12:19 AM enleth: Connor: tapping with a traditional tapping head?
12:21 AM enleth: or even just with a straight tap in a collet if you have a floating quill
01:33 AM gloops: ballscrew mounts cut out http://picpaste.com/plate_007-tBd1HoPi.JPG
01:58 AM archivist: hand hacksaw?
02:01 AM Deejay: moin
02:15 AM gloops: archivist cut out with 9 inch grinder
02:15 AM gloops: still in the rough atm of course
02:17 AM gloops: that isnt a wobbly cut, its to fit something
02:20 AM archivist: :)
02:25 AM gloops: the x screws will be on the outside of the frame, pretty exposed to knocks, i might make some protectors at a later time
02:26 AM gloops: i dount this ballscrew metal too, already some signs of oxidisation
02:28 AM archivist: toughness v accuracy v corrosion resistance v cost to make
02:30 AM gloops: well theyve been in the house for months, some tarnished spots appearing, will need oil/grease
02:30 AM gloops: think ive seen oil reservoirs for them
02:58 AM C_P-Away: Sup
03:48 AM `Wolf: hmm, should I set the jet mill up with TTS and a 6” air cylinder/belleville springs
04:02 AM archivist: much faster tool change and consistency
04:37 AM jthornton: morning
04:37 AM XXCoder: hey jthornton
04:46 AM jthornton: got a tiny egg yesterday
04:47 AM XXCoder: lol just starting eh
04:48 AM jthornton: only a 4 degree change in temperature the next 36 hours then cold
04:48 AM XXCoder: slightly warmer night, cold again tomorrow heh
04:48 AM XXCoder: happ solence day
04:48 AM jthornton: started day before she laid on in a bucket, found it yesterday
04:49 AM jthornton: that was yesterday :)
04:49 AM XXCoder: not to me, havent slept ;)
04:49 AM XXCoder: also this night is longest one
05:08 AM jesseg: Okay I don't usually spam but this is too good: Grace Hopper explains nanoseconds: https://www.youtube.com/watch?v=JEpsKnWZrJ8&feature=youtu.be
05:18 AM jym: jesseg: That was pretty good actually =)
05:19 AM jesseg: I thought so :D
05:46 AM Tom_L: 27F
05:47 AM jthornton: 50F
06:00 AM jym: 33F @ 57%
06:01 AM jthornton: 100% here
06:01 AM jym: Raining?
06:01 AM C_P-Away: Morning
06:01 AM jthornton: no, foggy
06:02 AM jym: ah
06:02 AM C_P-Away: Almost time for morphine and night not for me..
07:56 AM gloops: slow progress, wanted to get the screws on this weekend
08:36 AM slipalong: Hi Guy's can anyone recommend a motor in the 1100 to 1500 watt range to upgrade my AMA25 spindle motor
08:37 AM slipalong: DC Brush motor is ideal so I can use a servo drive
08:38 AM cpresser: slipalong: there are chinese build 3-phase spindle motors incl. a VFD on ebay/aliexpress/...
08:38 AM cpresser: they provide good value for their price
08:39 AM slipalong: can you use these a C axis with the appropriate drive?
08:40 AM slipalong: got a lot of holes to tap!!
08:41 AM archivist: chinese things are high speed not really tapping
08:43 AM slipalong: Ive been looking a Hossmachine treadmill motor with gekodrive
08:43 AM slipalong: nice!
08:43 AM archivist: may just need to add an encoder to do tapping
08:43 AM archivist: iirc hoss uses a tapping head
08:43 AM slipalong: yes so I understand, but really want a better motor that a treadmill
08:44 AM archivist: where linuxcnc can do rigid tapping
08:45 AM slipalong: I believe it can. even if U have to get a motion control board it will be handy having a c axis
08:45 AM slipalong: just trying to keep the cost down
08:48 AM archivist: you can just homebrew a spindle encoder for tapping and add the connections in hal if your current spindle has speed and reversing control
08:52 AM archivist: choices
09:06 AM nallar is now known as Ross
09:25 AM gloops: cant wait to get into rotary stuff
09:30 AM JT-Shop: trying to understand the offset component, should be straight forward but I'm not getting any output, I've addf both functions to the thread... doing this in halrun
09:32 AM JT-Shop: hmm update time shows 0 must have messed up something
10:15 AM roycroft: yesterday:
10:15 AM roycroft: ack, mischan
10:41 AM gloops: when you got the right size drill but..but its the wrong taper
10:44 AM SpeedEvil: jb-weld
10:49 AM gloops: what? you stick the bore up?
