12:00 AM rue_shop4: the tool body is 3/8"
12:09 AM rue_shop4: I'm confused
12:09 AM rue_shop4: it would explain why the holder for those tools only went down to 16mm
12:09 AM Tom_L: https://www.kmstools.com/magnum-wgnr-carbide-insert.html
12:09 AM rue_shop4: mine are triangle tho
12:09 AM Tom_L: it appears yours are inch
12:09 AM Tom_L: there are different sizes of inch T cutters
12:09 AM Tom_L: you need to figure out what geometry you have
12:09 AM rue_shop4: well I'm sure as the hell not paying $10 for a bit I'm gonna ruin in a 1 hour turning sesson
12:09 AM Tom_L: is there a relief angle?
12:09 AM Tom_L: TNMG are common
12:09 AM rue_shop4: 1 sec
12:09 AM Tom_L: no, the G is round
12:10 AM Tom_L: there are more than one standard for sure
12:10 AM rue_mohr: ugh
12:11 AM Tom_L: draw one on paper with a sharp pencil and measure the inscribed circle and cut length
12:11 AM Tom_L: see what you get
12:12 AM Tom_L: hole center of holder to the back edge will give you the inscribed radius
12:13 AM rue_shop4: holding a 1/4" drill over it says yup
12:13 AM rue_shop4: so its 1/4' insribed
12:13 AM Tom_L: touches all 3 edges?
12:13 AM Tom_L: ok
12:13 AM Tom_L: small
12:13 AM rue_shop4: how are the chineese measuring it?
12:13 AM rue_shop4: hmm
12:13 AM Tom_L: cut edge i think
12:14 AM Tom_L: 16 being the 16mm cut length
12:14 AM rue_shop4: cad...
12:14 AM Tom_L: 03 being the insert thickness
12:14 AM Tom_L: your inserts are small
12:15 AM Tom_L: compared to other lathe inserts
12:15 AM rue_shop4: hm about 11mm
12:15 AM Tom_L: iirc my buds used square
12:15 AM Tom_L: but i don't think yours are metric
12:15 AM rue_shop4: no
12:16 AM Tom_L: so don't use those charts
12:16 AM rue_shop4: but, its about 11mm
12:16 AM Tom_L: ok
12:16 AM rue_shop4: well, I only have to ...
12:16 AM rue_shop4: no that wont work
12:16 AM Tom_L: inch go off the inscribed circle i believe
12:16 AM rue_shop4: I cant just grind the edge back, there would be no support
12:16 AM rue_shop4: huh
12:16 AM rue_shop4: I did not see smaller stuff from china
12:16 AM Tom_L: don't grind anything. figure out what one you need!
12:16 AM rue_shop4: "16" was the smallest
12:17 AM Tom_L: and you may not
12:17 AM rue_shop4: hmm
12:17 AM rue_shop4: they also use the diamonds for their tools, not the triangles
12:17 AM rue_shop4: <>
12:19 AM Tom_L: depends on the holder, yes
12:20 AM rue_shop1: but like, they basically dont use the triangles for the left/right/center holders
12:21 AM Tom_L: TNMG are fairly common unless you need a relief angle
12:21 AM rue_shop1: I like a relief angle
12:21 AM rue_shop1: I was cutting a stainless bolt today
12:22 AM Tom_L: how big is the center hole countersink?
12:22 AM Tom_L: look at chart4 on my page
12:23 AM Tom_L: H?
12:23 AM Tom_L: W
12:23 AM Tom_L: T
12:23 AM Tom_L: B
12:23 AM rue_shop1: http://www.mitsubishicarbide.com/en/technical_information/tec_turning_tools/tec_turning_insert/tec_turning_guide/tec_turning_identification
12:23 AM rue_shop1: that page?
12:23 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/inserts/Carbide_inserts.html
12:24 AM Tom_L: we're looking for inch
12:24 AM Tom_L: not metric
12:24 AM Tom_L: i think
12:24 AM rue_shop1: its countersunk
12:25 AM Tom_L: what angle?
