettin any snow yet?
11:22 AM JT-Shop: just started a few minutes ago
11:23 AM Tom_L: we got just enough to pay the body shop's rent for a couple months
11:23 AM JT-Shop: lol
11:29 AM gloops: when does contruction begin fragalot?
11:32 AM fragalot: gloops: once I narrow down what kind of design I want & order the parts for that
11:32 AM fragalot: There's no real rush :-)
11:32 AM fragalot: need paychecks to come in in between, lol
11:37 AM gloops: saw a good design with a bridge today on facebook
11:38 AM IchGucksLive: hi ;_)
11:38 AM fragalot: gloops: care to share?
11:38 AM fragalot: hi IchGucksLive
11:38 AM gloops: https://postimg.org/image/3s1g0pz4j/
11:38 AM gloops: its a router though i think
11:38 AM IchGucksLive: fragalot: have you asked about 60V generator small cabinett ß
11:39 AM fragalot: IchGucksLive: who what where when ?
11:39 AM gloops: thats a fine machine
11:39 AM fragalot: I already have the power supplies
11:39 AM fragalot: gloops: that does indeed look pretty neat
11:39 AM IchGucksLive: to save space
11:39 AM gloops: hes put some time into that
11:40 AM fragalot: the issue with welding up a frame I have is that I don't know where I can get it heat treated
11:40 AM fragalot: and i'm worried the stresses will catch up with me later
11:40 AM gloops: yeah that is a bit of a drawback with steel
11:40 AM IchGucksLive: the problem on this stiff setup is the mauell toolchange
11:40 AM fragalot: I don't mind manual toolchanges
11:40 AM IchGucksLive: i woudt have given it a Y offset
11:41 AM fragalot: the spindle I got doesn't allow an ATC anyway
11:41 AM IchGucksLive: best to dont run in problems
11:41 AM gloops: yeah hes got the Y nut set to the right
11:41 AM fragalot: IchGucksLive: perhaps his spindle sticks out far enough that it has one?
11:41 AM gloops: why didnt he move the screw over? so he can access the nut i guess
11:42 AM gloops: without stripping the z
11:42 AM fragalot: gloops: he can get away with a shorter leadscrew
11:42 AM IchGucksLive: Somtimes people build mashinesfor one part
11:43 AM gloops: fragalot i wouldnt have thought he was bothered about 6 inch of screw price
11:44 AM fragalot: gloops: shorter screws are more rigid too
11:44 AM fragalot: and if you offset the nut to be able to access it anyway... everyone wins?
11:44 AM gloops: its a bit ott for wood, should be good for ally though, also z looks very long travel
11:46 AM gloops: fragalot i suppose yeah
11:46 AM IchGucksLive: gloops: stiff for light steel
11:46 AM gloops: Ichs maybe thats what he has in mind yeah
11:47 AM IchGucksLive: its like fragalot build the mashine where it is and no way out
11:47 AM IchGucksLive: on that price i woudt go for a maho700
11:48 AM IchGucksLive: or if Room as not exists BT15 alzmetall around 2500 used
11:48 AM gloops: the bloke says he moved the bits from his chinese router, the steel was free
11:48 AM IchGucksLive: like tooltime
11:48 AM IchGucksLive: more power
11:48 AM fragalot: there would be a way out for my machine
11:49 AM fragalot: all I need to do is remove a wall
11:49 AM fragalot: and rent an offroad forklift
11:49 AM IchGucksLive: military P6
11:53 AM Wolf__: my poor credit card…
11:53 AM fragalot: Wolf__: that's why I don't have one!
11:54 AM Wolf__: lol
11:54 AM fragalot: (that, and I couldn't get my house loan approved as long as i had an open CC account)
11:54 AM Wolf__: if I was smarter I wouldnt have one either lol
11:54 AM fragalot: regardless of if there was any debt outstanding
11:54 AM Wolf__: odd
11:55 AM Wolf__: about to hit order on a new GPV-615 vise
11:55 AM fragalot: isn't that one a rebrand of another vice?
