11:31 AM rue_mohr: its an oil mix isn't it?
11:32 AM Tom_shop: water base
11:33 AM rue_mohr: yea, but I'd expect hydroscopic oil to fend off freezing
11:33 AM Tom_shop: i got some that's ok
11:34 AM Tom_shop: it's just like a slushie
11:35 AM rue_mohr: I should go run the generator

11:44 AM rue_mohr: need shower and breakfast...
11:44 AM Tom_shop: been there done that

12:13 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/SoftJaws3.jpg
12:14 PM Tom_L: notice they're held apart at the bottom with a spacer
12:58 PM rue_mohr: new new jaws
12:59 PM rue_mohr: I figured you would be overcutting some that had been round the block a few times
01:01 PM Tom_L: most of them were wore out
01:03 PM Tom_L: notice they're a bit taller than the old ones
01:04 PM Tom_L: found a tiny bug in my post i'm fixing as well
01:20 PM rue_mohr: ?
01:20 PM rue_mohr: so
01:20 PM Tom_L: nothing major and only shows up on a drill cycle
01:20 PM Tom_L: but it's fixed now
01:20 PM rue_mohr: I have to tighten that screw that holds the gasket *IN* the hot water valve of the bathtub
01:21 PM Tom_L: eating soup then i'm gonna go try to cut it
01:21 PM rue_mohr: :)
01:21 PM rue_mohr: just set on a pot of water
01:21 PM rue_mohr: maybe I should get dressed then
01:21 PM Tom_L: i got the heat on
01:21 PM Tom_L: but it takes a while to warm up
01:22 PM rue_mohr: ma says she's gonna come bring some groceries,
01:22 PM rue_mohr: I think she's just spite-ing the snow
01:22 PM rue_mohr: wish she wouldn't
01:22 PM Tom_L: i thought she was staying with you
01:22 PM rue_mohr: there are a lot of people sliding all over the road
01:22 PM rue_mohr: she alternates
01:22 PM Tom_L: still got the boat house?
01:22 PM rue_mohr: she lives on her houseboat at the marina
01:23 PM Tom_L: err yeah
01:23 PM Tom_L: does that water freeze up? or is it saltwater..
01:23 PM rue_mohr: ocean, it does ice up a bit tho
01:24 PM rue_mohr: i think the fresh stuff sits on top
01:24 PM Tom_L: ok soup gone time to try this
01:26 PM rue_mohr: todo list
01:26 PM rue_mohr: - do nfs test
01:26 PM rue_mohr: - sort package

03:13 PM Tom_L: https://www.youtube.com/watch?v=z47eQH6NaTE
03:16 PM Tom_L: next?
03:55 PM rue_mohr: ?
03:56 PM rue_mohr: oooo
03:56 PM rue_mohr: cool!
03:56 PM rue_mohr: you did the pipe with a tap or the cnc?!
03:56 PM rue_mohr: I just finished getting the generator working again
03:56 PM rue_mohr: man it can produce a LOT of attitude!
03:57 PM rue_mohr: that looks awesome!
03:57 PM rue_mohr: do you still use the touch-off sensor for zeroing?
04:01 PM rue_mohr: what do you figure it weighs?
04:04 PM Tom_L: no idea on weight
04:04 PM Tom_L: doesn't register on the bath scale
04:05 PM rue_mohr: heh
04:06 PM rue_mohr: heh, I wonder if we can get it here before the other guy has a chance to thread the one I started!
04:06 PM rue_mohr: how do I send you funds anyhow?
04:06 PM Tom_L: maybe half pound, i dunno
04:07 PM rue_mohr: hmm, I have a kinda circular problem with the editor
04:08 PM rue_mohr: the editor contains a small editor, for dialog boxes
04:08 PM rue_mohr: it also has a content storage system
04:08 PM Tom_L: i was pleased with the program. it ran the first time save that post glitch
04:08 PM rue_mohr: but the display system needs a content storage system for a buffer
04:08 PM Tom_L: no adjustments
04:09 PM rue_mohr: its nice when one goes off first time eh?
04:09 PM rue_mohr: I had a 3d printed parts set that worked the first time
04:09 PM rue_mohr: the design didn't work, but all the parts came out exactly as planned
04:09 PM Tom_L: figured i'd have more grief than i did
04:10 PM Tom_L: i just hope the thread fits or you'll have a nice paperweight
04:10 PM rue_mohr: :)
04:11 PM Tom_L: ups or fedex would cost too much ehh?
04:11 PM rue_mohr: I made an automatic cat brush last night
04:11 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1360670685685641217
04:11 PM rue_mohr: definitly
04:11 PM Tom_L: k
04:12 PM Tom_L: does the cat use it?
04:12 PM rue_mohr: is plain post more expensive?
