01:30 AM Loetmichel: *ahhh* Who damaged the weather? Had t scrape ice off the windsiheld... in mid april in central germany? *brrr* *shiver*
01:37 AM Deejay: moin
01:38 AM sensille: the problem with anecdotal evidence
01:39 AM CaptHindsight: April is a crapshoot here as well, can be 30C+ can be -10C and snow
01:39 AM XXCoder: sens yep
01:43 AM Loetmichel: yeah, april is known to be a moody mistresss in germany, too.
01:43 AM Loetmichel: but that was a bit "unexpected", especially because it was warm yesterday when going to sleep
01:45 AM CaptHindsight: we were 27C last week for a few days, then back down to 1C at night and 12C days
01:46 AM CaptHindsight: I'm just glad that all the snow melted
01:46 AM CaptHindsight: and the trees are just getting their new leaves
01:49 AM CaptHindsight: Brand: HeeChoo https://www.amazon.com/Linear-Actuator-BallScrew-Manual-Controller/dp/B086RKD7PW
01:53 AM CaptHindsight: chinese linear ballscrew stages for 1/5 the price of good ones
01:54 AM CaptHindsight: how long will they last if you clean and relube them before use?
03:09 AM CaptHindsight: "The warranty period is either one year or the product runs up to 8,000 hours.
03:09 AM CaptHindsight: "
04:16 AM Tom_L: morning
05:26 AM JT-Cave: morning
05:31 AM veegee: Ok so now I know what burnt hair smells like
05:31 AM veegee: I lit my propane burner a second too late with the propane flow a tad bit too high
05:31 AM veegee: And you can guess what happened
05:32 AM veegee: Flash fireball explosion of propane up to my elbow
05:32 AM veegee: It was instantaneous. So just high temperature but not long enough to actually burn skin
05:33 AM veegee: All the hair on my arm is now only 1mm long though
05:34 AM veegee: The tips of each strand of hair completely burned off but that's the worst of it. Scary more than anything
05:35 AM veegee: I need to put in one of those continuous spark ignition thing that creates an arc continuously or multiple times per second until the flame is lit
05:35 AM veegee: Now my whole arm smells like burnt hair and I haven't installed a shower in the workshop yet :(
05:35 AM veegee: That's the one thing this place is missing
05:36 AM veegee: This is the burner: https://www.amazon.ca/Outdoor-Propane-Adjustable-0-20PSI-Regulator/dp/B06XTGCQ7P
05:37 AM veegee: Overkill for just boiling a kettle of water but it does it faster than anything else I've ever tried.
05:38 AM veegee: Haven't tried oxy acetylene though. I suspect that'll just melt a hole in the kettle. Probably needs to be a nice thick pure copper kettle with heat spreader fins to take advantage of that
05:59 AM _methods: if you could master the fireball for hair removal you could be a millionaire
06:18 AM rs[m]: why not dump 100g or so Po210 into the kettle, that will heat it very quickly.
08:34 AM miss0r: JT, The first filterconsole is ready to be shipped now: https://imgur.com/a/lANxA5O
08:47 AM JT-Shop: looks real nice except for the extra teflon tape hanging out lol
08:51 AM miss0r: Yeah I know. Its a thorn in my eye too :)
08:51 AM miss0r: but it couldn't be helped
10:10 AM gregcnc: liquid or paste compound
10:57 AM R2E4: anyone installed latest QTplasmaC?
11:26 AM JT-Shop: I try and avoid plasmac
11:54 AM miss0r: gregcnc: tape
03:09 PM JT-Shop: I was about to use a fitting that had been used on the Sponge Bob machine we made so changed my mind it might still have filter oil in it
03:10 PM W1N9Zr0: what's a Sponge Bob machine?
