[ATM] trepanning with an angle grinder?

[Dave Smith <smithersscope@yahoo.com>]

Hey Everybody,
Some time back I ran across a webpage that documented
the use of an angle grinder (I think) to trepan glass.
If I'm not mistaken the author also used the grinder
to pre-generate the blanks using computer control. The
image I recall seeing was a disk or angle grinder
mounted vertically (using a fabricated plywood
mount/housing) above the grinding table and was
lowered so as to place the grinding disk tangential to
the desired cut diameter.

For the life of me I can't find the page by Google
and, although I bookmarked it at the time, cannot find
the link.

Can anyone rescue my lost brain cell?
Thanks!
Dave
