I think I might give one of those silicone pot holders a try. Something about the mouse pad just doesn't agree with me
Last night I did some drilling on the overflow glass. I got all the way through on the R bulkhead but didn't go any further because I need someone to pour water for me. I started the middle hole as well. Hopefully I can start siliconing everything together this weekend.
For the external overflow I'm using 3/8" glass and for the internal weir I went with 1/4" smoked glass. I thought the smoked glass would be less see-through. Here's a comparison b/w the clear and smoked. I drew a line on the wood so you could see how transparent it is.
BTW, that triangle is for one side of the internal weir. I wanted it angled to eliminate any splashing of water going over the weir. What I'm going to do is put a bunch of black silicone on the inside of the weir and thin it out with a credit card to black-out the weir.
