04:41 AM Tom_L: morning
04:41 AM Tom_L: 27°F High 42°F
04:41 AM mrec: Tom_L: did you ever use a boring head?
04:41 AM mrec: I wonder is a single side boring head worth it?
04:41 AM Tom_L: depends how much you plan to use it
04:41 AM Tom_L: as a hobby probably not
04:41 AM Tom_L: what do you mean, single size?
04:41 AM Tom_L: they usually have a micrometer built in for adjustments
05:05 AM mrec: I'm playing around with some bearings and yes that's where i have the problems with my CNC ~0.05 - 0.1mm tolerances
05:10 AM mrec: well I ordered one of those chinese boring heads ... let's see how it turns out
05:13 AM JT-Cave: morning
05:17 AM JT-Cave: I found a bug in PyQt6 uic and reported it yesterday on the mailing list and it's been fixed... I wonder how long it takes to get to debian lol
05:52 AM Scopeuk: I guess ask your grand children to let you know?
05:58 AM solarwind: Well Debian is one of the few distributions that's always been very reliable. They do things that way for a reason. You can always use unstable
06:03 AM Scopeuk: completely agreed
06:03 AM Scopeuk: Debian prioritise stability above everything. it's great that exists but it does come at the cost of new/updated packages taking a long time
06:03 AM solarwind: I do like the predictability of Ubuntu though
06:04 AM solarwind: the thing about distributions is that.... fuck I have work today why have I not even slept yet.... anyway
06:04 AM solarwind: the core of the OS should be rock solid stable
06:04 AM solarwind: along with core system libraries
06:05 AM solarwind: for the rest of the user applications packages, you can get by with what the authors or package maintainers consider stable
06:05 AM solarwind: the windows/mac os model works really well
06:05 AM solarwind: nixos / nix package manager is very good
06:06 AM solarwind: on mac os, I use homebrew for the latest user/development packages but the core of the OS is rarely updated
06:07 AM solarwind: I think Linux distributions need to be less about packaging every piece of software out there and try to standardize on a model that more of the original authors can work with and it's been moving in that direction
06:08 AM solarwind: if I'm writing a general purpose application, it's a lot easier for me these days not to worry about what distribution anyone is using because the core OS facilities are more standard thanks to freedesktop.org and similar
06:08 AM Scopeuk: I think there is slightly more inertia on linux than under windows and osx as more of the open packages tend to properly make use of shared dependencies (and the package managers make use of it). you end up with an integrated stack rather than an integrated os and then hodge podge software ontop
06:08 AM solarwind: systemd is a dogsend, I don't understand why some people hate it so much...
06:09 AM solarwind: that's the thing, that made sense 20 y ears ago when computers had < 64MB of RAM
06:09 AM solarwind: these days, it doesn't matter if you have a thousand copies of your own libc in memory
06:10 AM solarwind: you don't NEED to worry about what shared libs the OS provides because the penalty of static linking or providing your own libs is next to zero
06:10 AM Scopeuk: the systemd thing I think is largely inertia and that it is differnt is enough to upset people. it does bring some things into one block that used to be separate and if that is to you a benefit or a disadvantage will depend on how you are using it. My impression of it is that for most people it is an improvement
06:10 AM solarwind: and C/C++ have a rock solid stable ABI
06:10 AM solarwind: I think it's a _vast_ improvement. If it gets more people using Linux, the more momentum and resources and attention it's going to get
06:11 AM Scopeuk: the C ABI or why every programming language uses a bit of C heritage weather it likes it or not
06:11 AM solarwind: Valve basing steam OS on it is a HUGE win
06:11 AM solarwind: well the C calling convention is just a natural evolution of how the stack is used
06:12 AM solarwind: but C++ didn't have to go that route, they just chose to
06:12 AM solarwind: that's why it's a non issue that every other language changes ABI, but every other language also has its own package manager and can easily instantly recompile perfectly every time
06:13 AM solarwind: but C++ tends to push people into using binary libs provided by OS packages, which is why they now have to make ABI stability a huge deal
06:16 AM solarwind: if I'm writing C/C++, I tend to use conan or vcpkg so I don't have to worry about the target having any of those libraries available
06:16 AM solarwind: I can just ship a single binary+libs fully vendorized like any other language and it'll just work
06:17 AM solarwind: same with compiling, the target just needs a compiler toolchain. no need to install any -dev packages on the target before compiling.
