Re: [ATM] cutting a big piece of plate glass into mirror or tool

This should have gone to the list first time round, sorry Roman.

There is a way of making it round by supporting the mirror on edge on 3
wheels.
One of the wheels being a grinding wheel.
I cant remember if the grinding wheel goes between or at either end of
the two freewheeling wheels.
Cant find a source either just now but it has been discussed on one of
these lists by I believe Richard Schwartz.
