#linuxcnc Logs

Jun 26 2019

01:02 AM pingufan: sync: When the existing system is doing what I need (and technical specs of my cnc mill aren't changing), I see no real need to replace the PC (except if the new linuxcnc would do things so significantly better in my not changed environment.
01:06 AM pingufan: Anyway...
02:34 AM Loetmichel: hmm... anyone has a recommodation for the cheapest working wire feed (MIG) welder that would do 3mm sheet aluminium on ebay?
02:35 AM Loetmichel: ... preferably with shipping to germany?
03:30 AM Loetmichel: *maaaan* What did i eat yesterday? You could remove paint with those farts today... ("its not so much the smell, its more the burning sensation in the eyes that bothers me!") :-(
04:20 AM XXCoder: Loetmichel: be glad you dont have my guts, lets just say that.
04:25 AM Loetmichel: *giggle* cowroker just came with our last 6mm two flute tungsten carbide mill bit... "is that still good? it cuts like shit!" $me dons the watchmakers specs (25x) and looks: nop, both edges are broken off... gimme a second... *grips leatehrman, folds out the diamonf file*.... mini-desk vise, *ziggiziggizig* *turns mill bit 180°* *ziggiziggizig* *ahhh!* $me: "now it will cut again." coworker:
04:25 AM Loetmichel: .oO
04:27 AM XXCoder: nice wish was that skilled lol
04:29 AM Loetmichel: pure practice. the first few 10 mill bits will be garbage afterwards. takes a while to get it right freehand ;) (and good magnifying glasses) ;)
04:31 AM XXCoder: lol ok
04:34 AM Loetmichel: i think coworker wasnt impressed with the fact that i could re-edge the bit... but that i did it on my desk freehand with a leatherman wave of all tools possible ;)
05:01 AM Tom_L: morning
05:02 AM XXCoder: yo
05:36 AM PL7icnc: hi it is HOT in Germany
05:37 AM PL7icnc: shoptemp did exeed 50C for the first time
05:37 AM PL7icnc: plasma cooling water is at 85deg
05:37 AM PL7icnc: cand even get one sheet cut withot refilling water to the level
05:39 AM XXCoder: ironic, right now, here is in 50f
05:39 AM XXCoder: cant do a system where it automically refills by float and such?
05:41 AM PL7icnc: i can but it is not needed as we change regulair (30min) per sheet
05:42 AM PL7icnc: XXCoder, where are you Sibiria
05:42 AM PL7icnc: Nowosibirsk
05:42 AM PL7icnc: im in SW germany
05:43 AM XXCoder: in at usa
05:44 AM PL7icnc: Sir it is so hard to connect to the Forum as of TLS-Handshake do you kow how to solve that on ubuntu
05:45 AM XXCoder: no idea, I dont use forum
05:49 AM jthornton: forum works for me...
05:49 AM jthornton: time to let the chickens out
06:00 AM Bushman: hi guys
06:01 AM Bushman: i was trying to install and use the "Probe screen V2" helper program but i've encountered some problems
06:01 AM Bushman: 12:17:12 Error: EOF in file:/home/cnc/linuxcnc/nc_files/HCP.ngc seeking o-word: o<xplus> from line: 0
06:02 AM Bushman: i keep getting that error. googling shows that i should remove all '%' from my nc files but i can't find any!
06:02 AM Bushman: anyone had a similar problem with subroutines?
06:03 AM jthornton: sure it says it can't find the subroutine
06:03 AM Bushman: yes, i've noticed
06:03 AM XXCoder: bush is there a empty line before %?
06:03 AM Bushman: XXCoder: no, there's no empty line and there's no %
06:03 AM XXCoder: ok
06:03 AM Bushman: i don't really know what's happening from the pythos side of things tho
06:04 AM Bushman: *python
06:04 AM Bushman: i just wanted to use a ready-made solution :(
06:04 AM Bushman: it looks nice, has all the features...
06:04 AM Bushman: just doesn't work with 2.7.14 for some reason
06:04 AM jthornton: are you trying to sell it?
06:05 AM Bushman: no, i'm trying to use it
06:05 AM jthornton: sounded like a salesman for a minute lol
06:05 AM jthornton: dunno what it is though
06:06 AM Bushman: lol
06:06 AM Bushman: i've made myself a probe...
06:06 AM Bushman: https://imgur.com/a/IUm710q
06:06 AM Bushman: but it's a bit hard to use it manually
06:07 AM jthornton: I just use the tried and true cradek probe routines
06:07 AM XXCoder: looks nice
06:08 AM Bushman: XXCoder: thanks. i've worked hard to make it as neat as i could.
06:08 AM jthornton: how do you center the probe to the spindle?
06:08 AM Bushman: jthornton: trial and error lol
06:08 AM Bushman: the caarbon stick and the ball with a shaft needs to be remade
06:09 AM Bushman: but i had no correct drill at the time
06:09 AM jthornton: http://gnipsel.com/linuxcnc/files/ngcgui-probe.zip
06:10 AM Bushman: i need to load each of them manually? or is there some GUI?
06:11 AM Bushman: looks like just the probing routines, right?
06:11 AM jthornton: as they are can be used with ngcgui
06:11 AM Bushman: ngcgui?
06:11 AM * Bushman googles
06:11 AM jthornton: yes they are the tried and true probing routines converted to be used with ngcgui
06:11 AM jthornton: don't google just look in the documents
06:13 AM Bushman: google pointed me to the right page in the docs :)
06:14 AM jthornton: just make sure your not reading the wrong version docs...
06:14 AM PL7icnc: Bushman, you might be need a debounce for it
06:14 AM Bushman: PL7icnc: not might, must lol
06:15 AM Bushman: it's noisy AF on closing :P
06:15 AM Bushman: plan is to construct a better version with electronics inside
06:15 AM Bushman: i'm still designing the schematic/PCB tho
06:16 AM PL7icnc: yes selfmade is cool but tricky a renishaw at 60USD is quite nice
06:17 AM Bushman: it's a hobby for me. i'd rather make something than buy
06:17 AM Bushman: if i can
06:17 AM PL7icnc: bushman here the plasmas are burning of atonn of water today no cooling at all
06:18 AM Bushman: unless it will be multiple times more expensive to make it than to buy it lo
06:18 AM Bushman: *lol
06:18 AM jthornton: more challenging to build than just buy...
06:19 AM Bushman: well, isn't that the purpose of a hobby? :P
06:19 AM PL7icnc: Mr Bushman id like to say sorry to you on all this OS and version confusion im alo in
06:19 AM Bushman: the best deffinition i've heard was "hobby: an activity that takes large ammounts of time and money" lol
06:19 AM Bushman: and since time = money and i have a lot of the first one...
06:20 AM PL7icnc: i run 10.04 2.5.4 on 2 plasmas behind me and like to update also but cand get things solved out
06:20 AM PL7icnc: and on 8hr workshift i cand even spare 2hr for renew system here as holiday is quite a big deal with all this garden accesouis
06:20 AM Bushman: PL7icnc: heh. i have 10.04 on one of my machines too
06:20 AM Bushman: it works fine
06:21 AM PL7icnc: yes thats the case never change a working system
06:21 AM Bushman: this is a new machine i'm building with a new PC and all...