03:14 PM JT-Shop: it oiled the yellow air filter for a B&S engine
03:14 PM JT-Shop: the filter reminded me of Sponge Bob so the machine was named that
04:06 PM CaptHindsight: you know that you have purchased a quality linear positioner when you have to reassemble it right out of the box so that the stage doesn't bind
04:12 PM SpeedEvil is now known as Guest31881
04:24 PM JT-Shop: some guy from Laredo wants to buy 3 7i77 png kits and wants my bank information so he can transfer the money LOL
04:39 PM rs[m]: CaptHindsight: https://github.com/scottalford75/Remora
04:39 PM Connor: Stupid question. I followed some instructions a few days ago on a few install to make the machine auto-login.. and it would even do it if you logged out. I had to reload for reasons. I thought I followed the same steps to get it to auto login. and it does. but, not when you logout. The first install DID. I'm not sure what would have changed.. any one seen this?
04:39 PM rs[m]: CaptHindsight: source looks legit, seems to be mbed application
04:40 PM JT-Shop: on debian based systems you have to edit /etc/lighdm/lighdm.conf to enable auto log in
04:41 PM JT-Shop: in the [Seat:*] section autologin-user=john
04:41 PM JT-Shop: autologin-user-timeout=0
04:41 PM Connor: Yup. That's what I did...
04:41 PM Connor: https://unix.stackexchange.com/questions/302400/auto-login-on-xfce-in-jessie
04:42 PM Connor: followed the instructions with 19 Ups
04:42 PM JT-Shop: did you edit it in the seat or the section above that which is comments?
04:42 PM Connor: No, the seat. Like I said, it works if I reboot..
04:42 PM Connor: just not if I logout.
04:42 PM Connor: I could have sworn, if I logout, it would immediately log back in.
04:42 PM JT-Shop: ah yeah logout is another story
04:43 PM JT-Shop: nope
04:43 PM Tom_L: just don't log out :)
04:43 PM JT-Shop: lol
04:43 PM Tom_L: jeese
04:43 PM Connor: I don't plan on it. I just though it did that.. I played with it for hours that day.. and could have sworn that behavior existed.
04:44 PM Connor: Thought I missed something.
04:44 PM CaptHindsight: rs[m]: thanks, i didn't notice that
04:44 PM Connor: To be frank. I just want it to be a Kiosk setup. You boot it up, and it's in LinuxCNC.
04:45 PM Connor: No easy way to get to the shell without clicking a special button or something.
04:45 PM Connor: It's going to a nOOb and he doesn't need to be in the backend of the machine.
04:46 PM Connor: OH, The other thing.. this is the Beelink PC. I have it working on the 7i96, but, when I enable WiFi, it kills the ethernet. How do you set it up so that BOTH are active?
04:47 PM CaptHindsight: rs[m]: neat, Rpi4 over SPI to LPC17xx , so now we just need a LPC17xx board vs the Poopieboard
04:47 PM Connor: I use Ubuntu for daily driver, not debian + xfce, so.. I'm a bit clueless to the network stack.
04:48 PM rs[m]: CaptHindsight: i think it should be easily adaptable to anything running mbed
04:48 PM CaptHindsight: reads encoders as well
04:52 PM JT-Shop: a clean view port on the blast cabinet is a happy view port
04:52 PM Tom_L: Connor, can you set up a cron job for linuxcnc?
04:53 PM Tom_L: JT-Shop, now go dirty it up so it looks like you did something
04:54 PM JT-Shop: I'm done working for the day as soon as the pneumatic panel comes out of the PC oven
04:54 PM Tom_L: after all... cleanliness is next to laziness err....
04:54 PM JT-Shop: lol
04:54 PM Tom_L: how's the build going?
04:54 PM JT-Shop: a clean shop is the sign of a sick mind
04:55 PM JT-Shop: starting to powder coat parts and paint the frame, should start assembling Thursday
04:55 PM Tom_L: nice
04:55 PM Connor: Not sure I follow.. Cron job to do what? I can get it to startup on boot.. not maximize.
04:55 PM JT-Shop: I still need to wire up the panel but that don't take long on this kind of machine
04:56 PM Tom_L: Connor, sry i didn't catch that part
04:56 PM JT-Shop: I had to use devilspie for that on pukbuntu
04:56 PM CaptHindsight: Rpi + https://www.alibaba.com/product-detail/OM11043-598-RoHS-DEVELOPMENT-BOARD-LPC1768_1600168480453.html and some buffers and level shifters
04:56 PM Tom_L: Connor, https://forum.linuxcnc.org/49-basic-configuration/17021-emc2-auto-maximized-at-startup
04:59 PM JT-Shop: now that I use PyQtVCP things like turning off the cursor and starting maximized is simple...
