12:48 AM miss0r: Mornings
12:51 AM fragalot: mornin'
12:51 AM CaptHindsight: gnite
12:52 AM miss0r: :]
01:08 AM IchGucksLive: hi
01:18 AM miss0r: FINALLY got my login yo solar.dk
01:18 AM miss0r: Best place I know of for buying electrical stuff. If I place an order before before 18:00 the day before, it will be here before 04:00 the next day
01:26 AM IchGucksLive: im off later
01:29 AM miss0r: I need to figure out how to fix my post processor... For some reason, I forgot to add G0 to all rapid movements. It can take forever :D
01:33 AM gloops: one thing with a lot of shopping going online, there are fleets of parcel lorries and vans going everywhere, several times a day
01:33 AM gloops: so delivery on most things is quicker
01:35 AM miss0r: Yeah. Its a good thing for me doing day to day repairs
01:44 AM gloops: car spares seem most organised, can get most things same day if you order before dinner, the ones round here have a about 3 drops a day, i ordred the plugs for my van yesterday maybe 1.30 should be here in an hour or so
01:47 AM miss0r: yeah. that is genious
01:51 AM miss0r: Nice. I have a 40x30 6082-T6 aluminium rod laying around I forgot about.. Almost 2 meters
01:51 AM miss0r: 70x30*
01:51 AM miss0r: Then I don't need to go order alu for this order
01:54 AM MrSunshine: hmm, glass scales are generaly quite accurate right? =)
01:54 AM miss0r: Standing here listening to the radio. Now I am wondering; Is it a world wide thing that only stupid/dim witted people are allowed to host a radio show? or is this a danish concept?
01:54 AM miss0r: MrSunshine: generaly, yeah?
01:56 AM miss0r: MrSunshine: You can get some rather low quality chinesium ones, that are not completely trustworthy, but they are rare and far apart
01:57 AM MrSunshine: alright =) im looking at correcting pitch error etc in the machine .. ive got a 1250mm travel .. would i need to have a 1250 (atleast) scale or can it be done with say a 700 scale, do the first half then move the scale to do the second part of the screw maybe? =)
01:58 AM MrSunshine: if anyone has any idea about it =)
01:58 AM miss0r: well, if it is just for pitch correction, you can do it with a short scale
01:59 AM miss0r: but you need to take good care when moving the scale, so you keep your original position of the machine
02:00 AM MrSunshine: miss0r: the thing im thinking is with big moves so it doesnt get an accumilative error somewhere =) even was thinking if it would be doable with a digital caliper but im afraid it would introduce to much error in the mix =)
02:00 AM gloops: how bad is the screw MrSunshine?
02:00 AM MrSunshine: gloops: do not know .. getting dimensional errors on parts up to 0.5 - 1mm :/
02:01 AM gloops: 1mm!
02:01 AM miss0r: :o
02:01 AM gloops: surely not the screw
02:01 AM MrSunshine: thats parts that is like 900mm wide
02:01 AM gloops: hmm
02:01 AM miss0r: what screw is it?
02:01 AM MrSunshine: gloops: chinese rolled ballscrews
02:01 AM miss0r: Still...
02:01 AM MrSunshine: tho ive not tested that big dimension since i added second screw to the machine :P
02:02 AM gloops: this will repeat if its the screw lead though?
02:02 AM miss0r: I'd give it a go with the glass scale. you 'could' buy a long one, they are not that expensive, in addition you could wire it into the controller and have great accuracy all the time ;)
02:02 AM MrSunshine: but getting out of round etc also when doing test pieces that is 100mm diameter
02:02 AM gloops: every 900mm will be +1mm
02:02 AM MrSunshine: up to 0.1mm out of round
02:03 AM MrSunshine: gloops: found a youtube film on one fixing a screw, the error in pitch was accumilative and ended up quite bad over short distances :/
02:03 AM MrSunshine: tho do not know what kind of screw he had
02:03 AM miss0r: Give it a go with a glass scale
02:04 AM Deejay: moin
02:04 AM MrSunshine: if not anything els ei can confirm dimensional errors with a scale in both axis .. a pity it costs so damn much tho :/ and i guess i would need a linear rail for the glass scale also :/
02:05 AM MrSunshine: https://www.youtube.com/watch?v=0uasuhswYfg
02:05 AM gloops: what machine is it MrSunshine?
02:06 AM MrSunshine: gloops: home built =)
02:06 AM gloops: Ichs has said hes had c7 screws that are out .3mm over 300mm
02:06 AM MrSunshine: mine that is
02:06 AM MrSunshine: gloops: chinese ... buy it if you want trouble ... but its soooo cheap! :P
02:06 AM gloops: lathe router?
02:07 AM gloops: 1mm over 900 wouldnt bother me actually haha
02:07 AM MrSunshine: https://www.facebook.com/system2/media_set?set=a.10154899439923648.1073741840.682103647&type=3
02:07 AM MrSunshine: router
02:09 AM gloops: fine looking machine
02:09 AM gloops: whats the screw over the top for?
02:09 AM MrSunshine: the top screw is the gantry
02:09 AM MrSunshine: added another on the other side of the gantry to move it straight
02:10 AM gloops: hmm, not sure thats the best place for the gantry drive
02:10 AM MrSunshine: gloops: i noticed :P
02:11 AM gloops: so theres no racking with the gantry now?
02:11 AM MrSunshine: gloops: but like i said, another screw int he front of the machine to pull that side also =)
02:11 AM MrSunshine: gloops: like 0.1mm if i push it hard
02:13 AM gloops: these things are difficult to analyse - if there is some deflection, racking, backlash etc, could easily be 1mm error at the end
02:14 AM MrSunshine: mm, thats why i was thinking of checking pitch error first to get that out of the way .. need to start somewhere =)
02:14 AM gloops: out of round - that is a hole or circle you cut? if the screw lead is randomly out these would be different at different locations on the table
02:20 AM MrSunshine: i guess i could just test one corner with e a caliper just for now to see just for the cause =)
02:21 AM miss0r: You know what sucks about my mill? The y-axis screw is a lefthand thread, and I have to replace it soon with a right hand. To reverse the direction of the servo, I need to get into the control box, which stands 15cm from the garage door. So I have to go outside and open it up and sit in the cold to do the wiring... *sigh*
02:22 AM MrSunshine: haha =)
02:22 AM MrSunshine: the curse of not having enough space? =)
02:22 AM miss0r: yeah. its a curse alright
02:22 AM gloops: well with good intentions i ripped all the wiring off mine and decided to do a 'proper' wiring job inside a stainless steel box, - never again
02:23 AM gloops: some proper arsing about wiring little stuff up inside a box
02:23 AM miss0r: :D gloops, its what I do for a living :D
02:23 AM gloops: not my thing at all haha, too much fiddly messing about
02:23 AM miss0r: You should've outsourced it to me
02:24 AM gloops: it took me a morning to do everything on a board before, ive spent about 3 days on this box already
02:24 AM gloops: i cant afford your e250 an hour miss0r lol
02:24 AM miss0r: lol. I'm only 75eur/hour
02:25 AM miss0r: and for the projects in here, I won't charge anything, if you can wait a bit for it ;)
02:25 AM gloops: ive had to cut a screwdriver down to about 2 inch to get it in
02:25 AM miss0r: just a few pictures of what I do: https://imgur.com/a/0tdmp
02:25 AM miss0r: (what I had at hand)
02:26 AM gloops: see i never really appreciated these photos of immaculate electric boxes, now ive tried one i do
02:27 AM miss0r: now you know ;)
02:27 AM gloops: mine has wires everywhere still, but i think in theory it is all fairly correct
02:27 AM miss0r: The shipping container there took me almost 4 weeks to complete, from start to finish
02:28 AM miss0r: Willing to share a picture of your box?
