12:11 AM XXCoder: reading about presidental coin.
12:13 AM XXCoder: lol
12:13 AM XXCoder: https://img.washingtonpost.com/rf/image_700w/2010-2019/WashingtonPost/2017/12/22/National-Politics/Images/COIN007.JPG
12:15 AM XXCoder: compared with previous president https://img.washingtonpost.com/rf/image_800w/2010-2019/WashingtonPost/2017/12/22/National-Politics/Images/COIN008.JPG?uuid=kfJpUOZ5EeeSeucurB5ztg
01:56 AM gloops: clever ideas but this kid is a health and safety disaster https://www.youtube.com/watch?v=lSoWxG30rb0
01:57 AM gloops: melting metal on a wobbly plant stand wearing pumps and a t shirt
02:03 AM archivist: they never learn, just look at the channel logs for Loetmichel stabbing himself :)
02:03 AM gloops: how did he stab himself?
02:04 AM archivist: which time
02:05 AM gloops: ive watched a few of that kids videos, he does some dangerous stuff, handling a big crucible full with 2 pair of small pliers, had brass erupting all over - only got sunglasses on lol
02:05 AM gloops: he has got the basic principles right though im going to try something similar
02:10 AM Deejay: moin
02:36 AM gloops: well, more drilling, ran out of 4mm plate only 10mm left - hard work
02:43 AM Contract_Pilot-A: Sup...
02:55 AM gloops: machine making fatigue has set in
04:09 AM gloops: no Ichs today, or yesterday?
04:33 AM archivist: started on another window, effin battery gone flat before the frame is all cut
04:34 AM jthornton: morning
04:35 AM gloops: cant beat a new sandvik saw, medium cut
04:41 AM gloops: ive got one screw mount tacked up, with a blob of weld on a linear rail lol
04:41 AM archivist: saving new saws from frame cutting, dont want to hit the cement
04:41 AM archivist: oops
04:42 AM gloops: will polish off but will do that later, properly
04:49 AM Loetmichel: gloops: i slipped with a hand deburr tool and cut my thumb muscle. nothing serious... -> (caution, some blood) http://www.cyrom.org/palbum/main.php?g2_itemId=16188&g2_imageViewsIndex=1
04:49 AM Loetmichel: ... i htink thats what archivist was referring to
04:51 AM archivist: accident prone or careless :)
04:51 AM Loetmichel: the latter i think
04:52 AM Loetmichel: or should i say: a bit clumsy sometimes
04:52 AM gloops: jolly good
04:53 AM archivist: BBC says we should look out for clumsy and forgetful at xmas http://www.bbc.co.uk/news/health-42456853
04:53 AM gloops: have split upper thub with chisel a few times, tend not to do it so much when you find out how deep a chisel cuts
04:55 AM Loetmichel: I managed to put an 1/8" tungsten carbide 2 flute mill bit thru the thumb bone... fun stuff. at 24krpm in the mini mill its thru SO fast you dont even notice. you just wonder why your hand is locked to the machine... -> http://www.cyrom.org/palbum/main.php?g2_itemId=2958
04:57 AM Loetmichel: ... thats what you get when you are to lazy to turn off the spindle while changing workpieces ;)
05:25 AM miss0r: Why does santa go 'ho ho ho' ? because he has a list that shows where all the naughty girls live... :]
05:59 AM nallar is now known as Ross
07:17 AM gloops: seriously doubting 16mm screws are good to 1500 rpm
07:19 AM archivist: once there is a middle support (the nut) they will be better
07:20 AM gloops: one is on, bit bendy
07:21 AM gloops: got to consider at the far reaches the majority of the screw is unsupported
07:21 AM gloops: ahh well, soon know hopefully, calculator says 1750 rpm, i reckon 1000
07:22 AM gloops: requires no turning at all, light thumb and finger brings the gantry staright along so far
07:23 AM archivist: just got to the difficult bit for an upstairs window and only me, have to hold and drill
07:25 AM gloops: few wooden wedges can be helpful, and a bit of foam to hold it
07:25 AM gloops: and make sure its screwed to the cill - easily slip off it
07:27 AM archivist: full opener so have to have it open, bit of string to something indoors
07:28 AM gloops: or take opener off - can be awkward to put back though single handed
07:29 AM archivist: when at the window company I went out on service calls to help when fixing hinges
07:31 AM gloops: will go back in the same screw holes, depends how big opener is though, you should be a dab hand then heh
07:32 AM gloops: any old wooden plugs in the brickwork are good to get a holding screw in, just a wood screw,
07:34 AM archivist: this particular window I cannot get a ladder too properly either
07:34 AM XXCoder: build a build platform?