04:12 PM rue_mohr: not *yet*
04:12 PM rue_mohr: I have more capnip ready
04:12 PM Tom_L: no usps is probably the most economical but it's gone up
04:12 PM rue_mohr: I think if they try it they will like it
04:13 PM Tom_L: unless they get their tail wound up in it
04:13 PM rue_mohr: the couriers charge $50 at the border
04:13 PM rue_mohr: no its not a torquie motor
04:13 PM Tom_L: you think it's worth shipping it?
04:13 PM Tom_L: dunno what the cost is gonna be
04:13 PM rue_mohr: shall we find out?
04:13 PM Tom_L: i'm game
04:14 PM rue_mohr: The things were $50 online, thats not including shipping (or the fact they couldn't sell me one)
04:14 PM rue_mohr: I really hate it when a place is the outlet for a brand or has something on their page and cant actually sell it to ya
04:16 PM rue_mohr: <rue_mohr> <rue_mohr> todo list
04:16 PM rue_mohr: <rue_mohr> <rue_mohr> - do nfs test
04:16 PM rue_mohr: <rue_mohr> <rue_mohr> - sort package
04:16 PM rue_mohr: ok
04:16 PM rue_mohr: I hate having gas on my hands, cant get that out
04:18 PM Tom_L: ok i'll round up a box and do you want me to see what it costs to ship first?
04:33 PM rue_mohr: sure, how can I get you money for toys and shipping?
04:34 PM rue_mohr: do you have paypal set up?
05:09 PM Tom_L: yes
05:14 PM rue_mohr: ok
05:14 PM rue_mohr: last thing is the NFS test
05:14 PM rue_mohr: mmm
05:15 PM rue_mohr: I desire more sleep
05:15 PM Tom_L: naw, that's just your imagination
05:17 PM rue_mohr: "
05:17 PM rue_mohr: I wonder what read path you're taking through vfs.. can you set some tracepoints on the server, ala:
05:17 PM rue_mohr: egrep nfsd_\(read\|write\) /sys/kernel/debug/tracing/available_events > /sys/kernel/debug/tracing/set_event
05:17 PM rue_mohr: Then send the READ from the client, and cat /sys/kernel/debug/tracing/trace_pipe on the server again?
05:17 PM rue_mohr: "
05:19 PM polprog: what's on the menu today?
05:19 PM Tom_L: steak
05:20 PM Tom_L: polprog, you see the part i did for rue?
05:21 PM polprog: these links up ther?
05:21 PM Tom_L: yes
05:22 PM polprog: looks neat
05:22 PM polprog: that's for testing fire extinguisher pressure i suppose?
05:22 PM polprog: a manometer goes on one end?
05:22 PM Tom_L: that's what he said
05:22 PM polprog: clever :P
05:22 PM Tom_L: no idea
06:23 PM aandrew: what the fuck
06:23 PM aandrew: if (tid < NUM_TARGETS) {
06:23 PM aandrew: ++tid;
06:23 PM aandrew: } else {
06:23 PM aandrew: tid = 0;
06:23 PM aandrew: }
06:23 PM aandrew: tid is uint8_t
06:23 PM aandrew: NUM_TARGETS is 5 (verified with printf)
06:24 PM aandrew: oh
06:24 PM aandrew: got it
06:24 PM aandrew: 500rpm on an M4 ledscrew is still too slow for what I want
06:27 PM Tom_L: wtfbbq
06:29 PM aandrew: sorry
06:29 PM aandrew: let me get a quick video
06:29 PM aandrew: don't mind the Rattatouille in the background
06:29 PM Tom_L: no sound anyway
06:31 PM Tom_L: rue_mohr, i think i got the threads close enough to the bottom you may not need a relief cut
06:35 PM aandrew: Tom_L: https://youtu.be/jyzL76iLjCI
06:38 PM Tom_L: cute :)
06:43 PM aandrew: yeah I needed a quick an dirty way to move the target RFID card to repeatable positions to take measurements
06:44 PM aandrew: my son did the first iteration then got bored so I had to finish the lego
06:45 PM aandrew: those cross axles have too much play to have the "wall" slide nicely without wobbling, and the M4 leadscrew is also got a wow to it
06:45 PM aandrew: but close enough for hte girls I go with, as my old boss would say
06:45 PM aandrew: oh and that ToF distance sensor has a 50-4000mm range, I have another one that is 5-100 which is more what I'm after
06:46 PM polprog: what are you building?
06:46 PM aandrew: could've done it way more cheap just by homing the platform and timing the motor but this was an excuse to play with that sensor :-)
06:47 PM aandrew: polprog: one of my contracts is a unit that reads form 32 RFID readers. I needed a way to test the sense range in a repeatable way while I tweak the code
06:47 PM polprog: ahh
06:47 PM polprog: i know there are some RFID (?) technologies that have a couple-ten feet distance
06:47 PM polprog: for warehouse inventory
06:48 PM Tom_L: he really just wanted to play with his legos
06:48 PM aandrew: yeah this one is aiming at 4" for a similar warehouse application (monitoring position of work pallets)
06:48 PM polprog: 4 inch?