11:56 AM Wolf__: I dont think so
11:58 AM fragalot: I think I heard they are basically a painted Shars vice
11:58 AM fragalot: or at the very least the same casting with a new paintjob over the old one.. no idea if they regrind them
12:02 PM Wolf__: hmm, does look similar
12:04 PM fragalot: well they are both kurt clones, so looks aren't everything :P
12:04 PM Wolf__: yeah that I do know lol
12:05 PM IchGucksLive: BonJour gibi92
12:06 PM Wolf__: GPV-615 is $599 shipped right now, shars is $478 shipped
12:07 PM Rab: I've heard that Glacern chucks are very well regarded.
12:07 PM fragalot: (note that I'm making no claims that GMT is "bad")
12:08 PM fragalot: like I said, for all I know the castings are identical, but GMT puts more effort into the grind / finish
12:08 PM Wolf__: yeah, just makes me wonder if GMT is $120 better
12:09 PM fragalot: don't know
12:09 PM fragalot: can you get a known-to-be-good discounted kurt for a similar price?
12:09 PM fragalot: or an orange?
12:10 PM fragalot: never mind, I just looked up what orange vises cost, haha
12:10 PM Wolf__: yeah lmao
12:10 PM IchGucksLive: BOSCH
12:10 PM fragalot: do bosch make workholding tools?
12:11 PM IchGucksLive: they do alot
12:11 PM Wolf__: yeah, but usa market?
12:12 PM fragalot: https://www.amazon.co.uk/Bosch-2608030055-Machine-Tool-Vice/dp/B0014169XQ
12:12 PM fragalot: that 'l work fine, Wolf__
12:12 PM Wolf__: kurt 3600V is $835 on the kurt site
12:13 PM fragalot: Wolf__: what about enco?
12:13 PM fragalot: they often seem to do great deals on kurt vices for you USA lads
12:13 PM Wolf__: enco is gone
12:13 PM fragalot: oh.
12:13 PM Wolf__: MSC ate them a couple years ago
12:14 PM IchGucksLive: fragalot: https://www.paulimot.de/schraubstoecke/
12:14 PM IchGucksLive: ofcause homedepo got also stuff
12:14 PM fragalot: I see nothing good there
12:15 PM fragalot: the grinding vices are usually almost always really good, even the imports
12:15 PM fragalot: but that style of milling vices that paulimot sells sucks
12:15 PM IchGucksLive: toolstream
12:16 PM Rab: Like this? Looks more like a nice drill press vise to me. https://www.paulimot.de/schraubstoecke/bohrmaschinen-schraubstoecke/438/bohrmaschinen-schraubstock-100-mm-backenbreite
12:17 PM fragalot: moving jaw is too short to be a nice drill press vise
12:18 PM fragalot: I mainly use Vertex vices here (Taiwanese; good enough for me)
12:19 PM fragalot: no idea if they'll keep their accuracy as the castings age
12:19 PM fragalot: and the finishing (burrs) is.. well there is none on the bottom of the casting, lol
12:22 PM Wolf__: nothing on MSC is catching my eye, only thing similar is the kurt 3600V, no asian clone there
12:25 PM Wolf__: GMT it is…
12:25 PM fragalot: yup, lol
12:26 PM roycroft: msc keep bugging me to buy from them
12:26 PM fragalot: $120 gets you an american to bug if something's not right
12:26 PM roycroft: when they shut down enco they told me they would grandfather enco pricing for things i've purchased within the past year for a year
12:26 PM roycroft: but i would have to pay msc pricing for everything else
12:26 PM roycroft: mcs pricing is roughly 30% higher than enco pricing for the exact same items
12:27 PM roycroft: well, *my* mcs pricing is that much higher
12:27 PM Wolf__: yeah, I haven’t even set up a MSC account
12:27 PM roycroft: i know they give good discounts to large shops
12:27 PM roycroft: but they basically screwed all the enco people
12:29 PM roycroft: it's too bad
12:29 PM roycroft: i use a half dozen or so suppliers now
12:29 PM roycroft: i used to get almost all my machining tooling/supplies from enco
12:29 PM Wolf__: I do need to order some taps and other stuff, need to figure out where to order from
12:29 PM roycroft: now i have to waste a bunch of time going all over the place
12:29 PM Wolf__: now…