06:18 AM solarwind: Well these days I use Rust and Zig. Rust works that way out of the box, its "cargo" package manager handles everything
06:23 AM Tom_L: JT-Cave, https://www.youtube.com/watch?v=Lonf4ypINVM
06:24 AM JT-Cave: SWEET
06:25 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Spring/Coil_spring7.jpg
06:25 AM JT-Cave: nice tight coils
06:25 AM Tom_L: he was happy
06:25 AM solarwind: Very nice
06:29 AM Tom_L: i had to add a little more travel on his because his wire was a little stiffer and had more spring back
06:41 AM JT-Cave: http://www.opengl-tutorial.org/download/
06:41 AM JT-Cave: I like that license
06:47 AM Scopeuk: MIT in fewer words
06:48 AM Scopeuk: it does fail to disclaim responsibility for how much that would stand up
06:48 AM Tom_L: :)
06:49 AM Tom_L: Scopeuk, it's in the fine print
06:59 AM JT-Cave: 29°F High: 42°F Partly Sunny
07:13 AM JT-Cave: rooster says time to start your chicken day
08:46 AM travis_farmer: pretty quiet this morning...
08:48 AM JT-Shop: fire #1 started
08:50 AM travis_farmer: i can almost feel the heat from here... ;-)
09:03 AM JT-Shop: I don't feel any... the fire went out
09:04 AM travis_farmer: well heck... i hate when that happens...
09:06 AM travis_farmer: this dang fatigue sucks... can't do anything but what i get winded...
09:30 AM Tom_L: JT-Shop, pour some gasoline on it, that'll bring it right back to life quick
09:31 AM travis_farmer: lol
09:31 AM Tom_L: i was lighting a fire in the pit the other day and used a little charcoal lighter. it was so cold it didn't even want to burn
09:32 AM Tom_L: not warm enough to vapor i guess
09:47 AM Tom_L: so we found out yesterday that in grbl S0 M3 turns the spindle on
09:47 AM Tom_L: unlike linuxcnc
09:47 AM Tom_L: that should be a NO NO
10:12 AM Roguish: good morning....
10:22 AM roycroft: hello
10:23 AM roycroft: our new forecast is out: showers, interrupted by periods of rain, for the forseeable future
10:24 AM Roguish: here it's showers with on/off rain all week.
10:24 AM Roguish: NOAA seems to change every few hours
10:24 AM roycroft: at least it's not cold and snowy
10:24 AM Roguish: there
10:24 AM Roguish: s a cold front coming down the coast
10:26 AM Roguish: Cale Yarborough died...... .he was pretty good.
10:26 AM roycroft: yeah, i heard that
10:27 AM Roguish: his father was a rum runner
10:27 AM Roguish: moonshiner
10:28 AM roycroft: i've never been a big fan of car racing, especially nascar, but i remember cale yarborough as a great racer and a decent guy
10:29 AM Roguish: I used to be, back then. no now
10:30 AM roycroft: he was a household name in the '70s
10:30 AM Roguish: with the Unsers and Allison, and Andretti
10:30 AM roycroft: yeah i remember all of them
10:31 AM roycroft: that was back before nascar was politicised
10:32 AM roycroft: well, hyperpoliticised
10:33 AM bjorkint0sh: nascar: merry go round for grown ups.
10:33 AM bjorkint0sh: scratch that.
10:33 AM bjorkint0sh: motor racing: merry go round for grown ups.
10:35 AM roycroft: driving fast does not give me a thrill like it does some folks
10:36 AM bjorkint0sh: the point is to do it faster than all the other kids on the merry go round.
10:36 AM bjorkint0sh: not just fast.
10:36 AM bjorkint0sh: requires an audience.
10:39 AM roycroft: my real estate agent has a sports car, and likes to drive really fast
10:40 AM roycroft: when i'm riding with him for house showings i have to remind him often that not all of us enjoy that
10:41 AM roycroft: i have no problem with them that do, as long as i'm not riding with them
10:42 AM bjorkint0sh: I understand. It's a needless risk.
10:42 AM roycroft: well a lot of things in life entail risk
10:42 AM roycroft: i'm not anti-risk
10:43 AM roycroft: but the risk-benefit ratio is not there for me when it comes to driving fast
10:44 AM roycroft: it's even more than doing nothing for me
10:44 AM bjorkint0sh: I find it a needless risk and I can't fathom why I used to do more than 90 on my way to work a few years back.
10:44 AM bjorkint0sh: the time gained is minimal.