06:21 AM Bushman: so i've downloaded the latest version
06:21 AM PL7icnc: i did finish the 5th plasma within 2weeks
06:21 AM Bushman: heeksCNC doesn't work here :(
06:21 AM PL7icnc: it is working on wheezy right now
06:21 AM Bushman: dxf2gcode doesn't work here either
06:22 AM PL7icnc: if you install opencascade heekscnc is quite nic to work with
06:22 AM PL7icnc: i use sheetcam ok i got a licence
06:23 AM PL7icnc: but at now 5 plasmas at full work its a must
06:23 AM Bushman: heekscad works but the CNC part won't compile cause of some lib not compiling (opencam i think)
06:23 AM PL7icnc: use the ppa
06:23 AM Bushman: and PPAs are not working for me and i don't know how to fix it either :(
06:23 AM PL7icnc: not selfcompiling
06:23 AM PL7icnc: ok no realy need to it
06:23 AM Bushman: i'd love to install from ppa, but it just doesn't work.
06:24 AM PL7icnc: DID you work with the free version of sheetcam
06:24 AM Bushman: maybe i could bounce the errors off you? maybe you'd know how to fix it?
06:24 AM Bushman: there's a free version!?
06:24 AM Bushman: i've heard about sheetcam long tme ago
06:24 AM PL7icnc: yes it gets 500 lines of code
06:24 AM Bushman: i see
06:25 AM Bushman: i think i'm starting to remember...
06:25 AM PL7icnc: https://www.sheetcam.com/Downloads/akp3fldwqh/SheetCam_setupV6.1.57-64
06:25 AM Bushman: 500 lines was not enought for me due to quite complex shapes i was making
06:25 AM PL7icnc: i did split them in beginning qith Qcad
06:26 AM Bushman: https://imgur.com/gallery/0iW4D
06:26 AM PL7icnc: so i got 2 otr more files
06:26 AM Bushman: things like this wouldn't even make half og the shapes
06:26 AM PL7icnc: i got more complex then y<ou
06:27 AM jthornton: Bushman: nice work!
06:27 AM Bushman: lol, it's not a contest!!! XD
06:27 AM Bushman: jthornton: thx man
06:27 AM PL7icnc: http://schwedenfeuer.de/feuersauelen.htm
06:27 AM PL7icnc: we make mostly firerpots for individual stuff
06:27 AM PL7icnc: logos
06:28 AM Bushman: nice!
06:29 AM Bushman: i wish i had access to manual plasma torch...
06:29 AM PL7icnc: Bushman, with qcad you can reduce the line count to a minimum
06:29 AM Bushman: i would so fu**ing CNC that shit :D
06:29 AM PL7icnc: so complex cuts getting faster and smoother
06:30 AM PL7icnc: Bushman, in 2012 thishas been the case
06:30 AM PL7icnc: and now we are 25 employs
06:30 AM Bushman: i see
06:30 AM PL7icnc: gardendoors
06:30 AM Bushman: anyway... back to solving issues with CNC
06:30 AM PL7icnc: lamings
06:30 AM PL7icnc: all kiund of housing shields
06:31 AM PL7icnc: ok probe
06:31 AM PL7icnc: Sir do you realy need the screen
06:31 AM PL7icnc: woudent it be 3 buttons
06:31 AM PL7icnc: as you only do a Z a XY and a hole
06:32 AM PL7icnc: thats all i got on the mashines around me
06:32 AM PL7icnc: for the rest needed below 1Percent of the work i got G38 in mdi
06:33 AM PL7icnc: gmoccapy got also extra button panels
06:33 AM PL7icnc: as pyvcp in axis
06:34 AM PL7icnc: SORRY rest time is over need to go working
06:34 AM PL7icnc: BYE
06:34 AM Bushman: bye
06:34 AM * Bushman 's hobby: answering to people who already left
06:34 AM jthornton: lol
06:34 AM jthornton: what gui are you using?
06:34 AM Bushman: in general?
06:34 AM Bushman: AXIS
06:35 AM Bushman: never touched anything else so yea...
06:35 AM jthornton: you can either use the probe routines as is with ngcgui or you can have some pyvcp buttons and call them as a subroutine
06:36 AM Bushman: i was hoping to be able to fix the probe screen
06:36 AM jthornton: got a link to it?
06:36 AM Bushman: as it is quite nice and has all the buttons
06:36 AM Bushman: yea, sure... 1 sec
06:36 AM jthornton: your selling it again lol
06:36 AM Bushman: https://github.com/verser-git/probe_screen_v2
06:37 AM Bushman: heh, lol
06:37 AM Bushman: well, i'm trying to sell it to myself...
06:37 AM Bushman: but i won't buy anything if it's not working :F
06:37 AM Bushman: 8:D
06:37 AM * Bushman has fat fingers and can't even type a ":D"
06:38 AM Bushman: there's another issue with this code where it says some variable sin't defined...
06:38 AM jthornton: wow that is a busy screen
06:38 AM Bushman: i've manually defined it from MDI
06:38 AM jthornton: it won
06:39 AM jthornton: 't lie to you...
06:39 AM Loetmichel: hmm, i posted this a few hours ago, got no answer, maybe now someone has one? -> I think coworker wasnt impressed with the fact that i could re-edge the bit... but that i did it on my desk freehand with a leatherman wave of all tools possible ;) ... preferably with shipping to germany?
06:39 AM Loetmichel: ups
06:39 AM Loetmichel: again:
06:40 AM Loetmichel: hmm, i posted this a few hours ago, got no answer, maybe now someone has one? -> hmm... anyone has a recommodation for the cheapest working wire feed (MIG) welder that would do 3mm sheet aluminium on ebay? ... preferably with shipping to germany?
06:40 AM jthornton: is there an echo in here
06:41 AM Bushman: echo in here
06:41 AM Bushman: in here
06:41 AM Bushman: here
06:41 AM Bushman: eer
06:41 AM Loetmichel: here here here
06:42 AM Bushman: -- a highlander came out of his house in the morning, looked at the valley, stretched, and yelled "Ahhh! What a nice weather we have today"
06:43 AM jthornton: I would suggest to start with a simple probe routine and work your way up to a complicated one like versers
06:43 AM Bushman: but the echo out of habit replied "...ly shit! ...ly shit! ...ly shit!"
06:44 AM Bushman: jthornton: but it has both! :D
06:45 AM Bushman: if i'll figure out why axis is spitting out errors, i won't have to create screens myself with ngcgui or what not :P
06:45 AM jthornton: post the exact error
06:46 AM Bushman: 2:45:30 Error: EOF in file:/usr/share/axis/images/axis.ngc seeking o-word: o<xplus> from line: 0
06:46 AM Bushman: please note that axis.ngc is a splash screen
06:46 AM jthornton: axis.ngc should not give that error...