12:30 PM roycroft: i get giving discounts for large orders - the processing cost is amortized out that way
12:30 PM roycroft: but to just jack the prices up because of small volume is not right
12:31 PM Wolf__: yeah =/
12:31 PM roycroft: especially for a company who do web-based orders that do not require sales people or any of that kind of support infrastructure
12:31 PM roycroft: adding a handling cost for small orders can be ok, if it's reasonable
12:31 PM roycroft: someone has to stick the thing in the box
12:31 PM roycroft: and you pay that person the same amount of money to stick a $10 part in a box as a $300 part
12:32 PM roycroft: but to charge significanly more across the board, regardles s of order size, is just jerking people around because they think they can get away with it
12:32 PM fragalot: or if you keep the margin low enough to warrant a difference in handling cost
12:34 PM roycroft: victor machinery have good prices on taps and dies, wolf__
12:34 PM roycroft: they're in brooklyn
12:34 PM roycroft: i've used them several times
12:35 PM Wolf__: cool
12:37 PM fragalot: I've finally found a pro quality tool manufacturer that ships to nobodies like me as well
12:38 PM fragalot: no more 2nd hand regrinds or chinesiums for me! :-)
12:38 PM Wolf__: cutters I have been ordering from maritool
12:39 PM fragalot: not economical at all for me to order from them
12:39 PM fragalot: import duties are too much
12:40 PM Wolf__: yeah true
12:40 PM fragalot: wish I could though, their prices are alright
12:40 PM fragalot: and they have a pretty broad range
12:41 PM Wolf__: but for now I’m covered petty well with the shop I bought
12:41 PM Wolf__: https://i.imgur.com/jdLAqLp.jpg
12:42 PM fragalot: christmas time?
12:42 PM roycroft: victor machinery carry domstic and imported tooling
12:44 PM Wolf__: fragalot: pretty much lol
12:44 PM fragalot: bit extreme though to have to buy a whole shop just to get the tools :P
12:45 PM Wolf__: well I wanted the mill and lathe https://i.imgur.com/0r177E3.jpg https://i.imgur.com/YRBzo24.jpg
12:45 PM fragalot: ah yes that makes sense.
12:46 PM Wolf__: about of tooling was a big plus
12:46 PM Wolf__: amount*
12:46 PM fragalot: that's about the perfect size of lathe for my shop
12:46 PM fragalot: :P
12:46 PM Wolf__: 12x37
12:47 PM fragalot: the only thing I don't like about the lathe i've got now is that there's no gearbox for threading
12:47 PM fragalot: need to change the gear sets manually which takes forever
12:47 PM Wolf__: this one was missing the change gears and lead screw
12:47 PM fragalot: I've often wondered if i could mount an encoder on the spindle & put a stepper on the leadscrew, lol
12:48 PM Wolf__: yeah you could do that
12:48 PM Wolf__: thats what most of the channel was saying I should have done to fix the missing lead screw lol cnc it
12:49 PM fragalot: xD
12:49 PM fragalot: I don't want to CNC the whole thing
12:49 PM fragalot: just put up a little character display where I can enter the desired pitch
12:49 PM Wolf__: arduino drive it lol
12:50 PM fragalot: exactly
12:51 PM Wolf__: add a end switch to that and would have crash proof threading
12:51 PM Wolf__: I got lucky and got a new lead screw from someone here doing a cnc conversion https://i.imgur.com/dbbG2m4.jpg
12:52 PM fragalot: I have crash proof threading because of the plastic taper pin in the leadscrew, lol
12:53 PM Wolf__: mine should be crash proof due to plastic gears
12:53 PM Wolf__: https://i.imgur.com/d6eqnNG.jpg =)
12:54 PM fragalot: haha
12:54 PM fragalot: I have to say I never considered printing them
12:54 PM fragalot: (even if i have already worn out 3 3D printers)
12:54 PM Wolf__: I printed some for my 7x10 POS lathe
12:56 PM Wolf__: I should be on the machines right now finishing the DRO install and thread dial
12:56 PM roycroft: is there such a thing as dom square tubing that is reasonably thick?