10:44 AM roycroft: it's a negative - i enjoy watching the scenery as i drive/ride
10:44 AM roycroft: and if i'm going really fast i don't get to see it as well
10:44 AM roycroft: so it's actually less enjoyable than driving slowly
10:45 AM Unterhaus_ is now known as Unterhausen
10:46 AM Unterhausen: I used to have a relatively fast car and it was fun. Now I'm perfectly happy with my prius. Fast cars are a good way to develop road rage
10:48 AM roycroft: i love my prius - it's economical, reliable, and comfortable
10:48 AM roycroft: it's also really quiet
10:48 AM roycroft: but i also love my f350 - it's big and powerful and has 4wd
10:49 AM roycroft: i can haul stuff in it that i can't with my prius, and go places the prius can't
10:49 AM roycroft: i've had the f350 for almost a year and a half now, and have put less than 1000 miles on it
10:50 AM Roguish: prius ???? lolol
10:50 AM roycroft: i drive it more than i need to because it's good for the engine to run regularly
10:50 AM Roguish: girlyman car
10:51 AM roycroft: girlyman drove a camper van
10:51 AM roycroft: they weren't big enough for a tour bus
10:52 AM roycroft: but the camper van got them to their gigs with all their gear
10:52 AM roycroft: i don't think a prius would have done that
10:52 AM Unterhausen: watch the people that get out of big pickups at the gas station. I don't agree with the term girlyman, but pickup drivers are insecure about their own sexuality
10:54 AM bjorkint0sh: Roguish, what do you think of small hondas? also the same category as priuses?
10:54 AM Unterhausen: funniest thing I saw recently was someone struggling to put something in the back of their pickup at lowes. Tonneau cover never comes off of that thing and my prius has more carrying capacity
10:54 AM Unterhausen: all the loaders were out there helping
10:56 AM Tom_L: are we categorizing drivers this morning??
10:56 AM Tom_L: :)
10:56 AM bjorkint0sh: I am a speed limit driver of a small Dollar General car.
10:57 AM bjorkint0sh: I call it that because I see at least 10 of the same thing everywhere I go.
10:57 AM Tom_L: bjorkint0sh, at least it's not from Harbor Freight
10:57 AM bjorkint0sh: came out of a store one day and saw someone driving off in my car. brief panic. realized it was parked next to mine.
10:57 AM bjorkint0sh: stupid thing was identical to the scratches and cracks.
10:59 AM bjorkint0sh: Tom_L, hahah. yes.
10:59 AM bjorkint0sh: but I believe there are more Dollar Generals than Harbor Freights.
11:00 AM Tom_L: we've got 3-4 different 'Dollar General' types around here
11:00 AM roycroft: so a friend of mine who was over on new year's even gifted me a bottle of manx sprits
11:01 AM roycroft: if any of you are scotch drinkers i highy recommend trying it, if you can get it
11:01 AM bjorkint0sh: Tom_L, Honda Accord.
11:01 AM roycroft: he imported it from the uk - i don't know if there are any us distributors
11:01 AM bjorkint0sh: most stolen vehicle in the country.
11:01 AM bjorkint0sh: #2 being the civic.
11:01 AM bjorkint0sh: or is it the other way around?
11:01 AM roycroft: what they do is import scotch whisky, redistill it, separating the fractions, and reblend without all the fractions
11:02 AM roycroft: it ends up with the good flavors concentrated, the alcohol heat removed (it's 80 proof, and they start with 120 proof whisky), and the color removed
11:03 AM Tom_L: bjorkint0sh, i thought it was the civic
11:03 AM Tom_L: hmm
11:03 AM roycroft: they have a patent on part of the redistillation process, and part of it is a trade secret
11:03 AM roycroft: i thought it was the civic as well
11:04 AM bjorkint0sh: I forget. Dollar General vs Dollar Tree
11:04 AM Tom_L: i had 3 civics but down to one now as the boys wanted trucks
11:04 AM roycroft: i had a civic for a few years
11:04 AM Tom_L: i don't mind driving them but they're a bit hard getting in and out of for us ole pharts
11:05 AM Tom_L: easy to park
11:06 AM roycroft: yeah, you can park a civic just about anywhere
11:14 AM CaptHindsight: https://manxspirit.com/distilling-process/
11:16 AM CaptHindsight: "malt whisky head note, a floral quality and some sweet, grassy notes" sounds like it's missing some of the good parts and keeps some of the bad parts
11:29 AM roycroft: it does seem like they started with a speyside whisky, not an islay or even highland
11:29 AM roycroft: but there are some good speyside whiskies
11:30 AM Unterhausen: I thought Kia was the most stolen car in the U.S., because of tiktok
11:30 AM Scopeuk: and a total lack of modern security measures
11:30 AM roycroft: looks like governor abbot sent you a gift last night, capthindsight
11:30 AM Tom_L: honda has been here longer
11:31 AM Scopeuk: granted that's not specifically a kia thing, can you still unlock and start Mercedes from the can bus on the wing mirrors?