10:50 AM * SpeedEvil may not have been 100% serious.
10:56 AM gloops: UK will get its iconic blue passport back after Brexit
10:57 AM gloops: not that i want one for anything
11:00 AM SpeedEvil: https://twitter.com/davidschneider/status/943989299682439169 - related
11:06 AM gloops: yes there are defeatists here unfortunately
11:07 AM roycroft: yes, gloop
11:07 AM roycroft: i'm so happy the most pressing brexit issue has been resolved
11:08 AM roycroft: although as one commentator said "what's the big deal with passports anyway? we should just go to the gate and shout 'wer're british! let is through!'"
11:16 AM archivist: bring back gun boat diplomacy
11:20 AM roycroft: both of our countries have them that want to take us back to a golden age that never existed
11:21 AM SpeedEvil: I disagree.
11:21 AM SpeedEvil: The leadership in both cases wants to return to a time when there was much less effective democracy
11:22 AM roycroft: it's hard to believe that it can be much less effective in either country than it currently is
11:23 AM roycroft: at any rate
11:23 AM roycroft: happy holidays all!
11:23 AM * roycroft is enjoying his additional six seconds of daytime today
11:23 AM SpeedEvil: 56N here
11:24 AM roycroft: it's so nice to have survived darkest night yet again, and the ever brighter days ahead
11:25 AM gregcnc: is bitcoin over?
11:26 AM roycroft: huh?
11:26 AM gregcnc: crashed hard today
11:26 AM DaViruz: hardly over
11:26 AM roycroft: it's trading at US$13000
11:26 AM DaViruz: it was at $20k a few days ago
11:27 AM roycroft: no, it wasn't
11:27 AM roycroft: it was at about $19k
11:27 AM DaViruz: yes, it was
11:27 AM gregcnc: any truth to manipulation by NKorea?
11:27 AM DaViruz: it was that too.
11:27 AM roycroft: but it was at $1300 last march
11:27 AM roycroft: and it's at $13000 right now
11:27 AM roycroft: it has a long way to go before one can call it "crashed"
11:28 AM roycroft: it just started publicly trading a few days ago
11:28 AM roycroft: it's going to find a price in the near term and settle in at that price for a while
11:28 AM Connor: I lost around $150.00 in BC today.. I've cashed out for now.. will wait to see where it ends up and buy low again.
11:28 AM roycroft: and i suspect that price will be closer to $13000 than $1300
11:29 AM roycroft: i still have some i haven't cashed in
11:29 AM roycroft: i have to recover my wallet, and haven't found the recovery key yet
11:29 AM roycroft: i was planning on selling when it hit $10k, but didn't get around to it
11:29 AM DaViruz: i would probably buy now, if it wasn't for sepa/iban transfers not being available for four days now..
11:29 AM roycroft: it's still above the price at which i wanted to sell :)
11:30 AM roycroft: i have about $800 invested in mining hardware and electricity
11:30 AM roycroft: my intent was, and still is, to only cash out enough to recover my investment
11:30 AM roycroft: and sit on the rest
11:36 AM Rab: Regarding bitcoin: http://fortune.com/2017/12/21/bitcoin-tax/
11:38 AM roycroft: yeah, but it's a capital gain
11:38 AM Connor: Coin Base stopped buying/selling for a bit..
11:38 AM roycroft: so not really taxed
11:38 AM roycroft: not like actual work is taxed
11:39 AM roycroft: my intent is to sell it for us dollars anyway
11:39 AM roycroft: and there was no loophole allowing that to be done tax-free
11:40 AM roycroft: the new dennis moore act is screwing me over in a myriad of other ways
11:40 AM roycroft: but that is not one of them
12:15 PM gloops: another train crash!
12:15 PM gloops: head on crash 2 trains Austria
12:19 PM phipli: :(
12:24 PM andypugh: I hadn’t realised just how enormous JT5 is. What sort of drill chuck would use that?
12:24 PM andypugh: https://www.ebay.co.uk/itm/NMTB30-NEAL-SKOKIE-JT-5-NO-30-NO-5-LOC2607/262495165205
12:25 PM andypugh: So, it costs $20 to buy it, and then $27 to ship it to me.
