02:08 AM Joco[m]: need to make some T-nuts. To manual machine or CNC. hmmm
02:41 AM Joco[m]: i think I just need an excuse to play lol
05:20 AM JT-Cave: morning
06:16 AM hazzy-m: morning
09:32 AM Lcvette: morning!
09:33 AM Lcvette: Joco: if you cnc them you can thread mill them!
11:16 AM JT-Cave: Lcvette, do you use anything like this with your jack stand? https://www.amazon.com/JGR-Billet-Aluminum-Jacking-Corvette/dp/B07S7PSQMG
11:17 AM Lcvette: yes
11:17 AM Lcvette: i made some pucks for the C4
11:17 AM JT-Cave: is the C4 different?
11:18 AM Lcvette: so it isn't lifting on the plastic rocker panel
11:18 AM Lcvette: yes
11:18 AM JT-Cave: I used a block of wood the other day
11:18 AM Lcvette: has a reglangular pocket for lifting
11:18 AM Lcvette: that works too
11:19 AM JT-Cave: I was concerned about it falling off when I lowered the car on to the jack stands
11:20 AM Lcvette: does you jack have a removable platter?
11:20 AM JT-Cave: yes
11:20 AM Lcvette: and a hole underneath
11:20 AM JT-Cave: yes
11:20 AM Lcvette: you can turn a puck that fits that hole
11:20 AM Lcvette: and one that fits the hole under the rocker panel
11:20 AM Lcvette: then there is never concern of it slipping off
11:20 AM JT-Cave: I lifted the car by the aluminum cross member and a 2 x 12
11:21 AM JT-Cave: then put the jack stands under the tie down points
11:21 AM JT-Cave: oh well lunch minute is over with back to work

12:25 PM JackDavies[m]: Hey guys! I just finished my work probe, I need to set an XY offset as it’s not mounted in the spindle and I remember reading about that a while ago. Any ideas on how to do that? Cheers 😎
01:25 PM hazzy-m: JackDavies: you can set the X and Y offsets in the tool table
01:26 PM hazzy-m: you make have to enter them manually if the TT in PB does not show them
02:34 PM Joco[m]: <Lcvette "Joco: if you cnc them you can th"> 😇👍👍
03:22 PM roguish[m]: Lcvette: got a link of something to the new installer?
08:24 PM Lcvette: roguish: i have not even tested the new installer yet
08:24 PM Lcvette: Turboss Haas to educate me on it

08:28 PM Lcvette: Hi Annette
08:28 PM Lcvette: o/
08:28 PM Lcvette: Welcome!
08:55 PM hazzy-m: Lcvette: nice!!
08:55 PM hazzy-m: first part?
09:09 PM Joco[m]: Lcvette: first movements on the lathe??
09:09 PM Lcvette: Still just doing mdi stuff
09:10 PM Lcvette: Everything is pretty simple and I'm still learning to trust it's tolerance capabilities
09:10 PM Lcvette: I trammed the head today...
09:11 PM Lcvette: Worked on our for about 2 hours
09:11 PM Lcvette: I finally settled on 0.001" over 12"
09:11 PM Lcvette: Could get rid of the last little bit
09:12 PM Lcvette: May be the bed or i dunno but it's add good as i could get it
09:13 PM Joco[m]: that is 0.001 parallel turn over 12"?
09:13 PM Lcvette: Needed top make some finite adjusters
09:13 PM Lcvette: Yeah
09:13 PM Joco[m]: that's prety good
09:13 PM Lcvette: Once 12" it had a 0.001" diameter change end to end

09:15 PM Lcvette: My test piece
09:15 PM Lcvette: And verified with an mt4 ground tram bar
09:16 PM Lcvette: Maybe with some fine thread adjuster yang's i could get that last thousandth out
09:16 PM hazzy-m: I'd say that's very decent for an HF lathe ...
09:16 PM hazzy-m: did you regrind the ways?
09:16 PM Lcvette: No
09:17 PM Lcvette: Only upgrade to the machine besides cnc conversion is nachi tapered roller bearings
09:18 PM Lcvette: Runout on it is less than 0.00005"
09:18 PM Lcvette: The spindle was very will ground
09:20 PM Joco[m]: so the standard spec's from memory is a center lathe should be within 0.02mm over 300mm. Tool room lathe is supposed to be 0.01mm over 300mm
09:21 PM Joco[m]: i'm trying to find the testing manual to doubel check that
09:22 PM Lcvette: I'm not close top that
09:22 PM Lcvette: Lol
09:24 PM Joco[m]: yeah but if the bulk of what you are doing is within 150mm of the chuck you will be pretty tight
09:24 PM Lcvette: Yeah
09:25 PM Joco[m]: I spent HOURS on my lathe. got to within 0.001mm over 200mm
09:25 PM Lcvette: I just would like it to be half or less of what is it
09:25 PM Joco[m]: but the time I invested to get to that was silly and it will go out of that spec between winter and summer just from the heat changes
09:26 PM Joco[m]: so it lookes good on paper and is just complete waste of time. lol
09:29 PM Joco[m]: Lcvette: were you adjusting the ways twist, aligning the headstock, or both?
09:30 PM Lcvette: Aligning head stock
09:31 PM Lcvette: It doesn't have an alignment rail
09:34 PM Joco[m]: alignment rail - what's that?
09:40 PM Lcvette: The V most lathes have on the slides
09:40 PM Lcvette: It's dovetails and the head sock is just flat at the mating surface
09:48 PM Joco[m]: ah ok