02:28 AM gloops: well as a layman i would say that is superb work
02:28 AM miss0r: as a professional, in fear of sounding to self centered, it is ;)
02:28 AM gloops: not got any of it yet, ill get some when i get back into the garage
02:29 AM miss0r: You'd never hire me to install a lamp in your kitchen, I would leave black fingermarks all over the place. but this is what I do
02:29 AM miss0r: and now I also do machine building :D I started on my own(selfemployed) 1/3
02:30 AM gloops: everything is twisted pairs, with copper tape shielding and grounded, or proper copper braid sheilded, ive kept the big noise elements seperated from the signal stuff, its very rough but i think it has to be better than what i had
02:30 AM miss0r: Indeed
02:30 AM gloops: yeah i think you should do ok miss0r with a portfolio like that to flash
02:32 AM miss0r: I'm not worried at the moment. For the time being I have my calender booked 3 weeks into the future
02:33 AM gloops: 3 weeks is breathing space, 6 weeks is dont give a shit anymore space lol
02:33 AM gloops: youve got 3 weeks to get another job in
02:34 AM miss0r: Yeah. As I said, i'm not particularly worried. But keep in mind 3/4 of what I do is repair jobs on machines. the last 1/3 is changing machines/building addons ect. So I just need to hope people keep breaking stuff & my phone rings
02:36 AM gloops: it will build up as time goes on, you end up with a large base of former customers, any of who could ring again at any time, and all telling people about you
02:37 AM miss0r: You just listed my buisness plan ;)
02:38 AM gloops: then you will stop answering the phone lol
02:38 AM miss0r: hehe, I hope I get to have that luxury one day
02:41 AM gloops: a thing here in some services - to get work in, is the old 'free inspection'
02:42 AM gloops: i dont know if that would work with machines
02:42 AM gloops: suspect some problems with a machine - ill check it over for free
02:42 AM gloops: (of course you will find some issues with it)
02:44 AM gloops: British Gas does an annual free boiler check for all their customers - that generates millions of pounds of work for them
02:44 AM miss0r: nice
02:44 AM miss0r: but most machinist will then fix the machine themselfs I think
02:44 AM gloops: haha maybe yeah
02:45 AM gloops: people cant do that with gas because its regulated, so probably not a good example
02:45 AM miss0r: yeah
02:45 AM miss0r: Meh. I need to make a new coolant system for my mill... I want to have 4 nozzles hitting it from all the sides
02:46 AM gloops: manual controlled? like with taps? or from software
02:46 AM miss0r: Its software controlled
02:47 AM miss0r: I just need a more powerfull pump, then I can add some more nozzles I think
02:47 AM miss0r: The old pump is playing on its last tune anyway
02:49 AM gloops: i wouldnt know where to start, my plugs are here anyway, one more cup of tea i think first
03:05 AM gloops: right, tap plug in, bolt manifold back on, cant get ratchet in so spanner, reconnect exhaust and stabiliser, hmm 1.5 hours, should be mobile for 10.30
03:05 AM gloops: cant do dealz without wheelz
03:07 AM miss0r: :]
03:10 AM miss0r: bah. Almost completed transferring another batch of code to the mill, then it faults out on me because I have N368 G0 G0 z10. (It can't tolerate double commands)
03:10 AM miss0r: sadly it doesn't make it go double fast
04:02 AM gloops: right, filled her up, think ill have a tea then turn it over, hope i didnt drop anything down exhaust port or turbo
04:09 AM miss0r: :D
04:12 AM gloops: only thing im not sure of - oil pipe bolt to turbo, bolt with 3 holes, oilways on bottom of shaft, i hope that doesnt need aligning
04:13 AM gloops: 3 holes should let oil through whatever position the bolt is in i think...
04:14 AM gloops: will not last many seconds without oil lol
04:15 AM XXCoder: washbi must be grown on river beds. It must grow in low humidity. it's like "fuck you if you try to grow me"
04:19 AM miss0r: second support arm is complete.
04:20 AM XXCoder: miss0r: one of mills at work use a bent tube with severial nozzle attachments for coolant
04:20 AM XXCoder: sprays from all around just fine
04:20 AM XXCoder: and out of way for toolchange
04:21 AM miss0r: XXCoder: Yeah. I was considering something like that.
04:21 AM XXCoder: or you could use the much ugler one, that just has pipe down to side by spindle and sprays all over on table
04:21 AM XXCoder: it dont move with spindle or table
04:25 AM jthornton: morning
04:28 AM miss0r: mornin
04:29 AM miss0r: XXCoder: Indeed. But I like having the nozzles somewhat directional :]
04:29 AM XXCoder: lol yeah and following spindle lol
04:30 AM XXCoder: sometimes table mount is better because its always spraying on part
04:30 AM XXCoder: but none of work cnc machines use table mount types.
04:31 AM miss0r: My nozzles are already mounted to the spindle ram, so that is not a problem
04:31 AM miss0r: I just need MOARH!
04:32 AM jthornton: 4:30am and time for the chickens to wake up and start laying
04:32 AM XXCoder: mollah is always the problem
04:51 AM gloops: hmm, core plug fix worked, but water still acting strange, run around for a few miles, its is as if the water isnt circulating properly, difficult to fill up, taking in a little bit at a time, temperature 5 degrees above normal, but running fine...
04:52 AM XXCoder: car engine coolant?
04:52 AM gloops: yeah
04:52 AM XXCoder: your umm termostat? must be shot
04:52 AM gloops: thats one thing im thinking, thermostat stuck shut
04:53 AM XXCoder: my van had that, it was stuck half closed
04:53 AM XXCoder: so it would cool too much at early part but then not cool enough later lol
04:53 AM gloops: ill go for that next, ive really got to make a journey in this vehicle today, about 10 miles and back ffs
04:54 AM gloops: first sign of anything wrong - fanbelt snapped when i started van, im wondering if water pump was frozen and the impeller shaft snapped
04:55 AM gloops: so effectively - no pump
04:55 AM XXCoder: lol reminds me of earlier car issue
04:56 AM XXCoder: water pump was shot so it rocked and kept losing belt
04:56 AM jthornton: that sounds plausible
04:56 AM gloops: if water was solid belt would soon burn up on it
04:56 AM gloops: water pump
04:57 AM gloops: feck it anyway im going out in it lol, ill leave it there if it blows up
04:57 AM gloops: gypsies will take it
04:58 AM XXCoder: careful some cars share belt with crank and it would quite literally get out of engine if belt breaks
04:58 AM gloops: the timing on these is chain so no worries there- doesnt run off crank pulley
04:58 AM XXCoder: I remember one model of van people would annually replace belt (way shorter than normal belt life) because it might wear and literally break engine
04:59 AM gloops: i had a car where auxilliary belt came off and wrapped round the timing belt pulley and brought it off - never buy another renault
04:59 AM XXCoder: ow
05:01 AM Loetmichel: gloops: my old Opel Omega once lost its main auxillary belt pulley
05:01 AM Loetmichel: while driving
05:01 AM gloops: there are also no timing marks on the renault pulleys, nothing at all
05:01 AM gloops: my mate said he'd have a look even though we knew it was dead - took crank pulley off then realised - no marks, no nothing to get the timing back
05:02 AM Loetmichel: it has a n outer ring with the pulleys, an inner hub, both made of steel and in between about 1" of soft rubber as a "torsion dampener"
05:02 AM Loetmichel: ... after a few years it will rupture
05:02 AM Loetmichel: NOT funny when you suddenly lose power steering in a sharp corner
05:02 AM gloops: ahh yeah the 'dual mass' pulleys Loet
05:02 AM Loetmichel: yes
05:02 AM gloops: lol no it isnt
05:03 AM Loetmichel: outer ring just fell off and took the auxillary belt with it
05:03 AM XXCoder: one of my uncles died by steering wheel suddenly not controlling wheels and he went off bridge
05:04 AM Loetmichel: thankfully no other damage to the engine
05:04 AM gloops: not funny when that happens XXCoder
05:04 AM Loetmichel: XXCoder: how did THAT happen?
05:04 AM XXCoder: no idea, it was long time ago
05:04 AM Loetmichel: broke a linkage?
05:04 AM XXCoder: it was simply sudden, he couldnt control and went off
05:04 AM gloops: the peugeots do that Loet, the first sign is a thumping from that area, many dont notice it
05:04 AM Loetmichel: <- cant think of an easy way to lose BOTH weels steering
05:05 AM gloops: i was like wtf when i realised peugeot had RUBBER pulleys
05:05 AM XXCoder: crazy
05:05 AM XXCoder: Loetmichel: honestly thats not strangest way car related uncle deatg
05:05 AM Loetmichel: gloops: as a friend (car dealer) once said: "never buy cars with F. Ford, fiat and french ones!"
