08:55 AM rue_mohr: --
09:13 AM furrywolf: 52F in here today... might be time to get some kereosene for winter.
09:20 AM rue_mohr: 52F is enough to power an LED for a while...
09:20 AM rue_mohr: oooh, wait, silly temperature units...
09:20 AM rue_mohr: cmon, man, lets use kelvin
09:22 AM rue_mohr: https://www.electronics-tutorials.ws/waveforms/tim12.gif
09:22 AM rue_mohr: I'm not of a lot of brain power right now, but I'm SURE the output pulse polarity is wrong
12:59 PM Tom_L: https://lulz.com/linux-devs-threaten-killswitch-coc-controversy-1252/
03:49 PM zhanx: not a real fan of catering to a very very small minority due to the fact they are vocal
06:47 PM zhanx: my new monitor is 55" and was on the side of the road, works just fine
07:03 PM rue_mohr: too much social bull for me
07:03 PM rue_mohr: but I'll D/L some of the newer kernel source before its too late
07:06 PM zhanx: if they pull this, big business will take over kernel dev
07:09 PM Tom_L: gates specifically
07:31 PM rue_shop4: microsoft doesn't want to do os stuff, they said so like 6 years ago
07:49 PM Tom_L: so why do they advertize running linux under windows 10?
09:19 PM Tom_L: rue_mohr
09:19 PM Tom_L: is the pitch geometry the same on metric threads as equivalent size american threads?
09:20 PM Tom_L: is the thread angle the same i guess is what i'm trying to figure out
09:22 PM rue_shop4: 60 degree, yea
09:23 PM Tom_itx: https://www.ebay.com/itm/M5-45-1-00mm-SINGLE-PITCH-THREAD-MILL-BRAND-NEW-TiALN-COATED/351020027874?hash=item51ba6c8fe2:g:udQAAOSwC~1a9lVy

09:23 PM Tom_L: those 2 look to be identical
09:24 PM Tom_L: other than the TPI designation
09:24 PM Tom_L: which _would_ be shown different
09:24 PM rue_shop4: well
09:25 PM Tom_L: cutter diameter, neck to thread is the same
09:25 PM rue_shop4: whats number 10?
09:25 PM Tom_L: which tells me the thread isn't any deeper
09:25 PM rue_shop4: in size
09:25 PM rue_shop4: I wonder if
09:25 PM Tom_L: 2 sizes under 1/4
09:25 PM Tom_L: about the same size as an M5
09:26 PM Tom_L: the thread pitch would be a tiny bit finer on the M5
09:26 PM Tom_L: but cad can fix that
09:26 PM Tom_L: i want to try single point thread cutting
09:26 PM Tom_L: and i figure i use more of those than anything
09:27 PM rue_shop4: M5 and 10-32 are ALMOST identicle
09:27 PM rue_shop4: slight difference in dia
09:27 PM Tom_L: right
09:27 PM Tom_L: pitch is a little different
09:27 PM rue_shop4: if you take the bolts, the threads almost perfectly match up, ever over like an inch
09:27 PM rue_shop4: and zhanx the sugar thing dosn't work
09:28 PM Tom_L: i don't have a holder for the sherline spindle thread
09:28 PM Tom_L: and i'm not gonna spend that much anyway
09:28 PM rue_shop4: spindle thread?
09:28 PM Tom_itx: https://www.ebay.com/itm/3-4-10-32-TPI-SINGLE-PITCH-THREAD-MILL-BRAND-NEW-TiALN-COATED/151856984850?hash=item235b61b312:g:psUAAOSwtaRa9lax
09:28 PM rue_shop4: on the bottom under the bearing block?
09:28 PM Tom_L: 3/4"
09:29 PM Tom_L: i forgot the thread count
09:29 PM Tom_L: probably 16
09:29 PM rue_shop4: you have a lathe...
09:29 PM Tom_L: no the spindle head
09:29 PM Tom_L: for the tool holders
09:29 PM rue_shop4: the outside thread
09:29 PM Tom_L: i don't think i can cut threads on that old lathe
09:30 PM rue_shop4: the one you have the collar ring for
09:30 PM Tom_L: the inside thread for the tool holder
09:30 PM rue_shop4: inside!?
09:30 PM rue_shop4: there are no threads in three...
09:30 PM Tom_L: the collets
09:30 PM rue_shop4: its just a bolt
09:30 PM rue_shop4: its like a 6" x 1/4" bolt
09:30 PM rue_shop4: the drawbolt... yea?
09:31 PM Tom_L: no

09:32 PM rue_shop4: I'll have to look later
09:32 PM rue_shop4: the world is getting stupid
09:33 PM Tom_L: the 1" steel tool holders with the big thread inside
09:33 PM rue_shop4: ok
09:33 PM rue_shop4: does it fit a 3/4" nut?
09:34 PM Tom_L: it's 3/4 16
09:34 PM Tom_L: so probably so
09:35 PM Tom_L: i never use the collets
09:36 PM rue_shop4: doesn't fit any of the nuts I have
09:37 PM rue_shop4: the thread is off from my closest, its almost like its metric
09:38 PM Tom_L: they are made to be tight
09:38 PM Tom_L: average hardware isn't
09:43 PM rue_shop4: 3/4-16, my 3/4" nut is 10
09:43 PM rue_shop4: would you like me to see if I can make a nut for it?
09:43 PM rue_shop4: I'd have to thread it thru
09:47 PM rue_shop4: Tom_L did you see the encoder images?
10:01 PM Tom_L: no not yet
10:02 PM Tom_L: that was why i thought about threading it with the mill instead of the lathe
10:02 PM Tom_L: a cnc lathe could stop right where it needed to but i'm not that good with the manual lathe and i've never single pointed a thread on it
10:04 PM Tom_L: it's not listed under projects/encoder!!!!
10:07 PM Tom_L: http://ruemohr.org/%7Eircjunk/projects/lathe/p1050160.jpg
10:07 PM Tom_L: what's the bottom rear pulley for?
10:08 PM Tom_L: nice little bump knurl
10:11 PM Tom_L: we had thread knurls like that but they were geared together
10:12 PM Tom_L: you'd push em in all the way to the centerline to roll threads
10:21 PM Tom_L: http://ruemohr.org/~ircjunk/projects/siggen/p1100734.jpg
10:21 PM Tom_L: ahh found it
10:22 PM Tom_L: i think the others will work better
10:24 PM Tom_L: k, i'm goin to bed
10:28 PM Tom_L: https://freenode.net/news/spamfilter
11:17 PM rue_mohr: that rear bottom pulley is the motor
11:20 PM rue_mohr: will the spam filter work then