04:59 PM Connor: I know JT-Shop.. I want to keep using Axis for this.. It's way more simple for the user at this point.
05:00 PM Connor: dang it.. BigJohnT's link for the .axisrc file isn't live now.
05:01 PM Connor: Oh.. there it is. :)
05:01 PM -!- #linuxcnc mode set to +v by ChanServ
05:06 PM JT-Shop: you could make a very simple screen in PyQtVCP
05:07 PM JT-Shop: for example https://github.com/jethornton/tkemc
05:09 PM Tom_L: JT-Shop, do they still have their group on riot for qtpyvcp?
05:10 PM JT-Shop: yeah but riot broke the link to freenode
05:10 PM Tom_L: i noticed
05:10 PM Tom_L: still fairly active?
05:10 PM JT-Shop: turboss tried to get it fixed a few times but they ignored him
05:10 PM JT-Shop: yeah
05:11 PM CaptHindsight: Tom_L: yes, I'm on there now
05:13 PM Tom_L: are they still modding probe basic?
05:13 PM Tom_L: maybe come up with some simpler examples for mill, lathe
05:14 PM drdoc: Connor: re: kiosk setup, the most current instructions I've seen are for Octoprint and friends
05:14 PM drdoc: don't have a link handy though
05:15 PM drdoc: Also, I think my pharmacy substituted ambien for my normal old-guy night meds
05:16 PM drdoc: I appear to have bought a monitor at 3:25am
05:17 PM CaptHindsight: Tom_L: they are still working on it
05:26 PM Lcvette: Tom_L: yo
05:29 PM CaptHindsight: <Tom_L> are they still modding probe basic?
05:29 PM Lcvette: yup
05:30 PM Lcvette: getting ready to hopefully push out a new release here shortly
05:30 PM Lcvette: trying to get the build bot working, turboss is working on it as we speak
05:30 PM JT-Shop: hey Lcvette how's it going?
05:30 PM JT-Shop: you need a deb!
05:30 PM Lcvette: JT-Shop: o/ hey JT!
05:30 PM Lcvette: deb?
05:30 PM Lcvette: :o
05:31 PM JT-Shop: a file to install with
05:31 PM Lcvette: for the build bot?
05:31 PM JT-Shop: no for probe basic
05:31 PM JT-Shop: https://jethornton.github.io/7i96/install.html
05:31 PM Lcvette: ah
05:32 PM Lcvette: let me check it
05:32 PM JT-Shop: you download the .deb and install with Gdebi
05:32 PM JT-Shop: simple and works out all the details
05:32 PM Lcvette: oh, we have installer
05:32 PM JT-Shop: https://github.com/jethornton/simple-pyqt5-deb
05:33 PM JT-Shop: a deb is better IMHO
05:33 PM Lcvette: probably better
05:34 PM Lcvette: but not easier
05:34 PM Lcvette: lol
05:34 PM Tom_L: for the user it probably is
05:34 PM JT-Shop: yeah for the user is simple
05:35 PM Lcvette: the linuxcnc install instructions for probe basic are one page and only a small amount of copy and paste
05:35 PM JT-Shop: gdebi resolves all the dependencies for you
05:35 PM Lcvette: and now the updater is working its easy to update your existing install
05:35 PM JT-Shop: installing a deb is one right click
05:35 PM Tom_L: can't get much easier than that
05:36 PM Lcvette: maybe turboss knows more
05:37 PM Lcvette: im not sure what this is used for
05:37 PM Lcvette: just installing dependencies?
05:37 PM Lcvette: or a complete probe basic installation?
05:37 PM CaptHindsight: easy to make debian packages!? What sort of magic is this? :)
05:38 PM Connor: having hard time getting both the wifi and ethernet up and running at same time on boot.
05:40 PM drdoc: Connor: I do all that with /etc/network/interfaces
05:40 PM drdoc: man 5 interfaces
05:40 PM drdoc: if the wpa_supplicant creds are set up you can use them in the interfaces file
05:40 PM JT-Shop: Lcvette, it would install probe basic and all it's dependencies
05:44 PM JT-Shop: CaptHindsight, yeah I finally nailed down making a deb very easy... there are so many tools out there that are crap it took me 6 months to wade through them and figure out the simple way
05:44 PM Lcvette: JT-Shop: by what method of install?
