stumbled across this on YouTube ,drilling light gauge metal
Nice trick ltp.
That’s neat, I usually clamp it between wood blocks and drill through everything. Hole saws tend to wobble and the wood stabilizes the cut before the metal is reached. My drill press won’t spin nearly that slowly.
I came across this. He does a pretty rough job but it seems to work.
thanks pp, surprised the sander didn’t burn out but.
I think i’m building one ,shooters use corn meal and other stuff on brass shells,
be worth a google, would have to be careful on aluminum
Why careful on aluminium?
I was thinking of how soft it is.
but after a bit of googling it seems to hold up well.
people use plastic triangles and walnut shells,
stainless steel shot and lots of different media.
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.