06:46 AM Bushman: and the sub is invoked by some python code via a button
06:47 AM Bushman: the code snippets are in a subfolder macros
06:47 AM Bushman: where the author said to place them
06:47 AM jthornton: hmmm
06:48 AM Bushman: hmmm indid
06:48 AM Bushman: and google search led me to a bug in axis
06:50 AM Bushman: https://github.com/LinuxCNC/linuxcnc/issues/559
06:51 AM jthornton: that doesn't seem to be your issue as you stated the files are not using %
06:52 AM Bushman: exactly
06:52 AM jthornton: are the subroutines executable?
06:53 AM Bushman: hmm...
06:53 AM Bushman: actually nothing is
06:53 AM Bushman: not even the py files
06:53 AM jthornton: that only seems to be a requirement for M100 files
06:53 AM jthornton: so nevermind
06:55 AM Loetmichel: Bushman: sure that was a highlander and not someone from Wuppertal in germany?
06:55 AM Loetmichel: (never seen so much rain days over a year than when i grew up there)
06:55 AM Bushman: it's a polish joke i know translated on the fly
06:56 AM Bushman: also yes, i'm sure it was a highlander lol
06:56 AM Bushman: :D
06:58 AM jthornton: https://www.youtube.com/watch?v=zTXBCbFdMTY
06:58 AM XXCoder: cool
07:00 AM jthornton: https://qtpyvcp.kcjengr.com/showcase/mill_vcps.html
07:01 AM Bushman: no speakers in this machine
07:01 AM Bushman: any vital info in sound?
07:02 AM jthornton: dunno my speakers are usually off
07:02 AM XXCoder: my speakers is usually nonexistant
07:03 AM lanclanterns: What is wrong when only 2 ports work on a mesa 7i74? 7i74 is connected to a 7i92.
07:03 AM jthornton: didn't you ask that on the forum?
07:07 AM jthornton: https://mesaus.com/ do you guys get a 406 from there?
07:09 AM Bushman: no
07:10 AM beachbumpete1: Not acceptable an appropriate representation of the requested source/cound not be found on this server
07:10 AM jthornton: yea that's what I get
07:10 AM jthornton: morning pete
07:10 AM jthornton: no fear Deepashree is helping me
07:12 AM jthornton: hmm refresh the browser fixed it
07:16 AM beachbumpete1: morning
07:17 AM Bushman: moin
07:17 AM Bushman: hmm.. a different issue...
07:17 AM Bushman: anyone good with python?
07:17 AM Bushman: i have some libs missing i think.
07:17 AM Bushman: i get this as an error:
07:18 AM Bushman: Traceback (most recent call last):
07:18 AM Bushman: File "dxf2gcode.py", line 1150, in <module>
07:18 AM Bushman: from dxf2gcode_ui5 import Ui_MainWindow
07:18 AM Bushman: ImportError: No module named dxf2gcode_ui5
07:18 AM beachbumpete1: They're large dangeros snakes ;)
07:18 AM Bushman: i have pyqt5 installed
07:18 AM Loetmichel: beachbumpete1: considering that they are not poisonus: not THAT dangerous
07:19 AM beachbumpete1: yeah but I hear they can squeeze da life out of ya :)
07:19 AM jthornton: it's saying it can't find the module Ui_MainWindow
07:19 AM Loetmichel: beachbumpete1: they can
07:20 AM Loetmichel: but usually even the big ones are to timid to do that unless seriously provoked
07:20 AM Loetmichel: Friend of mine had a big phyton and a boa as pets in an appartment
07:20 AM Bushman: jthornton: yes, but why?
07:20 AM Loetmichel: i once didnt see the snake and tripped over it when walking in the hallway
07:20 AM beachbumpete1: and he was never heard from or seen again
07:21 AM Bushman: it works out of the box on my laptop with linux mint
07:21 AM Loetmichel: snake stopped, reversed a bit, looked at me condescending and moved on
07:21 AM Loetmichel: beachbumpete1: SHE
07:21 AM beachbumpete1: poor girl
07:24 AM jthornton: is the file there?
07:28 AM jthornton: Bushman: looks like Andy has replied to your topic on the forum
07:30 AM jthornton: lanclanterns: did you flash the 7i92 for the 7i74?
07:49 AM Bushman: jthornton: yes, some time ago... i've already repied
07:50 AM Bushman: 30 is bitwhise compatible with 12 (16, 8, 4 and 2 vs. 8 and 4)
07:52 AM lanclanterns: jthornton: yes, I flashed the 7i92 with the 7i92_7i77_7i74D bit file
07:53 AM lanclanterns: jthornton: it works nicely but with only two ports working on the 7i74
07:55 AM lanclanterns: jthornton: I checked by plugging a working 7i70 into each port on the 7i74
07:55 AM jthornton: may be a defective card, wait a bit for Peter to reply to your post
08:01 AM lanclanterns: jthornton: I thought so too, and got a replacement card, which does precisely the same thing
08:02 AM lanclanterns: jthornton: so I figured it has got to be either a firmware issue or config problem on my part
08:07 AM lanclanterns: jthornton: IIRC the original 7i92_7i77_7i74D bitfile was miscompiled so Peter slapped a fix together quick
08:08 AM JT-Shop: ok that makes sense
08:08 AM JT-Shop: I need to update mine
08:10 AM JT-Shop: does it work now?
08:22 AM lanclanterns: JT-Shop: Yes, I'm using the firmware that Peter recompiled. That's the one that has two of the 7i74 ports working
08:29 AM jthornton: ah then wait for Peter to fix that
08:34 AM Bushman: ok, turns out i'm blind idiot
08:34 AM Bushman: i had 2 sections with the same name
08:34 AM Bushman: after fixing it the probe screen started to operate
08:34 AM Bushman: but now for some reason the probe input is unresponsive
08:35 AM Bushman: electrically the probe and the input is working
08:35 AM Bushman: (checked with parport tester)
08:37 AM JT-Shop: open show hal configuration and put that pin in a watch window and check it
08:38 AM JT-Shop: dang the drive belt is $310!
08:39 AM Bushman: JT-Shop: but i said it works
08:40 AM Bushman: the pin is changing
08:40 AM Bushman: but anything related to it is not
08:40 AM Bushman: unless you mean to put the probe-in pin too?
08:40 AM * Bushman will actually try that too
08:42 AM Bushman: yup, probe-in is working too
08:42 AM JT-Shop: check that the pin is connected to a signal and that signal is connected to the probe screen
08:48 AM * Bushman sings: "98 tiny bugs in the code, ♪ 98 tiny bugs. ♫ you fix one up, compile it all, 99 tiny bugs in the code ♪♫"
08:49 AM Bushman: JT-Shop: any tips on how to do it? :P
08:50 AM Bushman: because i see the probe-in signal is working, don't really know what next :P
08:52 AM Bushman: it seems to be linked to "motion.probe-input" but when i navigate to parameters.motion there's no such signal
08:54 AM Bushman: pins.motion.probe-input works too
08:54 AM jthornton: in signals if you click on a signal it shows the links
08:54 AM Bushman: yes. i'm already on it
08:54 AM Bushman: it ends on pins.motion.probe-input
08:54 AM Bushman: it's not linked out
08:55 AM Bushman: only in
08:55 AM Bushman: ehh
08:55 AM Bushman: back to .hal file i guess
08:55 AM jthornton: is the parallel port pin linked to the signal?
