Snips from Ron's post
>Glass will cut very easily with a continuos-rim diamond blade

Yes, I had a chance to use a continuos rim diamond band saw a couple of
times.  It was magical, like the proverbial butter and hot knife.  One
piece of glass was a crown, there were no problems.  The other was a flint,
it overheated and fractured twice.  Luckily on practice cuts.  I turned up
the coolant and turned down my impatience.  I've used circular blades to
split Pyrex blanks edge wise several time.  I've had a hard time lining up
the cut.


>...Another idea not previously mentioned is a diamond router bit.

I had no idea such tools existed.  Diamond dremel bits yea, but not router
bits.  Thanks Ron.

>...coated with some 30 grit diamond.

I would think so coarse a grit might cause a lot of chipping, but I'll try
it on your expert recommendation.


>...convex diamond wheel and
>VERY expensive.

Yea but they last forever, or until some dumb *$&# comes along and uses it
on cement like I told her not to.


>...a custom-made diamond sintered cup.

I took a length of cast off diamond sintered blade and hose clamped it to a
capped steel pipe.  Didn't even have to dumpster dive for this one.