12:26 AM Tom_L: how thick is the insert?
12:26 AM rue_shop1: ... the screw is a T8...
12:26 AM Tom_L: how thick is the insert?
12:27 AM rue_shop1: 0.1inches
12:28 AM rue_shop1: I thnk its 70-90
12:28 AM Tom_L: TPMH2xX
12:29 AM Tom_L: but that's a wag
12:29 AM Tom_L: still dunno if it's inch or metric
12:29 AM rue_shop1: seems steeper than 60
12:29 AM rue_shop1: its 0.1inches thick
12:29 AM rue_shop1: but uses a T8 screw
12:29 AM Tom_L: that thickness doesn't match the inch chart
12:29 AM rue_shop1: oh but that fits
12:30 AM Tom_L: ISO T2 thickness
12:30 AM Tom_L: or maybe ANSI 3?
12:30 AM Tom_L: i dunno
12:31 AM rue_shop1: 0.102
12:31 AM rue_shop1: huh
12:32 AM Tom_L: TPMH
12:34 AM Tom_L: TPMH-11-02-01
12:34 AM Tom_L: TPMH-11-02-01-R-LP
12:35 AM Tom_L: for example
12:35 AM Tom_L: try using the mitsu chart
12:37 AM rue_shop1: I"m gonna give up till I do more digging from china
12:37 AM rue_shop1: all this will lead to bits I cant afford
12:37 AM Tom_L: yep
12:37 AM Tom_L: you gotta know what you got
12:38 AM Tom_L: there are thousands of inserts
12:38 AM rue_shop1: I kinda wonder what magnum did
12:38 AM Tom_L: the sherline are hard to pin down too
12:38 AM Tom_L: could be special.. i dunno
12:39 AM rue_shop1: I kinda thought these bits were more standardized
12:39 AM Tom_L: you just gotta narrow it down a digit at a time until you find the right insert
12:40 AM Tom_L: we know it starts with T
12:40 AM Tom_L: on just about any chart
12:40 AM rue_shop1: :)
12:40 AM rue_shop1: the holders aren't super complex either
12:41 AM Tom_L: but each digit describes a part of the cutter
12:41 AM Tom_L: including the hole and shape of the hole
12:41 AM Tom_L: it _can_ turn into a real pita
12:46 AM Tom_L: gnite
05:22 AM Tom_L: morning
10:39 AM Tom_L: .
11:07 AM rue_mohr: I'm up
11:07 AM rue_mohr: ugh
11:07 AM rue_mohr: why is it so early
11:08 AM rue_mohr: did I tell you the 2nd attempt to build that BGA CPLD board seems to ahve worked?
11:09 AM Tom_L: i may have seen that
11:09 AM Tom_L: i've slept since then though
11:12 AM rue_mohr: its a cool little baord
11:12 AM Tom_L: oh the one you solder the bga to?
11:12 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230306.jpg
11:13 AM rue_mohr: yea, dont seem to have any shorts this time
11:13 AM rue_mohr: or opens
11:13 AM Tom_L: nice
11:13 AM rue_mohr: 3.3V regualtor, properly labeled pins
11:13 AM rue_mohr: buttons and leds that aren't overlapped onto pins
11:14 AM rue_mohr: ooo windy day
11:14 AM rue_mohr: the only thing I'd like to have added were high speed differential pairs
11:15 AM Tom_L: my cnc daughter board has several of those
11:15 AM rue_mohr: :) I just need a project now
11:15 AM rue_mohr: 6x8 io
11:16 AM rue_mohr: wow actually its really windy
11:18 AM rue_mohr: I wonder if I could pull of a minimal cpu
11:18 AM rue_mohr: I dont think so
12:03 PM rue_mohr: huh
12:04 PM rue_mohr: I could put the 1 inch square cpu on my cpld with 1 io to spare
12:04 PM rue_mohr: which is funny cause my cpld board is a lot larger than that
12:16 PM Tom_L: doing up a sketch for A9 & A10 for your docs
12:18 PM rue_mohr: this morning I'm falling into this whole 1 inch cpu thing
12:18 PM rue_mohr: https://cdn.hackaday.io/files/1612516898962784/NAC1840.pdf
12:18 PM rue_mohr: fascinatingly simple
12:26 PM rue_mohr: I think I find it so, because loooong ago, I invisioned a FSM that was kinda a mix of two state machines, one of them rom based and the other ram based
12:26 PM rue_mohr: but I didn't know how to mix it
12:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/B2_proto/
12:59 PM Tom_L: A9_A, A10_A
01:00 PM Tom_L: any others?
