Wow that looks impressive mate!I've made do with four clamps to hold the box square, and the power stapler is doing well.. it just can't drive the 38mm staples through the weathertex bottom board into the 'feet' underneath (even on the highest power setting and deepest depth of drive), so I've had to make do with 25mm staples but they seem to be fine.I've also figured out I can just rubber band the alligator clips of my embedder onto the terminals of the stapler battery for embedding the wire and it's quartered the time it takes to do that job so I'm pretty chuffed!