05:05 AM XXCoder: other uncle had a car breakdown so he was stuck waiting, and someone come in, seeming to help
05:06 AM XXCoder: well he stabbed uncle in gut and left. no robbery
05:06 AM Loetmichel: ouch
05:06 AM gloops: probably good advice Loet lol, although to be fair i havent had that many bad experiences with fords
05:06 AM gloops: wow XXCoder thats not a normal way to go
05:06 AM XXCoder: always wondered what the heck happened.
05:08 AM XXCoder: only one uncle left, hes been machinist for long time
05:09 AM XXCoder: my uncle and mom is only ones left in family thats older than my bro
05:13 AM gloops: only relative who had a bad motor accident was nephew, smashed his leg and pelvis pretty bad, never worked since
05:13 AM XXCoder: 90s was mayhem for my family
05:14 AM Loetmichel: hihi. in my family i am the one with the accidents
05:15 AM Loetmichel: luckily i dont get hurt BADLY usually
05:15 AM XXCoder: it wasnt just cars mayhem in 90s lol over 20? family members died in that
05:15 AM XXCoder: insane
05:15 AM Loetmichel: <- fell off a big bike (BMW k100) at 140kph as a sozius.
05:16 AM Loetmichel: flew ~50m, sled ~80m... got up and thanked the glide rivets in the racing leather suit
05:16 AM gloops: i gave up with bikes a long time ago, few near misses
05:16 AM Loetmichel: not a single bone damaged
05:16 AM Loetmichel: only black and blue
05:17 AM gloops: times when i thought, jasus another few inches that way or if he had done this or whatever, id be dead now
05:18 AM gloops: Loet sometimes happens like that, you walk away from the spectacular stuff
05:19 AM gloops: then some small thing, car pulls out while youre doing 30mph - you dont wake up for a month, or at all
05:20 AM XXCoder: heh avoided couple very nasty accients with bicycle
05:20 AM XXCoder: one of em I was going downhill very fast, using front brake (no rear brake)
05:20 AM gloops: i had the old LC350, which had a very sharp power band, misjudged a bend with mrs on back, power kicked in fast just at the wrong moment, i did what i had to to stay on the wheels, missed a lamp post by millimetres, that was about it for us and bikes
05:20 AM XXCoder: well it broke off, whupped around on cable and barely missing my head
05:21 AM XXCoder: close enough for my hair to definitely get tagged
05:21 AM XXCoder: and it almost went in between wheel spokes
05:21 AM XXCoder: so yeeah thats triple treat
05:22 AM gloops: been a few fatalities on bicycles round here
05:24 AM XXCoder: fun
05:24 AM XXCoder: gloops: calfornia was pretty bad place for bicycling back then
05:24 AM XXCoder: I once saw car coming down hill, so I moved to left 2 feet to avoid getting hit
05:24 AM XXCoder: well car stopped inches away from me
05:24 AM gloops: i wouldnt like to go out on the main roads on a bicycle these days, its bad enough in a car
05:25 AM XXCoder: wasington state is 50th best state for driving yayyy
05:26 AM Tom_L: heh
05:27 AM XXCoder: its all them damned calfornia drivers
05:27 AM XXCoder: they move here, get SAD and don't know how to drive in rain
05:27 AM XXCoder: then move back there, and get replaced with another calfornian driver
05:28 AM gloops: every morning in the rush here there are several minor bumps on the road into town, just cars shunting one another or clipping one another in the queues - nothing in a car stiff neck maybe, but on a bicycle thats a broken back
05:29 AM Loetmichel: gloops: i am ALWAYS lucky that way
05:29 AM Loetmichel: fell 6 meters from a light rig at a rock concert...(was building it) onto concrete
05:30 AM Loetmichel: laid still, counted all the bones: nothing broken, can still move all limbs. Got up, worked the rest of the day ;)
05:30 AM Loetmichel: had ONE HELL of a concussion though
05:30 AM gloops: lol, you must bounce Loet
05:32 AM Loetmichel: once i got cut by a car on my 50cc... impacted right behind the front wheel well on the drivers side, flew over the car
05:33 AM miss0r: that was YOU !?
05:33 AM Loetmichel: caved in the "A" column about 2", car a writeoff for that (geometry worng)... got up hearing the idiot driver go "my car, my car!"
05:34 AM Loetmichel: ... women on the wheel
05:34 AM miss0r: hehe. I was once cut off like you were
05:35 AM XXCoder: bunch of close calls for me too, the simplest one is that day I was young with uberella. I normally dont use one but had it for some reason
05:35 AM miss0r: the driver made a right turn, and hit the rear wheel of my very very fast moped.. it was originally a 50cc, but I ran a 70cc system. Best guess it, i was doing 80-90km/h. I flew over the car, to the other side of the road and was stopped by a 60km/h speed sign. I walked away with nothing but bruises :)
05:35 AM Loetmichel: fun fact: i caved in the column with my shoulder. had the black and blue bruise to tell the tale...
05:35 AM Loetmichel: ... no bones broken ;)
05:35 AM XXCoder: anyway wind come up and I was dragged back a little when I was crossing street. car passed right by me
05:36 AM miss0r: Loetmichel: Sounds like a nasty crash anyway ;)
05:36 AM Loetmichel: yeah, the bike was totalled, too
05:36 AM Loetmichel: had to replace the whole frame
05:36 AM miss0r: My leg was safed by a metal cigarette case in my pocket, that took the sharp edge of the sign instead of my leg
05:37 AM XXCoder: well night
05:37 AM Loetmichel: miss0r: wasnt THAT nasty. got up, kicked the bike fork back into shape, and drove the rest of the way to work
05:37 AM Loetmichel: ... only about half an hour late for the shift
05:37 AM miss0r: XXCoder: night
05:37 AM gloops: the worst thing to happen to me on a pushbike, id been doing this racer up, got it finished one sunday morning - of course had to have a ride on it, instead of just going round the block, i kept going, on and on 18 miles lol, handlebars came loose at that point - out of socket, no spanners could ride the bike - loooong walk home
05:38 AM miss0r: Loetmichel: I did this when I was in highschool. Only 2 mins walk from school. I walked the rest of the way. The bike was folded in on itself, no way to straighten it
05:38 AM Loetmichel: i LMAO when i heard that the car had no premium insurance and was relatively new though
05:39 AM Loetmichel: got twice the worth of the bike from the insurance, and her car was simply gone. ;)
05:39 AM miss0r: hehe. I didn't hurt the car notably. but I got 3x what I payed for the moped in insuracne :D
05:40 AM Loetmichel: i would really hate that to happen to my moped now though
05:40 AM Loetmichel: its from 1995 and there are not that many spare parts left
05:40 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15295&g2_imageViewsIndex=1
05:40 AM miss0r: And this was a crazy moped: you had to rev the engine 3 or 4 times to get it going, if you just did a hard start, it would throw you off, lifting the front wheel
05:40 AM Loetmichel: on the market
05:41 AM Loetmichel: runs close to 90 as well, original from manufacturer :-)
05:41 AM miss0r: nice
05:41 AM Loetmichel: and 5 shift gearbox on a 50cc to get it going ;)
05:41 AM miss0r: I've done some scary stuff with my mopeds. I even installed a nitrous oxide system on one
05:41 AM Loetmichel: i only did an "electrical turbo" once
05:42 AM miss0r: I've never had a 4-stroke moped, so I never tried that
05:42 AM Loetmichel: removed the carb, fitted a heater blower from a VW bug, refitted the carb ;)
05:42 AM Loetmichel: was fun
05:42 AM miss0r: with a two stroke ? :o
05:42 AM Loetmichel: nope, fourstroke
05:42 AM Loetmichel: but only 50cc
05:43 AM Loetmichel: works with a 2stroke, too
05:43 AM gloops: cant remember the model yahama T? 50, it had hi and lo gear, small lever on side of bike, hand operated, you were supposed to stop to change gear lol, had one of those
05:43 AM Loetmichel: its only about 0,3 bar "steam" though
05:44 AM Loetmichel: ... lasted only ~500km though, then i had a 50cent sized hole in the piston ;)
05:44 AM gloops: it was otherwise automatic change, it always got stuck in the lower gear, made an oscillating while as it approached gear change but took ages to change lol
05:44 AM miss0r: I did this one, there are still pictures online :D https://www.scootergalleri.dk/galleri/38078-yamaha_aerox_solgt
05:45 AM Loetmichel: ah, aeros
05:45 AM Loetmichel: +x
05:45 AM miss0r: yeah, with nitrous :D
05:45 AM Loetmichel: i had a tph for a while
05:45 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=3794&g2_imageViewsIndex=1
05:46 AM Loetmichel: ... drove 42km to work and 42km back each day for 3 years.