12:31 PM roycroft: it's hard to say that something good comes of a tragedy like a major train crash
12:32 PM roycroft: but the washington state department of transportation just ecreed that the amtrack cascades may not run on the new high speed route until positive train control is implement on the entire route
12:32 PM roycroft: decreed
12:32 PM roycroft: it can still operate, but on the old, windy, slow route along puget sound
12:33 PM andypugh: I don’t know the background, but are the Amtrack trains old and subbish and there are better faster ones to use the high speed route?
12:34 PM roycroft: the states of washington and oregon spent $800 million to upgrade the tracks and to purchase new trains for that route
12:34 PM roycroft: they are spanish high speed trains
12:35 PM roycroft: the new trains will operate on the old route for now, until ptc is fully implemented
12:35 PM roycroft: it's partially installed on both the old and the new route
12:35 PM roycroft: and the trains themselves are outfitted with it
12:36 PM roycroft: i don't know exactly how they were deploying it, but if it were me, i'd make sure that the trains would use ptc whenver it's available and switch to total manual mode when it's not available
12:37 PM roycroft: then i would install ptc on the tracks in places where, for example, the speed limit suddenly decreases from 79mph to 30mph because of sharp curve first
12:37 PM roycroft: and do the long, boring straightaways after all the scary parts were done
12:38 PM andypugh: So, I did some wiki-ing on PTC and found “Forms of Train Protection System, such as the Great Western Railway ATC system, have been operational in Europe for over one hundred years. “
12:38 PM roycroft: and our railroads are still fighting it
12:38 PM roycroft: and demanding further delays
12:39 PM roycroft: amtrak threatned to cease operations if mandated to install it
12:40 PM roycroft: europe are so far ahead of us that they're phasing out the older generation train control systems for a new generation that's a standard throughout the eu
12:40 PM roycroft: yet here we've barely started on our first generation
12:40 PM roycroft: i'm not sure that any passenger route has ptc enabled on the entire route
12:41 PM roycroft: after the philadelphia crash in 2015, which would have been avoided with ptc (which was installed but not turned on), there was a huge public outcry for finishing the implementation, which was mandated to be completed that year
12:41 PM roycroft: the result was the government permitting a delay until 2018-ish
12:42 PM roycroft: and the current adminstration are considering further waivers for pretty much any railroad who ask
12:42 PM roycroft: who are all of them
12:43 PM roycroft: high speed rail is also not supposed to have same grade croossings
12:43 PM roycroft: yet this one in washington and oregon has dozens of same grade crossings, because the states did not want to pay for isolate grade crossings
12:43 PM roycroft: that had nothing to do with this crash
12:44 PM roycroft: but it's what local officials have been decrying for years
12:44 PM roycroft: that can be worked around though - just reduce the speed to a crawl where there are same grade crossings
12:44 PM roycroft: ptc just needs to be done
12:45 PM roycroft: it's a simple, reliable means of preventing a lot of crashes and saving a lot of lives
12:47 PM Rab: Mandating system-wide PTC may be counterproductive. Most Amtrak trains piggyback on largely rural freight routs over distances which would terminate a European route in Siberia. It might be more pragmatic to prioritize the coasts, and high-traffic areas like Chicago.
12:48 PM enleth: roycroft: recently, the Warsaw underground (which, legally, is just two somewhat special train routes and uses standard train gauge) implemented a fully automated control system, including retrofitting old post-Soviet cars - it's not even used because the local laws do not permit a driverless train, but it's still active and capable of stopping a train in case the driver is incapacitated - or even
12:48 PM enleth: getting the train to the next station and stopping it there in case of a fire *and* an incapacitated driver
12:48 PM roycroft: ptc is mandated on freight trains as well as passenger trains
12:49 PM enleth: they didn't even have to do it, they just did it to future-proof the system
12:49 PM roycroft: and i understand that implementing it is expensive
12:49 PM roycroft: which is why prioritising implementation is the sensible thing to do
12:50 PM roycroft: and i think it's an easy argument to make that high speed trains need to be the highest priority
12:50 PM roycroft: they are the most prone to dramatic crashes if things go wrong
12:50 PM andypugh: I was surprised to find that you still have wooden railway bridges in the US. Though that might be a climate thing.
12:51 PM roycroft: what wsdot did i think was very sensible - they did not ban the trains completely, but required them to run on the old route at slow speeds until ptc is done
12:51 PM roycroft: it's a money thing
12:51 PM roycroft: a few lives here or there are no big deal
12:51 PM andypugh: In the UK climate you would be replacging them every couple of years.