08:55 AM Bushman: tes
08:55 AM Bushman: *yes
08:55 AM jthornton: hmm and what is not working?
08:56 AM Bushman: parport.0.pin-12-in-not ==> probe-in ==> to motion.probe-input
08:56 AM Bushman: parport.0.pin-12-in-not ==> probe-in ==> motion.probe-input
08:56 AM Bushman: and nothing else
08:57 AM jthornton: that looks correct for a normal probe input, but all bets are off with verse
09:00 AM Bushman: i tested with my basic config which i took a backup before installing anything extra
09:00 AM Bushman: and it works fine
09:00 AM jthornton: hi ho, hi ho it's off to work I go... gotta try and get an ancient hot plate welder to work again
09:00 AM Bushman: ♪♫♬
09:01 AM jthornton: yea so it must be something in that plasma thing
09:01 AM jthornton: better take my suitcase full of cables... no telling what kind of plc is in that old beast
09:02 AM Bushman: hehe
09:02 AM Bushman: s5
09:02 AM Bushman: XD
09:03 AM Bushman: or better yet, a hamster with a PhD flipping leavers :D
09:05 AM rmu: Bushman: you have versaprobe?
09:05 AM Bushman: umm... i don't think so. what is that?
09:06 AM rmu: nevermind
09:08 AM rmu: 13:32 < Bushman> https://github.com/verser-git/probe_screen_v2
09:08 AM JT-Shop: well I'm out of here for a while good luck sorting it out
09:08 AM perry_j1987: morning guys
09:08 AM rmu: Bushman: http://vers.by
09:09 AM rmu: Bushman: seems to be author of probe_screen_v2
09:09 AM Bushman: ah, yes...
09:09 AM Bushman: that's why it seemed to be familiar
09:10 AM Bushman: rmu: this is my probe v0.1a
09:10 AM Bushman: https://imgur.com/a/IUm710q
09:11 AM rmu: versaprobe looks pretty similar
09:11 AM Bushman: don't they all? :P
09:12 AM Bushman: ok, g2g, bbl
09:12 AM Bushman: bye
09:13 AM rmu: bye
09:28 AM Deejay: hi
09:36 AM perry_j1987: got this mitutoyo indicator all cleaned up
09:36 AM perry_j1987: whoever had it before loved red dykem
10:23 AM jym: Mornin folks
10:32 AM Deejay: hey there. morning was 12 hours ago ;)
10:33 AM jym: Deejay: OH, then it must be Beer O'clock then
12:24 PM perry_j1987: met a guy yesterday that said his great granddad invented the live center
12:29 PM sync: meh pingufan, you can't really use such an old machine anymore, try installing a modern chrome
12:58 PM Loetmichel: perry_j1987: did he have any proof?
12:59 PM perry_j1987: he said he has a framed letter from the president accommodating him for the invention. something about guys getting hurt with dead centers turning parts for the atomic bomb research back in the day
12:59 PM perry_j1987: i didnt see the letter
01:01 PM CaptHindsight: dead center is a place not a thing :)
01:02 PM perry_j1987: what do they call them in your state then :P
01:03 PM jym: in CaptHindsight's state they have a straight jacket embroidered with his name in it
01:16 PM CaptHindsight: perry_j1987: centers, same as in yours
01:19 PM perry_j1987: i always knew them as dead centers or live centers
01:19 PM CaptHindsight: jym thinks a thesaurus is an animal you find at the zoo
01:19 PM CaptHindsight: welcome to dumb joke hour
01:20 PM perry_j1987: heh
01:21 PM Rab: perry_j1987, I think this guy might have a framed letter for blowing smoke. Live center is an obvious and elementary idea, a trivial application of the same technology used to build the lathe...surely it would have been invented before 20th century?
01:22 PM CaptHindsight: Summerfest starts today up in dairy town
01:23 PM perry_j1987: no idea Rab
01:23 PM perry_j1987: wikipedia doesnt say anything on the subject haha
01:24 PM Rab: andypugh, congrats on making HaD yet again.
01:24 PM CaptHindsight: https://en.wikipedia.org/wiki/Talk%3ALathe_center
01:25 PM CaptHindsight: Piper tools has been manufacturing live centres since around 1937
01:25 PM CaptHindsight: so BS on the WWII claim
01:25 PM Rab: And that's in Australia.
01:26 PM perry_j1987: i'll prod the guy a bit more next time i talk to him see what more he says heh
01:26 PM CaptHindsight: pretty sure the Russians claimed to have invented it
01:27 PM CaptHindsight: http://www.pipertools.com.au/contact.htm
01:27 PM andypugh: Rab: I cheat, I know one of the writers.
01:28 PM andypugh: Over-complex drum-machine: https://www.youtube.com/watch?v=isosWOzmbe0
01:29 PM CaptHindsight: he first ‘turning machine with a metal frame’ was invented in 1751
01:30 PM andypugh: Maudslay?
01:30 PM FinboySlick: andypugh: Sheesh, it evolved a lot since I last saw it.
01:30 PM CaptHindsight: The first fully documented, all-metal slide rest lathe was invented by Jacques de Vaucanson around 1751. It was described in the Encyclopédie.
01:31 PM CaptHindsight: so it comes down to how you define a lathe
01:35 PM Jymmm: glorified drill press
01:39 PM Rab: https://upload.wikimedia.org/wikipedia/commons/f/f8/A_la_m%C3%A9moire_de_J.M._Jacquard.jpg
01:39 PM CaptHindsight: https://youtu.be/V7PeN9F4Dns?t=62 how does a build platform on a cantilever of this length keep steady?
01:39 PM CaptHindsight: it's around 2ft (.6m)
01:39 PM Rab: "The Most Famous Image in the Early History of Computing. This portrait of Jacquard was woven in silk on a Jacquard loom and required 24,000 punched cards to create (1839). It was only produced to order. One of these portraits in the possession of Charles Babbage inspired him in using perforated cards in his analytical engine."
01:39 PM Rab: First digital image, or at least pixel art?
01:39 PM Rab: Vaucanson's lathe: https://translate.google.com/translate?sl=fr&tl=en&u=https%3A%2F%2Fwww.arts-et-metiers.net%2Fmusee%2Ftour-charioter-de-vaucanson
01:41 PM Rab: Looks at least as legit as many DIY CNC builds today.
01:42 PM CaptHindsight: so you're saying that DIYers don't learn from history?
01:42 PM jym: CaptHindsight: That's bullshit...
01:42 PM Rab: No need to state the obvious.
01:42 PM jym: CaptHindsight: You find it at the pet store silly!!!
01:45 PM Rab: Hmm, the center is visible, and has some suspicious features...could it be live?!?
01:46 PM Rab: Time for a trip to le Musée des arts et métiers.
01:46 PM CaptHindsight: he have a specific purpose in mind for his lathe?
01:47 PM CaptHindsight: did
01:47 PM Rab: Yes, turning copper cylinders for texturing silk.
01:51 PM Rab: prismatic ways detected
01:51 PM CaptHindsight: http://www.theglobaleducationproject.org/egypt/articles/hrdfact3.php
01:53 PM CaptHindsight: https://youtu.be/Ti88ZgNSV7Y?t=229 ancient lathe?
