John Strong's books on laboratory and optical techniques,
as well as in one of the ATM's describe two methods.
The easiest is to cut a square out of the glass (by scoring
with a glass cutter, and breaking along the line), and then
breaking the corners off to make an octagon, and then either
hold the octagon in your hands and use a revolving iron disk
charged with #60 Carborundum to grind the octagon round, or
use pitch to secure the glass to a steel disk on the end of a
shaft, which you revolve by chucking in a lathe, and rubbing the
edge of the glass with a springy piece of steel mounted on the
tool post holder, and charged with #60 Carbo.
This might be easier to do by going to a professional window glass
shop. They usually have a Carborundum belt sander that is water-
cooled, so it removes glass at a great rate.
Have to leave now, if you want to hear other method, let me know.