12:56 PM roycroft: as on 0.25" or 0.375" in smallish cross section
12:56 PM fragalot: thread dials are the only thing I like about imperial lathes
12:57 PM roycroft: i'm looking for 1.5" inside measurement and 0.25" or 0.375" wall thickness, so 2" or 2.25" outside
12:57 PM roycroft: i can only find the really thin stuff (0.120" or 0.085")
12:57 PM Wolf__: yeah, that should be easy to find
12:58 PM roycroft: dom i'm talking about
12:58 PM roycroft: or some other seamless kind
12:58 PM roycroft: so that it can telescope
12:58 PM gloops: just designed a massively ingenious clamping system for wooden circles
12:58 PM gloops: which i wont be sharing atm
12:58 PM Wolf__: yeah, at worst call a trailer shop and see if they will sell you some hitch DOM
12:58 PM fragalot: lol
12:59 PM fragalot: gloops: does it involve stacking them & sitting on top?
12:59 PM roycroft: yeah, i'll check with my local metal supplier tomorrow
12:59 PM roycroft: they do hitch stuff
12:59 PM gloops: nope, its cable clamp system
12:59 PM Wolf__: I know I have 2” inside DOM 0.25” wall
01:02 PM Wolf__: you could also just use seamed tube but put a clearance slot on the siding tube
01:03 PM nallar is now known as Ross
01:06 PM fragalot: make a giant broach to clean up the weld seam from the inside
01:07 PM Wolf__: that thought crossed my mind as well
01:07 PM roycroft: it appears that hitches come in 1.25" and 2"
01:07 PM roycroft: not 1.5" which is what i want
01:07 PM roycroft: so hitch receiver tubing would not work
01:07 PM roycroft: i'll still check with my metal supplier tomorrow to see what they have to say
01:08 PM roycroft: filing, broaching the weld line is also an option, but a very not fun option
01:08 PM gloops: first cut of that butch router https://www.youtube.com/watch?v=qkReb2ik_-o&feature=youtu.be
01:08 PM gloops: 5m/min, he could go a hell of a lot faster and deeper
01:09 PM fragalot: roycroft: the .25" clearance is to provide space for the turcite to scrape the sliding surfaces in
01:10 PM fragalot: gloops: can the kress spindle take larger side loads?
01:10 PM roycroft: i think 0.010" clearance is more within my tolerence tolereance :)
01:11 PM roycroft: 25x that much is a bit on the sloppy side
01:11 PM Wolf__: roycroft: tubing for that belt grinder?
01:11 PM roycroft: yes
01:11 PM roycroft: i have zero interest in welding up four pieces of flat stock
01:12 PM Wolf__: for that I would just mill a slot in to the telescope tube stock
01:12 PM roycroft: it would be faster and easier to file the weld line off some hot roll tubing
01:12 PM roycroft: i've done that in the past
01:12 PM roycroft: it's inelegant, at the very least
01:12 PM roycroft: for that application, with only two short receiver tubes, i'd file the weld lines off
01:13 PM Wolf__: yup, put it on the bottom =P
01:13 PM roycroft: what is the bottom?
