When I cut thicker glass, I tap the opposite side of the cut with the ball
end of the cutter to make small cracks just start. then turn it back over
laying on a good smooth surface to do the actual break. Line the cut line
with the edge of your table and make a quick snap break of the glass. I
also use a dremel motor tool to grind the sharp edges off.
another tip I do is use the small rasp with the motor tool to grind the
gluing
surface of the glass so the silicone will not slip. ( I had a tank bottom
slide down the sides of a 69 gallon, which made the bottom glass bow and
break on me).
Anyway, experiment. One work of caution. store your glass on its side and
not outside uncovered and the rain and sun will ruin it. I had several get
bad spots in them from etching. Fwiw . Jim

I've recently come into posession of 8 large sheets of 1/2" thick glass.
Has anyone had any experience with cutting this? What kind of tools will
I
need?
TIA


I would definately let the pros handle it.

Or just make a really HUGE cube shaped tank =)
