After Talking about this for a while I have begun to get this bad boy going. Last Saturday I received my glass hole saws that I bought from THIS company. After payment was received they took under a week to get here. And yes, they came from Hong Kong. The following pictures show the finished holes. I decided to cut back on the number of holes in the back do to bein skeered. I used a scrap piece of glass and cut a hole in it to use as a guide on the tank to keep the bits from jumping around. After scoring the hole on the tank, I then made a damn around the hole by siliconing a 2" bulhead nut to the tank. This allowed me to fill the damn with water and keep the bits wet as I drilled. It didnt take very long to drill the holes, maybe 20 minutes a piece. I kept the drill speed slow and used very little pressure. After cutting all the holes I then sanded each hole with 180 grit sandpaper. This rounded the edges and got rid of any sharp corners/edges.