05:45 PM JT-Shop: best of all you don't need peep or pep or pip
05:45 PM Lcvette: im still lost
05:45 PM Lcvette: lol
05:45 PM JT-Shop: you right click on the .deb and open with Gdebi
05:45 PM Lcvette: that might eb a good thing then for the dev install
05:45 PM Lcvette: for the user install i think the on screen installer is probably a bit more user friendly
05:45 PM JT-Shop: Gdebi resolves all dependencies
05:46 PM Lcvette: yeah that would certainly be good for dev install
05:46 PM Lcvette: its much more cumbersome
05:48 PM JT-Shop: we had a nice ride the other day in the C5, I'm so glad winter is done
05:48 PM Lcvette: yeah, hows the pollen there?
05:49 PM Lcvette: we live in a yellow world here right now
05:49 PM Lcvette: lol
05:49 PM JT-Shop: I"ve not noticed it except for some huge things falling off some trees
05:49 PM Lcvette: pine trees really kick out the stuff here
05:50 PM JT-Shop: I have mostly oak and hickory and walnut with a few pine and some cedar and juniper
05:54 PM JT-Shop: frame for the machine I'm building https://gnipsel.com/images/customers/Foxy/Top%20Cutter/top-cutter-01.jpg
05:56 PM Lcvette: JT-Shop: what kind of frame?
05:56 PM Lcvette: * JT-Shop: what kind of machine is that frame for?
05:58 PM JT-Shop: it automates a late 1800's spoke lathe
05:59 PM Lcvette: nice!
05:59 PM Lcvette: documenting it anywhere?
06:00 PM JT-Shop: https://gnipsel.com/images/customers/Foxy/20201022_132909.mp4
06:00 PM JT-Shop: https://gnipsel.com/images/customers/Foxy/
06:02 PM JT-Shop: that video is the first one I did
06:02 PM Lcvette: very cool!!!
06:02 PM CaptHindsight: 21st century solution for 19th century product
06:03 PM JT-Shop: yeah it's a fun puzzle to figure out
06:03 PM JT-Shop: Defiant quit making those machines when WW1 started
06:03 PM CaptHindsight: JT-Shop: do they just make wooden wheels or the whole carriages?
06:03 PM * JT-Shop wanders inside
06:04 PM JT-Shop: they (the guy I'm building the machines for) makes all kind of handles and tools
06:04 PM CaptHindsight: oh I though it was spokes
06:04 PM CaptHindsight: maybe that is another project
06:05 PM JT-Shop: the machines were spoke lathes
06:05 PM CaptHindsight: ah ok
06:05 PM JT-Shop: for wagon wheels but they have been converted to modern use
06:05 PM CaptHindsight: should be handy for custom staircases
06:05 PM JT-Shop: there is a place in Ky that makes wagon and cannon wheels
06:18 PM JT-Cave: CaptHindsight, they are a bit time consuming and tedious to setup so more suited to production runs
06:56 PM Tom_L: https://twitter.com/4jawjan/status/1382098856922521605
06:56 PM Tom_L: everybody needs one of those in their drawer
06:58 PM drdoc: zowie
07:00 PM Tom_L: list for $1267 on sale for $659
07:01 PM drdoc: I believe it. What thread is that?
07:01 PM Tom_L: 4" x 8 npt
07:01 PM drdoc: aw man
07:01 PM Tom_L: might be a 2 man job to turn the wrench
07:02 PM drdoc: I've smeared a ton of pipe dope on that thread
07:02 PM drdoc: and torqued it up with 60" pipe wrench
07:02 PM drdoc: as you say, not alone
07:03 PM drdoc: the company I worked for stopped supplying those pipe wrenches per rig - they disappeared a lot
07:04 PM drdoc: when the tool pusher shows up with one, everybody cries
07:30 PM Connor: .axisrc add root_window.attributes('-fullscreen', True)
07:30 PM Connor: best way to do fullscreen (not maximized)
07:31 PM Tom_L: figured it out ehh?