06:49 PM aandrew: yeah
06:49 PM polprog: nice
06:49 PM aandrew: basically "which station has work order X"
06:49 PM aandrew: Tom_L: heh more an excuse to play with that ToF sensor
07:38 PM aandrew: I just realized I could 3d print some bushings with an OD for the "hole" in the lego bar that those cross axles are running through, and an ID that helps close up that slop
07:38 PM aandrew: definitely overthinking it, that's the engineer in me
07:41 PM Tom_L: i'm more of a ' look at it and build one ' guy
07:50 PM rue_mohr: awake again
07:50 PM Tom_L: so rue_mohr
07:50 PM Tom_L: what other crap can i stuff in this box?
07:50 PM Tom_L: actually we might wanna keep the weight down
07:53 PM rue_mohr: heh
07:53 PM Tom_L: still at 2022?
07:53 PM rue_mohr: whats another 10lbs of FR4?
07:53 PM rue_mohr: :)
07:53 PM rue_mohr: haha
07:53 PM rue_mohr: yes, same address!
07:53 PM Tom_L: i'd need a much bigger box for that
07:55 PM Tom_L: ok it's all boxed up
07:55 PM Tom_L: i'll send it overnite fedex mkay?
07:57 PM rue_mohr: I wonder how that would arrive at this end
07:58 PM Tom_L: 6 weeks later
07:58 PM rue_mohr: I know fedex, and ups wont do pickups here, we have to go to vancouver
07:59 PM rue_mohr: but I'v seen a UPS truck do a dropoff here
07:59 PM Tom_L: it won't fit in a mailbox
07:59 PM Tom_L: smallest box i had
08:00 PM rue_mohr: np
08:01 PM rue_mohr: the regular post system seems to be able to deal with anything, the couriers are usually quite awkward about stuff, for pickups anyhow
08:04 PM Tom_L: weather permitting it'll go monday
08:09 PM rue_mohr: monday not a holiday over there?
08:09 PM Tom_L: oh, i guess it is
08:19 PM aandrew: rue_mohr: wtf?!
08:19 PM aandrew: rue_mohr> I know fedex, and ups wont do pickups here, we have to go to vancouver
08:49 PM rue_mohr: yep
08:49 PM rue_mohr: you can get the local couriers to do a hand-off, kinda deliver it for you
08:53 PM rue_mohr: running boiler
08:53 PM rue_mohr: tank temp needs to come up
09:01 PM Tom_L: there used to be a fire inspection company nearby, i dunno if they're even there now. i thought about taking that thing there and see if they test tanks and maybe had one that size
09:01 PM Tom_L: would be a real long shot
09:01 PM Tom_L: and they'd probably look at me like i was crazy
09:09 PM aandrew: rue_mohr: that's insane.
09:09 PM Tom_L: https://www.gaugestools.com/1-1-2-16-un-thread-ring-plug-gauge/
09:09 PM aandrew: Tom_L: what are you testing?
09:09 PM aandrew: or needing tested
09:09 PM Tom_L: could get a test gage for $121
09:09 PM Tom_L: 1.5" x 16 tpi thread
09:10 PM Tom_L: we're gonna chance it
09:10 PM aandrew: aha. scuba places can sometimes do that kind of test but that might be a little specific
09:16 PM rue_mohr: Tom_L, they might ask to buy one
09:16 PM rue_mohr: aandrew, :)
09:16 PM Tom_L: https://www.ebay.com/itm/Hemco-M16-x-1-5-6H-6916-5990-Thread-Plug-Gage/274386798559?hash=item3fe2ba47df:g:hRcAAOSwR05evZob
09:16 PM Tom_L: is that it?
09:17 PM Tom_L: no that's metric
09:17 PM rue_mohr: aandrew, its a test cap for fire extinguishers
09:17 PM rue_mohr: for pressure testing them
09:18 PM rue_mohr: we have a lot of a specific type here
09:18 PM rue_mohr: nobody can sell me the test cap for them
09:18 PM rue_mohr: }:[ "BUT ITS ON YOUR WEBPAGE!!!"
09:18 PM rue_mohr: "we cant get it"
09:19 PM rue_mohr: honestly I have that problem with most things I need
09:19 PM rue_mohr: its like I'm the only one out there
09:20 PM rue_mohr: my answer to "we dont have it because nobody buys it" is "I'M THE NOBODY BUYING THEM!"
09:20 PM Tom_L: a 12' bar of 1.750 hex is $585.00
09:21 PM rue_mohr: that almost sounds cheap
09:21 PM rue_mohr: 12" or 12'
09:21 PM Tom_L: shipping not included
09:21 PM rue_mohr: lol
09:21 PM Tom_L: https://www.colliermiller.com.au/brhex134-brass-hex-bar-1-750
09:21 PM Tom_L: can you find the length?