01:55 PM Rab: wow
02:08 PM Rab: I think that guy's missing something. That design would have terrible rigidity for fixing a tool for linear facing. But it could be ideal for bowl turning, with the tool swinging on a round beam between the posts and the post height defining the degree of curvature.
02:10 PM Rab: Also the round thing on the ground seems to be a negative of the imprint on the slab. I think it's upside down, and was probably a turntable rotating on the slab (or possibly an unfinished workpiece, I guess).
02:11 PM CaptHindsight: work got interrupted by a war
02:13 PM CaptHindsight: yes, would be better for metrology than cutting
02:13 PM Rab: I think he's right that the slab was designed to go between the posts, but I wonder about its current position. Maybe they moved it so they could turn something on the OD, like a big parcheesi piece.
02:14 PM Rab: The "turntable" seems like it's in the right position to have been tipped over off the slab.
02:14 PM CaptHindsight: teenagers 300 years ago pranked the site
02:14 PM Rab: By invading hordes, say.
02:15 PM jym: The distance of the slab to the posts, could have been by adding weights, but not sure how the disc would have been turned
02:16 PM CaptHindsight: stone turntable on stone records
02:16 PM Rab: Same way they would turn a big stone disc now: lots of Indian dudes.
02:16 PM CaptHindsight: how many indian dudes does it take to change a lightbulb?
02:17 PM CaptHindsight: old invading hordes joke
02:19 PM Rab: As soon as it's fewer than chinese dudes, neoliberal capitalism is ready to pounce.
02:21 PM jym: That's a small square hole, too small for a turning shaft... maybe alignment purposes???
02:21 PM jym: driven shaft*
02:23 PM jym: If they built a lathe, I' sure then knew about bearings
02:23 PM jym: I'm*
02:26 PM Rab: What is a bearing, but a friendly log or rock covered in animal fat?
02:27 PM jym: that's what I'm talking about
02:27 PM Rab: Probably longer-lived than some of the stuff at Harbor Fright.
02:29 PM jym: I can't figure out the SQUARE hole though, unless they had iron back then
02:30 PM CaptHindsight: if the stylus has enough mass it would still drag on the rotating stone below and slowly cut grooves
02:31 PM jym: I'm thinking it was made to create wheels, not engrave. Those grooves are just a sacrafical board so to speak
02:32 PM CaptHindsight: the vertical hanging stylus would be pushed radially but the weight would resist..
02:32 PM CaptHindsight: yeah it's not fast but it worked
02:33 PM jym: I think the cutting was done on the rectangular slab, the posts are just a pivot point
02:33 PM Rab: jym, could be, and they had a lot of stone to cart around for the nearby well.
02:33 PM CaptHindsight: not bad for a bunch of heathens
02:34 PM jym: From the posts, the could "hang" a cutting tool, and use a long "20 foot?" pole with weights on the end to apply pressure
02:35 PM jym: or just gravity fed pressure
02:35 PM jym: maybe like how a victorlia needle sits on a record
02:36 PM Rab: Blah, Google Maps imagery of the Hampi site is terrible.
02:38 PM jym: has anyone hand shaped/cut granite tile?
02:38 PM Rab: https://karnatakatravel.blogspot.com/2018/05/stone-pillars-and-turned-discs-hampi.html
02:40 PM andypugh: CaptHindsight: I am pretty sure there is a replica of the Vaucanson (and the Maudslay) lathe in the Henry Ford Museum.
02:41 PM CaptHindsight: haven't been there since I was ~10
02:41 PM andypugh: How far is it?
02:42 PM Rab: Hmm, I guess that is a fixed center, unless something's not obvious: https://www.gracesguide.co.uk/images/f/ff/JD_2019_CNAM_Vaucanson01.jpg
02:42 PM jym: We used to move 700 lb safes using 1/4" steel rods
02:42 PM CaptHindsight: Detroit, 4 hr drive
02:42 PM andypugh: I was there a couple of years ago. It has some very cool stuff. Including my all-time favourite car.
02:43 PM jym: andypugh: did it have a Y-Flux capacitor?
02:44 PM andypugh: No. In fact it only has three wheels.
02:44 PM gregcnc: I didn't see the workshop when I went
02:46 PM andypugh: It’s a slighlty eccentric choice for “favourite car” https://www.thehenryford.org/collections-and-research/digital-collections/artifact/33657/#slide=gs-219621
02:47 PM andypugh: Hmm, the steering is identical to my Ner-a-Car
02:47 PM sync: neat
02:50 PM andypugh: Hmm, after a bit of a random walk. Quick quiz. (don’t look it up, that would be chearting) Who was the first to fly non-stop across the Atlantic ocean?
02:50 PM gregcnc: not Lindberg?
02:52 PM gregcnc: I was just reading a story about the Packard Diesel radial and the duration record it set.
02:53 PM gregcnc: https://www.airspacemag.com/history-of-flight/85-hours-in-1931-airplane-180968358/
02:54 PM roycroft: hi folks
02:54 PM roycroft: before i give up on this idea i'll ask once again, since there are some different people here now than before
02:54 PM roycroft: 1. is my 12x26 belt-driven lathe likely rigid enough for carbide insert tooling to make sense for me to use
02:54 PM roycroft: and if so,
02:54 PM gregcnc: sure
02:55 PM gregcnc: I saw your Q's yesterday
02:55 PM roycroft: 2. does anyone have a link to somewhere that would help me make sense of the different inserts available?
02:55 PM gregcnc: tons of options, tons to learn
02:55 PM roycroft: i find all sorts of sites that sell them
02:55 PM roycroft: but none that explain the differences
02:55 PM roycroft: i found one that showed the same type insert but with like 30 different chip breakers
02:56 PM roycroft: and did not say a word about which chip breaker geometry is good for which application
02:56 PM roycroft: i don't expect to buy some inserts and have everything work perfectly right away
02:56 PM roycroft: but i'd like to choose from, say, 3 types instead of 30
02:56 PM gregcnc: i wish I could say it was easy, but ti's not
02:56 PM roycroft: thanks for the confirmation that my lathe will likely work fine with them
02:56 PM roycroft: i thought so
02:56 PM roycroft: i don't expect it to be easy
02:57 PM roycroft: but i hope it's not extremely expensive and time-consuming and all but impossible
02:57 PM andypugh: roycroft: I suggest you should buy some inserts and expect everything to work fine straight away.
02:58 PM roycroft: i try not to be too terribly self-delusional
02:58 PM andypugh: I use whatever I can find cheap on eBay and for my use they all work fine.
02:58 PM roycroft: it helps me retain what i like to pass off as a semblence of sanity
02:58 PM gregcnc: expect to be operating below the recommended feed and speeds
02:58 PM gregcnc: this often means finishes are not what the tools are capable of
02:59 PM gregcnc: but you still get the life
02:59 PM andypugh: I have, eventually, bought some special small-radius tools for tiny work, and some high-rake tools for brass. But for aluminium, steel, stainless, cast iron and brass (when I can put up with the chips flying everywhere) I use whatever happens to already be in the holder.