05:46 AM Loetmichel: summer and winter
05:46 AM miss0r: I would've ripped that windshield of faster than you could spell it ! :D
05:46 AM miss0r: I see why it is smart, I just don't like the look of it
05:46 AM Loetmichel: it was very useful in the winter
05:47 AM Loetmichel: same for the Alu box on the back
05:47 AM Loetmichel: it fitted 2 boxes 12*1l of soda ;)
05:47 AM miss0r: I also build this monstrocity for a friend of mine back in the day: https://www.scootergalleri.dk/galleri/60156-honda_melody___100ccm_til_salg_
05:48 AM miss0r: Originaly a honda melody. We slapped a 100cc yamaha engine on there :D
05:48 AM Loetmichel: the scooter always was a means to get from a to b
05:48 AM miss0r: For me it was a hobby for 2 years, doing all sorts of stuff
05:50 AM Loetmichel: so it had to be practical, not good locking
05:50 AM Loetmichel: looking
05:50 AM miss0r: Indeed :]
05:50 AM Loetmichel: driving 2 times 1 hour in winter was hard sometimes though
05:50 AM Loetmichel: each day
05:51 AM miss0r: Means you need good clothing
05:51 AM Loetmichel: stopped at a fuel station on half way each winter day
05:51 AM Loetmichel: "one coffee and a hotdog"... to thaw the fingers and knees ;)
05:52 AM miss0r: :D
05:52 AM Loetmichel: jeans, leather jacket, leatehr bike gloves
05:52 AM Loetmichel: basically like on the pic with the Eaglet
05:52 AM Loetmichel: jsut with stuffed gloves
05:53 AM miss0r: I think i'd be wearing one of thoes skeeing suits
05:54 AM * miss0r needs coffee brb
05:59 AM miss0r: Damn, I still have alot of sketches to cad
06:31 AM gloops: another annoying thing with mercs, the thermostat is in a place where it cant be hit with anything
08:06 AM TurBoss: hello
08:07 AM gregcnc_: Taig has released a 5C heastock for their tiny lathe. http://www.taigtools.com/taigturn2000.html
08:34 AM Loetmichel: hmm. statement: 24krpm is a bit much for a 2 flute 6mm tungsten carbide bit in AlMg3... dialing it down to 10k... *calculate: fits* and F1800 fits also. *chewing down 80% of a 600*400*8mm aluminium plate...
08:48 AM gregcnc_: another spaceX launch now
08:49 AM gregcnc_: hah old feed on youtube called live
08:50 AM gregcnc_: watch live , but not live
09:09 AM hazzy: gregcnc 8 of my nieces and nephews from Canada are on vacation and were on the beach in FL last night and saw the launch, they had no idea what is was lol
09:10 AM hazzy: They texted me to make sure everything was OK and it was not a nuclear attack or something!
09:10 AM gregcnc_: but North Korea just had a very good meeting with South
09:11 AM hazzy: For real? I did not know that was possible! thats good
09:12 AM gregcnc_: it was in the news has to be real....
09:14 AM hazzy: that is what the news organizations would like us to think :D
09:14 AM gregcnc_: back to the lathe, turret cleaned up, spindle motor bearings replaced, but now some board seems to be dying.
09:15 AM methods_: yep sounds like typical day at the shop lol
09:16 AM gregcnc_: How high do 24V ciruits generally run in machines. I'm seeing almost 27V, I think
09:17 AM Loetmichel: depends if its an SMPS or a transformer/rectifier/cap deal
09:17 AM gregcnc_: trafo
09:17 AM Loetmichel: the former should be stable to a few 10 mV
09:17 AM methods_: well i've seen mori's that won't take .2 over voltage
09:17 AM methods_: so 27 i would be concerned
09:17 AM Loetmichel: the latter can (depending on line voltage) vary up to 15% or so
09:18 AM hazzy: I have a toroidal with a 24V tap and it is very close to 24V after the rectifier and caps
09:18 AM Loetmichel: hazzy: that is way to low then
09:18 AM methods_: the older american machines seem to be more tolerant of voltage differences
09:19 AM gregcnc_: my power hovers at 250V, the 230-400V is already on the low tap and I'm using the lower tap on the small trafo in the machine
09:19 AM Loetmichel: because 24V AC is nearly 33V after rectifier and caps
09:19 AM methods_: what kind of machine is it?
09:19 AM gregcnc_: Emco
09:19 AM methods_: ah ok
09:19 AM methods_: do you have the schematics for it?
09:20 AM gregcnc_: 400V 3/N/PE, yes been over the schematics
09:20 AM methods_: the schematics might list the tolerance for the voltage there
09:20 AM hazzy: Loetmichel: Sorry, I meant is has a tap for 24V logic power when rectified, a reckon it is about 17V AC
09:20 AM Loetmichel: ah"
09:20 AM Loetmichel: great then
09:21 AM gregcnc_: I may have to add a buck transformer
09:21 AM gregcnc_: oh and still have to look at parameters in the spindle drive
09:33 AM IchGucksLive: hi
09:37 AM IchGucksLive: today ive been told lcnc is near death are we the only ones waving the flaggs
09:37 AM jdh: by whom?
09:38 AM IchGucksLive: the principal of a big university
09:38 AM IchGucksLive: and i said i got 2k klicks a day
09:38 AM jdh: what does he know?
09:38 AM SpeedEvil: What, specifically, is his knowledge of the CNC market?
09:38 AM IchGucksLive: win and a number i guess
09:39 AM IchGucksLive: he is on the Fanuc head dev
09:39 AM IchGucksLive: so Pro not Hobby
09:39 AM SpeedEvil: Ah.
09:39 AM IchGucksLive: but we call us semipro
09:40 AM SpeedEvil: So he's not remotely disinterested then.
09:42 AM gregcnc_: So I guess I'm not using the low tap on the tranformer in the machine. This has taps on the input side marked ±5%. so does +5% means input is high or it changes the output?
09:43 AM Loetmichel: +5% usually means that the input voltage is 5% higher
09:43 AM gregcnc_: thanks
09:44 AM gregcnc_: it should read +5% if it was powered right?
09:57 AM gregcnc_: yes it did
10:59 AM gloops: phew am i glad to be back home lol
11:01 AM gloops: funny when you think your engine is gonna blow up you hear every little sound
11:06 AM Loetmichel: gloops: hihi, i can irate my wife with that pretty well.
11:06 AM Loetmichel: "hey, maybe you should bring your car to the mechanic... that front right wheel bearing sonds a bit scratchy"
11:07 AM gloops: lol, my mrs would just turn the radio up
11:12 AM Loetmichel: thats what she does
11:13 AM Loetmichel: i am the one on the passenger seat that hears such things
11:13 AM Loetmichel: and she is not pleased when i tell her
11:13 AM fragalot: hey
11:21 AM fragalot: miss0r: about to order the epoxy.. all €600 of it :P
11:21 AM fragalot: maybe I should order a small QTY first to see if it's usable >.>
11:23 AM fragalot: CaptHindsight: https://www.mrboat.nl/mrboat-epoxy/mr-boat-epoxy-60-kilo/ <= yes/no?
11:23 AM gloops: DO NOT CLICK fragalot lol
11:23 AM gloops: 600 euros...
11:24 AM sync: that's not too bad for 60kg tho if the epoxy is ok
11:24 AM sync: but 45 mins is not a lot of pot life tbh
11:24 AM fragalot: I couldn't find anything that had a longer pot life
11:24 AM fragalot: (at 20°C)
11:25 AM fragalot: viscosity is higher than what i'd like though
11:34 AM fragalot: alternative could be this one, which promises 50 minutes... https://polyestershoppen.nl/epoxy/universele-epoxyhars-langzaam-5.html
11:34 AM fragalot: much more annoying mix ratio though
11:38 AM fragalot: or this "high temp." version, which sadly has no datasheet, but has a pot life of 120 minutes, and a low viscosity of 200cP: https://polyestershoppen.nl/epoxy/epoxyhars-voor-hoge-temperatuur-80c-268.html
11:45 AM Tom_L: nice breeze today. 60 mph wind gusts
12:00 PM IchGucksLive: hi
12:00 PM fragalot: hey
12:12 PM IchGucksLive: 12meter of 50x10 arived today so hard work tomorrow
12:13 PM fragalot: :D
12:13 PM IchGucksLive: will mill this down
12:13 PM fragalot: i'm busy looking at epoxy suppliers, and vacuum bags/pumps
12:13 PM IchGucksLive: hiwin back and Z mont
12:14 PM gregcnc_: Is there a logical reason to use a value other that motors rated RPM value in VFD setup?
