Woodworking tools for prototyping.

I've been using an X-acto razor saw (1 mm cut width) and mitre box to work with balsa and dowling, and it's okay...but tedious.

I used a 4800 RPM mitre saw with an 1/8" cut width, which basically ate up 25% of the wood (when you're trying to make 1/4" x 1/4" squares...)

anyone know of any powered saws that would be good for making multiple wood bits at fairly precise dimensions / angles?

Making 200 wooden cubes is tough work!
