How do you get the cutoff tool to work so well? When I try to use it, I usually end up throwing the part, and blowing the fuse in the mini lathe.

@wally53511 I have just a little steeper angle sharpened on these tools. They generally only need to cut brass and plastic and occasional aluminum, so that works well. I also keep them very sharp. Other than that, nothing special.

Thanks.

nice job, please can you tell my what motors did you use, I mean what torque?

These were 270 oz nema 23's. Thanks.

mini lathes don't come stock with QCTPs. You have to buy those separate.

(airgun parts anyone?) looks like a really capable setup ! -and- polish is better done with chromium oxide (the green stuff) on a hard cotton buff - sandpaper takes away too much material with one careless move. You set it up to a ten thou, why take twice that with sandpaper? Ok for pens, but not for (ok just me) gunsmithing...

I would rather hear the noise of the lathe :)

turrning with a parting tool is fun did that for the first while before i was able to afford tooling worked pretty good ,

Thanks for the help.

The outside did not need turning and therefore making it shiney first cuts off a finished product. This brass rod is pretty dull to start with.

It can tarnish later for all I care, but I want it looking good to ship.

It's really not that visible in the finished product anyway.

If you have ever turned things on a wood lathe, this is where I learned to polish using varied grits of sandpaper. Think turned pens.
