I figured out how to make a pretty good gear with my Dremel workstation using pre-cut discs and Popsicle sticks. This piece uses 2 gears at right angles which turns the propeller vertically while the chair on top spins horizontally.
This is about 11 inches high and about 7 inches wide at the base. I'm not selling this one online...I'm going to work on more pieces and have a local show somewhere.
