This seems a bit clumsy to try putting the jaw on while holding the T-nut in the slot. I've always found it easiest to loosely assemble the nuts on the jaws and slide them in from the top. Then I'll use a tool (usually a Boring bar) and call it to the diameter of my part. Then I move the jaws in further until I can see they'll clean up and leave a nice shoulder to stop against if needed (also leaving a little more for when clamped mid stroke). Once I have one jaw set I jog the X-axis to a visual reference spot on the jaw (usually the apex of the existing diameter if re-boring a used set, or to one of the bolt holes). I'll then rotate to each jaw position and slide them in aligning the reference point (bolt hole) to the tip of the tool to ensure the jaws are all on the same notch. Nothing is worse then trying to get one last notch out of a set and one of the jaws was off by one and can't make it. Also torque specs for the M12 bolts on most chucks is 68Nm per Haas Guidelines.

yeah i really said "hhhwhat in de fuhhhh?!?!..." when i saw that

[@andrewh2341]

Didn’t really learn anything from this and most of the video was of the poor guys back covering up what he was doing. Maybe try a GoPro or something mounted inside so we can see what he’s doing in the future.

[@ArmyMatt79]

Great Video!!! I'm a Mill guy, and only go on the Lathe every so often. I want to master the Lathe, like l am on the Mill. My Boss is AMAZING on the Lathe!!!😃

[@vitorbruno8105]

Where can i find this fixture for fixing the soft jaws ?

[@arsehole420]

what is the clamping psi and the max g50 rpm to use those at???

[@I.Odnamra]

About 110 psi and no more than 500 rpm. Could be less on the rpm but stay under 500.

[@bigbattenberg]

I'll be damned if I watch a guy looking like an outlaw machining jaws. A reminder of how stupid the times are I guess. Next!

[@arcigeedlaba4433]

Not a good explanation. Even the video. Anyway it makes sense..

[@VictorHernandez-nt3tw]

Keep these videos up! Thank you!

[@vee9005]

Got absolutely nothing from this ..😢 😔 sorry had to say it....

[@Jonesie170]

yeah would have been cool to actually see the machining at least
