01:43 AM Deejay: moin
01:53 AM TurBoss: morning
01:56 AM XXCoder: yo
03:59 AM Tom_L: morning
04:00 AM XXCoder: yo
05:20 AM JT-Cave: morning
05:20 AM XXCoder: yo
08:01 AM JT-Cave: I have to make a quote for a machine I don't want to make so it's going to be high lol
08:33 AM Eric_: I don't know if that's a great idea because you'll regret it even if they pay you
08:39 AM Eric_ is now known as unterhausen
08:39 AM unterhausen: I made a mistake of not insisting I do the mechanical design on a project and the customer has a lot of bad ideas
08:39 AM unterhausen: If he had just let me design it out of 80/20, we would have been done a year ago, but he wants it to be made out of welded aluminum angle
09:27 AM JT-Shop: if your getting paid by the hour it doesn't matter lol
09:27 AM roycroft: holy moly
09:28 AM roycroft: it appears that i may receive the chisels that i ordered in the beginning of march today
09:28 AM roycroft: the ones that were to ship in 3 weeks
09:31 AM roycroft: i guess i'll see later on
09:31 AM roycroft: there is a delivery today from ohio, where they are located, and i don't have any other outstanding orders from there
09:31 AM roycroft: but the order is still marked "unfulfilled" on their website
09:33 AM roycroft: so on a more topic note, i'm thinking about using a rack and pinion system for the y axis on my router
09:33 AM roycroft: because of the length of the axis - i need 4' of working room
09:34 AM roycroft: would off-the-shelf racks such as one can get from mcmaster be ok for a router?
09:34 AM roycroft: the precision helical racks are really expensive
09:35 AM roycroft: again, wanting to hold 0.005"/0.100mm
10:28 AM unterhausen: I got some galvanized carriage head bolts and 2 out of 10 are impossible to thread a nut on
10:29 AM unterhausen: trying to remember if I have a 1/4 die
10:37 AM unterhausen: I guess I'll go to penn state surplus and see if any of the smaller computers are worth buying
10:52 AM unterhausen: I got a nema 34 motor mount from amazon. I was worried it would be too wimpy, but that's not true. Unfortunately it is not at a 90 degree angle
11:01 AM unterhausen: Maybe I should cut the braces and bend it straight
12:05 PM JT-Shop: I'd send it back
12:07 PM unterhausen: I officially feel like an old person, I had to get a student to help me open up the computer I bought to see if it has memory
12:07 PM unterhausen: they also had $5 paint, so my shop is going to look like a penn state classroom
12:11 PM JT-Shop: lol
12:18 PM unterhausen: The computer had memory and is much smaller than the mini tower I have now so I'm going to have more room in my mill cabinet
12:19 PM unterhausen: I think I'll hang it from the door of the cabinet and put stuff behind it
12:21 PM unterhausen: Specifically, my shop is going to look like room 303, because that's what it says on the can
12:26 PM roycroft: my fresh air respirator is out for delivery
12:27 PM roycroft: i'll be happy to get that - i've been wanting one for many years
12:51 PM unterhausen: which one did you get?
12:53 PM unterhausen: breathecool?
