Boring a super smooth surface
Hi all,
Is there a way I can get a mirror like finish on a turned piece of metal? I know I can use 1000 grit and finer on a piece as it is chucked and turning in a lather, but how about the bored hole? How would I get a, say, 1/4" or 3/8" internal surface glass smooth? I am thinking of some sort of expanding reamer that I could put a 1000 grit wet/dry sheet around and insert it in the hole as it is turning...seems like I would just bunch up the paper though ;-) Anyone ever have to get something "barring" smooth internally....what did ya use? Thanks again gang....as always, any help is greatly appreciated John |