09:21 PM Tom_L: most are 12'
09:21 PM Tom_L: i bought an aluminum bar once
09:22 PM rue_mohr: $4 per inch
09:22 PM rue_mohr: I suppose thats about what I'd expect then
09:22 PM rue_mohr: Per MTR inc GST
09:22 PM rue_mohr: no wait
09:23 PM rue_mohr: its MTR their version of meter?
09:23 PM Tom_L: i dunno
09:23 PM Tom_L: i got an old old barstock catalog here somewhere
09:23 PM rue_mohr: its .au
09:23 PM rue_mohr: thats for 1m
09:23 PM Tom_L: i'd never get it
09:24 PM Tom_L: from Au? :)
09:24 PM rue_mohr: its $16/inch
09:24 PM rue_mohr: which is much more towards what I'd expect
09:24 PM Tom_L: how many do you want?
09:24 PM rue_mohr: heh
09:24 PM Tom_L: make it worth while and i'll get a plug gage
09:25 PM rue_mohr: :S
09:26 PM Tom_L: https://www.onlinemetals.com/en/buy/brass/1-75-brass-hex-bar-360-h02-extruded/pid/1327
09:27 PM Tom_L: $120 / ft
09:27 PM Tom_L: 12' bar $879
09:32 PM Tom_L: https://www.onlinemetals.com/en/buy/brass/2-125-brass-round-bar-360-h02-extruded/pid/20385
09:32 PM Tom_L: that's the size bar i had
09:32 PM Tom_L: $11.83 / inch
09:33 PM Tom_L: roughly $15 per part
09:35 PM Tom_L: those bar machines i ran would chew a bar like that up in 20 min
09:40 PM rue_mohr: I think the prices went crazy when it became a trade commodity
09:41 PM Tom_L: brass was never one of the cheaper metals
09:41 PM rue_mohr: I dont get that tho
09:41 PM rue_mohr: copper was pretty cheap
09:41 PM rue_mohr: tin?
09:41 PM Tom_L: i never priced any that size
09:42 PM rue_mohr: I suspect per lb its the same
09:42 PM Tom_L: i did a job long time ago with i think .500 square bar
09:42 PM Tom_L: make some recessed lock receptacles for cabinets
09:43 PM Tom_L: just a chunk with a slot and 2 mounting holes
09:43 PM rue_mohr: do you know if they sold back the shavings from the bar machines?
09:43 PM Tom_L: oh hell yes
09:43 PM rue_mohr: that makes sense
09:43 PM Tom_L: they had a spinner to get rid of alot of the oil too
09:44 PM Tom_L: i'd fill probably 3-4 dumpsters full a shift
09:44 PM rue_mohr: I cringe when I see the brass prop shafts for old boats
09:44 PM Tom_L: between the 4 i usually ran
09:44 PM rue_mohr: and I imagine the odd goofed part
09:44 PM Tom_L: 6 1" roundbar brass every 20 min
09:45 PM Tom_L: one was 1/2" or thereabouts round brass
09:45 PM rue_mohr: they goof up a few parts when you start a run, dont they?
09:45 PM Tom_L: yeah on the setup
09:45 PM Tom_L: i was pretty good at that though
09:45 PM Tom_L: but that 1" part ran 5600 parts a shift
09:45 PM rue_mohr: yep
09:46 PM rue_mohr: how long between re-adjusting?
09:46 PM Tom_L: ever own a coleman lantern?
09:46 PM Tom_L: sometimes you could run the whole run
09:46 PM rue_mohr: not myself, you said once tho
09:46 PM Tom_L: i made alot of the parts on them
09:46 PM rue_mohr: would they just order like 10k at a time?
09:46 PM Tom_L: one was the brass filler cap
09:47 PM Tom_L: that machine ran all the time just that one part
09:48 PM Tom_L: it was in house so whenever the assy line needed more we ran them
09:48 PM Tom_L: but the filler caps were on just about everything so it ran all the time
09:48 PM Tom_L: along with 2 other machines i ran for the pump parts
09:49 PM Tom_L: they'd bring a whole cart of material
09:49 PM Tom_L: probably 100+ bars
09:50 PM Tom_L: did a bunch of hose barb fittings.. that stuff went thru real quick
09:50 PM Tom_L: i used to have one of every part i did but i think i tossed em finally
09:52 PM Tom_L: they didn't turn all the part, they used form tools on those
09:54 PM aandrew: interesting
09:55 PM Tom_L: https://www.youtube.com/watch?v=7WH12VtsIVs
09:55 PM Tom_L: to give you an idea
09:55 PM Tom_L: i ran the 52 as one of them
09:56 PM Tom_L: one i ran had 8 spindles
09:58 PM rue_mohr: how often were all 8 used?
