Acipenser 2012 nano contest entry.

[Acipenser]

So after driving around and not being able to find the 1 1/16 bit and not wanting to wait any further I went to princess auto and picked up the 1 1/4 inch diamond hole saw and mandrel total price was about $11 extra hole saws will be about $8 the first hole I burned thru the glass pretty fast second and third holes were a little slower. The 1 1/4 hole is quite a bit bigger but the bulk heads can easily be positioned. I also started to mock up the corner over flow with card board so I can get the glass cut.
