Grinding glass with stone rotary bit?
massive88:
Turned out it was cut a tad small, and no grinding was necessary.
Thanks for the replies though!
RandyT:
For future reference, though, heat is glass's mortal enemy while machining. You can grind it all day long (yes, power tools are just fine) but you need to make sure you are flooding it with coolant (water, etc) while doing so.
My general thought on this (based on far too many years working with the stuff) is: If you see it glow, it's too late.
