12:00 AM rue_bed: we can try
12:05 AM zhanx: k one sec
12:05 AM zhanx: https://imgur.com/a/QAmCNUY
12:05 AM zhanx: tray for the router mounts to the front of that, motor mounted to the top, bearing block on the inside bottom
12:15 AM zhanx: that would work then
12:15 AM zhanx: fits it all in a 1" triangle
12:34 AM zhanx: rue_mohr, ?
01:21 AM rue_mohr: cant mount that router on a 1" triangle
01:21 AM rue_mohr: not strong enough
01:21 AM rue_mohr: ...?
01:22 AM zhanx: on the slots are for the mount
01:22 AM zhanx: the mount is the issue
01:22 AM zhanx: you can bearing it
01:22 AM zhanx: heck make it 2" to be in your max zone
01:23 AM rue_mohr: needs to hold a 2HP router stable when its 6" off the gantry...
01:23 AM zhanx: what is more stable than a triangle?
01:23 AM rue_mohr: its given me an idea I'll play with tho
01:23 AM zhanx: k
01:23 AM zhanx: duel slides on the same idea
01:42 AM rue_shop1: #include "PinChangeInterrupt.h" <--- hahah
01:42 AM rue_shop1: their quotes...
01:42 AM rue_shop1: so its not an arduino library
01:45 AM rue_shop1: https://code.google.com/archive/p/arduino-pinchangeint/downloads
01:45 AM rue_shop1: ugh
01:50 AM rue_shop1: hahah it was abandoned in 2012 and its out of date with the UI
01:50 AM rue_shop1: well arduino really fell down on that front
01:55 AM zhanx: arduino does that
03:00 AM Tom_L: find out what cnc's he's got
03:01 AM Tom_L: will he make parts for you?
03:19 AM rue_mohr: I just wanted to show himthe mold as a point of interest
03:19 AM rue_mohr: so I'm thinking about making a concrete mixer
03:20 AM rue_mohr: looking at designs I realized I best have a big gear
03:20 AM rue_mohr: .. and I have two ring gears in the basement
03:20 AM rue_mohr: so, looking at them, their a bit small, but whatever
03:20 AM rue_mohr: to then I was thinking I need a badass bearing
03:20 AM rue_mohr: ... so, in the basement I have the hub of a car...
03:23 AM rue_mohr: yea, 8 stud, so its a hair large
05:06 AM Tom_L: lemme know what he thinks
04:26 PM rue_mohr: he wsn't in :(
04:39 PM rue_mohr: 2 hrs of driving, I'm tired
06:04 PM Tom_L: should have called
09:10 PM rue_mohr: I was doing other things along the way
10:20 PM Tom_L: have you ever tried setting up a git server on one of your pcs?
10:20 PM rue_shop1: no, version control does not apply to me cause nobody helps me on my doing projects
10:20 PM rue_shop1: it would be WAAAAAAAAAAAY more trouble than it would ever be worth
10:21 PM Tom_L: just a good way to not lose code
10:21 PM rue_shop1: it would be WAAAAAAAAAAAY more trouble than it would ever be worth
10:21 PM Tom_L: https://www.linux.com/tutorials/how-run-your-own-git-server/
10:21 PM Tom_L: not really
10:21 PM rue_shop1: i make copies of dirs when i'm at turning points
10:21 PM rue_shop1: yes
10:22 PM rue_shop1: using it is a LOT of bother
10:22 PM rue_shop1: and there is no point
10:22 PM rue_shop1: if I have a dir, I can just access it, no commands to pull or push or update or anything
10:22 PM Tom_L: just thinking of something to do that i haven't done
10:22 PM rue_shop1: I just go use the files
10:22 PM rue_shop1: mm
10:22 PM Tom_L: i have no reason to have one either
10:22 PM rue_shop1: if you have a team, git has worth
10:23 PM Tom_L: you're not on my team?
10:23 PM Tom_L: :(
10:23 PM rue_shop1: heh
10:23 PM rue_shop1: we never code togethor
10:23 PM Tom_L: not anymore
10:23 PM Tom_L: that thing i did with rif was fun
10:23 PM rue_shop1: I dont know if we did in the early days did we?