03:00 PM gregcnc: that is an option
03:00 PM andypugh: No reason to limit the speed on your lathe.
03:01 PM roycroft: the carbide inserts like aggressive cuts, don't they?
03:01 PM andypugh: gregcnc: Interesting article, but it fails to mention the most interesting diesel Aero engine. Look up the Napier Nomad
03:01 PM gregcnc: if you can keep up
03:01 PM gregcnc: Yes, i know aero engines
03:02 PM andypugh: roycroft: To be honest I think that there is a lot of twaddle talked about inserts in home workshop machines.
03:02 PM roycroft: yes, andypugh, i know that well
03:02 PM roycroft: which is why i'm asking here
03:02 PM andypugh: gregcnc: You have to love a diesel engine with an afterburner :-)
03:02 PM gregcnc: psotive geometry will ceratinly be helpful for light machines
03:02 PM roycroft: i have, i think, a fairly good sense of the level of experience of folks here, and what kinds of machines they operate
03:02 PM roycroft: while irc is part of the internet, this channel is a very very small subset of the internet
03:03 PM roycroft: and i feel i can trust advice given here more than that which i find on the internet at large
03:03 PM roycroft: so i read and study, and then get my sanity checks here
03:03 PM roycroft: if i'm honest, i don't even know how hard i can push my current lathe
03:04 PM roycroft: i worked with one of those little harbor freight 7x10 machines for so long i got used to taking really light cuts and going really slowly on everything i do
03:05 PM SpeedEvil: Till the bed snaps in half, then back off a thou.
03:05 PM roycroft: taking a 0.050" pass on mild steel seems like a really big cut for me, and i know that my lathe doesn't even feel it
03:05 PM roycroft: i should probably push it harder until it starts pushing back, then i'll know
03:07 PM andypugh: This is my old 8x20 Indian clone of a cheap Chinese lathe, with carbide tooling and working on moderately tough sprocket material.
03:07 PM andypugh: https://www.youtube.com/watch?v=nIYMfyf4jDI
03:08 PM roycroft: you know, abom uses his victor lathe a lot
03:08 PM roycroft: and that's not too much bigger than mine
03:08 PM roycroft: he uses carbide insert tooling on it almost exclusively
03:08 PM andypugh: Though based on the apparent CSS this was after I had replaced the tiny little 1/4” V belt with 2x A section.
03:08 PM gregcnc: size of lathe has nothign to do with this
03:08 PM roycroft: i thought it did, indirectly
03:09 PM gregcnc: why
03:09 PM andypugh: I use carbide because: a) I can afford it and b) I can’t be bothered to grind HSS.
03:09 PM roycroft: in that the lathe has to be fairly rigid to cut really aggresively
03:09 PM roycroft: and mass = rigidity
03:09 PM gregcnc: why cut aggressively?
03:09 PM roycroft: but this is assuming that all the folks the say carbide insert tooling needs to cut aggressively are correct
03:09 PM roycroft: and i don't know that to be a fact
03:10 PM roycroft: i just know that it's an internet urban legend
03:10 PM gregcnc: if you look in a catalog you'll see roughing to super finishing insert grades
03:10 PM roycroft: if you say otherwise i definitely question The Internet(tm)'s wisdom
03:10 PM andypugh: It works best and gives a better finish if the cut depth is a large fraction of the nose radius. But that’s true of HSS too.
03:11 PM gregcnc: and that's the thing, you have to understand cutter geometry
03:11 PM andypugh: So for a weak spindle you _might_ want to be using smaller nose radii.
03:11 PM roycroft: yes, i've found that to be the case with my hss tooling
03:11 PM roycroft: if i grind the nose radius too big i have to take a big cut to get a decent finish
03:11 PM SpeedEvil: roycroft: The internets wisdom can suck badly.
03:12 PM andypugh: i bemoan the fact that inserts are hard to search eBay for.
03:12 PM roycroft: i'm still not experience enough to know how to get the best finish
03:12 PM gregcnc: tool pressure, radius, feed rate all interact
03:12 PM roycroft: speedevil: this is why i don't trust it, and ask questions of people who know what they're doing
03:12 PM SpeedEvil: andypugh: 'You have no need for wildcard searches, so we removed them'
03:12 PM roycroft: as opposed to people who know what they think they're doing :)
03:12 PM andypugh: I care bout shape and whether it will clamp to my holders, so it’s C (don’t care) (don’t care) T that I need.
03:12 PM roycroft: well i might just pick up a shars insert holder and a couple of their recommended inserts
03:13 PM gregcnc: everyone thinks they know what they are doing, only some are actually correct
03:13 PM roycroft: since they're fairly inexpensive and commonly used
03:13 PM SpeedEvil: Also, people who know what they are doing don't always know what they aren't doing even if it would be better.
03:13 PM roycroft: yes, gregcnc
03:13 PM roycroft: and what i'm saying is that i believe there's a greater concentration of them that actually do know what they're doing here on this channel than on the internet at large
03:14 PM roycroft: anyway, it's time for me to go home
03:14 PM SpeedEvil: :wave
03:14 PM roycroft: it sounds like there's not going to be any magic document that will guide me safely and quickly through the insert forest
03:14 PM roycroft: i'll have to make my own path
03:15 PM jym: one bloody step at a time ;)
03:15 PM roycroft: and make a few wrong turns along the way
03:15 PM SpeedEvil: Search aliexpress by price - what can go wrong.
03:15 PM andypugh: I can’t remember what ToT says: https://www.youtube.com/watch?v=rsFFWYo8ugw&t=361s
03:15 PM gregcnc: most brands have grades that will handle a wide range, plus the specialty grades
03:15 PM andypugh: I will watch it and see if I agree :-)
03:16 PM andypugh: It comes down to a suitable tool making 10,000 parts and an unsuitable one making 1000. I only ever make 1 dozen at most.
03:16 PM gregcnc: that too
03:17 PM gregcnc: I only seem to chip inserts doing dumb things
03:17 PM andypugh: (And for long production you would want chip breaking. One obvuous thing in my earlier video of my lathe is that the swarf would have been death to a chip conveyor)
03:18 PM SpeedEvil: Chip winders would be kinda neat.
03:18 PM SpeedEvil: Shame it's impractical.
03:30 PM andypugh: I think I have heard of powered chip cutters.

03:40 PM Deejay: :)
03:41 PM jym: Tom_L: it's 2100 for him and he needs his beauty rest
03:41 PM Tom_L: i'll vouch for that
03:41 PM Deejay: 2236!!!
03:41 PM Deejay: yes, i need a lot of beauty rest ;)
03:41 PM Tom_L: whoz really keepin track?
03:41 PM jym: Deejay: Jsut goto bed
03:42 PM Tom_L: and here i was bettin we could keep him up another 30 min
03:48 PM jym: 30,000 grit stone?! YEOW
03:56 PM gregcnc: ~0.5 micron particle size
04:12 PM net|: https://300mpg.org/2019/04/25/briggs-stratton-6-wheel-hybrid/
04:15 PM jym: gregcnc: Heh, I read that at first as NEGATIVE 0.5 um =)
04:19 PM andypugh: Antimatter grinding stones would be quite fast, but might affect the heat-rtreatment.