01:01 PM roycroft: yes, i got the breathecool
01:01 PM roycroft: it's the one i've been wanting for a long time
01:01 PM roycroft: i just got the half mask with it for now
01:01 PM roycroft: i can add a different mask/hood later if i want
01:01 PM roycroft: i might get a media blasting hood at some point
01:01 PM unterhausen: nice
01:02 PM roycroft: as i said, i've been meaning to get one for years
01:02 PM roycroft: the wood lathe that i just bought pushed me to get it now
01:05 PM roycroft: it will be useful for welding too - the half mask should fit under my welding hood
01:05 PM roycroft: i don't want to get a breathecool welding helmet - i really like my jackson, and want to keep using it
01:06 PM roycroft: i upgraded to a 50' hose, so there should never be a placement issue
03:20 PM unterhausen: is a uefi bios a problem? It seems like it has a way to go legacy, but I didn't see it
03:23 PM unterhausen: I see, they call it "secure boot"
03:23 PM unterhausen: everywhere else in the bios they call it uefi
04:16 PM XXCoder: roycroft: https://youtu.be/n2OStvRteRE might be interested on this dunno
04:21 PM XXCoder: he lives to live dangerously
04:21 PM XXCoder: *likes
04:26 PM Loetmichel: *PHEW* 'Nice' shift. 08:00 to 23:05... And no breaks. HUNGER! THIRST! Such happens when half the stuff to be on the exhibition isn't done by the time we have to build the booth. And tomorrow will be the same. (Tear the booth down. After the Exhibition closes at 18:30) ... Maaan i am getting to old for this shit!
04:27 PM XXCoder: ouch
05:06 PM roguish[m]: well. done for the day in the shop. time to go vote. to Newsom, or not to Newsom, that is the question......
05:12 PM CloudEvil: sigh
05:13 PM captain_morgan: vote no, the election is a sham and waste of money. We'll vote him out in an actual election
05:14 PM XXCoder: calfornia recall vote?
05:14 PM roguish[m]: the options are pretty poor................. so sad.
05:14 PM roguish[m]: XXCoder: yeah.
05:14 PM captain_morgan: because conservative crybabies know they can't win in a fair election
05:15 PM XXCoder: that guy is already "detecting fraud"
05:15 PM XXCoder: with no results yet
05:15 PM captain_morgan: 2 billion dollar election brought to you by 'fiscal conservatives'
05:15 PM roguish[m]: at least the state got rid of Kamala. .........shucked her off the DC
05:16 PM captain_morgan: dont get why conservative don't love her, she's a cop after all
05:16 PM roguish[m]: captain_morgan: there is not such thing as fiscal conservative any more, any party. they all spend like drunk sailor. just for different stuff.
05:17 PM roguish[m]: there is no longer any real connection between government revenues, and spending.
05:17 PM roguish[m]: all right. off to turn in the ballot. ttfn
05:41 PM unterhausen: I wish amazon would let you search by when they could deliver something
06:13 PM * JT-Shop starts cleaning out bay 3 in the garage for the Ridgeline...
06:13 PM Tom_L: oooo
06:13 PM Tom_L: finally ehh?
06:18 PM JT-Shop: well going to test drive a white one tomorrow, mine is scheduled to be built next month
06:19 PM JT-Shop: up to now they didn't have any Ridgelines much less the trim package I want
06:19 PM Tom_L: goin for white or gonna wait?
06:20 PM JT-Shop: just going to check out the features and stuff tomorrow... it's got to be Obsidian Blue Pearl!
06:21 PM JT-Shop: dinner time here
06:21 PM Tom_L: nice
06:40 PM Tom_L: the white is likely a pearl too, my kids went with that color
06:56 PM roycroft: my gazebo roof is almost done
06:56 PM roycroft: and i think i have enough materials to finish it
06:56 PM roycroft: i should have it done before the rain arrives
06:56 PM roycroft: there's other work to do on it, but i need to get the roof finished before it rains
06:56 PM roycroft: so yay
08:13 PM roycroft: my fresh air respirator has arrived, and i'm fairly pleased with it
08:13 PM roycroft: it was definitely a good investment
08:14 PM roycroft: but now i have to find a place to store the 50' hose where i can retrieve it instantly
08:14 PM roycroft: if i pack it away somewhere i'll be disinclined to use the device
08:15 PM roycroft: the hose made the air smell like china for a few minutes, but that went away, fortunately
08:15 PM XXCoder: smell like china thats weird way of putting it
08:15 PM XXCoder: you went to china in past?