12:15 PM fragalot: gregcnc_: for the rpm reference?
12:15 PM gregcnc_: no, just basic motor specs in the drive
12:16 PM fragalot: not that I can think of, unless if you're using the "under load" numbers?
12:16 PM IchGucksLive: i go for 20k rpm insted of 24k
12:16 PM IchGucksLive: it has a better performence at high rates
12:17 PM gregcnc_: vfd has 1160, vs. the motor 3480
12:17 PM fragalot: that sounds like the motor was replaced by a different model at som epoint
12:17 PM gloops: frequency?
12:17 PM IchGucksLive: gregcnc_: if you know scale modell maker airplane you vcan use there rotary calibrating equipment
12:18 PM gregcnc_: 60hz
12:18 PM gregcnc_: it's works now, but read all the parameters to try to enable braking properly
12:22 PM CaptHindsight: fragalot: don't know, it doesn't translate well
12:26 PM fragalot: CaptHindsight: what information do you need?
12:26 PM fragalot: i'm currently leaning towards the polyestershoppen.nl one as they also carry all of the vacuum bag equiptment
12:27 PM CaptHindsight: fragalot: what is the viscosity when first mixed at room temp?
12:27 PM fragalot: gregcnc_: well the VFD will work fine regardless of the RPM setting anyway if you control it based on Hz rather than RPM.
12:28 PM fragalot: CaptHindsight: I don't see a mixed listed, resin is 800-1100 mPa.s, hardener 100-300
12:29 PM gregcnc_: This VFD is in my Emco lathe. It appears to work OK, though I do see some oscillation at lower RPM. I assume the control actually command the analog signal to the drive.
12:29 PM CaptHindsight: fragalot: since working time is probably the most important factor ...
12:29 PM fragalot: gregcnc_: which is probably scaled from 0-100% of the maximum frequency, so rpm does not come into play
12:30 PM fragalot: CaptHindsight: yeah, they had a "high temperature 80°C" epoxy that had a pot life of 2hrs, but no datasheet, and required a curing process
12:30 PM CaptHindsight: fragalot: ask them about that version, more details
12:30 PM fragalot: will do.
12:31 PM CaptHindsight: fragalot: does it really need the high temp to fully cure?
12:32 PM CaptHindsight: fragalot: unless you pour complete sections baking is not an option
12:32 PM CaptHindsight: and you'll need a large oven
12:33 PM fragalot: it only mentions that it needs to cure to be temperature resistant
12:33 PM CaptHindsight: yeah, that part is not clear
12:33 PM fragalot: I'll ask them advice on what they recommend I use.. Might be faster than asking details on 50 different ones
01:03 PM gloops: hmm, not got linuxcnc computer here
01:03 PM gloops: can i forward a g-code program to a certain line?
01:03 PM gloops: or start from that line
01:04 PM gloops: take something like this http://st.hzcdn.com/simgs/9fd1264b01505f9a_4-1857/traditional-range-hoods-and-vents.jpg
01:05 PM gloops: if cut that from a square block, theres a LOT of roughing out there on the cnc, i can remove quite a lot of that with bandsaw manually very quickly
01:05 PM gloops: but would need to start the g-code closer to the shape, if you see what i mean
01:06 PM fragalot: so start from reduced stock in your cam application?
01:06 PM fragalot: because finding the right line to start from is going to be fun
01:06 PM ves: Cromaglious here
01:07 PM gloops: doesnt have to be bang on the right line, but could get it a lot closer than from square, save some time
01:07 PM gloops: i dont think i can specify a shape to start with, only z height etc
01:07 PM ves: Had a wonderful long weekend at Wild Wild West Steampunk Con at Old Tucson studio outside Tucson, AZ
01:08 PM gloops: excellent ves
01:09 PM gregcnc_: you can restart programs anywhere, but you have to think about exactly what will happen when the next line executes
01:10 PM gloops: im thinking of trying to book a room overlooking whitby harbour for a couple of days over easter, going to sit with a bottle of whisky watching the boats come in lol
01:10 PM gloops: gregcnc so i can start say line 200 - try that, if its still not cutting anything stop, goto line 220
01:11 PM gregcnc_: but I never have any luck with it in Linuxcnc
01:11 PM gloops: ahh
01:11 PM gregcnc_: probably something with my spindle setup
01:12 PM gregcnc_: I usually just post section of the prgram if that's what I need. Like in your case I'd run a roughing path, and only post the finish path.
01:16 PM gloops: hmm yes, once youve found a reasonable starting point in the roughing the preceding code could be deleted - just go with that for repeat jobs
01:55 PM Isleape1 is now known as Isleape
02:14 PM gloops: someone selling some fine work gear from poland https://www.ebay.co.uk/itm/Jacot-tool-watchmakers-lathe-very-good-used-condition-2/282871434725?
02:16 PM gloops: https://www.ebay.co.uk/itm/Original-Steiner-Hahn-Jacot-Tool-watchmakers-lathe-beautiful-condition/282873185289?
02:16 PM gloops: got a few, i guess somewhere has been robbed lol
02:21 PM XXCoder: or died
02:22 PM fragalot: item location poland, yet user claims to be from germany?
02:24 PM gloops: i was in a vintage camera group, this alleged Pole join, started posting photos of his collection, dozens of expensive vintage cameras - which he then decided to sell...lots of members sent money, nobody received a camera
02:25 PM gloops: obviously not trying to say that was anything to do with him being polish
02:26 PM fragalot: bit harder to get away with that on ebay
02:27 PM gloops: he has got good feedback as well, bid with confidence
02:28 PM gloops: https://i.ebayimg.com/images/g/RcoAAOSwpXtanqnf/s-l1600.jpg nice stuff
02:29 PM fragalot: yeah seems to be good stuff, and he's even got quite a few subs which typically means he has good things regularly
02:29 PM fragalot: (or she)
02:29 PM gloops: thats worth £400
02:33 PM XXCoder: closest thing I ever made thats clock is grandfather gear guts in lego.
02:33 PM XXCoder: couldnt make it past past 2 hours
02:33 PM XXCoder: one guy managed 24 hours
02:33 PM gloops: lol
02:34 PM fragalot: my last clock build is more accurate than the digital clocks in our microwave & oven
02:34 PM XXCoder: 100% lego it isn't easy lol
02:34 PM fragalot: which totally has absolutely nothing to do with the italian powergrid causing the european grid to be below 50Hz
02:34 PM fragalot: :P
02:35 PM XXCoder: ac-ac convertor?
02:37 PM fragalot: most wall powered clocks use the line frequency to count time
02:37 PM fragalot: and in /normal/ situations, the power companies guarantee a 50.000Hz average on a daily basis
02:38 PM XXCoder: if I recall usa its 60 Hz
02:38 PM CaptHindsight: if they used gravity for the timing then they would drift less, if you could eliminate friction
02:38 PM XXCoder: capt could go pretty far on removing driction. air bearings, near-perfect fitting gears so on
02:39 PM CaptHindsight: how about those clocks that use RF sent from an atomic clock for sync?
02:39 PM XXCoder: you guys know they are installing 10k years clock now?
02:39 PM XXCoder: been years since I first hear of it.
02:39 PM fragalot: my wristwatch does that - works fine for me
02:39 PM gregcnc_: bezos paid for the 10kyear?
02:39 PM CaptHindsight: XXCoder: I bet it will be obsolete long before
02:40 PM XXCoder: its designed to take account of everything
02:40 PM gregcnc_: except the mountain falling on it?