01:00 PM Tom_L: i bent the tabs too btw :)
01:17 PM rue_mohr: what did it take to bend them?
01:18 PM Tom_L: pliers
01:18 PM Tom_L: :):)
01:18 PM rue_mohr: ? there is an interesting rouge line on A9
01:19 PM rue_mohr: doesn't matter, but its... curious
01:19 PM Tom_L: workable?
01:19 PM rue_mohr: yes
01:19 PM Tom_L: maybe i can fix it
01:19 PM rue_mohr: its ok I can just select and delete it
01:19 PM rue_mohr: but I wonder what generated it
01:20 PM Tom_L: phone
01:20 PM rue_mohr: there was a fair amount of foofing to seperate those eh?
01:21 PM rue_mohr: I imagine you discovered I set them to account for the saw blade width?
01:22 PM Tom_L: no i just removed the 'saw' space
01:22 PM Tom_L: not too difficult
01:22 PM Tom_L: they look workable then?
01:22 PM rue_mohr: sketch level or 3d level?
01:23 PM Tom_L: sketch
01:23 PM rue_mohr: yea, they are great!
01:23 PM Tom_L: took a bit to get them oriented the way you want but i figured that out
01:23 PM rue_mohr: didn't you say is was a 'standard view'?
01:24 PM Tom_L: yeah but i did those in catia and exported iges to solidworks and they came in on an odd plane
01:24 PM rue_mohr: huh
01:24 PM rue_mohr: that happens with some of the 3d printer stuff two
01:24 PM rue_mohr: one of them uses a different xyz orientation
01:24 PM Tom_L: i didn't bother fixing that just figured out how to get the dxf right
01:25 PM Tom_L: any others you want?
01:25 PM Tom_L: you can move these around and put them where you want?
01:26 PM rue_mohr: yes, I can compose
01:26 PM Tom_L: ok
01:27 PM rue_mohr: let me see what I have here
01:28 PM rue_mohr: A10.dxf
01:28 PM rue_mohr: A3.dxf
01:28 PM rue_mohr: A8.dxf
01:28 PM rue_mohr: A9.dxf
01:28 PM rue_mohr: B2.dxf
01:28 PM rue_mohr: huh there is no 12
01:29 PM rue_mohr: didn't you start with that tho?
01:30 PM rue_mohr: huh
01:30 PM Tom_L: it's on the server
01:30 PM Tom_L: A12_A
01:30 PM rue_mohr: it seems to me, that B2 should work as A2... hmmm
01:31 PM Tom_L: yeah you can probably get by with that but i can make an A2 if you want
01:31 PM rue_mohr: just as a design thing
01:31 PM rue_mohr: doesn't it seem that it should work for that?
01:31 PM rue_mohr: the pin is in a different spot tho
01:31 PM rue_mohr: hmmm
01:31 PM Tom_L: it's your call
01:32 PM Tom_L: i can but i'm in 32bit doing something else right now
01:32 PM rue_mohr: yea, I'm just thinking
01:32 PM Tom_L: rebooting..
01:32 PM rue_mohr: hmm, can we change the view on A12 when you have a chance?
01:33 PM Tom_L: as we speak
01:33 PM Tom_L: like the others?
