I've heard many people recommend sanding in reverse mode. Haven't done it yet. On both of my lathes, PM 3520B and Nova DVR, reverse is possible, but I would have to tighten a grub screw in order for the chuck to stay on. The one time I did that, the screw made a pretty big indentation and I'm hesitant to do that again.
What's the advantage of sanding in reverse?
Any way not to mess w/headstock spindle in doing so?
Thanks, Hilel.