09:58 PM rue_mohr: I mean, for a process step
09:58 PM Tom_L: all the time
09:58 PM aandrew: that is a cool looking machine but I could not see what it was doing
09:58 PM Tom_L: 2 had brakes for cross drill / tap
09:59 PM rue_mohr: so the process would always be broken into 8 for that machine?
09:59 PM Tom_L: 6 or 8 depending on the machine
09:59 PM rue_mohr: aandrew, it looks like they were doing a dry run
09:59 PM Tom_L: they had only 1 8 spindle
09:59 PM Tom_L: yeah they were probably doing a setup there
09:59 PM Tom_L: you can run it in manual and set each station before it goes auto
09:59 PM rue_mohr: must ahve been an interesting job setting up a part into a fixed number of processes
10:00 PM rue_mohr: I imagine a few steps would do more than one thing at a time
10:00 PM Tom_L: all mechanical... cams n gears
10:00 PM rue_mohr: a shop up here got an old automated machine
10:00 PM rue_mohr: I think I asked you about it
10:00 PM rue_mohr: it was electronic, early
10:00 PM Tom_L: you generally had a cross slide cutting something and the main slide drilling reaming or tapping
10:00 PM rue_mohr: looked like they had maybe plugboard programming
10:01 PM rue_mohr: but there was a lot missing
10:01 PM Tom_L: those were all mechanical
10:01 PM rue_mohr: they wanted to know if I could set it up to make stuff for them
10:01 PM rue_mohr: I had to decline, a person would have to know as much about the machine as the job, and they weren't academics
10:01 PM rue_mohr: too bad
10:02 PM rue_mohr: it would have made a nice toy
10:02 PM rue_mohr: 1 autofeeding spindle
10:02 PM Tom_L: now everything is cnc
10:02 PM rue_mohr: yea, this was that pre-era
10:02 PM Tom_L: maybe a davenport
10:02 PM Tom_L: iirc those may have been 1 spindle
10:02 PM rue_mohr: move your end stops and sequence movement based on them
10:02 PM Tom_L: brown & sharp were the midsize ones
10:02 PM aandrew: so that thing was like the machining equivalent to a real ladder logic system before PLCs?
10:02 PM Tom_L: davenport were for tiny parts
10:03 PM Tom_L: aandrew, i suppose you could look at it that way
10:03 PM rue_mohr: aandrew, hard to describe, kinda?
10:03 PM Tom_L: all the cross slides went in at the same time depending on the cam you put in them
10:05 PM rue_mohr: did the cams have to be made or were they kinda programmable
10:06 PM Tom_L: sometimes they would make special ones
10:06 PM Tom_L: alot of times we used general travel cams depending on the job and who stole your cams
10:06 PM rue_mohr: i saw a "programmable" cam on a boiler at the hospital I thought was cool
10:06 PM rue_mohr: it adjusted the air rate per fuel
10:06 PM Tom_L: there was a big drum cam that controlled the travel and timing on the main slide
10:07 PM rue_mohr: it had movable segments, with a spring to "average the curve"
10:14 PM Tom_L: i posted the final program up there if you wanna look it over
10:15 PM Tom_L: feel free to run a few if you want :)
10:15 PM rue_mohr: hah
10:15 PM rue_mohr: do you know how much explaining I would have to do to get that bit from ANYWHERE in canada?
10:16 PM Tom_L: the threadmill?
10:16 PM rue_mohr: I'm lucky if I don't have to explain to the building supplies store what a ladder is if I want to buy one
10:16 PM Tom_L: odd enough i used a 3/8 threadmill on that
10:16 PM rue_mohr: and yes, last time I went to buy a ladder it was a fail
10:17 PM Tom_L: it was smaller so i could get closer to the bottom
10:17 PM rue_mohr: do they mostly go by pitch or cut depth?
10:17 PM Tom_L: pitch range
10:18 PM Tom_L: if you think about it you can see why
10:18 PM rue_mohr: totally
10:18 PM Tom_L: the hole size vs the cutter depth
10:18 PM rue_mohr: they have to modify the shape for the cut over the arch of the thread
10:18 PM Tom_L: the teeth are bigger on the bigger ones limiting what you can do with them
10:18 PM rue_mohr: you wrote the spiral macro didn't you?
10:19 PM Tom_L: yes
10:19 PM Tom_L: it works great now too
10:19 PM Tom_L: that's why i was able to fiddle with the size so quickly
10:19 PM rue_mohr: :)
10:20 PM Tom_L: it's up there too somewhere
10:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/THREADMILL.MCL
10:27 PM rue_mohr: ELMT_SEQ ?
10:28 PM Tom_L: tells it where to insert the new element
10:28 PM Tom_L: i forget what the vars tell it
10:29 PM rue_mohr: looks like it took a while!