01:33 PM rue_mohr: were not gonna wear out your reset button are we?
01:33 PM Tom_L: bios
01:33 PM rue_mohr: yea, I cant manipulate that into the right view...
01:33 PM rue_mohr: the matching view...
01:34 PM rue_mohr: I should try modeling a pin ...
01:34 PM rue_mohr: see if I can render it like that
01:34 PM rue_mohr: then I need to go strip down printers!!!
01:36 PM Tom_L: it wants to come in backwards
01:36 PM rue_mohr: its... not on the correct side on my drawing is it...
01:37 PM rue_mohr: http://www.ruemohr.org/exploded.jpg
01:37 PM rue_mohr: and it looks backwards in my drawing
01:37 PM rue_mohr: blob as it is
01:39 PM Tom_L: see if that's better
01:42 PM Tom_L: there's an _A, _B and _BOTH
01:42 PM Tom_L: pick which one you want
01:43 PM rue_mohr: :S this isn't working
01:43 PM rue_mohr: (my pin)
01:44 PM rue_mohr: ??!?! power wink
01:44 PM rue_mohr: again?
01:44 PM rue_mohr: wtf
01:45 PM rue_mohr: hmm, that view still doesn't seem right
01:45 PM rue_mohr: am I just out?
01:45 PM Tom_L: it mounts sideways
01:46 PM Tom_L: but i'm not sure what view or if i can flip it
01:46 PM rue_mohr: oh, hah, part of whats throwing me is the missing slot!
01:46 PM rue_mohr: I cant generate views like that from 3d models
01:47 PM rue_mohr: I thought I saw something a while ago in a program that could , but it cant
01:52 PM rue_mohr: good thing I can just draw the pin by hand :)
01:52 PM rue_mohr: (in cad)
01:55 PM Tom_L: heh
01:55 PM Tom_L: is A12 ok now?
01:56 PM rue_mohr: the view doesn't seem right... it could use a slot too, I can do one up and send you an stl if you'd like
01:57 PM rue_mohr: almost 12 tho, I should go get the yard stuff done :( its a horrid day out
01:58 PM Tom_L: if you want. i keep booting back and forth :)
01:58 PM Tom_L: almost done in 32bit
01:58 PM Tom_L: had to update a kids resume :)
02:00 PM rue_mohr: dont put any priority on this for me
02:02 PM rue_mohr: oh gee, I need to make sure I got both bills out
02:03 PM rue_mohr: I'm gonna be on yard things till I'm too wet and cold to continue
02:06 PM Tom_L: ok now what was i supposed to fix?
02:43 PM Tom_L: ok all caught up.. time to play
03:03 PM rue_shop4: I was gonna slot that for ya
03:03 PM rue_shop4: see if we can get a mating orientation to A9
03:08 PM Tom_L: take a look at those A12.. i dunno if they're any different
03:09 PM Tom_L: slot was easy, orientation not as much
03:10 PM Tom_L: the slot on that model isn't accurate so just use it for documents
03:10 PM Tom_L: i did that all in my cad cam which doesn't have an actual model
03:12 PM Tom_L: i'm not quite sure what orientation you need for it
03:16 PM rue_shop4: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/B2_proto/
03:17 PM Tom_L: did i upload ones with slots?
03:17 PM Tom_L: damn i can't keep track....
03:17 PM rue_shop4: the latch is on the left side of the sprayer...
03:17 PM rue_shop4: I think if I rotate the A view a bit clockwise ...
03:17 PM * rue_shop4 squints
03:18 PM Tom_L: you can do that?
03:18 PM rue_shop4: yea
03:18 PM Tom_L: the standard views just aren't right between the 2
03:19 PM rue_shop4: :)
03:20 PM Tom_L: you have the trigger?
03:20 PM Tom_L: i forgot what that was... A3?
