Step 6Drilling the Cover Plates and Graph Paper Stack
I decided to drill the plates first. I clamped them together, measured where I wanted the three screw posts to be inserted, and placed a piece of wood underneath the bottom plate so the aluminum wouldn't "splinter" or warp when the drill bit cuts through.
After the plates were drilled, I used one as a template to drill the stack of graph paper. I placed the aluminum plate on top, marked the paper with a sharp point, placed scrap wood on top and bottom, and drilled.

How did you drill the holes (powerdrill/end mill/...)? I love the book, and would love to make one for myself!

I used a handheld drill with a simple drill bit. The aluminum drills easily... just go slow and wear eye protection as it slings off debris quite a bit.
