Demonstration of my first pin gear ring gear using Matthias Wandel's Gear Template Generator Program available at http://woodgears.ca I was really impressed by how fast and how smoothly it ran. While filming this, I didn't know if I'd end up with an errant ninja-frisbee low orbit (or twice around the shop) projectile. HA!