10:23 PM rue_shop1: there were lots of fun projects
10:24 PM Tom_L: next time you're by, find out what kind of cnc's the guy has
10:25 PM Tom_L: what's he do with em?
10:25 PM rue_shop1: their commercial ones
10:25 PM rue_shop1: he makes tops
10:25 PM Tom_L: i know that
10:25 PM Tom_L: tops!
10:25 PM rue_shop1: yea
10:25 PM Tom_L: that's it?
10:25 PM rue_shop1: prettymuch, it seems, yea
10:25 PM Tom_L: lathes?
10:25 PM rue_shop1: yup
10:25 PM Tom_L: no mills?
10:25 PM rue_shop1: w/ feeder chucks
10:25 PM Tom_L: i ran an okuma cnc lathe
10:26 PM rue_shop1: he has a mill there too, dont recall if its one or two
10:26 PM Tom_L: programmed it etc
10:26 PM rue_shop1: :)
10:26 PM Tom_L: my bud's trying to get it back
10:26 PM Tom_L: he's not sure why
10:26 PM Tom_L: he's got 2 of his old cnc mills back
10:26 PM rue_shop1: was at the scrapper
10:27 PM rue_shop1: saw a small drillpress in the pile
10:27 PM rue_shop1: looked ok, but I couldn't, I have too much stuff
10:27 PM rue_shop1: :(
10:27 PM Tom_L: no the ppl he sold his buisness to fucked em up and were gonna get rid of em
10:27 PM rue_shop1: surprise
10:27 PM Tom_L: i think he had to rebuild the spindle on the 2nd one
10:28 PM Tom_L: that's not cheap
10:28 PM Tom_L: but he still does work for them
10:28 PM Tom_L: stuff they can't figure out
10:28 PM Tom_L: or don't want to bother with
10:28 PM rue_shop1: heh
10:29 PM Tom_L: so they pay for themselves
10:29 PM rue_shop1: I briefly thought about helping that shop automate that lathe I was showing you
10:29 PM Tom_L: don't remember it
10:29 PM rue_shop1: but if they cant do it themselvs, they would never be able to use it
10:30 PM rue_shop1: old japanese thing with a pegboard programmer that was missing
10:31 PM Tom_L: why you makin a cement mixer?
10:32 PM rue_shop1: checked craigslist, $140, but its a pain to get, waiting for a reply
10:34 PM rue_shop1: I got rid of the images of the machine
10:34 PM Tom_L: i think i somewhat remember it but i look at alot of old iron
10:34 PM rue_shop1: I should go thru /images and blow out lots of stuff
10:34 PM rue_shop1: yup
10:34 PM rue_shop1: LOTS of relays
10:35 PM rue_shop1: lots of endstop programming
10:35 PM rue_shop1: back in the days when you spent a lot of time setting up a job
10:35 PM Tom_L: couldn't have been any harder than the multi spindle lathes i ran
10:35 PM rue_shop1: but I dont think they could run it
10:36 PM rue_shop1: they got it in an auction
10:36 PM rue_shop1: wanted to use it to make lots of money
10:36 PM rue_shop1: like I say, I could
10:36 PM rue_shop1: but I'd have to be the guy running it
10:36 PM Tom_L: https://www.youtube.com/watch?v=7WH12VtsIVs
10:37 PM Tom_L: i ran a whole row of those years back
10:37 PM rue_shop1: this was just 1 chuck, a turret machine
10:39 PM Tom_L: gawd watching those bring back memories
10:41 PM Tom_L: they had some chuckers and turret lathes too
10:41 PM rue_shop1: large runs I take it
10:41 PM rue_shop1: what was a min. volume to make it worth it?
10:41 PM Tom_L: 6k parts a shift on one brass part i did
10:42 PM Tom_L: and i usually ran 4-5 machines
10:42 PM rue_shop1: big run
10:42 PM Tom_L: 3 6 spindle and 1 8 spindle.. the only one they had
10:42 PM rue_shop1: did the same shop have other equipment for smaller runs?
