Re: Drilling hole in tempered glass?

[PApple16@aol.com]

this may sound crazy, but it works. make a circle of wax around the area you 
want to drill a hole. using a flat ended piece of drill stock in a slow speed 
drill, use ordinary valve lapping compound (silicon  carbite)(put a fair 
amount in the wax ring) slowly lift then press down against the glass working 
the 
valve compound between the glass and rod. it takes ahwile, but works every 
time. just be light handed ,and patient
