As an aside, I drilled my sumps last night for 2" bulkheads. I got my 3" drill bit from glass-holes.com for $14. They also have a 'how-to' drill a glass hole video on their website.

Thx Jay,
I have the 1inch hole saw now. Tony was kind enough to lend it to me. Will be attempting the third tank tonight. First two tanks didnt work out so well so to speak, lol.

Both of them snapped cracks in the panel just as the drill bit got to the other side. I don't know if I screwed it up or if it's because the glass was pretty thin. It occurs to me I've never drilled anything thinner than 4.5mm before (this was 1/8" or about 3mm thick I think).
 I feel pretty bad about it. I've drilled easily 20-30 holes before and only had glass break on me in 2 or 3 cases, and usually there was a reason. One time it was because I lost my balance and fell forward onto my sump as I was drilling it. Another time was because I was drilling on the vertical into a running tank, probably the riskiest scenario of all.

Like I said yesturday, dont worry about it Tony. It is pretty thin glass and I appreciate you helping me out. I do have alot of scrap glass now thou if I ever need baffles or anything
 Hopefully the attempt tonight goes better as its the last tank I got. Ill let you know tomorrow. If it dont work I might just go order a tank predrilled.

oh wow, 1/8"? That would be tricky. I probably would have cracked my 1/4" if I didn't have a clutch on my drill. It snagged just as I was finishing up.