12:51 PM roycroft: spending money to upgrade/repair infrastructure is a big deal
12:52 PM roycroft: most of our bridges here on the west coast are steel and/or concrete
12:52 PM andypugh: This train line near Phoenix often had trains with 100+ goods wagons, but all the creek crossings were wood: https://goo.gl/maps/hN52JQt6BB12
12:52 PM roycroft: but in eastern oregon, for example, there are many wooden bridges
12:52 PM roycroft: climate definitely is a factor
12:55 PM SpeedEvil: wood variety matters
12:55 PM roycroft: many of our concrete bridges were buitl during the depression by the wpa
12:55 PM roycroft: built
12:56 PM roycroft: they've been deteriorating over the years - salt water does affect concrete
12:56 PM roycroft: the state has been fairly aggressively restoring them over the past couple decades, as well as the steel bridges which are even more susceptible to salt spray
12:57 PM SpeedEvil: There are also reasonable questions on train protection costs now that the internet is a thing.
12:57 PM roycroft: they encapsulate the bridge sections in a coating that keeps the salt out
12:57 PM SpeedEvil: For example, if it can be implemented by a raspberry pi, rather than complex on-track infrastructure
12:57 PM SpeedEvil: (clearly, in a failsafe manner)
12:58 PM roycroft: ptc does a lot more than regulate speed based on track topology - part of it is traffic control so as to ensure that trains don't collide with each other
12:59 PM roycroft: and it can even sense obstructions on track sections
12:59 PM roycroft: that kind of stuff can be difficult to do with a self-contained system on the train itself
12:59 PM SpeedEvil: Totally.
12:59 PM roycroft: especially since a long, heavy freight train can take up to 2 miles to stop
12:59 PM SpeedEvil: A safety-useful-subset can be done entirely on-train though
01:00 PM roycroft: as a redundant system, sure
01:00 PM roycroft: and certainly as the primary system while the more robust sytem is being installed
01:00 PM roycroft: that's another problem we have
01:01 PM roycroft: our railroads are very slow to adopt new technology and methods
01:01 PM roycroft: our standards for passenger carriages, for example, date back to the 1920s
01:01 PM roycroft: we can't run most modern, lightweight european coaches on our tracks
01:01 PM roycroft: because the old standards mandate big, heavy coaches
01:02 PM roycroft: lighter weight coaches cost a lot less to operate and area actually a lot safer at high speed than the heavy ones
01:02 PM roycroft: but to bring in more modern coaches requires waivers that are very expensive and take a very long time
01:34 PM CaptHindsight: anyone working today? Most seem to taking the day off or left early
01:51 PM gloops: i see bitcoin has crashed
01:51 PM gloops: 50% off
01:53 PM CaptHindsight: the whole point is to keep it volatile
01:54 PM CaptHindsight: but the new US tax code now includes a tax on bitcoin when traded for something tangible
01:54 PM jason___: good thing that never actually happens
02:02 PM * roycroft will define $2000 as bitcoin "crashing"
02:03 PM CaptHindsight: another reason why Bitcoins are traded as futures vs as Bitcoins
02:03 PM gloops: gold is down
02:04 PM CaptHindsight: on the stock markets
02:04 PM roycroft: and bit coin is not "50% off"
02:04 PM roycroft: it peaked at just over $19k, and is currently at $13k
02:05 PM roycroft: but that $19k peak was momentary
02:05 PM gloops: just 9800 on the news
02:05 PM gloops: said
02:05 PM roycroft: the highest "stable" price, in the context of bitcoin stable, was $18k
02:05 PM roycroft: i just looked at one of the exchanges and it's at $13k
02:05 PM roycroft: but that could change in 5 minutes
02:06 PM roycroft: no sane person just invested heavily in bitcoin, so it's no big deal
02:06 PM roycroft: that said, i've read stories about people cashing in their pensions and getting second mortgages on their house to buy bitcoin over the past couple weeks
02:06 PM roycroft: those people are not in the set of people who are sane, though
02:07 PM roycroft: they're lottery ticket buyers with money
02:08 PM gloops: true, thats why i invested in a pile of iron and some stepper motors
02:09 PM * roycroft is glad he's been collecting retirement grease all these years
02:09 PM roycroft: i don't eat bacon, so i just scrape it out of my hair
02:11 PM Tom_L: iron futures is where it's at
02:12 PM Tom_L: that and apparently raising chickens
02:12 PM roycroft: i don't eat magnets either
02:13 PM roycroft: nor chickens
02:13 PM roycroft: but i do eat eggs
02:13 PM roycroft: which probably makes the chickens happier than if i ate chickens
02:14 PM gloops: chickens are dinosaurs with feathers
02:14 PM gloops: dinosaur = terrible lizard
02:16 PM andypugh: Yes, but back when “terrible” was a good thing.
