When i track one down i will be sure to use all your advice. Thanks for all the replys! Do you think i could drill with a 1 1/2 inch bit and use a diamond coated dremel to make it fit a 1" bulkhead? Or is that to risky

I've used a variable speed drill with a round grinding stone to smooth out and open the hole a little after drilling. It will work but I had a couple of small slips and put several minor scratches on the glass around the hole. No biggy since it's a sump I was drilling, but you're better off being patient and getting the proper size bit.
