Glass Work?

[jdwykrent]

Has anyone ever engraved glass with a diamond bit hat was not a drag bit with spring? I have seen the legacy video on youtube where he uses the 60 degree v. I picked up a 1/4" diamond bit that I was going to load in and run at 20,000 rpm with a cut depth of .005 and feed rate of 1.2 "per second.

Thoughts or bets on what will happen?

Jeff…
I think I saw the same or similar video a number of years ago… I had mixed results. I was using DS window glass and always seemed to break it before I finished a project… I decided it would require ¼” or thicker glass and never tried again…