07:31 PM Tom_L: where is that file?
07:32 PM Connor: in your home directory
07:33 PM Tom_L: k
07:33 PM Tom_L: hidden?
07:37 PM Connor: Doesn't exist. You make it.
07:37 PM Connor: and yes.. the . in front will hide it.
07:37 PM Tom_L: ahh ok, good to know

10:00 PM XXCoder: https://www.aliexpress.com/item/1005002360295533.html
10:00 PM XXCoder: interesting
10:01 PM XXCoder: very high rpm, wonder if would be best for circuit board engraving or whatever
10:04 PM CaptHindsight: the bodies have 35k and 45k on them but the ad says 350k and 450k
10:05 PM XXCoder: chineseium ratings lol
10:05 PM CaptHindsight: Chinese exuberance
10:07 PM Rab: I have an air-powered dental handpiece I've used for PCB drilling. The biggest drawback is that you are limited to one shank size, and it's typically 1/16". So that rules out 1/8" shank carbide PCB tooling, which is basically everything you would want to use.
10:08 PM XXCoder: interesting
10:08 PM Rab: I used 1/16" shank dental burs, and they dropped through FR4 like butter. (And went sideways just as easily.)
10:12 PM drdoc: XXCoder: if that's the same Marathon that makes 3ph motors, they're probably good quality
10:12 PM Rab: The handpieces are apparently made in Korea.
10:12 PM drdoc: but if your PCB has more than 3 through hole components, drill the damn thing CNC
10:12 PM XXCoder: sometimes they make seconds and sell em out of same factory as real ones
10:13 PM Rab: drdoc, dpm
10:13 PM drdoc: dpm?
10:13 PM Rab: drdoc, don't tell me what to do.
10:13 PM drdoc: lol
10:13 PM * drdoc has hand-drilled some 400-500-hole boards
10:14 PM Rab: I haven't drilled a board in a long time, I just get them fabbed now.
10:14 PM drdoc: I make one once in a while
10:14 PM * Bleepshop does the Happy Dance.
10:14 PM Rab: But I did make a special precision drill press because I was dissatisfied with free-handing the dental drill.
10:14 PM drdoc: Rab: I'm moving in 3 months, so any 220V will be a pirate mod
10:15 PM Rab: drdoc, clothes dryer outlet?
10:15 PM Bleepshop: Z is tested and sounds good. Need to finish mounting the controller cabinet and wiring the table now.
10:15 PM drdoc: there is not one single 220V circuit inside this house
10:16 PM XXCoder: theres interesting dermel drill press design on thingverse
10:16 PM XXCoder: its made for drilling small holes
10:16 PM drdoc: XXCoder: I used a chinesium "precision" press off Amazon, cost about $80
10:17 PM Rab: http://reboots.g-cipher.net/pcbdrill/
10:17 PM XXCoder: found it. https://www.thingiverse.com/thing:4148260
10:18 PM XXCoder: it looks like normal press drill but small lol
10:18 PM drdoc: I gotta look at the panel outside but I expect I'll just stick a 220V breaker in the garage panel and run it 8" to a twist-lok box
10:19 PM Bleepshop: Rab: 56K RPM, 1/8" collet, $30. https://www.harborfreight.com/pneumatic-18-in-micro-die-grinder-kit-60244.html
10:19 PM XXCoder: video shows it cutting steel
10:19 PM XXCoder: https://youtu.be/A6iSEkNZZyc
10:20 PM Rab: Bleepshop, here's a nice little design which uses that die grinder: https://www.instructables.com/%2430-High-Speed-PCB-Drill-Press/
10:20 PM CaptHindsight: I have to control four 5-axis machines that will work on the same part at the same time with LCNC
10:20 PM drdoc: Bleepshop: all due respect, I'm not holding *anything* from HF in my hand at 56krpm
10:20 PM drdoc: XXCoder: this one:
10:20 PM drdoc: https://smile.amazon.com/gp/product/B0058ECQX2
10:20 PM drdoc: price has gone up
10:20 PM XXCoder: nice indeed. printed one should be very cheap though
10:21 PM Bleepshop: drdoc: That's the respect they're due, mount them in a tool or wear a heavy glove. LOL
10:21 PM drdoc: zackly
10:21 PM drdoc: Foredom makes some 150krpm die grinders
10:21 PM drdoc: Not Cheap.