08:15 PM roycroft: and i'm pretty sure the china smell came from the hose itself, as it smelled like that before i hooked it up
08:15 PM roycroft: i have not gone to china
08:15 PM roycroft: but we all know what china smells like from things we've purchased from china
08:16 PM XXCoder: not me
08:16 PM XXCoder: i cant smell lol
08:16 PM roycroft: except perhaps capthindsight[m], if all his chinese purchases were recent
08:17 PM roycroft: the pump is claimed to be 1.5hp, but that seemed a bit excessive, and fortunately it was an exaggeration
08:17 PM roycroft: i was afraid i'd have to lug a big, heavy pump around
08:18 PM roycroft: the recommended air movement is 6cfm, and i get that with the 50' hose with the motor turned almost all the way down
08:18 PM roycroft: so i know it can put out plenty of air
08:19 PM roycroft: the provided air flow meter peaks at 9cfm, and i hit that with the pot turned less than 1/4 of the way up
08:26 PM roycroft: the niosh spec is 4cfm for a tight-fitting mask and 6cfm for a hood
08:26 PM roycroft: i have a tight-fitting mask and was comfortable at 6cfm
08:26 PM XXCoder: roy saw that video?
08:26 PM roycroft: what video?
08:26 PM XXCoder: while he makes dangerous mistakes, the idea itself is interesting
08:26 PM XXCoder: https://youtu.be/n2OStvRteRE
08:26 PM roycroft: sorry, i don't know what you're talkinga bout
08:26 PM roycroft: ok, i'll take a look
08:27 PM roycroft: if it's long it will have to wait - the barbie is heating up and i have to tend to it shortly
08:28 PM roycroft: you are fortunate that you cannot hear
08:28 PM roycroft: that is just about the most annoying voice i've ever heard in my life
08:28 PM XXCoder: lol ok
08:28 PM XXCoder: you can "deafen" and turn on captions
08:28 PM roycroft: and what's up with centriFUgal
08:29 PM roycroft: it's cenTRIFugal
08:29 PM roycroft: and yeah, mute + cc is a big improvement
08:29 PM roycroft: anyway, it's too long to watch right now
08:30 PM roycroft: maybe after dinner
08:30 PM XXCoder: ok
08:30 PM roycroft: i already have a cyclone separator that works brilliantly
08:30 PM roycroft: so maybe not after dinner :)
08:30 PM roycroft: but i'll try
08:31 PM roycroft: my cyclone separator sits on top of a 55 gallon barrel
08:31 PM roycroft: i empty that barrel regularly
08:31 PM XXCoder: nice. that thing is interesting though, its nonrotatary seperator
08:31 PM roycroft: since i installed the cyclon separator i have not emptied the dust collector bag at all, and it's still empty
08:31 PM XXCoder: only thing that rotates is ducted fan
08:31 PM roycroft: the cyclone separator gets probably 98+% of the chips and dust
08:32 PM roycroft: this is a big deal because it takes me less than a minute to pull the separator off the barrel and change the bag
08:32 PM XXCoder: indeed
08:33 PM roycroft: it takes me at least a half hour to empty the dust collector bag, and another 45 minutes after that to clean up the mess i made emptying the bag
08:33 PM roycroft: i gave up precious real estate installing that cyclone separator, but it was absolutely worth it
08:34 PM * roycroft tends to the barbie
08:35 PM XXCoder: ya if I build a shop, id build one too
08:35 PM XXCoder: good way to get rid of wood dust
09:07 PM roycroft: norm mcdonald died
09:07 PM roycroft: he was younger than me
09:07 PM roycroft: he'd been battling cancer for some years
09:18 PM norias: hi Centurion_Dan
09:19 PM Centurion_Dan: hi norias
09:19 PM norias: how are you?
11:06 PM fdarling: I am interested in learning more about how LinuxCNC's PREEMPT_RT "main loop" works. I have made a program which does a 1kHz loop using clock_nanosleep, but the jitter is a lot higher than LinuxCNC's. I am curious if there any special techniques being used. Any recommendations on who I should speak with?