02:18 PM Rab: Similar to how germans might say "gross".
02:19 PM CaptHindsight: vs eeww gross spoken by a teen?
02:20 PM andypugh: Or 144
02:20 PM CaptHindsight: everyone done with their xmas shopping?
02:21 PM andypugh: Not yet.
02:21 PM CaptHindsight: made the mistake of driving through a mall parking lots yesterday
02:21 PM andypugh: I was going to go to the supermarket at abput 9pm, in the hope that it will be a bit quieter
02:24 PM roycroft: i've done all the holiday shopping i'm going to do
02:25 PM roycroft: i still have some arrangements to sort out for christmas dinner
02:25 PM roycroft: we traditionally have crab, but i'm not certain the fishmonger's will be open on sunday
02:25 PM roycroft: if not then i'll have to get live crabs tomorrow and keep them in a cooler until monday
02:26 PM roycroft: which will entail making up some salt water
02:26 PM andypugh: Why would a fishmonger sell crabs? Surely they should come from the arthropodmonger?
02:27 PM andypugh: :-) https://evolution.berkeley.edu/evolibrary/images/dinnerisruined.gif
02:27 PM roycroft: our fishmongers don't discriminate on phylum
02:28 PM roycroft: we're an inclusive society
02:32 PM CaptHindsight: my feeling is that they should just be called mongers
02:36 PM gloops: we've changed our shopping habits at xmas, we dont pile up a months worth of supplies anymore
02:36 PM gloops: the shops are only closed for 2 days
02:46 PM Crom: ugh harbor freight doesn't have a replacement drawbar for a 33686 *rung fu rf-31 mill/drill
02:47 PM SpeedEvil: http://forum.nasaspaceflight.com/index.php?topic=37727.1100 - neat large carbon fibre fairings.
02:47 PM C_P-Away: Cannot Sleep at all 1 15mg morphone not working if i roll over at rest etc it takes the edge off.
02:47 PM C_P-Away: Morphine
02:48 PM Crom: morphine doesn't deo shite
02:50 PM Crom: once you take enogh to work, you stop breathing
02:50 PM C_P-Away: Just takes the edge off
02:52 PM C_P-Away: I have severe reaction to Codeine, Hydrocodone, and Oxycodone.
02:57 PM gloops: a sports car maker is opening a place near me doing high tech carbon fibre chassis and bodies
02:57 PM gloops: what do they call them now
02:57 PM gloops: MCLaren
02:58 PM gloops: C_P - reading
02:58 PM gloops: https://www.insidermedia.com/insider/yorkshire/mclaren-to-open-50m-supercar-manufacturing-facility
03:00 PM rene-dev: pcw_home does the bit in the data register tell which channel failed? https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/drivers/mesa-hostmot2/sserial.c#L1820
03:01 PM andypugh: gloops: I wonder if Keith Ridgeway still remembers me? “Gissajob Prof”
03:05 PM gloops: you were one of his students andy? ( i dont know him lol)
03:05 PM andypugh: Not a student, know. I was a postdoc in the same department for 12 years or so
03:06 PM andypugh: (How did I manage to type “know” when I meant “no”? That’s just wierdly phonetic of me)
03:08 PM CaptHindsight: I need to make a printer for CF auto body panels
03:10 PM gloops: oh i see, didnt know you were there andy - im the other side of rotherham, i think the mclaren place is going on the failed sheffield airport site
03:11 PM andypugh: When I last lived in Sheffield it hadn’t yet failed.
03:13 PM gloops: postdoc in advanced manufacturing?
03:16 PM gloops: Capt you cant print carbonfibre, its done with pressure bagging and so on
03:16 PM andypugh: I mainly did structural integrity (crack growth in metals) though I started off modelling crash-test dumy materials behaviour and finished off with skin graft research in the medical physics department.