02:40 PM XXCoder: including orbital changes. it cant takre account of wind/sea affecting earth rotation speed but that averages out
02:40 PM CaptHindsight: I'd say in 1K years from now 20k year or even 50k year clocks will be available for cheap
02:41 PM gregcnc_: oh maybe I'll hold off
02:41 PM CaptHindsight: hehe
02:41 PM XXCoder: it isnt powered by electricity, so unless you mean watches that would last 50k with recharges so on it dont apply lol
02:41 PM XXCoder: http://longnow.org/clock/
02:41 PM fragalot: XXCoder: a 10K watch is impossible
02:41 PM fragalot: history has proven time and time again that the definition of time constantly changes
02:41 PM XXCoder: lol clock I mean :)
02:41 PM fragalot: especially dates are horrible
02:42 PM XXCoder: yeah. there was one feb 30 lol
02:42 PM fragalot: XXCoder: and ther didn't used to be an august 31st either
02:42 PM CaptHindsight: I'd rather have all 30 day months
02:42 PM fragalot: and we skipped a few years
02:42 PM fragalot: and changed the months completely several times
02:42 PM CaptHindsight: then at the end of each year have an extra month to even it out
02:42 PM fragalot: oh and also certain countries don't use 24hr based days
02:42 PM XXCoder: CaptHindsight: I wish too but problem is there is 1/4 day remaining
02:43 PM fragalot: XXCoder: extra holiday for all
02:43 PM fragalot: new new years eve 2.0
02:43 PM XXCoder: lol well it's interesting to see if it even lasts my lifetime
02:44 PM XXCoder: sometimes I wish im immortal so I can see changes across culture and humanity in general for million years or more
02:44 PM fragalot: XXCoder: it should, assuming they don't decide to get rid of daylight savings agian
02:44 PM CaptHindsight: I heard they were moving to all year daylight savings
02:45 PM FinboySlick: fragalot: You're on to something. Maybe resolutions only get to last from New year to the new new year.
02:45 PM fragalot: :D
02:45 PM FinboySlick: Finally a calendar change that makes life much easier.
02:46 PM CaptHindsight: Chicago is right on the eastern border of a time zone...
02:46 PM fragalot: CaptHindsight: time zones are a mess too.
02:46 PM gregcnc_: daylight savings is a pain
02:46 PM methods_: stardate
02:46 PM CaptHindsight: who gets cheater here more? us or the people right across the border in Indiana?
02:46 PM CaptHindsight: cheater/cheated
02:48 PM CaptHindsight: and India is 30 minutes off the most of the rest of us!
02:48 PM CaptHindsight: it's like 3:19 there now
02:49 PM CaptHindsight: and China has 1 time zone where there usually would be 5
02:51 PM XXCoder: lol theres lots strange stuff with timezones
02:54 PM XXCoder: problem with immortality: https://smbc-comics.com/index.php?db=comics&id=2184#comic ;)
03:06 PM gloops: thats a problem with time travel too
03:07 PM XXCoder: sort of. time travel gives a excuse, since person didnt see changes
03:07 PM XXCoder: while immortal person have seen all of history since becoming immortal
03:07 PM gloops: in theory you could travel back in time and kill your own grandfather before he became your grandfather, which is a paradox
03:08 PM XXCoder: negative time travel dont seem possible so far
03:08 PM XXCoder: postive is so easy
03:08 PM gloops: is it?
03:08 PM XXCoder: near-lightspeed is one of methods
03:08 PM XXCoder: freezing, upload to digital mind and save dna for storage so on
03:09 PM gloops: because mass cant attain c
03:09 PM XXCoder: I didn't say AT lightspeed
03:09 PM gloops: or matter anyway
03:09 PM XXCoder: I said near-lightspeed
03:09 PM gloops: highly unlikely we could get anywhere near
03:09 PM XXCoder: sure we can. just takes a while.
03:10 PM XXCoder: ion drive can keep firing for decades
03:10 PM XXCoder: it will take years but it would be very fast evenually.
03:10 PM XXCoder: even better would be photon drive
03:10 PM XXCoder: needs insane amount of power but it can keep firing for decades also,.
03:10 PM fragalot: gloops: the faster you go, the slower time passes for you
03:11 PM gloops: relatively
03:11 PM XXCoder: reverse works also, very heavy gravity also slows time
03:11 PM fragalot: gloops: "for you" :)
03:12 PM gloops: you have to add force to accelerate though XXCoder
03:12 PM gloops: and force = relative mass
03:13 PM XXCoder: high gravity has same time slowing effect also
03:13 PM fragalot: gloops: an ion drive puts out a tiny amount of continuous pushing force
03:13 PM fragalot: i've actually made one myself once.. it's not that difficult small scale
03:13 PM XXCoder: fragalot: photon drive even less, but lasts basically forever (assuming you have power source going forever also)
03:13 PM fragalot: high voltage + tin foil
03:14 PM gloops: thats not going to get any material object to lightspeed
03:15 PM XXCoder: it can
03:15 PM gloops: how?
03:15 PM XXCoder: but we never said actually arrive at C
03:15 PM XXCoder: you keep saying that...
03:15 PM XXCoder: but we never said that.
03:15 PM XXCoder: it tells me youre listening to resond again
03:16 PM gloops: very close to lightspeed? 99%?
03:16 PM fragalot: that depends on how much time you have
03:16 PM fragalot: it's a constant (be it slow) acceleration
03:16 PM gloops: and how much space
03:16 PM fragalot: space is infinite, so we've got that part covered
03:17 PM XXCoder: effect starts at .0001c. just not noticable. its not something that starts to take effect at c only. it increases and at c its at infinite
03:17 PM gloops: well, i dont think space is infinite
03:17 PM XXCoder: fragalot: it may not be infinite
03:17 PM fragalot: XXCoder: or so we think. :P
03:17 PM fragalot: XXCoder: I'm fairly sure the void carries on
03:17 PM fragalot: I doubt the theory that we're just bacteria in a larger life form
03:17 PM XXCoder: I hope theres way to get around c limit.
03:17 PM XXCoder: it takes 10 years at c to nearest star.
03:18 PM gloops: take an object A, a static object, 1kg
03:18 PM XXCoder: at .25c its 40 years
03:18 PM XXCoder: (assuming no accerate and slow down stages)
03:18 PM fragalot: slowing down is for pussies
03:18 PM fragalot: so is steering
03:18 PM gloops: however you decide to push A, you still need the same amount of force to bring it to a given velocity in space
03:19 PM gregcnc_: how do you avoid potholes and road kill going that fast?
03:19 PM XXCoder: one book they had statis that stops time inside field. they was moving at .6c and didnt slow down at arrival. guess how they stopped
03:19 PM fragalot: gregcnc_: I don't think potholes are a problem if you go fast enough?
03:19 PM gloops: gregcnc you only see them behind you
03:19 PM fragalot: XXCoder: but if you're travelling at that speed.. can you still use headlights?
03:19 PM XXCoder: yes.
03:20 PM gloops: you might see a stretched rabbit torso bend around you occasionally
03:20 PM gregcnc_: isn't there all sorts of crap out there even if the distance between is large?
03:20 PM fragalot: just don't forget your towel.
03:20 PM gloops: we dont know 5% of what is out there
03:21 PM gloops: its mainly 'dark matter'
03:21 PM XXCoder: gregcnc_: thats why we would need shield on front.
03:21 PM XXCoder: one book had... interesting idea of using ice
03:21 PM XXCoder: its easy to build and easy to rebuild also
03:22 PM fragalot: drag along asteroids
03:22 PM fragalot: any mass you can come across & pick up
03:22 PM XXCoder: anyway the statis protected ship simply turned on statis and hit an asteroid. that rock become rapidly moving melted rock vapor and ship is stopped
03:23 PM fragalot: did the people on it turn to carbon vapor?
03:23 PM XXCoder: I hope statis fields is possible and inventable lol
03:24 PM gloops: none of it is inventable unfortunately
03:24 PM XXCoder: who knows.
03:24 PM fragalot: that's a big statement. :P
03:24 PM XXCoder: there was people thinking going faster than speed of sound was impossible period
03:24 PM fragalot: XXCoder: flight was impossible too
03:24 PM XXCoder: indeed.
03:24 PM andypugh: I think that they only thought it was impossibe in air.
03:25 PM XXCoder: andypugh: well yes. that era was way before space programs and such
03:25 PM gloops: statistically, there would have been planets capable of evolving intelligent life 2 billion years before earth, in that time if any of this was possible, intelligent species before us would have discovered it
03:25 PM fragalot: turns out that if you buy 60kg of epoxy, and all of the kit required to vacuum bag it properly... the number goes up really quick.
03:25 PM gloops: space would be buzzing with space travellers
03:26 PM XXCoder: unless one of great filters stopped species from getting that smart.
