Drilling a tank

[BCOrchidGuy]

Well it's been a busy couple of weeks. I've purchased the glass (1/4") for an external overflow and got my bulkheads and am close to finishing my stand.
For the overflow I tried the diamond bit dremel route but because of the thickness of the glass on my tank (5/8") it was painfully slow. My lovely, wonderful, thoughtful, brilliant ever so kind (not to mention beautiful) girlfriend bought me a new rotary tool kit for Xmas, one of the things it came with was a diamond cut off saw. I tried the cut off saw and the glass cutting went really quickly after that. Once I had the overflow cut I used the diamond grinding bit to smooth out the edges etc.
Now I'm in the process of siliconing it all up and I'll be drilling holes in the overflow for the bulkheads tomorrow.
I've built the sump from acrylic but am considering using a glass sump (15-27 gallon aquarium) and using the acrylic for a refugium that sits under the tank beside the sump. I need to figure out how to do it and allow room for a 5-10 gallon tank as my freshwater top off supply.
Once I figure out how to size pictures I'll post some pics of the system and my progress or lack there of.