03:19 PM CaptHindsight: andypugh: sounds like you are ready to engineer the skins of cyborgs
03:19 PM CaptHindsight: gloops: can to
03:20 PM andypugh: As long as they are called Naomi Wu I am all in favour of cyborgs :-)
03:20 PM gloops: Capt how do you print the fibre into a hollow form?
03:21 PM CaptHindsight: amazing upper frontal superstructure
03:22 PM CaptHindsight: gloops: depends on the tech, support materials that are water soluble is one way
03:23 PM gloops: well, the way ive seen them do it they laminate it as normal, then inflate a bag inside to press the laminates to the mold
03:25 PM CaptHindsight: sounds like they start with woven CF
03:25 PM SpeedEvil: Probably prepreg
03:25 PM SpeedEvil: which is carbon fibre already impregnated with resin.
03:25 PM CaptHindsight: weave in place
03:26 PM CaptHindsight: depends on the application, what length CF is required?
03:27 PM SpeedEvil: possibly, yes.
03:27 PM CaptHindsight: it matters
03:27 PM SpeedEvil: A number of places were working out how to do it without an autoclave
03:27 PM SpeedEvil: which obviously matters at this scale
03:28 PM gloops: yes, i was wondering if anyone knew that
03:28 PM CaptHindsight: there are bunch of research papers
03:29 PM gloops: carbonfibre is overated
03:29 PM SpeedEvil: https://www.compositesworld.com/blog/post/no-oven-no-autoclave-nona- ah
03:30 PM gloops: i still think CF would make a good gantry though
03:32 PM gloops: plywood to screw to, with CF wrap
03:35 PM CaptHindsight: http://www.plasticomp.com/wp-content/uploads/lft-design-white-paper-figure-4.jpg
03:36 PM CaptHindsight: CF with epoxy curves are similar
03:39 PM gloops: glass is stronger, cf stiffer?
03:39 PM CaptHindsight: http://www.plasticomp.com/long-fiber-design-principles-white-paper/
03:40 PM JT-Shop: dang vmc stalled out the spindle on a 1/2-13 tap... turns out you have to use the program for that tap not the one for the other end that has 5/8-11 tapped holes
03:40 PM CaptHindsight: gloops: http://www.plasticomp.com/wp-content/uploads/CF-Specific-Strength-vs-Density.png
03:42 PM gloops: not sure what the bar chart is saying
03:43 PM CaptHindsight: need programmable spiders to weave silk into specific shapes
03:45 PM gloops: what you want is a printer in a glass tank that has a lot of turbulence, start printing - empty a bag of chopped fibre into the tank and put the lid on
03:46 PM XXCoder: I read about spiders being fed grapohete making really strong web
03:46 PM XXCoder: which means very strong material
03:46 PM gloops: normal web is very strong
03:46 PM XXCoder: yep
03:46 PM gloops: if that were an inch thick you could tow a train with it
03:47 PM XXCoder: yeah and graphete apparently makes THAT much stronger
03:47 PM gloops: well, its pretty strong anyway
03:48 PM CaptHindsight: https://en.wikipedia.org/wiki/BioSteel
03:48 PM CaptHindsight: but goats are bigger than spiders so it won't help with weaving small parts
03:52 PM gloops: it will all be irrelevant as carbon nanotubes come to the fore
03:52 PM XXCoder: evenually. growing em is... very diffult to do in bulk rates
03:53 PM CaptHindsight: getting out of bed was hard for me today
03:53 PM XXCoder: CaptHindsight: had similiar issues. woke up so oftem during nights
03:53 PM C_P-Away: Who else has harbor freight moving blanket black out curtins?
03:53 PM XXCoder: waking up and getting up was tough today.
03:54 PM CaptHindsight: C_P-Away: I use concrete and steel
03:54 PM XXCoder: I use cardboard
03:54 PM C_P-Away: http://www.stevenrhine.com/wp-content/uploads/2017/12/FB64918B-225E-44C4-8D9C-53D655157472-1024x768.jpeg
03:54 PM C_P-Away: Free Moving Blankets not to bad...
03:55 PM CaptHindsight: I have a blue vinyl tarp over two windows currently
03:55 PM CaptHindsight: from HF
03:55 PM C_P-Away: Temp till i can get to using power tools again
03:55 PM CaptHindsight: the moving blankets are often on sale, they are great as moving blankets
03:56 PM C_P-Away: No lifting over 10lbs for the next 6 weeks no bending or squating for any longer then to get dressed.
03:56 PM CaptHindsight: XXCoder: weird dreams or just woke often?
03:57 PM XXCoder: both actually
03:57 PM C_P-Away: I get to take my outer bandage off tonight.
03:57 PM gloops: what happened CP? what is the injury?
03:57 PM C_P-Away: Umbilicial Hernia Repqir
03:58 PM C_P-Away: I am on drugs excuse the spelling
03:58 PM gloops: whoo sounds painful
03:58 PM XXCoder: ow
03:58 PM C_P-Away: 2nd injeury was falling sprain in ankle and stick thru arm
03:58 PM Tom_L: JT-Shop did you snap the tap off?
03:59 PM C_P-Away: http://www.stevenrhine.com/wp-content/uploads/2017/12/5C4CB2BE-3C47-44B1-9507-5A8A06DFD1FB-1024x576.jpeg

04:00 PM C_P-Away: No easy Recover for me...
04:02 PM gloops: who wouldnt thought that splinter would go straight through your arm like that
04:03 PM gloops: would have thought
04:03 PM XXCoder: ouch indeed
04:06 PM C_P-Away: Yea it hurt
04:06 PM C_P-Away is now known as Contract_Pilot-A
04:08 PM skunkworks: I was sliding 2X4's over my hand and caught a sliver that went from one end of my hand to the other..
04:08 PM skunkworks: fun pulling out
04:08 PM Contract_Pilot-A: Yea, ER doc wanted to pull no pain killer i said like hell..
04:09 PM Contract_Pilot-A: Have me IV Morph / Tramadol waited 4 hours then local removed it.
04:09 PM Contract_Pilot-A: why they waited 4 hours for the morph and tram to where off was beyond me.
04:10 PM Contract_Pilot-A: But i am Criminally Tresspassed from that ER now anyway.
04:10 PM CaptHindsight: not me http://i.dailymail.co.uk/i/pix/2014/08/26/article-2734580-20CF9FA700000578-405_634x423.jpg

04:17 PM gloops: dismantling property? looks like inch concrete reinforcing
04:23 PM gloops: doing this maybe https://www.youtube.com/watch?v=Rt9l4YkyGj4
04:25 PM gregcnc: Capthindsight you were asking about a mill cutting a wheel the other day. i can't figure what kind of mill this is either.

04:26 PM ziper: what do you call these kinds of tools https://images.craigslist.org/00404_gIo0Vwnx8kz_600x450.jpg
04:27 PM gregcnc: side milling cutter
04:28 PM ziper: thanks
04:28 PM Deejay: gn8
04:29 PM JT-Shop: I think I need to start thread milling the bigger sizes
04:33 PM gregcnc: vs tapping?
04:34 PM CaptHindsight: hehe Bimbo CNC
04:34 PM JT-Shop: yea looks like 1/2-13 is my limit on the 308
04:35 PM gregcnc: I'm guessing OSHA approved open toe steel toes
04:35 PM JT-Shop: 5/8-11 overloads the spindle unless you have a very new tap
04:35 PM CaptHindsight: electrospun goat/spider silk printer
04:35 PM JT-Shop: I wonder if the 308 can do a helical spiral
04:36 PM gregcnc: One of the guys in the RC club has started printing airplanes
04:36 PM CaptHindsight: gregcnc: cnc glue gun?
04:36 PM gregcnc: yes
04:36 PM gregcnc: I haven't seen any parts yet
04:36 PM JT-Shop: lol the programmers manual for the 308 is from 1993
04:37 PM CaptHindsight: short stand CF with SLA would be great and far smoother
04:38 PM CaptHindsight: how much does the roughness of the surface effect small RC planes?
04:38 PM gregcnc: I think some people fake milling tpaer threads with 90° arcs
04:38 PM gregcnc: not enough to really matter
04:39 PM gregcnc: at certain sizes/speeds it actually helps
04:39 PM JT-Shop: looks like G2/3 is only two planes with the 308... man I wish I could convert it to LinuxCNC
04:40 PM gregcnc: excel file to calculate point to point?
04:41 PM gregcnc: I hope my lathe does the simpler drilling cycles, only peck drilling is in the manual
04:42 PM gregcnc: Emco Fauxnuc is ridiculous. it acts neither like the real Fanuc nor Emco's own manual.