07:35 AM gloops: seal from inside - let the silicone set before glazing, or it will be all over with the hammering
07:35 AM gloops: lot of new windows though you can press the beads in with hands
07:37 AM archivist: I silicon after glazing
07:38 AM gloops: it is the best way, but if you cant get a ladder to it, you can reach out before the glass goes in to seal it up
07:38 AM archivist: these are tight beads need a good wallop with the plastic
07:39 AM archivist: ladder is one side so can silicon
07:39 AM archivist: sammich time though
07:39 AM gloops: still some profiles with awkward beads, a lot moved to more fitter friendly designs - saves a lot of broken glass and snagging with ill fitted beads
07:41 AM gloops: truemans sell a profile with nightmare beading, you get the glass packs wrong its a definite cracked unit, difficult to explain to anyone too, you realise whats happening after youve broke a few
07:44 AM archivist: I am using synseal seem ok
07:45 AM gloops: have used that, cant remember what its like now
07:47 AM archivist: current stuff is internal bead with a single engagement part, unlike the impossible hook types
07:50 AM archivist: I hate the external beaded types with double sided sponge tape
07:51 AM gloops: yeah, where the pressure goes through the rubber, the ones that have 2 tracks and press in toward the glass, if you get a pack behind the front sheet of glass and the bead pushes it - crack
07:52 AM gloops: the tape is probably better than back gaskets security wise
08:14 AM enleth: dammit, it's weird to see people in a civilized country discuss problems long solved with preassembled window units
08:24 AM malcom2073: If money is no object, life gets much easier :)
08:31 AM enleth: money is no object if absolutely everyone on the continent makes and uses preassembled windows
08:31 AM enleth: economy of scale and all that
08:55 AM gloops: pre-assembled?
08:57 AM archivist: replacements have to be made to fit existing holes
08:57 AM archivist: there is effectively no standard window hole
08:58 AM gloops: seen two types in new build, one that snaps into a plastic cavity liner, another with clips screwed to the wall, most still use screws lol
08:59 AM archivist: the ones I am taking out were obviously factory made to a 1960 "standard"
09:00 AM gloops: any lintels above them?
09:01 AM archivist: yes but not correctly fitted to modern building regs
09:02 AM gloops: 150mm on the brickwork
09:04 AM gloops: well thats me done for today, second x screw ready to fit, its that time to go shopping...
09:04 AM archivist: 0" all the weight on the wood frame!
09:05 AM gloops: lol
09:05 AM gloops: a lot had none anyway they built straight on the window frame
09:06 AM archivist: all this lintel did was spread the load to the outers, effin silly
09:07 AM archivist: all I have looked at have dropped a bit
09:07 AM gloops: would go steady under those - broken neck time of that comes down
09:08 AM gloops: no arch or anything above?
09:08 AM archivist: arch....not in 1960
09:09 AM gloops: maybe some steel in the brick joint?