10:29 PM Tom_L: before / after, which element to insert it before/after and i dunno what the last one is
10:29 PM rue_mohr: I think I remmeber you working on it over a few weeks
10:29 PM Tom_L: yeah it kept getting better
10:30 PM Tom_L: it generates 1 thread then copies it however many threads you want
10:30 PM Tom_L: adding the lead in lead out moves
10:30 PM Tom_L: depending whether it's internal or external thread
10:31 PM rue_mohr: wait I dont remember watching the video
10:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent1.jpg
10:32 PM Tom_L: see how the leadin/out change depending on the thread type?
10:32 PM rue_mohr: oh you want from the bottom up
10:32 PM Tom_L: on internal yes
10:32 PM Tom_L: top down on external
10:32 PM Tom_L: so you can climb cut
10:32 PM rue_mohr: hows the new motor lookin?
10:32 PM Tom_L: great
10:32 PM Tom_L: i don't have to worry about it anymore
10:33 PM Tom_L: it's not 'perfect' but it does real well
10:33 PM Tom_L: takes a bit sometimes for the pid to keep up
10:33 PM Tom_L: but much better than the sherline
10:33 PM rue_mohr: yea
10:34 PM Tom_L: i don't really wanna go in the vfd and fiddle with their settings
10:34 PM rue_mohr: I'm gonna have to change the spingle arrangement on my OLD machine
10:34 PM rue_mohr: the chuck is on the motor shaft
10:34 PM Tom_L: yeah that's not ideal
10:34 PM rue_mohr: and the screws that hold the motor together are starting to give out
10:34 PM Tom_L: i'm very pleased with those larger belts i got
10:35 PM rue_mohr: as its a clam shell motor, those screws are kinda important
10:35 PM Tom_L: yep
10:35 PM Tom_L: i think i can run about anything on it now within reason
10:36 PM rue_mohr: steel?
10:36 PM Tom_L: nothing exotic like inconel or such
10:36 PM Tom_L: pretty sure if i run it slow yes
10:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Czech_part.jpg
10:37 PM Tom_L: it did that ok
10:38 PM Tom_L: that was 5/16 plate
10:43 PM rue_mohr: ah yes
10:43 PM rue_mohr: that was for the piano
10:53 PM rue_mohr: :/ there is a hole in the boiler firebox
10:53 PM rue_mohr: it was NOT designed to have to last this long
10:54 PM rue_mohr: and the exchanger duct is done too
10:54 PM Tom_L: :/
10:55 PM Tom_L: too bad you can't make it from SS
10:56 PM rue_mohr: its not supposed to have to last
10:56 PM rue_mohr: I'm supposed to have built a new house by now
10:56 PM Tom_L: is it your main heat source now?
10:56 PM rue_mohr: nope
10:56 PM rue_mohr: its not anything
10:56 PM Tom_L: i thought you were using it
10:56 PM rue_mohr: the rad sprung a leak 2 yaear ago and I'v not replaced it
10:57 PM rue_mohr: the most common rad at the time cant be found anywhere now
10:57 PM Tom_L: figures
10:57 PM rue_mohr: I got new things to make in-duct heaters, but unless I can make U pipes for them, they will cost more to build than the heat they would ever save me
10:58 PM rue_mohr: at $300/mo in winter
10:58 PM Tom_L: mmm
10:58 PM Tom_L: mine is generally about half that
10:58 PM Tom_L: summer or winter
10:58 PM rue_mohr: I got some stuff to try to make U pipes, but cant do it yet
10:58 PM Tom_L: elect / gas
10:59 PM Tom_L: copper?
10:59 PM rue_mohr: the gas is about $20/mo in summer
10:59 PM rue_mohr: yea
10:59 PM Tom_L: i duno what you need
10:59 PM rue_mohr: really tight bend
10:59 PM Tom_L: fill with water and pinch the ends
10:59 PM Tom_L: you can bend it fine
10:59 PM rue_mohr: I was going to use sand
10:59 PM Tom_L: that's how i did the coil for the sherline
10:59 PM rue_mohr: I borrowed a pipe flarer-
11:00 PM Tom_L: how big?
11:00 PM rue_mohr: 1/2 pipe
11:00 PM Tom_L: hmm
11:00 PM rue_mohr: and its got to have like a 3/4 gap on the inside of the bend
11:00 PM Tom_L: coil or hardened straight water pipe?
11:00 PM rue_mohr: I'll show you the module
11:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler1.jpg
11:02 PM Tom_L: full of water
11:02 PM Tom_L: doubt you can bend 1/2" that tight though
11:04 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1180676.jpg
11:04 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1180677.jpg
11:04 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1180678.jpg
11:04 PM rue_mohr: someone did
11:04 PM Tom_L: no, those are cast that way
11:04 PM rue_mohr: had a left over peice of duct from the house, so thats a prototype install
11:04 PM rue_mohr: cast!?