01:13 PM roycroft: the thing pivots
01:13 PM Wolf__: oh right
01:13 PM fragalot: angle it 45°
01:14 PM fragalot: more seriously; it's a grinder, which may or may not get painted, and will get coated in grinding dust
01:14 PM fragalot: you won't be able to tell
01:15 PM Wolf__: either way it will look better then a giant pile of 1/2 bar stock welded together lol
01:38 PM JT-Shop: yogurt break is over with back to grinding and welding... my least favorite task
01:38 PM fragalot: I too do not like yoghurt breaks
01:41 PM HighInBC: indeed
01:48 PM miss0r: snow is starting to come down somewhat hard here
01:49 PM miss0r: and by danish standard, that is a light drizzle :)
01:53 PM fragalot: :)
01:57 PM miss0r: lol. I placed an order with RS components. one package will be sent from GB, one from DE & one from here in DK. The packages from DE & GB will arrive tomorrow, the one sent within DK will arrive thursday... Thank you danish postal services...
01:58 PM fragalot: the best part?
01:58 PM fragalot: the other packages will be subcontracted to the danish postal service for the final delivery
01:59 PM Wolf__: sounds like the air cylinder i’m waiting on here...
01:59 PM miss0r: all but the one from GB, that will be sent with DHL
01:59 PM Wolf__: ordered a air cylinder from ebay, its been taking a tour of the USA via postal service, ordered a DRO from china and it was here in 8 days
01:59 PM miss0r: damn
02:00 PM roycroft: my vfd remote panel that i ordered in november from china still is not here :(
02:00 PM roycroft: the one i ordered last week to replace it is due to arrive tomorrow
02:00 PM roycroft: but i paid a premium for shipping on that
02:00 PM miss0r: ... we shall see
02:01 PM Wolf__: the air cylinder shipped on 12/30/17
02:01 PM miss0r: Anyway, I just got in here to turn off the computer and have a smoke. See you around
02:07 PM Wolf__: damn I think my vise might ship same day
02:13 PM roycroft: you'll live a longer life without vices, wolf__
02:13 PM Wolf__: yeah, but what fun would that be
02:15 PM roycroft: fun is overrated
02:18 PM gloops: another oldie from rotherham, rolling mill https://postimg.org/image/fsw2snaxf/
02:20 PM roycroft: i need a rolling mill
02:20 PM roycroft: i wish they were not so expensive
02:20 PM roycroft: but i guess they need to be if they are to work
02:21 PM gloops: https://postimg.org/image/a4ps1ywcz/
02:21 PM gloops: you can get a hand roller, depends what you want to roll i suppose
02:23 PM roycroft: metal
02:23 PM roycroft: wire, specifically
02:23 PM roycroft: those sub-$200 ones on ebay are shite
02:24 PM Wolf__: I need a big ass brake (probably press type)
02:24 PM roycroft: http://www.ottofrei.com/Durston-C80-Combination-Mini-Rolling-Mill
02:25 PM roycroft: that's probably the least expensive one that will do a decent job
02:25 PM roycroft: i just need to take copper, brass, and precious metal wire and make it flat to use for inlay
02:25 PM Wolf__: I know someone that has a rolling mill…
02:26 PM Wolf__: its a bit bigger then that thing
02:26 PM gloops: yeah that type of thing roy, there are older cast iron versions, someone had one on his back yard to roll gold with for jewellery
02:26 PM roycroft: would this person sell it cheap? :)
02:27 PM roycroft: durston make good roller mills
02:27 PM Wolf__: doubt it, the one I have in mind is probably 5000lbs
02:27 PM gloops: years ago when i saw it heh
02:27 PM roycroft: british goods are generally better than chinese goods
02:28 PM gloops: a bit of bar https://postimg.org/image/uq4jtm65f/
02:29 PM gregcnc_: is that your back or front yard?
02:29 PM Wolf__: roycroft: https://youtu.be/R0mLevcWMxw
02:30 PM gloops: gregcnc i cant afford a posh house like those
02:30 PM roycroft: i'd actually like to try one of the sub-$200 ebay ones
02:30 PM roycroft: everyone says they are shite, but it might work just to flatten wire
02:31 PM roycroft: if the gears are cast and not machined i would probably not be too happy with it
02:32 PM gloops: only posting these because Capthindsight was asking if the UK used coal in industry lol https://postimg.org/image/a5zpvet1v/
02:32 PM gloops: 2nd bloke looks knackered
02:35 PM MrHindsight: gloops: coal gas not coal :)
02:35 PM fragalot: I have a rolling mill
02:35 PM JT-Shop: I wonder if you can cut AR400 with a bandsaw?