04:43 PM JT-Shop: I like this note in the programming manual in the tapping section "If tapping first in the part program you must make a G1 move(in outer space is ok) before you rigid tap
04:44 PM XXCoder: lol
04:44 PM gregcnc: it won't run a tapping cycle without a G1 in the program prior?
04:45 PM XXCoder: not a major problem really. just go .001" g1 move
04:45 PM XXCoder: outer space is optional ;)
04:45 PM JT-Shop: hmm I found G12/13 helical interpolation
04:45 PM gregcnc: as long as you remember, hopefully it errs and not something dumb
04:46 PM JT-Shop: gregcnc: yup
04:46 PM XXCoder: JT-Shop: it'd be perfect for pocketing
04:46 PM XXCoder: just drill hole then use it with hlixical cutting
04:46 PM XXCoder: unless its that sideways helical cutting
04:47 PM XXCoder: yep it is nm my prittle lol
04:47 PM XXCoder: later all gonna work
04:47 PM JT-Shop: bye
04:48 PM JT-Shop: looks like I can do a G12 for each thread then go to center and back out
04:51 PM JT-Shop: need to write a python program to generate the G code
04:53 PM JT-Shop: hmm maybe not A is total degrees of rotation and Z is total depth
04:54 PM gloops: kid on youtube with the 'mini metal foundry' is good
04:57 PM gloops: americans are probably more thrifty than brits these days id say
04:57 PM gloops: theres bloke stripping all kinds of electrical household items, some very useful bits
04:58 PM gloops: scrap microwave has a decent fan..., never thought of that
05:10 PM ziper: i put my piston in the deep fryer to get the wrist pin out
05:10 PM gregcnc: HOW DOES IT TASTE?
05:11 PM ziper: gud
05:11 PM gloops: little end?
05:14 PM CaptHindsight: ziper: is either worth saving if the fit was that tight?
05:15 PM ziper: CaptHindsight, its what the manual called for, and I didnt want to beat it out if I didnt have to
05:17 PM CaptHindsight: Step 11: Dip piston and rod into deep fryer until the pin becomes loose
05:19 PM JT-Shop: say goodnight Gracie
05:19 PM CaptHindsight: hasta banana
05:20 PM CaptHindsight: https://www.theverge.com/2017/12/22/16811944/elon-musk-spacex-tesla-roadster-mars-falcon-heavy
05:21 PM CaptHindsight: I really hope it gets and stays in orbit
05:26 PM SpeedEvil: I hope it misses and hits Mars
05:26 PM SpeedEvil: No.
05:27 PM SpeedEvil: Phobos
05:27 PM SpeedEvil: FH is so awesome in a way it's a shame it's getting overshadowed by BFR
05:59 PM Contract_Pilot-A: So on the 7I92 What should i look for in choosing an ethernet controller?
06:00 PM Tom_L: what do you mean?
06:00 PM Contract_Pilot-A: Ehternet Card
06:00 PM Tom_L: it has ethernet i believe
06:00 PM Contract_Pilot-A: Will most the onboard ones be ok or should i look aftermarket
06:01 PM Tom_L: should be ok i would think
06:01 PM Contract_Pilot-A: Freind has a NUC i want to try
06:02 PM Contract_Pilot-A: Now that path Pilot has the 7I92 Configs got to get a 7I92H with a IDC26 to IDC26 Cable give it a go on this 1100 just for fun.
06:02 PM Tom_L: you need to run preempt instead of rtai though
06:02 PM Tom_L: with ethernet
06:02 PM Contract_Pilot-A: Would Love to put a mini poc in the control cabinet.
07:09 PM andypugh: CaptHindsight: If that car makes it out of the gravity well, Elon should sell it on eBay. “Buyer collects:
07:18 PM andypugh: Contract_Pilot: If you can find a PC / Motherboard with dual LAN then that might be a win, one for the Mesa card, one for internrts.
07:20 PM Contract_Pilot-A: Wireless for internets good
07:23 PM andypugh: Yes, that’s fine if you don’t want Gigabit
07:39 PM Contract_Pilot-A: as long as it is wireless A/C i am good for an internet connection
07:39 PM Contract_Pilot-A: even N300
09:14 PM SpeedEvil: https://twitter.com/Cronovey/status/944387736596660224 'I seriously think it's a nuclear bomb' (sort of on topic as it has lots of axes and linux)
09:15 PM MarcelineVQ: looks like a powerful tail light