11:05 PM rue_mohr: CAST?????
11:05 PM Tom_L: extruded or however they make copper fittings
11:05 PM Tom_L: the point is, they were made that way
11:05 PM Tom_L: i bet you can buy them
11:05 PM Tom_L: ac shop
11:06 PM Tom_L: those are pre'made fittings
11:07 PM rue_mohr: they would cost too much and like I say, hours of explaining frustrate me
11:07 PM rue_mohr: I need like 110 of them
11:07 PM rue_mohr: if they only want like $15 ea...
11:08 PM Tom_L: https://www.amazon.com/Return-Bend-Wrot-Copper/dp/B0078S33VU
11:08 PM Tom_L: there you go
11:08 PM rue_mohr: at $300/mo it would break even at how many years?
11:09 PM rue_mohr: no price
11:09 PM rue_mohr: oh there from ~$14ea
11:09 PM rue_mohr: so $1540
11:09 PM Tom_L: https://www.alibaba.com/showroom/copper-180-degree-elbow.html
11:10 PM rue_mohr: I turn on the heat for about 3 months a year, thats 5 months worth of heating bills, so payoff in 2 years
11:10 PM Tom_L: find what you need there
11:10 PM rue_mohr: oo actually thats better
11:11 PM Tom_L: first one was just to see what you needed
11:11 PM Tom_L: now we find a price
11:11 PM rue_mohr: didn't think of ali
11:11 PM rue_mohr: they probably want ~$50 in shipping
11:12 PM rue_mohr: so ~$160
11:12 PM rue_mohr: much better payoff time
11:12 PM Tom_L: may not be copper but they're copper color :)
11:13 PM rue_mohr: its ok, I just have water to run thru them
11:13 PM Tom_L: but that's alot better option now
11:14 PM rue_mohr: indeed
11:14 PM rue_mohr: I need to carefully measure my gap
11:15 PM Tom_L: yes
11:17 PM Tom_L: looks like they're metric
11:17 PM Tom_L: at least the one i'm looking at
11:17 PM Tom_L: https://www.alibaba.com/product-detail/180-Degree-Copper-elbow-Copper-U_62211859475.html?spm=a2700.7724857.0.0.28ca1b19qxZve8
11:18 PM Tom_L: forged
11:18 PM Tom_L: that's what i was trying to come up with
11:18 PM Tom_L: not cast
11:20 PM Tom_L: you have any local wholesale AC supplies nearby?
11:20 PM Tom_L: at least you could physically see the center distance etc
11:23 PM Tom_L: https://catalog.nibco.com/viewitems/wrot-copper-pressure-fittings/return-bend-c-x-c-wrot-638
11:23 PM rue_mohr: they always express everything in metric
11:23 PM Tom_L: i know nibco makes alot of that stuff but i'm sure they'd be higher
11:23 PM rue_mohr: no AC supplies no
11:23 PM rue_mohr: and I would be lucky if they only wanted $13 ea
11:24 PM rue_mohr: I'll get the data tommorow and compare things from china
11:24 PM rue_mohr: if I just replace the house...
11:24 PM Tom_L: if i had to guess, they're probably fairly standard
11:24 PM rue_mohr: those modules were made prolly over 40 years ago
11:25 PM rue_mohr: their fine, but yea
11:25 PM Tom_L: that's the good thing about standards
11:26 PM rue_mohr: I was just thinking earlier today that in dec I was given a heap of copper stuff, I should go thru it
11:26 PM rue_mohr: wont be U pipes, but I'd still like to try to bend some
11:26 PM Tom_L: all that stuff is silver soldered
11:26 PM Tom_L: acy/oxy to undo it
11:26 PM rue_mohr: yea I can go standard solder
11:26 PM rue_mohr: just water
11:27 PM Tom_L: i know but if you're trying to salvage some of it...
11:28 PM rue_mohr: hmm says I have 28 modules
11:28 PM rue_mohr: that need 11 links ea
11:28 PM rue_mohr: 308 8-|
11:29 PM Tom_L: alot of leaks :)
11:29 PM rue_mohr: is hoplessness still an option?
11:29 PM Tom_L: do they all need ends?
11:29 PM rue_mohr: maybe those numebers are out
11:29 PM rue_mohr: yea, the orig was a 10' long one that got chopped up
11:29 PM Tom_L: k
11:30 PM rue_mohr: there is another one, from the sounds of it maybe I'm supposed to chop it up too
11:33 PM Tom_L: k, i'm goin to sleep
11:33 PM rue_mohr: night
11:33 PM rue_mohr: tahnks
11:33 PM * Tom_L nods
11:38 PM rue_mohr: https://www.steelfire.com/products/sku/HTC
11:38 PM rue_mohr: that will be easy
11:39 PM rue_mohr: if I want, I should even be able to buy one from them
11:39 PM rue_mohr: oh I'd have to redo the account
11:39 PM rue_mohr: their shipping was awefull and it expired
11:41 PM Tom_L: what's your budget for this test rig?