10:22 PM drdoc: Rab: I got that 700W 48V PSU for $45 shipped
10:22 PM Bleepshop: drdoc: I've got a gen 1 Shapoko that I'm going to hang one of those on for doing PCBs.
10:22 PM Rab: drdoc, nice.
10:22 PM drdoc: ah, yeah
10:22 PM drdoc: Bleepshop: I use my elder Foredom for that
10:23 PM drdoc: on my shop-built machine
10:23 PM Bleepshop: drdoc: I've also got a 36"x48" chunk of 3/8" polycarbonate for a scatter shield just in case. :D
10:23 PM drdoc: there ya go.
10:24 PM drdoc: I *knew* I had a use for this teller window!
10:24 PM drdoc: Seriously, I bought a 1" bulletproof teller window on a whim awhile back
10:25 PM drdoc: it was $6 at auction
10:25 PM Bleepshop: Leftovers from re-doing a 'Shatter-Proof' basketball backboard. Took the kids a month to kill the original and the replacement is still there 10 years later. It's just turning a lovely shade of purple. LOL
10:25 PM drdoc: and.... I think the noise we just heard was my 18/4 shielded wire being dropped off
10:26 PM drdoc: Are any of y'all using a Dust Deputy? or one of the clones?
10:27 PM drdoc: and do you have any opinion concerning a mister vs forced air?
10:28 PM Bleepshop: drdoc: I'm using a Frankenstein composed of a 30gal blue poly barrel, a drum shell and some 2" PVC bits.
10:28 PM drdoc: nice
10:28 PM drdoc: honestly a curbside recycled Bissel house vac is doing a decent job
10:29 PM drdoc: one of the cyclone models
10:29 PM drdoc: but I doubt that'll last long
10:29 PM drdoc: Bleepshop: did you see that dust shoe I posted the other day?
10:29 PM Bleepshop: Yeah, It's a lock-lid barrel with a ring and I took the original hardware that held the head on the musical drum off and moved it up to hold the shell to the lid.
10:30 PM Bleepshop: Nope, been busy dealing with RL and havent had time to do shit in the shop for a few days.
10:31 PM drdoc: https://www.cnczone.com/forums/diy-cnc-router-table-machines/374424-david-new-2x3-bench-top-cnc-5.html
10:31 PM drdoc: the upper manifold is a bit over the top, but I like that open concept
10:32 PM Bleepshop: drdoc: I've got a local source for these cheap. Some of them smell like really pungent herbs or mint since I get them from a herbarium. https://images-na.ssl-images-amazon.com/images/I/714BUKncmAL._SL1500_.jpg
10:33 PM drdoc: that's just about prefect for... well, everything
10:33 PM drdoc: 30 gallons is a good size
10:36 PM Bleepshop: Nice shoe! :D
10:37 PM drdoc: I think I'm going to try a scaled-down version
10:37 PM Bleepshop: Yeah, I like it because a 42gal bag fits perfectly and since everything is through the lid i can pop it off and use it for a cleanup can as well.
10:37 PM drdoc: shame you're not in austin
10:37 PM drdoc: :-)
10:38 PM Bleepshop: Way up the Pecos River from you. LOL
10:38 PM drdoc: NNNNG
10:40 PM drdoc: I ordered this the other day:
10:40 PM drdoc: https://smile.amazon.com/gp/product/B07WFX3FZ5
10:41 PM drdoc: it came in, for once the box wasn't all beat up and it was on time
10:42 PM Bleepshop: Less than 50 miles from the headwaters or a 5 minute drive to go throw rocks in it as a matter of fact.
10:42 PM drdoc: So I open the (factory-sealed) Siverstone retail box and find...
10:42 PM drdoc: https://www.amazon.com/dp/B005NN3C3G
10:42 PM drdoc: somebody went to some serious effort to do that
10:44 PM drdoc: anyhow
10:44 PM drdoc: I'm gonna stop carping and go wire some motors
10:44 PM drdoc: hasta, y'all
10:44 PM Bleepshop: I'm running on all industrial and commercial retreads here. Machine to my left that's my minidlna server used to be a Vigor Systems / REELZ channel content delivery box I picked up as scrap.