11:31 AM Scopeuk: and some of the old rolls royce cars can be unlocked by blowing air into the door locks
11:32 AM Unterhausen: a lot of cars can be broken into and started with electronics, but kias can be started with a usb connector
11:39 AM roycroft: there's not much of a market for a stolen rolls
11:39 AM JT-Cave: I returned the fiberglass resin and I'm just not going to put any finish on the steam box
11:39 AM roycroft: they're pretty conspicuous
11:39 AM roycroft: and not the type of vehicle that one would part out
11:40 AM roycroft: what's the steam box made of?
11:40 AM roycroft: if it's a marine plywood, it should probably do fine without finish
11:40 AM roycroft: just don't use hide glue to hold it together
11:41 AM CaptHindsight: roycroft: I haven't been in the city in months. I just noticed that they have a new mayor
11:41 AM JT-Cave: a mix if white pine and red oak
11:41 AM JT-Cave: used titebond iii
11:42 AM JT-Cave: the pot adapter is white pine the top is red oak
11:42 AM roycroft: yeah, that will probably be fine
11:42 AM Tom_L: white pine might give you a bit of grief
11:42 AM roycroft: titebond iii might get a bit soft
11:42 AM roycroft: i would use some screws in it as well
11:43 AM roycroft: the pine might seep some resin when it gets hot
11:43 AM roycroft: but if the parts are suspended in the steam box that should not be a problem
11:46 AM roycroft: my panel raising cutter is out for delivery, finally
11:46 AM roycroft: whether the postal service actually deliver it today or not remains to be seen
11:47 AM roycroft: of late, the typical behavior is for a parcel to be out for delivery, not show up that day, and then finally be delivered the following day
11:47 AM Unterhausen: the people that steal kias mostly drive around for fun and wreck them, from what I can tell
11:48 AM Unterhausen: cold easily do the same thing with a rolls, but they are harder to find. Even the foreign grad students don't buy them
11:48 AM * JT-Shop knows what a box looks like after a trip to Australia and back now
11:49 AM Unterhausen: the most rolls-like car I have seen in town was an audi limo, and that was unusual
11:49 AM roycroft: a rolls is usually not as accessible as a kia when it comes to stealing one
11:50 AM roycroft: you don't usually see a rolls in the mall parking lot
11:50 AM Unterhausen: I have a crummy original shapeoko, I'm thinking about driving it with a grbl shield from a 7i96
11:50 AM roycroft: and often, when they are out in the wild, they are attended
11:50 AM Tom_L: yeah just bentleys at the mall
11:50 AM Tom_L: :)
11:51 AM Unterhausen: we had friends with a bently when I was a kid, it was almost always in the garage
11:51 AM JT-Shop: I should go start another fire
11:51 AM JT-Shop: my neighbor had a bug eyed sprite
11:51 AM Tom_L: JT-Shop, quit making puny fires!! give it some gusto
11:51 AM Unterhausen: I wouldn't want to drive it either
11:52 AM Tom_L: i know it was cold yesterday since the shop never really got comfortably warm
11:52 AM Unterhausen: I know it's cold enough because I want to go out in the garage and make bike frames
12:03 PM Unterhausen: I got some parts from send cut send. They put big orange "rush" stickers on the outside so my wife would be alarmed
12:04 PM Unterhausen: parts are nice, but I wanted some 8mm clearance holes and designed them with 6mm clearance holes. For some reason the mounting nuts for the extrusion I'm using are much cheaper for 8mm screws
12:05 PM roycroft: did she run them out to you as fast as she could?