04:22 PM jym: andypugh: and the space-time continuum
04:24 PM andypugh: Antimatter is perfectly normal and understood stuff.
04:24 PM jym: till soemone tosses in some matter with it
04:24 PM andypugh: It’s uncommon, but a conventional part of physics.
04:25 PM jym: has anyone milled granite??
04:26 PM jym: or engraved granite? What kind of tooling ?
04:28 PM Tom_L: diamond
04:30 PM jym: Tom_L: anything else?
04:30 PM Tom_L: something harder than granite
04:32 PM andypugh: I think you can cut cranite with carbide.
04:35 PM sync: diamond is probably the best
04:36 PM roycroft: cranite being the rocks that fill up some people's heads?
04:36 PM jym: Hmmm, think I'll just stick with the laser then
04:37 PM Tom_L: the cutters are more abrasive looking than 'toothed'
04:37 PM Tom_L: jym how thick?
04:37 PM Tom_L: get a cheap tile saw
04:39 PM jym: Tom_L: maybe 1/8" engraving, but the laser will do... https://i.imgur.com/qm1Kf8t.jpg
04:41 PM andypugh: That’s a funny-looking seal
04:42 PM jym: andypugh: Of course it is silly.. it's a penguin
04:42 PM andypugh: Doh! I feel so stupid now
04:44 PM jym: WTH... I have 2000 grit, but no 100 grit ARGH, murphy is a dead man when I catch him!
04:51 PM roycroft: isn't 2000 grit 20 times better than 100 grit?
04:52 PM tiwake: roycroft: its a logarithmic scale
04:52 PM tiwake: oh
04:53 PM tiwake: (thought you were legit talking about sandpaper grit particle size)
04:53 PM jym: tiwake: *I* am
04:53 PM andypugh: 2,000,000 grit is homeopathic grit where the grains are smaller than atoms, and that’s the best of all.
04:53 PM roycroft: but is it iso 2000 (P2000) or cami 2000?
04:54 PM roycroft: or that japanese grit stuff?
04:54 PM roycroft: american grit is true grit, isn't it?
04:54 PM jym: just good old fashion wet/dry stuff
04:54 PM roycroft: it takes 2000 european grits to make 1000 american grits
04:55 PM roycroft: so we can conclude that europeans have tiny grits
04:58 PM jym: I'm just going thru sandpaper way too fast, barely getting the toolmarks out on one edge
04:59 PM roycroft: i can say, a year and a half after i started buying festool sanders, that their abrasives are extremely good
04:59 PM roycroft: they cost about 1.5x as much as other decent quality abrasives, but they last 2-5x longer
04:59 PM roycroft: in part because of the quality of the abrasive itself
05:00 PM roycroft: but in large part because of festool's superior extraction
05:00 PM jym: This is just a one off. Was asked to make a memorial (of sorts) and hand polishing the edges of the granite.
05:00 PM roycroft: i just got some ceramic sanding belts for my belt grinder
05:00 PM roycroft: as in the arrived today
05:01 PM roycroft: it will be interesting to see how well they hold up
05:01 PM jym: ceramic? grit?
05:02 PM roycroft: https://www.ebay.com/itm/202034956873
05:02 PM roycroft: 36 grit
05:03 PM roycroft: i started out with an assortment of aluminium zirconia belts
05:03 PM roycroft: the 36 is pretty much shot after considerable use
05:03 PM roycroft: so i thought i'd try some ceramic belts to see if they last even longer
05:03 PM sync: I really like VSM abrasives
05:04 PM roycroft: i'm thinking that carbide insert tooling is going to be kind of like grinding belts
05:04 PM roycroft: heaps of options, and a lot of time spent experimenting until i find what i like that works well for me
05:05 PM roycroft: and actually, similar pricing
05:05 PM roycroft: good quality grinding belts are rough $10 each, as are good quality carbide inserts
05:05 PM roycroft: roughly
05:06 PM roycroft: i should probably try some 24 grit belts too
05:06 PM roycroft: i got some 24 grit flap sanding discs a while back for grinding weld beads, and they are amazing
05:30 PM jthornton: I think the coarse flap wheels I have are 40 grit...
05:32 PM roycroft: i used to use some 36 grit that i would get at hf
05:33 PM roycroft: they worked decently but wore out after only a couple minutes
05:33 PM roycroft: these 26 grit ones i got at my local steel supplier
05:33 PM roycroft: they're made in germany
05:33 PM roycroft: and they lst a long, long time
05:33 PM roycroft: ~45 minutes of solid grinding before one is too worn to cut fast
05:34 PM roycroft: but it can still be used for polishing after that
06:19 PM jthornton: I need to find some, I usually get mine from mcmaster
06:20 PM jthornton: hmm they only have 36 grit
06:21 PM jthornton: https://www.mcmaster.com/4867a11 I need to get some of those
06:26 PM roycroft: i use 24 grit and 120 grit
06:26 PM Tom_L: 36?
06:27 PM Tom_L: i've got boxes of round pads i got from my bud that made the cutting press for 3M. they gave him all sorts of material to test with
06:27 PM Tom_L: fine to 36 grit
06:28 PM roycroft: i've been meaning to try the norton blaze discs for paint removal, cleaning up where i don't want to do a lot of grinding
06:28 PM roycroft: they're expensive but they supposed last a really long time
06:30 PM jthornton: that disk is for right angle weld cleanup and I do a lot of that
06:30 PM roycroft: https://www.amazon.com/dp/B00939MUAM
06:30 PM roycroft: yeah, i saw that, jthornton
06:30 PM Tom_L: he made all sorts of presses including the one that stamped the big firebird on the hood of the old ponitac car
06:30 PM roycroft: the flaps wrap around the sides of the discs
06:31 PM roycroft: i might have to try some of those
06:31 PM jthornton: I have some work on the bench that need them now lol
06:31 PM roycroft: of course, i just bought 40 of the 24 grit german flap discs
06:31 PM roycroft: they were selling them really cheap in bulk - $25 for a box of 10
06:31 PM jthornton: been putting it off because of the difficultly in cleaning the welds
06:32 PM jthornton: that's cheap
06:32 PM roycroft: yes
06:32 PM roycroft: i bought one box because i was dubious
06:32 PM roycroft: but the first one worked so well i went right back and bought 3 more boxes
06:32 PM roycroft: 40 of those discs will last me a really long time
06:33 PM roycroft: if you're interested i can see if they have any more
06:33 PM jthornton: yea if you have tried them I'd be interested in getting a box
06:33 PM roycroft: even with shipping they would be really cheap
06:34 PM roycroft: ok, i'll check with them next time i'm over there and i'll pick up a box for you if they still have them
06:34 PM jthornton: I can email a shipping label
06:34 PM roycroft: great
06:34 PM jthornton: just need to know the weight
06:34 PM roycroft: yeah, i could let you know that ahead of time
06:34 PM jthornton: ok, cool
06:34 PM roycroft: it might be 2-3 weeks before i'm over there again though
06:34 PM roycroft: or maybe tomorrow
06:35 PM roycroft: if it's not really soon i'll check with you again before i get them
06:35 PM roycroft: worst case, of course, is you'll change your mind and i'll have an extra box
06:35 PM roycroft: and that would not be horrible
06:35 PM jthornton: no problem fortunately time is not pressing on me any more lol
06:35 PM roycroft: the country fair is coming up in early july
06:35 PM roycroft: and our booth got pretty demolished over the winter due to a really bad snowstorm
06:35 PM roycroft: so i'm scrambling to get it rebuilt in time for the fair
06:35 PM jthornton: we have a fall festival in October down in Corning Ark.