10:43 PM Tom_L: 12' bars 6 at a time
10:43 PM Tom_L: there wasn't any smaller runs
10:43 PM rue_shop1: so no 1k pieces
10:43 PM Tom_L: it was an in house factory machine shop
10:43 PM Tom_L: well some parts were shorter runs but some machines ran the same part all the time
10:44 PM Tom_L: i was lucky to have the best 'row' of machines they had
10:44 PM rue_shop1: disposable parts or just LOTS of them?
10:45 PM Tom_L: coleman lanterns, cookstoves, propane parts, home furnace parts etc
10:45 PM rue_shop1: ah yea
10:45 PM rue_shop1: nice
10:46 PM Tom_L: the screw cap you unscrew to fill the tank?
10:46 PM rue_shop1: ok
10:46 PM Tom_L: i probably made that for you
10:46 PM rue_shop1: prolly by you :)
10:46 PM rue_shop1: I'll tell me uncle, he's a camping/hiking guru
10:46 PM Tom_L: and most of the pump assembly parts
10:46 PM Tom_L: the check valve and pump base etc
10:47 PM Tom_L: propane regulators etc
10:47 PM Tom_L: they ran the tanks thru a conveyor furnace right across the isle from me
10:47 PM Tom_L: and the paint room was just at the end of that
10:48 PM Tom_L: green red and brown were about the only colors they had
10:49 PM Tom_L: they tore down the building now
10:49 PM Tom_L: i dunno if they even still make parts
10:50 PM Tom_L: that had to be in the late 70's iirc
11:01 PM rue_shop1: so, writing my own bandsaw speedometer code
11:01 PM rue_shop1: I'll want to know the blade speed when I get the metal blade
11:01 PM rue_shop1: try to not burn a $40 blade in the first 8 seconds of use
11:02 PM Tom_L: why not use pulleys
11:02 PM Tom_L: then you know how fast it's going
11:03 PM rue_shop1: its got them, I got hooked on the speedometer idea, cause I'd thought of it and then someone else started building one
11:03 PM rue_shop1: hey I already cast an aluminum project box for it :)
11:04 PM rue_shop1: lcd is working, I need to think
11:04 PM rue_shop1: I want a 16 bit timer
11:05 PM rue_shop1: m328
11:05 PM Tom_L: tiny 10
11:05 PM rue_shop1: heh
11:05 PM rue_shop1: it could be
11:05 PM Tom_L: has a 16 bit timer
11:05 PM rue_shop1: m328
11:05 PM rue_shop1: dont have a serial lcd set up
11:05 PM rue_shop1: and t10 would have to be assembler
11:05 PM Tom_L: no
11:05 PM Tom_L: not now
11:06 PM rue_shop1: its got 1k
11:06 PM rue_shop1: ?
11:06 PM Tom_L: i did one in c iirc
11:06 PM Tom_L: the c compiler supports it now
11:06 PM rue_shop1: heh, if I want cheap I'd go with the arm :)
11:06 PM Tom_L: now being a long time ago
11:07 PM rue_shop1: those new avrs are pretty messed up
11:07 PM rue_shop1: the tiny841
11:07 PM rue_shop1: thats just wrong
11:07 PM Tom_L: i couldn't tell you about any of em
11:07 PM rue_shop1: counter 1 is 16bits
11:08 PM rue_shop1: microchip is right on schedule doing their thing
11:08 PM Tom_L: i'm sure my programmer doesn't work on any of em
11:09 PM rue_shop1: they didn't change that yet
11:09 PM rue_shop1: I'm waiting
11:09 PM rue_shop1: their almost overdue
11:09 PM Tom_L: i thought i did a c sample for the t10 but i can't find it
11:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/avr/c_bits/K&R_C_2nd.pdf
11:10 PM Tom_L: there's that if you ever want it
11:11 PM rue_shop1: ooo
11:17 PM rue_shop1: m328
11:17 PM rue_shop1: timer 1 overflow
11:17 PM rue_shop1: isr name...
11:17 PM rue_shop1: TIMER2_OVF_vect
11:21 PM rue_shop1: ok