03:20 PM rue_shop4: I found a tvio on the deck, it needed a new cap
03:20 PM Tom_L: oh i did an A3
03:20 PM rue_shop4: I think I can use it as a long video recorder
03:21 PM rue_shop4: wonder if I can get the videos off after
03:23 PM Tom_L: i uploaded an A2 just now too
03:24 PM Tom_L: i don't have an A7 model
03:25 PM Tom_L: it's plastic
03:25 PM Tom_L: wait.. yes i do
03:26 PM Tom_L: it's no good though
03:27 PM Tom_L: that was what i used to make B2
05:13 PM rue_mohr: if I just use the B2 graphic I'm sure 0% will notice
05:22 PM Tom_L: fine by me
05:23 PM Tom_L: out cleaning the mower filter etc and making sure it would start
05:24 PM Tom_L: did better than i expected
05:29 PM rue_shop4: I got one printer stripped down
05:32 PM Tom_L: heh
05:32 PM Tom_L: 100 to go?
05:37 PM rue_mohr: ugh
08:45 PM rue_mohr: most of the way thru a 2nd printer
08:45 PM rue_mohr: I think its a colour I was supposed to fix
08:46 PM Tom_L: i found one in the attic while looking at the steam tank i nearly tossed in the trash
08:46 PM rue_mohr: inkjet or lase?
08:46 PM Tom_L: ink
08:46 PM rue_mohr: these are all laser
08:46 PM Tom_L: oh
08:46 PM Tom_L: there's a laserjet in the basement nobody uses
08:49 PM rue_mohr: I think there are still 6 or 7 left on the deck
08:49 PM Tom_L: ppl keep sending em your way?
08:49 PM rue_mohr: every time I do this the hospital rings me up and says they have the next batch ready
08:53 PM rue_mohr: lets count
08:53 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230337.jpg
08:54 PM rue_mohr: 2...
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230338.jpg
08:54 PM rue_mohr: 3,4,5
08:54 PM Tom_L: quite a pile
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230339.jpg
08:54 PM rue_mohr: 6...
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230340.jpg
08:54 PM rue_mohr: 7,8
08:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230341.jpg
08:54 PM rue_mohr: 9
08:55 PM rue_mohr: -- 9 printers --
08:55 PM Tom_L: no wonder you complain about room all the time
08:55 PM rue_mohr: I'v stripped down 3 in the last few days eh?
08:55 PM rue_mohr: yea
08:55 PM rue_mohr: see the pile of metal in the last image
08:55 PM rue_mohr: that was the printer I just stripped
09:51 PM rue_mohr: the pile of garbage plastic is becomming a problem
09:51 PM rue_mohr: its larger than the garbage can right now
09:51 PM rue_mohr: thats just 3 printers
09:55 PM Tom_L: melt into printer string?
09:55 PM Tom_L: wrong kind probably
09:55 PM rue_mohr: too bad I dont have a mold to cast handles!
09:55 PM Tom_L: would be some odd colors
09:56 PM rue_mohr: would probably be really heavy tho
09:56 PM rue_mohr: they seem to like to have them a bit unique
09:56 PM Tom_L: :)
09:56 PM rue_mohr: we kinda mix the colours to that affect
09:56 PM Tom_L: i'm kinda partial to that purple
09:56 PM rue_mohr: looks better irl
09:57 PM rue_mohr: oh wait, did I send you a purple one?
09:57 PM Tom_L: no
09:57 PM Tom_L: yellow?
09:57 PM Tom_L: i forget
09:57 PM rue_mohr: maybe
09:57 PM rue_mohr: try to keep them bright to find easy
09:57 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Can_holder_assy.jpg
09:57 PM Tom_L: you must go thru alot of PLA
09:58 PM rue_mohr: I was calculating
09:58 PM rue_mohr: if all goes ok, we get 16 handles to a roll
09:58 PM rue_mohr: roll is $50
09:58 PM Tom_L: cost?
09:58 PM Tom_L: $$ for a plastic part
09:58 PM rue_mohr: so, all in all not too bad
09:59 PM rue_mohr: its interesting learning how costs go for mass production
09:59 PM rue_mohr: 16 $3 parts and...
