Bench Top Lathes???

I was thinking a very light turn or even just something to hold them while applying the emory cloth evenly might do it.

I've been thinking of how to hold and spin with a floor model drill press but haven't come up with anything,
Get an old electric drill and fashion a way to mount it to the table, spinning a large object in a drill press will turn into a projectile. Been there, told him not to, and he did it anyway. I was right! With support on the loose end its in complete control.