09:09 AM archivist: will give most of the frames a bit of framefix along the top
09:10 AM gloops: one round corner from me had safestyle, gable end is collapsing ill try and get a pic sometime, ready for going any time, told her shes totally not concerned lol
09:12 AM archivist: mate had some rough safestyle work, needed quite a lot of remedial work
09:14 AM gloops: from the road the job doesnt look bad, teak coloured windows very nice, but arch has slipped - triangle of brickwork 6 foot accross has parted and come down an inch at least
09:43 AM enleth: archivist: you don't need standard sizes for pre-assembled factory-made windows - there are standard sizes you'll get right there from the factory warehouse, but a custom size is going to be priced *exactly* the same way (per cm of width/height or per square cm of window area) as a standard size
09:44 AM enleth: you'll just have to wait a day or two for a custom to be assembled
09:46 AM gloops: Junckers been at the xmas sherry already lol https://www.youtube.com/watch?v=MY_RgHjg3Bw
09:46 AM enleth: pretty much all of the EU does it that way and the only real exceptions are windows made to imitate antique designs for historic landmarks that are not allowed to look too modern, and some really weird and non-standard window shapes/sizes
09:47 AM enleth: you just set the frame into the wall by whichever means are appropriate for a given wall and window size and plop the window itself on the hinges, done
09:48 AM gloops: we have building regs here enleth
09:49 AM enleth: you say it as if there were none elsewhere
09:50 AM gloops: the specs for our windows have to conform with the highest standards, for thermal insulation properties, and so on
09:50 AM enleth: again, you say it as if they didn't elsewhere
09:51 AM gloops: supposing you dont want one big opener
09:51 AM enleth: what
09:52 AM gregcnc: for new construction right?
09:52 AM gloops: youre saying you fit a sub frame, then one big sash on hinges
09:52 AM enleth: did I?
09:52 AM gloops: looks like it yeah
09:53 AM enleth: if you order a single frame that is divided into several separately opened windows, you'll get that from the factory too
09:53 AM enleth: for the cost of three more hinge/handle sets and a little more PVC/wooden profile
09:54 AM enleth: or however much you need
09:55 AM enleth: the only real downside of preassembled units is the weight, if you need particularily big windows - I assume it might be a tad easier to fit a really huge and heavy one if you handle the glass separately
09:56 AM gloops: well ive got to go bbl
09:56 AM enleth: although I guess you *could* ask the factory to deliver the window with the glass panels and the retaining frame separate, I've never done that
09:56 AM enleth: it just snaps together
10:00 AM archivist: the frames here are welded
10:03 AM enleth: but why do you need to fit the glass on-site?
10:04 AM archivist: because the fitting screws are in the glass recess
10:05 AM archivist: nothing shows inside or out
10:05 AM enleth: ugh
10:05 AM enleth: sounds like a lot of fun if the frame, not being held square by the glass, warps even a little when pulled by the screws
10:05 AM archivist: also a lighter and safer to fit system, a lot less weight
10:06 AM archivist: there is clearance
10:06 AM jym: Anyone use gDrive on linux (or want to)?
10:09 AM jdh: no.
10:10 AM * jym just uploaded a 400MB file TO gdrive in 20 seconds =)
10:12 AM Tom_L: kinda 2000's tech there ehh?
10:13 AM jym: tachoknight: as in year 2K ?
10:13 AM jym: err Tom_L
10:14 AM jym: Tom_L: Seeing that I do NOT have google fiber...
10:14 AM Tom_L: that's like giving google permission to invade your privacy
10:15 AM jym: Tom_L: Oh no, it's all shell access to gDrive via the API
10:16 AM jym: Tom_L: But I know what you mean, thus my reluctance to install gSync
10:16 AM jym: Tom_L: ...same goes for dropbox
10:17 AM jym: Tom_L: But check it out, works great... https://www.howtoforge.com/tutorial/how-to-access-google-drive-from-linux-gdrive/
10:18 AM jym: Tom_L: I installed it on my hosting account and uplaoded files from there
10:50 AM gregcnc_: shipping is crazy fast right now. I had something show up today by fedex originally scheduled for the 28th.
10:51 AM gregcnc_: even the mcmaster order I placed last night is delivering today
10:55 AM JT-Shop: turns out the 308 can do thread milling and has mdi
11:02 AM gregcnc_: never used MDI?
11:03 AM JT-Shop: not on the DX32 control
11:04 AM JT-Shop: I usually let OneCNC create my G code
11:04 AM gregcnc_: not even when touching off tools?
11:05 AM jym: JT-Shop: How much is OneCNC ?
11:05 AM JT-Shop: too much IIRC
11:06 AM Tom_L: so no conversion in site for the 308?
11:06 AM gregcnc_: 4kUSD?