03:26 PM andypugh: The sound barrier may have been first breached by living beings some 150 million years ago. Some paleobiologists report that, based on computer models of their biomechanical capabilities, certain long-tailed dinosaurs such as Apatosaurus and Diplodocus may have possessed the ability to flick their tails at supersonic speeds,
03:26 PM XXCoder: I hope it was something in our past and not something in our future
03:26 PM andypugh: (Wikipedia)
03:26 PM XXCoder: interesting
03:27 PM fragalot: whips are excluded :P
03:27 PM gloops: a mosquito on that tail would also be travelling at mach1
03:28 PM fragalot: a moqsuito on that tail would be dead
03:28 PM fragalot: dead things don't "travel"
03:28 PM gloops: could have been slip-streaming
03:29 PM fragalot: whip-screaming.
03:30 PM XXCoder: "yay" 100th daylight saving time next week
03:30 PM gloops: dark around 6 here atm
03:31 PM gloops: (dark around 4 at shortest day time)
03:33 PM gloops: churchill said it is always darkest before dawn, mao said it is always darkest before total darkness, its all relative
03:34 PM andypugh: It’s generally darkest after dawn too.
03:34 PM andypugh: It’s almost like at’s cyclic.
03:34 PM gloops: quite a bit after dawn
03:37 PM gloops: fragalot what numbers? the price?
03:37 PM fragalot: gloops: all of the numbers, but especially the price, yeah
03:38 PM fragalot: I'll see what they end up suggesting as a total package tomorrow
03:39 PM gloops: whats the vaccum for with this? its an open mold
03:39 PM fragalot: vacuum bag around the mold to get air out, hopefully
03:39 PM fragalot: it's either that, or a very heavy duty vibrating table
03:40 PM fragalot: or, preferably, both
03:40 PM gloops: no prospect of degassing prior
03:40 PM fragalot: don't think that's worth wasting time on
03:40 PM XXCoder: related to dawn thing http://www.optipess.com/2015/02/23/mogwai-meal/
03:41 PM fragalot: or do you mean degas the full mixture prior to dumping it in the mold?
03:41 PM gloops: yes degas the resin
03:42 PM gloops: i dont think theres much time is there
03:42 PM fragalot: the resin separately won't do anything as I still need to mix in the basalt rock
03:42 PM fragalot: but after that's mixed, I could maybe degas that prior to dumping into the mold, which would help
03:43 PM gloops: gas comes from the reaction between resin and catalyst though? air bubbles from mixing the aggregate in is a different issue, although similar consequences
03:43 PM fragalot: and a similar way to solve
03:43 PM fragalot: I don't care where it comes from, as long as it's not in the final product :D
03:44 PM gloops: thats going to be an interesting 10 minutes lol
03:44 PM fragalot: yup xD
03:44 PM fragalot: that's why I don't think it's not a good idea to go cheap on the vacuum pump too
03:46 PM gloops: im sure slipalong tried something epoxy and it didnt go well, someone in here did
03:46 PM gloops: may have vital info
03:47 PM fragalot: miss0r's done one that worked well - still trying to convince him with beer & maybe some good spare ribs to come help
03:47 PM gloops: hes not that far away really
03:48 PM XXCoder: just 10 hours flight eh ;)
03:48 PM fragalot: more like 1.5 hrs
03:50 PM gloops: http://www.freelarge-images.com/wp-content/uploads/2014/11/Map_of_europe.jpg
03:50 PM gloops: its about the entire length of the UK
03:50 PM fragalot: probably less than that even
03:51 PM CaptHindsight: XXCoder: the comic assumes stunted emotional growth and wisdom
03:51 PM gloops: he need a flask and some sandwiches
03:51 PM XXCoder: around typical for optipess yes lol
03:56 PM gloops: well, my little project should be finished for the weekend, might get round to using linuxcnc for once
03:58 PM XXCoder: yayy
04:02 PM gloops: not far off 1 year since first conception, talk about time going slow
04:03 PM fragalot: nah, it's all about biding your time and making informed decisions as you go :P
04:03 PM fragalot: that's my excuse and i'm sticking with it
04:04 PM gloops: first attempt failed, this is the second go at it - but counting that as 1 machine
04:06 PM gloops: run out of things to ask, debate, calculate etc, the next one will be a pretty boring matter of a fact job to build, all the excitement is in the first steps
04:12 PM CaptHindsight: fragalot: I'd pay more attention to the aggregates and allowing yourself enough time to fully coat it all before it sets
04:13 PM fragalot: CaptHindsight: yeah that's going to take time sorting through that stuff :-)
04:13 PM fragalot: i'm still thinking about how to best mix it too
04:13 PM fragalot: current plan is in 12L buckets with everything pre-measured
04:13 PM CaptHindsight: I'd use the lowest viscosity epoxy that sets up slowly
04:15 PM CaptHindsight: sand + epoxy mix added to the larger aggregates
04:15 PM CaptHindsight: sand/granite dust
04:16 PM fragalot: good tip
04:16 PM CaptHindsight: the main problem most have is ending up with voids
04:16 PM gloops: add gravel to liquid?
04:16 PM gloops: not liquid to gravel
04:17 PM fragalot: CaptHindsight: Aye - that's why I'm looking into vacuum bag packages, part of me wonders if it's worth vacuuming the individual mixes rather than the entire mold to get more air out?
04:18 PM CaptHindsight: at least 2 people, one keeping the mix going and the other filling the forms
04:18 PM CaptHindsight: you won't have many bubbles with 200 cPs epoxy at room temp
04:19 PM CaptHindsight: >1000 cPs is another story
04:20 PM CaptHindsight: higher viscosity epoxy is generally tougher than lower
04:20 PM fragalot: can't have everything
04:20 PM CaptHindsight: higher temp lowers viscosity but speeds curing
04:20 PM fragalot: the trade-off there isn't fair at all though
04:21 PM fragalot: lower temp slows it down a bit, but the viscosity typically skyrockets
04:23 PM gloops: 600kg - say 1kg = 1 litre, thats some stuff to mix, would need a cement mixer or something
04:23 PM gloops: a bucket is what 10 litres
04:24 PM gloops: 60 buckets
04:24 PM fragalot: gloops: it's 2 separate molds
04:24 PM fragalot: first one is "only" 30 buckets :P
04:24 PM fragalot: the other is for another day
04:24 PM gloops: well 30 buckets then
04:25 PM gloops: its going to take 5 minutes a bucket? to measure and add the stuff, then mix it
04:25 PM CaptHindsight: 20 L pail will weigh ~22Kg full of epoxy
04:25 PM fragalot: 60 buckets total of dry aggregate, 30 measuring cups of epoxy, 30 of hardener
04:25 PM fragalot: all pre-measured
04:26 PM fragalot: buckets are cheap - all I need to do is find somewhere to put it all xD
04:26 PM fragalot: actually there's no way this is 30 full buckets
04:26 PM gloops: a bag of sand is 25kg
04:28 PM CaptHindsight: loose sand ~1.4 Kg/L
04:28 PM gloops: im thinking the standard issue black buckets we get here, i think theyre 10l, might be 15
04:28 PM fragalot: yup
04:28 PM gloops: bigger buckets = harder to mix
04:28 PM fragalot: can get those super cheap here
04:29 PM fragalot: it's like €1 for a heavy duty rubber bucket
04:29 PM gloops: mechanical mixing adds air
04:31 PM CaptHindsight: fragalot: whats the plan for forms?
04:32 PM fragalot: CaptHindsight: made the form out of plywood that's been finished with body filler, 2 layers of PU, and 4 layers of carnauba wax
04:33 PM fragalot: steel inserts, 10cm long M10 bolts every 4cm
04:37 PM fragalot: I'm off - cya tomorrow :-)
04:37 PM fragalot: thanks for the tips
04:42 PM JT-Shop: dang it's windy
04:49 PM Deejay: gn8
04:53 PM CaptHindsight: we got wet snow again
04:54 PM gloops: these look pretty lethal https://www.ebay.co.uk/itm/High-Strength-Steel-Wire-Saw-Adventure-Scroll-String-Saws-For-Camping-Hunting-W3/292468560906?
04:55 PM CaptHindsight: gloops: did your snow stick around?
04:56 PM Jymmm: gloops: P I T A to use
04:57 PM CaptHindsight: Jymmm: it's easy, just hand each end to another person
04:58 PM gloops: no snow has gone here
04:58 PM andypugh: I have used those string saws. They are reasonably effective.