02:35 PM MrHindsight: gloops: i thought you guys even ate and drank coal :)
02:36 PM fragalot: JT-Shop: with the right blade, sure why not
02:36 PM Wolf__: with the right blades I would think so JT
02:37 PM JT-Shop: what is the right blade lol
02:37 PM fragalot: there are even blades that 'l cut HSS for you :P
02:37 PM JT-Shop: dang
02:37 PM MrHindsight: or is that only for seasoning "British Cuisine"?
02:38 PM Wolf__: http://www.starrett.com/category/saws--hand-tools/carbide-tip/2104
02:39 PM JT-Shop: I've not seen those blades before
02:39 PM Wolf__: best to check their cut chart
02:39 PM fragalot: even a good M42 blade should be able to do it shouldn't it?
02:41 PM Wolf__: probably
02:42 PM Wolf__: I could go check the bandsaw blade card in the shop
02:44 PM * JT-Shop doesn't see AR400 on his bandsaw chart
02:44 PM methods_: lol
02:44 PM fragalot: JT-Shop: it's only around ~38 rockwell if I recall correctly
02:45 PM fragalot: hard, but still quite soft
02:45 PM methods_: it work hardens very easily though
02:45 PM fragalot: that's a matter of feeds & speeds
02:45 PM fragalot: and using the right size teeth
02:46 PM methods_: hence JT-Shop statement
02:47 PM fragalot: when in doubt, go fast :D
02:47 PM JT-Shop: when in doubt use the plasma cutter
02:48 PM methods_: there ya go
02:48 PM roycroft: oxy-acetylene torch or die
02:48 PM fragalot: roycroft: what's wrong with plasma?
02:48 PM roycroft: it requires electricity
02:48 PM roycroft: you can use a torch off the grid
02:49 PM fragalot: until your gas runs out
02:49 PM roycroft: plus, a torch is more old school
02:49 PM fragalot: That, is true. :)
02:49 PM roycroft: when you run out of gas you're done working
02:49 PM JT-Shop: takes electricity to make the gas...
02:49 PM roycroft: how was it made before electricity?
02:50 PM fragalot: the hard way, but it wasn't compressed to 200bar either
02:50 PM roycroft: acetylene has been used as a welding gas since the mid 19th century
02:50 PM fragalot: roycroft: but plasma has been in use for millions of years
02:51 PM roycroft: billions of years
02:51 PM roycroft: ~14.5 billion, to be more precise
02:51 PM fragalot: rounding error
02:51 PM gloops: get shot with acetylene bottles on domestic property here
02:51 PM roycroft: or 14.5 thousand million years for folks across the pond
02:51 PM fragalot: gloops: that's why you get a bigger oxy-propane setup instead
02:51 PM gloops: a lot still have them though heh
02:52 PM gloops: fragalot propane is no good for welding really
02:52 PM fragalot: gloops: but we're talking about cutting, not welding
02:52 PM fragalot: nobody welds with a plasma, afaik.
02:52 PM gloops: well cutting not so bad
02:53 PM gloops: plasma or thermic lance
02:53 PM fragalot: actually, I remember this russian device now that could braze using a modified plasma type system
02:53 PM fragalot: can't remember the name though
02:53 PM fragalot: but it looked neat
02:54 PM gloops: those brazing kits were pretty standard issue with diy stick welders, not plasma but arc brazing cone
02:55 PM fragalot: it had one of those amazing infomercial ads
02:55 PM roycroft: interesting - i just read an article that recommends an indian rolling mill as a decent low end one over the chinese ones
02:55 PM fragalot: cut, heat, braze, spray weld with the same device!