10:45 PM Bleepshop: Yeah, I've got a control cabinet to hang and a table to wire as well.
10:50 PM Tom_L: all part of the fun

11:28 PM mrec_: is anyone sharpening carbide inserts?
11:29 PM XXCoder: isnt that require precision grinder
11:29 PM mrec_: it seems like that was one of the factors to get carbide work with a mini lathe
11:29 PM mrec_: just a normal grinder
11:30 PM mrec_: I'm grinding it ... the chinese carbide are weaker than the korloy ones
11:30 PM XXCoder: interesting
11:31 PM mrec_: korloy needs a lot grinding to get a little bit off, the chinese ones are relatively quick
11:31 PM mrec_: but both of them can go through steel
11:32 PM mrec_: easy parting needs CNC on a mini lathe however.. it requires some attention when doing it manually.
11:32 PM mrec_: I broke 10 korloy before I figured out how it works... it's not just driving the carbide into the steel
11:33 PM mrec_: poor korloy I should have got chinese ones (lower quality) first and then switched to korloy
11:33 PM XXCoder: you meanie
11:33 PM XXCoder: heh
11:34 PM mrec_: if you grind it you will quickly feel the difference.
11:40 PM XXCoder: cheaper alloying i guess
11:42 PM veegee: HSS is quite suited for lathe tools
11:42 PM mrec_: I'm fine with carbide works well
11:42 PM veegee: I love that you can just keep sharpening them over and over in a second
11:42 PM veegee: Yeah I have lots of carbide insert tools too
11:43 PM mrec_: there's just some learning curve I only have that lathe for 1 week... I never seriously used a lathe before
11:43 PM roycroft: mrec_ has a tiny lathe with virtuall no mass and the rigidity of a wet noodle
11:43 PM mrec_: but I'm fine with it :-)
11:43 PM roycroft: it is a fine machine
11:43 PM mrec_: it cuts 30mm like butter if you do it the right way
11:43 PM roycroft: but it is not a good match for carbide tooling
11:43 PM mrec_: steel
11:44 PM mrec_: it is if you have experience with it..
11:44 PM veegee: HSS holds a very fine edge
11:44 PM mrec_: just need to follow some rules.
11:44 PM roycroft: you have had yours for a week
11:44 PM roycroft: i had mine for a decade
11:44 PM mrec_: it depends on the use case as well.
11:44 PM mrec_: mine will be converted to CNC soon
11:45 PM roycroft: hss can be ground to a much finer edge than carbide
11:45 PM veegee: Carbide tools do need a rigid machine to work properly
11:45 PM mrec_: I was talking with a guy who does turning work for his entire life he never made spur gears.
11:45 PM veegee: Or they tend to chip
11:45 PM mrec_: rigidity is not a problem of my mini lathe
11:45 PM veegee: HSS holds a razor sharp edge which is better for smaller machines
11:45 PM roycroft: i'd wager that most machinists these days have little or no experience cutting gears
11:46 PM mrec_: jamming chips are the only problem if you find out how to solve that you're good to go with carbide (for parting).
11:46 PM veegee: If your machine is rigid enough, you can go at your workpiece with a rusty butter knife
11:47 PM mrec_: I'd like to have a 100k CNC turning/milling machine... but for now I have to stay with a 560$ lathe and 780$ mill..
11:47 PM mrec_: most of the gear work was making fixtures to swap the discs..
11:48 PM mrec_: parting is still a problem for me since it needs my attention, I want to push a button and the machine should do it by itself.
11:48 PM mrec_: then I can ramp up my gear factory :D
11:50 PM veegee: There is a middle ground, you don't need $100k for a nice machine
11:50 PM veegee: $4,000 will get you a solid mill or lathe
11:51 PM mrec_: I still need to swap discs manually from the lathe to the A axis of the milling machine to the horizontal rotary table (for the mounting holes)
11:52 PM mrec_: a 5th axis could eliminate one step on the milling machine