12:07 PM Unterhausen: the main consequence was she thought I was wasting money on postage, but didn't say that
12:17 PM Unterhausen: I've been really happy with SCS, hopefully they didn't expand too much
12:18 PM Unterhausen: I really wanted to get them to bend me some parts, but I didn't want to wait
12:22 PM Unterhausen: Tom_L nice job on the spring bending. I want to bend some springs, I'll have to think about copying your method
12:22 PM Unterhausen: I would have commented on your video, but youtube told me you had banned me
12:22 PM roycroft: the only springs i've ever made are a lot bigger than that
12:22 PM roycroft: and i had to bend them by hand, and that was both difficult and did not work out as nicely as i'd like
12:22 PM roycroft: they are functional, but not pretty
12:23 PM Tom_L: Unterhausen, i'm not real YT fluent and go with the default settings so who knows what happened
12:23 PM Unterhausen: I was exaggerating, you seem to have turned off comments
12:24 PM Tom_L: i thought comments were on by default but maybe not
12:24 PM Unterhausen: maybe it's a setting
12:24 PM Tom_L: it is but i thought it was default on
12:24 PM roycroft: comments are turned off, yes
12:24 PM Unterhausen: I think the springs I need are smaller than the ones you made
12:25 PM Tom_L: use smaller pins
12:25 PM JT-Shop: I made one from 0.015" spring wire about 3 times until I got it right
12:25 PM JT-Shop: nap time here
12:25 PM Tom_L: i could go for another one :)
12:26 PM Unterhausen: I want to make ones like the ones in these kits, sorry about the popover https://www.renehersecycles.com/shop/equipment/bolts/replacement-hardware-for-compass-and-mafac-centerpull-brakes/
12:27 PM Tom_L: just updating for 'all comments allowed'
12:27 PM Tom_L: we'll see
12:27 PM Tom_L: those look pretty easy to do
12:27 PM Unterhausen: Okay, I'll go troll the video now
12:27 PM Tom_L: dunno how slow they update..
12:28 PM Unterhausen: except for the long tail bend, they are really close to what you made
12:28 PM Tom_L: that's easy enough
12:28 PM Tom_L: ccw helix and the little tool i did
12:29 PM Tom_L: helps guide the wire past the first loop
12:29 PM Unterhausen: I was just thinking you could have the tool pull the tail over another post and then bend it
12:29 PM Tom_L: you could but you'd have to insert it after winding
12:29 PM Tom_L: an M0 would take care of that
12:30 PM Unterhausen: I guess you really need 3 axis for your method, hard to make a dedicated machine
12:31 PM Tom_L: mmm still says comments are off
12:32 PM Tom_L: maybe the 'it's made for kids' keeps it off
12:37 PM Unterhausen: It might
12:39 PM Tom_L: i'll set that one and see
12:40 PM Tom_L: see what it does now
12:41 PM Tom_L: yeah that was it
12:41 PM Unterhausen: great.
12:41 PM Tom_L: i don't check often anyway
12:43 PM Unterhausen: you'll probably get an email if I comment
12:43 PM Unterhausen: how did you make the initial bend?
12:43 PM Tom_L: pliers
12:44 PM Unterhausen: figured
12:44 PM Unterhausen: I tend to overcomplicate things and not get started as a result
12:46 PM Tom_L: it must have been on for a while because a couple did get some comments
12:49 PM HwT: Hi guys, does anybody know any resources to get a touch screen display for linuxcnc, i know there are some POS systems you can repurpose the display. Just asking to see if anybody know some good candidates for use :D
12:50 PM Tom_L: Unterhausen, you could wind square springs if you wanted :)
01:09 PM bjorkint0sh: https://www.youtube.com/watch?v=4pK3O43Jddg
01:25 PM roycroft: most of the more common touch screens work out of the box with debian
01:25 PM roycroft: so you probably won't have a problem with that part
01:26 PM roycroft: regarding linuxcnc, just use touch or some other touch screen interface when you launch it, once you've confirmed that the operating system is happy with it
01:36 PM JT-Shop: most touch screens work with Linux now
01:37 PM JT-Shop: https://www.amazon.com/gp/product/B01N4U7E7H
01:37 PM * JT-Shop has phase 1 done of the great chicken gathering... so time to pretend to work
01:41 PM JT-Shop: step 1 clear off the plasma table
01:58 PM Tom_L: sounds pretty serious
01:59 PM XXCoder: is it water type?
01:59 PM roycroft: well my cutter has arrived, and early (the mail normally does not get delivered until early evening)
01:59 PM Tom_L: roycroft, new years resolutions n all....
01:59 PM roycroft: so maybe the usps have made a new year's resolution to be efficient again
02:01 PM roycroft: and i have another half hour of my lunch break
02:01 PM roycroft: just enough time for a test cut
02:01 PM * JT-Shop takes five with Leo
02:02 PM XXCoder: ohh clickspring video looks good
02:20 PM XXCoder: and it was!