04:58 PM gloops: compact to carry around
04:59 PM gloops: an old weather sage on TV, goes by the trees and birds and so on says we will get a repeat of last week starting march 17th - he has been reasonably accurate this year apparently
05:00 PM Jymmm: gloops: This is EXCELLENT and much better... http://www.fiskars.ca/Products/Yard-and-Garden/Pruning-Saws-and-Tools/Power-Tooth-R-Sliding-Pruning-Saw
05:00 PM CaptHindsight: https://youtu.be/AmyJuhMbueU?t=2m1s use wet stick to makes works betters
05:01 PM gloops: i have got something like that Jymmm, tbh i wasnt looking for saws it just came up as a suggestion on something else
05:02 PM Jymmm: gloops: I get you, just trying to steer you away from that and the grief it brings =)
05:03 PM Jymmm: CaptHindsight: Shit, and only a 2" branch, screw that!
05:03 PM CaptHindsight: Jymmm: any tips for opening coconuts?
05:03 PM Jymmm: CaptHindsight: I have a folding box saw I keep in the car all the time, goes thru a 5" tree in seconds.
05:04 PM Jymmm: CaptHindsight: hacksaw or machette
05:04 PM Jymmm: or any heavy knife
05:04 PM Jymmm: that oyu dont care about =)
05:06 PM gloops: bandsaw for coconut
05:06 PM Jymmm: CaptHindsight: what gloops said!!!
05:07 PM CaptHindsight: https://youtu.be/RIGpL-M61IE?t=2m15s vs box saw
05:07 PM Jymmm: CaptHindsight: IF you dont care about the milk, then I'd suggest a 3rd floor stress analysis test =)
05:08 PM CaptHindsight: can elephant open coconut without losing the milk?
05:08 PM gloops: you could cut coconut segments with bandsaw, lot easier to nibble
05:13 PM CaptHindsight: most fruits and vegetables are no match for a shop full of tools
05:13 PM CaptHindsight: or herd of elephants
05:14 PM Jymmm: elephants make beer too
05:14 PM CaptHindsight: if you had to head off into the jungle with only one tool, what would you pick?
05:16 PM CaptHindsight: hand operated tool, no electrical cord or combustion engine
05:16 PM Jymmm: JUNGLE specifically?
05:16 PM DaViruz: foot pedal cranked lathe!
05:16 PM CaptHindsight: jungle/rain forest
05:16 PM Jymmm: or just BFE?
05:17 PM Jymmm: desert? mountains?
05:17 PM gloops: tin opener?
05:17 PM CaptHindsight: no dessert, mountains are possible
05:17 PM gloops: would have to be either knife or axe seriously
05:18 PM Jymmm: knife with a ferocium handle =)
05:18 PM gloops: although you could make an axe with a knife, so knife
05:21 PM CaptHindsight: how long would it take to make a knife from only ore if you had ample food and water and a moderate forest nearby?
05:22 PM Jymmm: CaptHindsight: Ask the indians =)
05:23 PM CaptHindsight: Jymmm: well they didn't know how to refine
05:24 PM gloops: if you knew how to do it, not that long
05:25 PM gloops: to conceive of doing it, and learn how - thousands of years
05:27 PM gloops: first you need to make charcoal, or more important - find coal
05:27 PM gloops: then some bellows
05:28 PM CaptHindsight: if raw materials were available from outcroppings
05:28 PM CaptHindsight: no extensive digging required
05:30 PM CaptHindsight: " Inuit peoples who used iron from meteorites to make blades"
05:33 PM gloops: once you have some iron youre away, damascus techniques, beat carbon into it etc
05:35 PM Jymmm: My luck, I'd find cesuim-137 ore =)
05:35 PM gloops: may as well just use stone
05:36 PM gloops: for defence, if a sharp flint axe head hits you round the head the results are just the same as if it had been an iron axe
05:43 PM JT-Shop: magine you're a deer. You're prancing along, you get thirsty, you spot a little brook, you put your little deer lips down to the cool clear water... BAM! A fuckin bullet rips off part of your head! Your brains are laying on the ground in little bloody pieces! Now I ask ya. Would you give a fuck what kind of pants the son of a bitch who shot you was wearing?
05:45 PM gloops: if his pants had been bright yellow i would have seen him coming
05:45 PM gregcnc_: would be nice if they were some ecologically sustainable fiber
05:52 PM andypugh: JT-Shop: I had you down as the sort of chap who would shoot deer. (Mainly because you are Americn) Suddently I am not so sure.
05:53 PM JT-Shop: I have shot one in my life... I feed them everyday now
05:53 PM JT-Shop: I'm not much for killing...
05:54 PM andypugh: Yeah, I got that impression from the deer’s eye view of the world.
05:54 PM jdh: killing large mammals is rather messy and altogether unpleasant
05:54 PM andypugh: What type do you get round there?
05:54 PM JT-Shop: it's my favorite quote from the movie My Cousin Vinny
05:55 PM JT-Shop: we get medium sized deer here, the more north you go the bigger they get
05:55 PM jdh: most of .us is overrun with whitetail deer. they are murderous animals who kill many people each year
05:55 PM JT-Shop: lol
05:55 PM gregcnc_: 200+ annually
05:56 PM JT-Shop: hmm chickens are going to roost... time to lock the run up
05:56 PM andypugh: We have some tiny feral introduced ones (rather cute) https://www.bds.org.uk/index.php/advice-education/species/muntjac-deer
05:57 PM sync: pocket deers
05:57 PM jdh: they are kind of cute.
05:57 PM JT-Shop: Missouri has a growing elk herd now
05:57 PM jdh: so are white tail deer until they come through your windshield
05:57 PM sync: they have to hunt the deer in germany or otherwise they become a pest
05:57 PM CaptHindsight: how many via car accidents vs antler impalement?
05:57 PM gloops: theyre a pest here now
05:58 PM gloops: deer also spread a terrible parasite - deer worm, or brain worm
05:58 PM CaptHindsight: they tend to stare at us when out walking
05:58 PM pcw_mesa: Muntjac deer have big canine teeth
05:59 PM JT-Shop: more deaths from hitting a moose than a medium deer
05:59 PM CaptHindsight: they seem very judgmental
05:59 PM andypugh: pcw_home: Vampire deer?
05:59 PM andypugh: As cute as Vampire Squrrels?
05:59 PM pcw_mesa: Maybe so
05:59 PM andypugh: (Which do exist)
06:00 PM gloops: this worm lives in the gut for most of the cycle, but then migrates to the nervous system and brain, really a terrible death, very quickly advancing paralysis - until zombified, then die
06:00 PM CaptHindsight: they don't seem to be very alert around here, I often stumble across them only meters (yards) away from the trails
06:02 PM CaptHindsight: lots of coyotes around here as well
06:11 PM andypugh: Yeah, buy Coyotes only hunt Roadrunners, ineffectively. I have seen it on documentaries on the TV
06:11 PM CaptHindsight: ACME
06:12 PM andypugh: I was delighted on my trip to Arizona to see both a Coyoye, a roadrunner and a tumbleweed.
06:15 PM CaptHindsight: I'll be happy to send you some
06:15 PM CaptHindsight: if they allow the import
06:17 PM CaptHindsight: another thing to blame on the Russians
06:17 PM CaptHindsight: https://www.usu.edu/weeds/plant_species/weedspecies/russianthis.html
06:18 PM andypugh: I got lost in Wikipedia. Now I am looking at Fennec foxes. They are very cute.
06:21 PM sync: yes they are
06:28 PM CaptHindsight: how well do donuts keep bagged in the freezer?
06:37 PM Jymmm: CaptHindsight: Well, but will dry out if too long
06:38 PM CaptHindsight: texture tends to get lost with frozen bakery items
06:51 PM Jymmm: CaptHindsight: mor elike freezer burn
07:00 PM Jymmm: JT-Shop: jthornton https://youtu.be/w-n59D6RQNQ?t=224
07:00 PM Jymmm: JT-Shop: PTO dump trailer ^^^^^^^^^
07:10 PM Jymmm: Saw for gloops https://youtu.be/w-n59D6RQNQ?t=693
08:20 PM gregcnc_: anyone familiar with Lenze VFD setup?
11:37 PM fragalot: hi
11:54 PM hazzy: hello fragalot
11:54 PM hazzy: goodnight fragalot
11:54 PM fragalot: xD bye
11:55 PM hazzy: :)