11:42 PM rue_mohr: not as high as it should be
11:42 PM rue_mohr: the other fire company keeps screwing up their customers
11:43 PM Tom_L: are they just getting into testing fire equipment?
11:43 PM rue_mohr: so more and more people come to us
11:43 PM rue_mohr: but the volume still isn't enough to get the full shazam
11:43 PM Tom_L: i bet that's what those guys near me do / did
11:44 PM rue_mohr: well, right now we have a guy come from FAR AWAY monthly to do the internal service on the exitinguishers
11:44 PM rue_mohr: but he cant do the hydro tests in his portable van
11:44 PM rue_mohr: so he takes them back
11:44 PM rue_mohr: they take 2-3 months to get done
11:44 PM Tom_L: how many different fittings are there?
11:44 PM rue_mohr: lots, but all the rest are simple external thread
11:44 PM rue_mohr: I can do them up no problem
11:45 PM rue_mohr: THAT one is the snag
11:45 PM rue_mohr: even if I blow an external thread, the setup is easy enough to just redo
11:46 PM rue_mohr: I bought a test pump
11:46 PM rue_mohr: *second one*
11:46 PM rue_mohr: the first was a $$$$$ pressure washer pump, modified
11:46 PM rue_mohr: SOMEONE STOLE IT
11:46 PM Tom_L: hand pump?
11:47 PM rue_mohr: so I have a hand pump this time
11:47 PM Tom_L: i had one of those porta paks
11:47 PM Tom_L: i gave it to some guy cause i never used it
11:47 PM rue_mohr: I have a nice simple job on a dock testing their fire pipes that will pay (I think) for the pump
11:48 PM rue_mohr: which is good, cause I dont know were we are at doing tanks
11:48 PM Tom_L: i always try to find ways for my toys to pay for themselves
11:48 PM rue_mohr: the guy who comes from far away is showing signs he doesn't want to do it much longer
11:48 PM rue_mohr: indeed
11:48 PM Tom_L: do you need certifications for testing them?
11:48 PM rue_mohr: yes and no
11:49 PM rue_mohr: supposedly the DOT has to auth tank tests
11:49 PM rue_mohr: *but* if they aren't used for transport it looks like there isn't anyone
11:49 PM Tom_L: do they stamp dates on the tank like they do oxy etc tanks?
11:49 PM rue_mohr: no
11:49 PM rue_mohr: there is just a paper collar
11:49 PM rue_mohr: well, and a sticker
11:50 PM rue_mohr: the sticker says what you tested it to and when
11:50 PM rue_mohr: the collar just says when it was last opened
11:50 PM Tom_L: do they replace the content or just stir it up?
11:50 PM rue_mohr: the ones I'm doing are just water
11:51 PM rue_mohr: there IS a kitchen one to be done, I'm gonna get the other guy to do it
11:51 PM rue_mohr: they kitchen agent is sold in 2-tank volumes
11:51 PM rue_mohr: its so rare we ever have to do one that I'm not eager to go there
11:51 PM rue_mohr: even these water ones are kinda rare
11:52 PM rue_mohr: the ABC ones are powder, it just get removed and put back
11:52 PM rue_mohr: https://www.uline.ca/Product/Detail/S-15640/Fire-Protection/Fire-Extinguisher-Class-K-6-L
11:52 PM rue_mohr: kitchen ones
11:52 PM rue_mohr: (that one has *that* thread)
11:53 PM Tom_L: i wondered about that
11:53 PM rue_mohr: https://www.uline.ca/BL_990/ABC-Fire-Extinguishers <-- ABC (poweder)
11:53 PM Tom_L: i didn't realize uline sold those
11:54 PM rue_mohr: https://www.firesafetysupply.net/shop/amerex-240-2-5-gallon-water-class-a-fire-extinguisher/ <-- class A (just water)
11:54 PM rue_mohr: oh and its *that* thread again
11:55 PM rue_mohr: I think that the places that do it are aggragating
11:55 PM rue_mohr: which explains why nobody has the adatpers
11:55 PM rue_mohr: I'm in the middle of nowhere, so I have no big shop to send them to
11:55 PM Tom_L: both amerex
11:55 PM rue_mohr: oh, hmm
11:56 PM rue_mohr: I should drag the test pump home and do my 1979 compressor tank
11:57 PM Tom_L: so they're not _just_ electricians
11:59 PM rue_mohr: well, that was the angle we started the fire protection thing at
11:59 PM rue_mohr: but there was only one other local (who isn't local) company doing fire testing, and people were getting angry with them