02:25 PM bjorkint0sh: XXCoder, I loved every minute of it.
02:25 PM XXCoder: indeed
02:25 PM bjorkint0sh: of course lathes existed in ancient egypt. just blew my mind!
02:25 PM XXCoder: yeah lathes is thousands of years old
02:26 PM XXCoder: 5,000 or so roughly
02:26 PM bjorkint0sh: I mean, I bemoan my lack of a shop but 2000 years ago they didn't give a shit. they just made one.
02:26 PM bjorkint0sh: 2000 years ago. what's my excuse.
02:26 PM XXCoder: precision lathe wasnt really a thing till recently, with few exceptions
02:28 PM roycroft: back then people were workers, not whiners
02:29 PM XXCoder: I dont know. we only see works
02:29 PM bjorkint0sh: roycroft, haha
02:29 PM XXCoder: I wouldnt say one way or other
02:29 PM roycroft: no, really
02:29 PM bjorkint0sh: XXCoder, precision came with the screw.
02:29 PM Tom_L: tell me i can't back then and i did, tell them today and they believe it
02:29 PM roycroft: if you whined they would beat you to death
02:29 PM roycroft: so it was only the workers who survived
02:29 PM bjorkint0sh: roycroft, I think they made the whiners join the choir.
02:29 PM JT-Shop: and you only lived to be 40 anyway back then
02:29 PM bjorkint0sh: sing to the sun and whatnot.
02:30 PM bjorkint0sh: 'cause without singing its praises, the sun wouldn't rise.
02:30 PM roycroft: the ancient egyptians had a great apprenticeship program for immigrants
02:30 PM XXCoder: jt more or less. not sure if they included morality of babies and very young or not in life average
02:30 PM roycroft: similar to what we had in the american south in the 18th and 19th centuries
02:30 PM bjorkint0sh: roycroft, what? make them invent geometry and see if they get it?
02:31 PM bjorkint0sh: 'if you can invent what we teach our laborers, you can stay'.
02:35 PM bjorkint0sh: how the hell were the damned ancients so damned clever?
02:35 PM bjorkint0sh: is it because they didn't have tiktok?
02:36 PM roycroft: well, that plus they didn't have twitter or facebook
02:37 PM bjorkint0sh: the more I think about it, the more I wonder why no one ever combined Hero's steam engine with a lathe.
02:37 PM bjorkint0sh: it would have worked.
02:37 PM XXCoder: was engine known to them?
02:37 PM XXCoder: it existing in same era doesnt mean it was known
02:38 PM bjorkint0sh: 1 BC
02:38 PM XXCoder: and yeah sometimes people doesnt connect 2 different things together till someone finally thinks of it
02:39 PM bjorkint0sh: https://www.youtube.com/watch?v=3FyhNpHeHMM
02:53 PM XXCoder: yeah i know what it is
03:47 PM Tom_L: https://www.youtube.com/watch?v=o2rswxU99Dc
03:47 PM Tom_L: today
03:50 PM XXCoder: what happened?
03:50 PM Tom_L: i think 2 hit
03:50 PM Tom_L: on the runway
03:51 PM XXCoder: ouch. tower error?
