It would be interesting to run an experiment. A generator is nice, but I 
suspect the investment in a machine for a single mirror may not be ideal 
(of course you will mak more mirrors ;-) ). Anthony Stillman's "can" 
generator sounds interesting, and I'd like to hear more about making 
one. I've tried making one with a diamond saw blade, but discovered you 
need *lots* of pressure on the blade to keep the diamonds cutting. I've 
tried a tile tool, but the tiles get thin rather quickly and then you 
have to make a new tool (yes, I was using the hardest tiles I could 
find). My favorite method is the pipe flange. If you put a "close 
nipple" and a "tee" on top you have a nice handle, and one tool lasts 
forever. Once the curve it roughed in, you pour a tile on plaster tool 
against the mirror, and it's close enough so the tiles stay nice and 
thick all the way to the end.
