Gear Layout

Here is my current design for the gear layout, it's missing alot of supports and bushings at the moment but you'll get the idea. The motor connects to the blue gear, which meshes with the green gear equating to a 2:1 ratio. The green gear then spins the red worm gear which is meshing with the yellow gear with a ratio of 50:1. The yellow gear is also the output gear (shaft is underneath in this view), which will give you a 100:1 ratio * .44 oz/in = 44 oz/in of stall torque.

Just to give you some sense of scale, that blue gear is .25" in diameter.

Next step is to add the rest of the bushings/supports.