11:06 AM gregcnc_: base
11:06 AM jym: gregcnc_: thanks
11:07 AM Tom_L: JT-Shop, how many HP is the 308 spindle?
11:08 AM Tom_L: just wondering how well it handles those larger taps
11:11 AM JT-Shop: 7.5hp
11:11 AM JT-Shop: it does well up to 5/8-11
11:11 AM JT-Shop: I might be running the spindle too slow
11:13 AM gregcnc_: does the manual have a hp-tq curve for the spindle?
11:13 AM roycroft: shipping has mostly been really fast for me, with a notabl execption
11:14 AM roycroft: mcmaster orders used to take two days out of reno, now they're taking four days out of reno
11:14 AM roycroft: everything else is arriving wicked fast
11:14 AM roycroft: oh, except for that vfd remote panel from china, that seems to be going from china to the us via mars
11:16 AM roycroft: and i will actually need that soon - i'm starting to build my router table today
11:17 AM JT-Shop: gregcnc_: I have to look after while
12:20 PM Contract_Pilot-A: Mornin
12:41 PM JT-Shop: gregcnc_: no mention of hp torque curve in the manual
12:42 PM JT-Shop: Tom_L: I'd have to replace the spindle motor :( it's special one
12:50 PM Contract_Pilot-A: maybe next week my head will be clear to sort the settings and wiring out for My VFD
12:51 PM Contract_Pilot-A: Just hope i can use my WJ200 and hope i do not have to go to an Emerson SK series
12:53 PM JT-Shop: interesting you thread mill from the bottom up
12:56 PM gregcnc_: it can be done a variety of ways, but if you want to climb mill a right hand internal thread, then yes
12:58 PM rene-dev: unleyy you have a left hand cutter ;D
12:58 PM rene-dev: unless
01:09 PM JT-Shop: I've never programmed a thread mill so I'm looking for info
01:10 PM JT-Shop: I saw one example of doing a 180 degree arc to cut depth then 360 then 180 out
01:10 PM JT-Shop: then move to center and z out
01:16 PM gregcnc_: I followed the Smid book, it shows g1 from center and 90° lead in/out. This depends if you use rad comp and can apply on an arc move or if you need a G1.
01:33 PM Contract_Pilot-A: Have the NPN N/C prox on the way for the lathe.
01:43 PM gregcnc_: enleth that microtik has a pile of options but I must be dumb
02:13 PM enleth: gregcnc_: the very first screen should be "quick setup" or something to the tune
02:13 PM gregcnc_: yeah
02:13 PM enleth: you got the mAP lite, right?
02:14 PM gregcnc_: yes
02:14 PM enleth: there's a bridge mode checkbox or selector somewhere in the top right area of that screen, but before you toggle it and click apply, you also want to remove one firewall rule
02:15 PM enleth: I'm not at home right now but when I get back, I'll make a screenshot of the firewall settings page
02:16 PM gregcnc_: just change to accept?
02:18 PM enleth: yes, there's arule that drops incoming new connections on the wired interface
02:18 PM enleth: you want to remove it or change to accept to be able to access the admin panel from the wired side
02:19 PM enleth: otherwise the bridge mode checkbox will do all you need
02:22 PM SpeedEvil: https://i.imgur.com/02kKtXa.png Sub prop porn
03:00 PM gregcnc_: enleth I did it the hard way https://skagitsignal.com/wireless-ethernet-bridge-connect-legacy-devices-boost-smart-appliances/
04:04 PM gloops: screw propellers kill eels
04:09 PM gloops: more good news from the UK, we are the fastest growing economy on the planet!
