Drill press. Hole saw. VERY gentle feed pressure, very slow
RPM. That's what comes to my mind.

Thank you all for fine suggestions. The glasses are $1 type
until I
find the best way to put a 3/4" hole in center. Please don't
ask me
what for...I will have to kill you but will reveal the
reason
when successful.
I'm inclined to try the heated points first then enlarge
with tubing
until the right size is met.\
This means a lot to me and I am grateful for you input. You
all may be
participating in a major discovery.