03:51 PM roycroft: undetermined
03:51 PM roycroft: a coast guard plane collided with a commercial jet
03:51 PM XXCoder: hope they figure it and try avoid it happening again
03:51 PM roycroft: all the passengers on the commercial jet are ok
03:52 PM Tom_L: somebody in the tower is in deep shit
03:52 PM roycroft: five of the six people on the coast guard plane were killed - only the pilot survived
03:52 PM XXCoder: sucks :(
03:53 PM Unterhausen: There was an incident recently where the tower kept telling a landing plane to go around because they had released someone to taxi across the runway, but they ignored
03:54 PM Unterhausen: pilot said something about radio being inop, I think, but I'm not sure about the windshield
03:55 PM Unterhausen: would have been a major disaster if they taxiing plane hadn't hurried
04:03 PM Unterhausen: Rob Cosman says not to buy a standard angle block plane and then the one he shows has a very rusted blade
04:03 PM Unterhausen: 30 seconds to sharp, rob
04:04 PM Unterhausen: sorry, he says 32 seconds to sharp
04:08 PM roycroft: rob is turning into a hippie freak
04:16 PM JT-Shop: now if I can find the keyboard and mouse for the plasma cutter I can finish putting it back together
04:18 PM Unterhausen: it looks like he shaved and got a haircut maybe
04:18 PM roycroft: that must be very recent
04:18 PM Unterhausen: maybe I should get rid of my collection of #3 planes, he's right they are too small
04:18 PM Unterhausen: I like my #7
04:19 PM roycroft: i like mine too
04:19 PM roycroft: folks told me to get a #8, but i find the #7 works really well for jointing, and it a nice weight
04:19 PM roycroft: a #8 might be too big for me
04:20 PM Unterhausen: I want a 8 because I'm a hoarder, not because I would use it
04:20 PM JT-Shop: https://www.facebook.com/marketplace/item/1104660023870582/?ref=search&referral_code=null&referral_story_type=post&tracking=browse_serp%3A78a47fc2-749b-47b3-ac41-2640f88c542d
04:21 PM Unterhausen: I really would be better off not storing all my planes, have to think about getting rid of some
04:22 PM Unterhausen: Between the #6 and #7, I think I have 5 planes
04:22 PM * roycroft counts in his head
04:23 PM Unterhausen: I got some Millers falls that were ground on a surface planer
04:23 PM roycroft: i think i have 17, counting my router planes
04:23 PM roycroft: wait, that's not counting the wooden molding planes
04:23 PM roycroft: and i'm not going to try to guess how many of those i have - probably a dozen or so
04:23 PM Unterhausen: I don't have any idea of the total number
04:24 PM roycroft: i don't have many duplicates
04:24 PM Unterhausen: I bought a 55 so I didn't have to worry about molding planes
04:24 PM roycroft: i have a 45
04:24 PM Unterhausen: I have one of those too
04:24 PM Unterhausen: I always want to buy wooden ones, but I probably would never use them
04:25 PM Unterhausen: now resolving to sell planes instead of building more storage for them
04:27 PM JT-Shop: I was hoping that there was a 1/2 sheet of 11 gauge on the plasma table but it's a sheet of SS
04:37 PM Unterhausen: finding the material you need on the table would violate a natural law, like finding a scrap of wood the right size
04:42 PM vetsin: if i have a fpga (mesa board) does one need a base period set?
04:46 PM JT-Shop: no
04:47 PM vetsin: okay, cool, and since i use hostmot2 driver instead i still DO need to set my steplen/dirsetup times and such?
04:47 PM JT-Shop: yes, step and dir timing is specific to the step driver you're using
04:49 PM vetsin: did the wizard give me a SERVO_PERIOD for a reason then?
04:49 PM JT-Shop: now I just need to find the plasma table mouse
04:49 PM JT-Shop: wizard?
04:49 PM vetsin: the initial generator of my ini and hal
04:49 PM JT-Shop: yes
04:49 PM vetsin: https://github.com/vetsin/linuxcnc-pm30/blob/main/PM30.ini#L51
04:50 PM JT-Shop: hmm that's pncconf and I find it confusing
04:52 PM vetsin: yeah, i'm trying to read manuals and such to determine what my steplen/space/dir timing sshould be, and it's a load of fun when its all new to me
04:52 PM JT-Shop: your drive manual should have that
04:52 PM vetsin: it has *some* of them, i think. plus the language people use is different.
04:52 PM JT-Shop: mesact has a lot of preset timings for popular drives
04:53 PM vetsin: like i know my dir setup is 5us but hold time is what
04:53 PM vetsin: ill go look
05:11 PM JT-Shop: hmm found the mouse pad now where is the mouse
05:23 PM Tom_L: should be near the pad
05:24 PM Tom_L: i think i cured my following error. haven't had any more issues since i slowed the accel down
05:25 PM JT-Shop: there's one of those usb thingys plugged in so I assume it's wireless
05:25 PM Tom_L: sometimes i think we need cords on them so they don't run off
05:26 PM JT-Shop: I prefer corded mice
05:26 PM Tom_L: the one on this pc is but the rest are not
05:27 PM JT-Shop: I found one and it has the usb thing in it lol
05:29 PM Tom_L: is this a job for the grill ppl?
05:31 PM JT-Shop: yup
05:33 PM * JT-Shop calls it a night
05:51 PM Unterhausen: I'm left wondering what I did with my glasses
05:52 PM XXCoder: is it on top of your head>?
