Thanks Rick, I used to be afraid of the lathe. But once I got used to having a 3' diameter of wood spinning at near 1000 rpm, and a couple of pieces blowup, it's now my favorite tool. I can see when I get back to improving my website I may need to make a few videos.

Yes I'm turning freehand, largest diameter I've turned was 120" diam cylinder 18" long. that was +/- 1/16" in diam. I've also turned a 36" aluminum pipe flange pattern, by hand, that need to be within 1/32". Can I get closer with a compound? That would depend on the machine, probably not with the machines we had. For smaller diameters there is a technique to it that involves a rule, outside calipers, straight edge and a lathe parting tool. we then use a pi tape to verify the diameter, it can read to the .001".