02:55 PM FinboySlick: Electron beam brazing :)
02:55 PM roycroft: my ranking of non-western goods, in decending order of quality, is generally:
02:55 PM gloops: yes the indians use them roycroft
02:56 PM roycroft: japanes > taiwanese > chinese > indian > vietnamese
02:56 PM fragalot: I disabled targeted ads
02:56 PM gloops: back street metalworking very common
02:56 PM roycroft: japanese for the first one
02:56 PM fragalot: so now I get a lot of ads for "real human hair" from tradeindia
02:56 PM FinboySlick: You guys noticed those indian-made hand-scraped cast-iron surface plates for sale on ebay?
02:56 PM fragalot: roycroft: no german?
02:56 PM FinboySlick: They're surprisingly cheap.
02:56 PM roycroft: i said "non-western"
02:56 PM fragalot: point taken
02:56 PM roycroft: i include the us, canada, britain, and europe as "western"
02:56 PM gloops: Finboy someone mentioned them, apparently they are accurate
02:57 PM roycroft: i'm not going to get into an argument about german > british or whatever today :)
02:57 PM fragalot: FinboySlick: you mean the scraped look castings? :D
02:57 PM * roycroft gets in too many arguments here
02:57 PM fragalot: roycroft: tbh, in my experience, there is no such thing that "western" automatically means it's better
02:58 PM roycroft: that's also an argument in which i do not wish to engage today
02:58 PM gloops: indians will push old bike chains through 300 times to make a sword blade
02:58 PM fragalot: roycroft: aw shame :(
02:58 PM fragalot: gloops: without degreasing it first
02:58 PM FinboySlick: fragalot: https://www.ebay.ca/itm/Cast-Iron-Surface-Plate-Hand-Scrapped-12-X-12-Inch-Inspection-Plate/173099629724?hash=item284d8abc9c:g:vbIAAOSwOA1Z8HJq
02:58 PM gloops: red hoy hold it it with an old towel
02:58 PM gloops: red hot lol
02:59 PM fragalot: "high degree of accuracy"... but no mention of tolerances anywhere
03:00 PM fragalot: so,.. scraped look.
03:00 PM gloops: https://s.yimg.com/fz/api/res/1.2/Dq4IKdO8iEfFObyrkQcAtw--~C/YXBwaWQ9c3JjaGRkO2g9MzU1O3E9ODA7dz02MzE-/http://bikerdigital.com/wp-content/uploads/2017/06/chain-knife-.jpg
03:01 PM gloops: got to make one
03:01 PM fragalot: difficult to get it to forge weld
03:01 PM FinboySlick: gloops: If you use a greasy chain, you get extra-carbon in your steel ;)
03:01 PM gloops: thats right, the grottier the chain the better
03:15 PM FinboySlick: gloops: You lauched me down a youtube rabbit hole that culminated in home-made induction heaters.
03:15 PM fragalot: haha
03:15 PM fragalot: those are fun
03:16 PM gloops: its all about networks lol
03:16 PM fragalot: when I played with those I managed to melt quite a few things
03:16 PM FinboySlick: I was wondering if one could hack a vfd to be a good induction heater source. They're meant to be fairly beefy.
03:16 PM fragalot: sadly it wasn't the thing I wanted melting
03:17 PM gloops: bit scary for me
03:17 PM FinboySlick: Though I guess the VFD expects a specific kind of motor-like feedback.
03:17 PM fragalot: FinboySlick: I don't think so; it's more about current than voltage
03:18 PM FinboySlick: fragalot: How so? Induction heaters are still a bit of a mystery to me.
03:18 PM fragalot: FinboySlick: current dictates the strength of the magnetic field
03:18 PM FinboySlick: I know that they're essentially 'least-efficient-possible' transformers but nothing beyond that.
