Thanks. That gave me a few good chuckles. 
found this little trick on youtube for parting off.
wow, thx. Currently I can’t even part off w/ my mini-lathe (yeah, yeah, yeah - mostly due to lack of skill from the operator.) I’m going to try w/ this technique. I have always heard of running the lathe in reverse for some operations but it really helps to actually see it in a video.
Interesting video ltp. Moving from a HSS blade parting off tool to a carbide tip parting tool made a big difference to my lathe in its parting off abilities…
I’m not sure which lathes but some use a thread to screw the chuck backplate onto the spindle. Using the lathe in reverse could possibly unscrew the spindle/backplate.
My sieg is a one piece design (spindle/backplate) so no issues with either direction.
MRsDNF which carbide parting tool do you use? I saw one of the cheaper ones and the carbide tip kept falling out.
I have the 20mm tool linked here.

I would think any lathe with a reverse switch as standard equipment would be fine,
good point for older equipment though
My chuck is threaded to the spindle and never had a problem with it unscrewing. Saying that it never gets run real fast anyway.
does it have grub screws or any locking device ?
and it has reverse direction as standard ?
I was warned of this by several friends when I got my start. Not a ‘solution’ per se, but they all said that when running in reverse, keep the cross-slide and all hard parts clear with the tool and holder extended, so that if something goes wrong the tool/holder will swing clear or break instead of breaking the main parts of the machine. Made sense to me when explained thiscway but I never had that happen.

No. It does up against a shoulder. Whenever l remove the chuck it taks a hard knock on the chuck key to unscrew it.
I wouldn’t be running it backwards then mrs dnf
There is a lot of things mrsdnf should not be doing and a lot he should be doing but isn’t.
I wouldn’t be too worried about DNF, he can make his machines sing. 
I learned on the interweb that some machinists are fine with it but others are not. Hence when something goes wrong it’s a major issue causing fear in machinists everywhere 
I think it’s a bit like the exploding batteries to flashlights - it doesn’t happen often but everyone hears about it when it does happen.
is there enough wall thickness for a grub screw with a nylon slug under it so you don’t destroy the threads,
then again its been like that for 36 yrs.
Yep. I still remember picking it up in the blue ute. I’m sure you were there with me at the time. Need pictures.
I cut the corners off the end of the compound slide so I can swivel the QCTP without interference
Wow. That is one drastic mod. Your a braver guy than I. 
pp how do you find the quick change toolpost?
He probably looked for it. :person_facepalming:
