LF: 1-3/4" Glass hole saw (ScubaSteve trade)

[ScubaSteve]

Ok, So I've been trying for about 3 weeks now to finish this tank build but the woman who runs Niki Glass has ****** up my order 4 times now and is slowing me down.

The issue I am facing at the moment is that she drilled the holes on my return at 1-1/2", not 1-3/4". This means I'll have to do 3/4" drains instead of the 1" I planned. I can't go back to this women again to fix her screw ups... I can't... I just can't. Everytime I talk to her it gets worse....

So I'm wondering if someone in the Vancouver area has a 1-3/4" glass hole saw that I can borrow for an afternoon to widen my holes? Or better yet, help me? I'll trade you a 6-pack of your favourite beer for your troubles.

PS. Do you think it's possible to redrill around an already cut hole?