09:59 PM rue_mohr: we usually lose about 3 to errors tho
10:00 PM Tom_L: if you weren't doing the machining yourself you would lose money on them
10:00 PM rue_mohr: ?
10:00 PM rue_mohr: oh, yea
10:00 PM Tom_L: if you paid a professional shop to machine the parts
10:00 PM rue_mohr: unless volumes were like 10k
10:00 PM Tom_L: call your china supplier :)
10:00 PM rue_mohr: hah
10:01 PM rue_mohr: slip them the design and just resell them with markup
10:02 PM Tom_L: but really the machine time isn't that much if you were doing it that way
10:02 PM Tom_L: takes you longer
10:03 PM Tom_L: takes me longer due to tool changes
10:03 PM rue_mohr: the labor is still the major cost
10:03 PM rue_mohr: I was reminded making those 6 that there is a LOT of work to go from nothing to sprayer
10:03 PM Tom_L: yeah
10:04 PM rue_mohr: we have two books
10:04 PM Tom_L: you hammer the tabs over?
10:04 PM rue_mohr: one is instructions to make the parts
10:04 PM rue_mohr: the other is assembly of the parts into a sprayer
10:04 PM rue_mohr: yes, I have a former that goes in the vise and I hammer them over
10:04 PM rue_mohr: I was pondering a press jig
10:04 PM Tom_L: press the tabs
10:04 PM Tom_L: i would
10:05 PM Tom_L: alot quicker and more uniform
10:05 PM rue_mohr: takes almost no time to just hammer them
10:05 PM rue_mohr: the press is a hand pump
10:05 PM Tom_L: yeah
10:05 PM Tom_L: get a big arbor press
10:05 PM Tom_L: or a cheater bar :)
10:05 PM rue_mohr: hmm
10:05 PM rue_mohr: didn't think of the arbour press
10:06 PM Tom_L: that would be quick
10:06 PM Tom_L: i broached my pulley with the drill press because that's all i had
10:06 PM rue_mohr: the major slowdown doing it by hand is that the soft jaws aren't fixed in
10:06 PM Tom_L: it was pushing it's limits
10:07 PM Tom_L: soft jaws?
10:07 PM Tom_L: oh for forming them?
10:07 PM rue_mohr: well, there is a former jig, and a soft jaw
10:07 PM rue_mohr: yea
10:07 PM Tom_L: show me
10:07 PM rue_mohr: you put it in and bump the one over
10:07 PM rue_mohr: ....
10:07 PM rue_mohr: their all bent
10:08 PM Tom_L: the form
10:08 PM rue_mohr: hmm
10:08 PM rue_mohr: maybe I have a defiective one thats not bent yet
10:08 PM Tom_L: all i need to see is the form
10:09 PM rue_mohr: oh I had a pic
10:09 PM Tom_L: i know what the parts look like :)
10:09 PM Tom_L: i may have seen it but i forget
10:11 PM rue_mohr: looking
10:11 PM rue_mohr: its 1/2" plate with some guide pins and radius'd corners
10:11 PM rue_mohr: looking
10:11 PM rue_mohr: ...
10:12 PM Tom_L: i'd make them so the top slides down guided with some pins with return springs
10:12 PM Tom_L: don't think i have a chunk of steel big enough
10:13 PM Tom_L: the bottom half could be aluminum since nothing slides on it
10:14 PM rue_mohr: the hold-down foot for the top would be the hard part
10:15 PM Tom_L: my bud used to make punch dies for sheet aluminum
10:15 PM Tom_L: i programmed a few of them
10:15 PM Tom_L: hydropress would be the other method
10:16 PM Tom_L: you'd only need the bottom for that
10:16 PM Tom_L: with a 2-3deg undercut for springback
10:16 PM rue_mohr: do you think that step could be pressed in?