04:11 PM gloops: the government should give archivist 10 billion £s to buy all the old lathes and mills on ebay and cnc them
04:15 PM MrHindsight: it's ok my hovercraft is full of them
04:19 PM MrHindsight is now known as CaptHindsight
04:27 PM Deejay: gn8
05:02 PM methods_ is now known as _methods
05:28 PM Tom_L: JT-Shop, as much as thread mills are, i'd practice on some wax the first time
07:00 PM ziper: has anyone here participated in a makerspace or anything similar
07:00 PM XXCoder: mkerspaces is expensive membership
07:02 PM ziper: yeah
07:03 PM ziper: this one is 110 a month and doesnt even seem to have a metal lathe or mill
07:03 PM ziper: i'm better off creeping in garages and trying to befriend some old guy
07:05 PM XXCoder: orrr
07:05 PM XXCoder: go to college
07:05 PM ziper: i did
07:05 PM XXCoder: take couple classes, some have elect classes you can repeatively take
07:05 PM XXCoder: basically cheap access to machines
07:07 PM ziper: last time i checked my community college had a bunch of neat classes on the catalog that were never actually available
07:07 PM ziper: i'll look again
07:07 PM enleth: ziper: look for hackerspaces, usually more non-profit oriented and sometimes more likely to have heavy machinery just for the heck of it
07:08 PM XXCoder: look for elective ones, usually not graded and you can do whatever
07:08 PM XXCoder: clark college for one has em
07:29 PM ziper: nope as far as i can tell they have absolutely nothing even approaching that
07:33 PM XXCoder: can audit I guess.
07:33 PM XXCoder: make your stuff and dont care about grades lol
07:34 PM ziper: they don't even offer them as regular classes
07:34 PM XXCoder: so what you want to do? lathe mill what
07:36 PM Connor: okay, So, this VFD I have has a E-Stop sig.. However, it looks as if it's a NO circuit and to get a stop command, I have to close it.. Isn't that backwards?
07:37 PM Connor: I might as well run it in series with the FWD / -- / REV switch
07:37 PM ziper: boat parts, pipe fittings, shafts, engines, fishing reels, bongs
07:37 PM Connor: Also, trying to figure out if the RUN enable has to be toggled for JOG to work..
07:38 PM Connor: these manuals leave a heck of allot to be desired..
07:38 PM XXCoder: whats sad if you find cnc mill for say $2000 and fix it and it works fine
07:38 PM XXCoder: its cheaper than 2 years membership
07:38 PM ziper: yeah
10:00 PM Tom_shop: got a little bit done tonight: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Assembly_Up.jpg http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Assembly_Down.jpg
10:20 PM XXCoder: Tom_shop: yo
10:21 PM XXCoder: is that 4th axis rotatry case on spindle assembly? or is it somethinbg else
10:42 PM Tom_L: it's the Z overhang for the spindle mount
10:42 PM XXCoder: oh so spindle will be mounted on that flat side
10:42 PM Tom_L: yeah
10:43 PM Tom_L: and the X table will go on the base slides
10:43 PM Tom_L: once they're installed
10:43 PM XXCoder: im not sure hpow it would work
10:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
10:44 PM XXCoder: the moubnted ballscrew is Z correct?
10:44 PM XXCoder: ahh ok
10:53 PM Crom: Hmmm, been sitting here trying to figure out an automagical backlash detection/measurement method
10:54 PM XXCoder: got a dial indictor?
10:55 PM XXCoder: you could use that to detect some backlash
10:59 PM Crom: been thinking home the machine, then go to another location with a setup with a wiper to ground the spindle shaft, then advance into a edge of something to complete a circuit, then reverse to circuit open, # of steps is backlash. setup the measurement station to guage X- X+ Y- Y+ Z- Z+
11:06 PM `Wolf: build a renishaw
11:10 PM `Wolf: figured out how to cnc/ball screw my knee mill very quickly… https://i.imgur.com/5Yugmpp.jpg just need clamps… =)
11:12 PM Crom: Great picture... I need to take my base over to a friends HF 33686 RF-31 and mill it for the increased Y
11:14 PM `Wolf: i needed some place to put it that wasn’t the floor because screw lifting that thing after I set it down that far
11:32 PM `Wolf: that x2 conversion is a old project of mine, about time I try to finish it lol
11:52 PM Crom: What table is on that X2 base?
11:53 PM `Wolf: LMS x1 extended x/y kit
11:56 PM `Wolf: https://littlemachineshop.com/products/product_view.php?ProductID=3860
11:56 PM `Wolf: the solid x2 column bolts direct to it
11:58 PM `Wolf: my x2 is a very odd mix of parts lol