03:19 PM fragalot: and the way you heat the object is by creating friction within that object by rapidly changing it's field
03:19 PM fragalot: preferably at it's resonant frequency
03:19 PM fragalot: they are not that difficult to make really if you know basic electronics (or read up on them)
03:19 PM fragalot: if you just want to play around, you can buy really cheap ones on ebay
03:20 PM FinboySlick: So a good heater would monitor the voltage to hunt for the resonant frequency?
03:20 PM fragalot: just need a beefy power supply, and a few spares as you WILL burn them up as they have a low duty-cycle, lol
03:20 PM Wolf__: induction heater is on my list of things I know nothing about but want to play with
03:20 PM gloops: make a gingery furnace
03:20 PM ziper: also I dont think VFDs are the right frequency
03:21 PM gloops: bag of fire cement, old metal bin, away you go
03:21 PM fragalot: gloops: or just plaster of paris & sand
03:21 PM ziper: plaster of paris decomposes
03:21 PM fragalot: make a new furnace every 5 or so burns
03:21 PM gloops: well yeah, probably not last so well
03:22 PM fragalot: then when you get the hang of it and after you've learned how to cast them properly, build one out of refractory
03:22 PM gloops: a hairdryer, shove a propane pipe in, you can melt copper
03:22 PM fragalot: because almost EVERYONE ruins their first refractory pour anyway
03:22 PM ziper: what do they do wrong
03:23 PM fragalot: get it too wet, over-vibrate, or collapse the walls, ziper
03:23 PM fragalot: or fire it up too soon
03:23 PM gloops: i had a medium-violent explosion with 7lbs of molten ally
03:24 PM fragalot: gloops: I can think of more fun ways to spend a day?
03:24 PM gloops: it put me off for a day, but i tried again
03:26 PM gloops: had pics but cant find them, i made 2 plates 400mm x 200 x 20, still got them
03:26 PM fragalot: nice
03:27 PM gloops: tried casting on a piece of machined sandstone, it bubbled for a while then BOOM
03:27 PM fragalot: moisture.
03:28 PM gloops: moisture and i reckon the strata in the stone, the top layer had blown straight off
03:28 PM gloops: top layer expanded rapidly, lower layers didnt, shrapnel in a 30ft circle
03:28 PM fragalot: ah yeah
03:36 PM MrHindsight: FinboySlick: have you been frosty freezy up there?
03:39 PM FinboySlick: MrHindsight: It's not too bad. We actually had rain not too long ago, just to make sure everything was frozen hard and slippery.
03:41 PM MrHindsight: snow today, 50F in couple of days, been really up and down around here
03:41 PM MrHindsight: out to shovel
03:48 PM gloops: project on TV taking place in a british university - the hands free hectare, a small patch of farmland worked entirely human free for 1 year
03:49 PM gloops: driverless tractors, driverless everything
03:49 PM gloops: better productivity than with humans
04:14 PM Deejay: gn8
04:27 PM roycroft: so that indian roller mill at otto frei gets decent reviews, and is on sale
07:35 PM -!- #linuxcnc mode set to +v by ChanServ
07:43 PM CP_Away is now known as Contract_Pilot
07:44 PM MrHindsight: pcw_home: is there a high speed >16b ADC PCIe card from Mesa yet? I recall this being a possible future card
08:00 PM Contract_Pilot: No Pharma today mistake not productive at all
09:44 PM jdh: isn't someone here in kansas?
09:46 PM Tom_L: maybe
09:47 PM jdh: if one wanted to be in Emporia but everything was booked, would it be better to be in Topeka or Ottawa?
09:48 PM Tom_L: Topeka is quite a bit bigger
09:48 PM Tom_L: and the capitol
09:49 PM Tom_L: distance wise they look about the same
09:49 PM Tom_L: wichita looks to be about the same distance as well. maybe a tad bit further
09:50 PM jdh: topeka has tolls and 10 miles more
09:51 PM jdh: I assume tolls induce delays
09:51 PM Tom_L: not if you have a rfid on your window :)
09:52 PM jdh: I do, but only for florida
09:52 PM Tom_L: Ottawa is pretty small