05:54 PM Unterhausen: good guess
05:54 PM Unterhausen: downstairs next to the cookbook, I think
09:48 PM solarwind: I wonder why smaller carbide insert sizes aren't more popular
09:49 PM solarwind: don't need an enormous CNMG1204 when _most_ of the material is wasted
09:49 PM solarwind: A tiny CCMT0602 seems to work just as well as CCMT09T3 or CCMT1204 and is half the price
09:50 PM Tom_L: are the 0602 the dimensions?
09:51 PM solarwind: Tom_L yes it's something called the ISO designation and uses metric units. Most of the world uses it. I think only one third world country are stuck on the old units.
09:51 PM Tom_L: it reminded me of smt resistor sizes
09:52 PM solarwind: lol just messing with ya but yes I really do hate imperial that much and will say it every single time
09:52 PM solarwind: same for surface mount components, I fucking hate imperial units
09:52 PM solarwind: thank dog aliexpress is like 99% metric
09:52 PM solarwind: if you search ANSI numbers, you will not see most of the results you want
09:53 PM Tom_L: these must be mostly for lathe
09:53 PM solarwind: yes, but milling inserts follow the same format
09:53 PM Tom_L: i know
09:54 PM solarwind: and there are face mills designed to use lathe inserts like WNMG and CNMG, but those are usually in carbide grades with higher hardness and lower toughness
09:54 PM solarwind: have to be a bit more careful or they will chip due to always being in an interrupted cut
09:55 PM Tom_L: i suppose you could take a wider cut with the larger ones
09:55 PM Tom_L: if you have the HP
09:56 PM solarwind: I never have a need to go even half as wide/deep as the cutting edge length of my smallest inserts
09:56 PM Tom_L: i watched a mazak taking ~.250" deep cut in steel dry throwing off white hot chips
09:56 PM solarwind: also I stick to **G*/**K*. I almost never buy **M* inserts anymore
09:56 PM Tom_L: probably a 4-5" cutter
09:56 PM solarwind: I can do that on my bridgeport just fine with a 100mm face mill
09:57 PM solarwind: especially with shallow approach angles for chip thinning
09:58 PM solarwind: on mild steel that is, I wouldn't try it on anything harder than that
09:59 PM solarwind: https://www.aliexpress.com/item/1005005367403022.html these cermet inserts are a dogsend
09:59 PM solarwind: I'm hitting all my boring operations to better than +/-5µm now
10:00 PM Tom_L: what do you make?
10:01 PM solarwind: parts for things I need, very random things. My friend ran into the side of my jeep somehow (gently) and broke the plastic step thing, so I need to make a replacement for that now
10:02 PM solarwind: also, lots of new parts for my R nineT motorcycle to replace the weathered plastic stuff
10:03 PM solarwind: like switch housings on the handlebars, all the things that the elements scuffed up over time
10:03 PM Tom_L: that's cool
10:04 PM solarwind: super random things, like a solid copper heat block for my 3D printer hotend
10:04 PM solarwind: as I was telling XXCoder, the ultimate high flow nozzle made from the base of a diamondback diamond tip nozzle
10:05 PM solarwind: machined the insides, put a larger bore in there, turned a pure copper insert to increase surface area in the nozzle
10:05 PM Tom_L: i don't make much for myself.. some but mostly for other ppl
10:05 PM Tom_L: mostly now i just like trying new things out
10:06 PM solarwind: a stand for my new stereo microscope that is fully controlled by motors for focus stacking at submicron increments
10:32 PM solarwind: that minimum depth of cut on the inserts is _critical_ for hitting final tolerances, and so the nose radius and chipbreaker geometry are critical. Deskar actually has a full PDF of all their geometries and most specs
10:33 PM solarwind: if you don't hit the minimum depth of cut, it'll increase the radial forces as the chip isn't thick enough to reach beyond the land and into the positive rake chipbreaker and totally messes up that final dimension
10:34 PM solarwind: if the chip is thick enough to fall into the chipbreaker groove, it pulls the part and tool together and almost eliminates any radial forces and chatter
10:39 PM solarwind: There is a lot more happening with respect to micro-chatter that nobody has any information about, but it's clearly happening becuase a vertical shear tool is able to make 10µm passes without chatter since it has practically no radial forces
10:40 PM solarwind: and the tool edge geometry has _everything_ to do with the surface finish and holding tolerances
10:42 PM solarwind: I find on large diameter stock, it's much less of an issue, but I almost never deal with something like a 100mm+ diameter bar. So same material, same cutting insert, same surface speeds and feeds, different surface finish depending entirely on workpiece diameter
