Thanks again Quagmire
And Jody, half as good I could handle... but I'm just afraid that your tank will look twice as good

I've recieved a couple private messages from people asking how I cut the glass for my overflow. I actually have to give credit for the idea to a user on reefcentral named Tunjee who had a thread discussing using a dremmle to cut an overflow.
He cut a bunch of slots in the back of his 20H and the job took him about 8 hours. He used diamond coated dremel bit #7103 to start each hole and then #7134 to grind it out. I am not such a patient man so I cut a single slot 7 inches long and then used a piece of black eggcrate to stop critters from washing over. Because I only had to start one hole I just used bit #7103 to do everything (still have it if anyone wants). When I did it, I laid the tank on its side on my front porch and ran a trickle from the garden hose over the glass being cut to keep it cool. I set the dremmle on high speed and cut through the glass with a sawing motion like I was using a file. It only took about 20 mins and I had no concerns about cracking, it cut so well. I used the same method to cut three 1" bulkheads without any problems. HTH.