06:36 PM roycroft: once the fair is over i'll be able to chill a bit
06:36 PM jthornton: what is the fair about?
06:36 PM roycroft: it's about escaping the fake news world and spending a few days in the real world where people actually like each other :)
06:36 PM roycroft: it's a hippie fair
06:37 PM jthornton: cool, I don't watch the news or wear a watch...
06:37 PM roycroft: actually a pretty incredible event
06:37 PM roycroft: there are over 300 booths
06:37 PM roycroft: everything sold there must be hand made
06:37 PM jthornton: wow that is big for a hippie fair
06:37 PM roycroft: there are a couple hundred food vendors as well
06:37 PM roycroft: a dozen stages
06:37 PM roycroft: lots of music, vaudeville acts, spoken word
06:37 PM jthornton: how long does it last?
06:37 PM roycroft: 3 days
06:37 PM jthornton: nice
06:38 PM roycroft: and this year is the 50th anniversary
06:38 PM roycroft: so it's going to be on hell of a party
06:38 PM roycroft: phil lesh will be playing
06:38 PM roycroft: nobody from the grateful dead has played there in about 25 years
06:38 PM roycroft: the dead were closely associated with the fair in the early days
06:38 PM jthornton: one day I'd like to go to the Wisconsin state fair
06:38 PM jthornton: that's pretty cool
06:38 PM roycroft: i work at an herbal products booth
06:39 PM roycroft: the original booth owner was a midwife/herbalist
06:39 PM jthornton: are the dead still living?
06:39 PM roycroft: all but jerry and pigpen
06:39 PM roycroft: she's retired now, and her daughter has taken over the booth
06:39 PM jthornton: I like their music
06:39 PM roycroft: they were tight with the marry pranksters
06:39 PM roycroft: and ken kesey was a member of that lot
06:40 PM roycroft: ken was a local, and his family founded the springfield creamery in the early '60s
06:40 PM roycroft: they make nancy's yogurt, which is sold nationwide
06:40 PM jthornton: I've not seen that
06:40 PM roycroft: they were in financial trouble in the early '70s, and the dead came up and did a benefit concert for the creamery in 1974 at the country fair site
06:40 PM roycroft: there's a film of that concert that just came out a couple years ago
06:41 PM roycroft: it's called "sunshine daydream"
06:41 PM roycroft: i've had a bootleg of that show for decades
06:41 PM jthornton: I'll have to look for that
06:41 PM roycroft: but the official film was tied up with legal problems until just a couple years ago
06:41 PM roycroft: finally it's out
06:44 PM roycroft: new riders of the purple sage released a live album of their set at that benefit concert
06:44 PM roycroft: and it was 1972, not 1974
06:45 PM roycroft: jerry garcia, phil lesh, and mickey hart were founding members of nrps
06:45 PM roycroft: although none of them were in that band when they did the springfield creamery benefit
06:46 PM roycroft: the fair is a non-profit, and it uses the revenue to buy more land for the fair site
06:46 PM jthornton: cool
06:46 PM roycroft: the fair site is along the long tom river, which is a rich archeological site
06:46 PM roycroft: they're dedicated to preserving the artifacts and keeping te site as close to nature as possible
06:47 PM roycroft: we have to take the decking off our booth right after the fair, for example, so that sunlight and rain can get in
06:47 PM roycroft: it gets totally returned to nature after the fair until about six weeks before the next one
06:47 PM roycroft: and they also take profits and distribute them in local communities
06:47 PM roycroft: to help the schools, parks, etc.
06:47 PM roycroft: so it's a pretty cool thing
06:47 PM jthornton: cool
06:48 PM roycroft: we get to party like crazy
06:48 PM roycroft: and help people
06:48 PM roycroft: what could be better? :)
06:48 PM pcw_mesa: Well rats, that motor I got with the BISS interface encoder has a brake, wonder if it can be disabled without having to supply 24V or complete disassembly
06:48 PM jthornton: yea pretty cool to give back to nature and help people at the same time
06:48 PM * jthornton hands pcw_mesa a .44 magnum to remove the brake
06:49 PM roycroft: https://www.amazon.com/dp/B01B8GQ0BW
06:49 PM roycroft: i keep looking at those
06:49 PM roycroft: they're a lot cheaper than the norton ones
06:49 PM pcw_mesa: well yes but that might be a bit detrimental to the encpder
06:49 PM jthornton: well crap I've scraped the scab off and now I'm bleeding and it won't stop so off to patch me up
06:50 PM roycroft: but people rave about the nortons
06:50 PM roycroft: use duct tape
06:50 PM roycroft: that will stop the bleeding
06:50 PM roycroft: and it will wake you up when you remove it
06:50 PM jthornton: lol
06:51 PM roycroft: i think i'll check with a local welding shop on those abrasive discs to see if they have any
06:51 PM roycroft: the top of the stand i built for my belt grinder is 1/4" steel, and it has a lot of overspray on it
06:52 PM roycroft: i want to keep it bare metal
06:52 PM roycroft: so a paint removal disc would be nice
06:52 PM roycroft: those flap sander discs are too agressive for that - i want to just remove the paint
06:53 PM * jthornton hates being on blood thinners one tiny scratch and it's the Julia Childs scene at SNL
06:53 PM * roycroft hands jthornton a bottle of red wine to go with his scab repair procedure
06:56 PM * jthornton is sipping on some Cabernet Sauvignon
06:56 PM jthornton: I think it stopped...
06:57 PM jthornton: chow time here
06:57 PM jthornton: pcw_mesa: gotta aim careful...
08:02 PM _unreal_: there letting my mill level one section of its bed
08:02 PM _unreal_: just finished hand writing the code. saddly I'm running on turbocnc right now because my motion control board got fried. and I'm waiting for the replacement to come in

10:14 PM jym: Never seen two tools used at once before... https://youtu.be/J7_0kKwpjw8?t=878
10:38 PM roycroft: is it really more economical to machine a crankshaft from a piece of rod now than to cast then finish machine it?
10:38 PM roycroft: or would that video be of a prototype?
10:45 PM Tom_L: that's either a custom crank or prototype
10:45 PM Tom_L: forgings on mass production are still cheaper
10:47 PM roycroft: ok, that seemed like a big waste of time and material to me
10:47 PM roycroft: if it were a production process
10:47 PM roycroft: i mean, it was fun to watch
10:48 PM roycroft: but i sat there and said to myself "that machine is cutting 80% of the metal away - there's too much metal there to begin with"
10:54 PM jym: roycroft: you never seen the cnc porn?
10:58 PM roycroft: i've seen enough of it
