Hey Tony, I'm a glazier with my own business. Long way from Wollongong though. You need to ask for "Toughened" glass. All toughened glass comes standard with a "rough arris" edges. The last playfield glass I sold to a pinhead (nice old bloke about 60.....no shit) ....I think I charged him $40 cash.
Do you have a pilkington's glass (now called VIRIDIAN) in the gong?
If so we might be able to get an order placed through that branch for you.
Cheers