10:16 PM rue_mohr: A9/10
10:16 PM Tom_L: which?
10:17 PM Tom_L: press the tabs down?
10:17 PM rue_mohr: the step that holds the can
10:17 PM Tom_L: no
10:17 PM rue_mohr: I was wondering if the whole thing could be pressed
10:17 PM Tom_L: you'd need a hefty press
10:18 PM rue_mohr: aren't they usually 100-200 tonnes?
10:18 PM Tom_L: once and done too... not a hand pump
10:18 PM Tom_L: it work hardens
10:18 PM rue_mohr: hmm
10:18 PM Tom_L: the coleman lanterns?
10:18 PM Tom_L: i worked in the shop that did the tanks
10:19 PM Tom_L: not hydraulic though
10:19 PM Tom_L: huge flywheel
10:19 PM rue_mohr: yep
10:19 PM rue_mohr: old castings?
10:19 PM rue_mohr: 3 stories high?
10:19 PM Tom_L: the machine shop was right next to the press and the solder line that brazed them together
10:20 PM rue_mohr: :)
10:20 PM Tom_L: no
10:20 PM Tom_L: it was some old junk
10:20 PM Tom_L: heavy
10:22 PM Tom_L: i heard stories about the flywheel cutting loose once and took out part of a wall
10:23 PM Tom_L: to stamp it you'd need 'O' material
10:23 PM Tom_L: fully annealed
10:24 PM Tom_L: they used sheet tin for those tanks
10:24 PM Tom_L: cut into circles then drawn

10:42 PM rue_mohr: sorry I posted those like 10 mins ago
10:47 PM rue_mohr: multi-stage draw?
10:48 PM Tom_L: it's been years...
10:48 PM Tom_L: the tanks were drawn in one punch
10:48 PM Tom_L: then the lip trimmed off
10:55 PM Tom_L: yeah i've seen that fixture before but forgot
11:21 PM rue_mohr: 2381
11:22 PM Tom_L: down?
11:22 PM Tom_L: i wonder how far apart a top piece would need to be to work on those tabs
11:22 PM rue_mohr: I dont know if its up or down, the digits seem different
11:22 PM Tom_L: you'd get more spring back that how you're doing it now
11:23 PM rue_mohr: after being beaten its pretty tight
11:24 PM Tom_L: i'll have to see what sort of steel i have and maybe play with one
11:24 PM rue_mohr: it could be alum
11:24 PM Tom_L: i don't have much on hand
11:24 PM Tom_L: not the top
11:24 PM Tom_L: i don't think
11:24 PM Tom_L: i think it would gauld up
11:24 PM Tom_L: the bottom could be
11:25 PM rue_mohr: I need to work out how to get you to assemble that sprayer :)
11:25 PM Tom_L: ?

11:26 PM Tom_L: dunno if there was chain or not
11:26 PM Tom_L: i don't remember off hand
11:26 PM Tom_L: i don't think so
11:26 PM rue_mohr: :( I hope so
11:26 PM Tom_L: i can check
11:26 PM rue_mohr: after all that stuff about casting them
11:26 PM rue_mohr: I still need to make a new ladel
11:26 PM rue_mohr: the chance didn't come up this weekend
11:27 PM Tom_L: yeah you did
11:27 PM rue_mohr: oh good
11:27 PM Tom_L: ahh the chain is too
11:28 PM Tom_L: i used one of my triggers though since it was already drilled
11:28 PM Tom_L: the cast ones look pretty darn good
11:28 PM rue_mohr: yea
11:28 PM rue_mohr: :)
11:28 PM rue_mohr: I didn't drill it?

11:34 PM Tom_L: i guess you bent them all...
11:36 PM Tom_L: man, i better get to sleep...
11:44 PM rue_mohr: I should see, I'm not sure what I used for the 18" sprayers, but I think they were already made by then
11:44 PM rue_mohr: I should be able to do up one this week
11:54 PM rue_mohr: gngiht
