Thinking about the cutting scheme

Scaled some photos. Completely wrecked the Basic Stamp board in attempt to drill 3.5mm hole into the corners. 1.5mmm worked, but the larger bit cought the surrounding holes and tore the stuff apart. I'm thinking of redoing the board with an improved layout...

Realized that today I have "material-destructive hands", and decided to not cut out anything. Did calculations for the aft part of the underwater body, and got ready for cutting it out of the plywood.
