I put together an Instructable on my 1lb bot Algos. It covers the initial build, some redesign, shaft hardening and titanium anodizing. The Instructable also includes .slddrw and .dxf's of all of the waterjet cut components used. Check it out and vote for it in the Digital Fabrication Contest if you like it.
