It would help us so much.

Short of a schematic, here's a quick description:

Gearing
A gear (G1) is mounted to the motor shaft. G1 then meshes with a second gear (G2). G2 is used to increase the speed. A third gear (G3) meshes with G2. G3 = G2, as it is used only used to provide opposing rotation.

Pulley system
A pulley is mounted to each of the shafts that support G2 and G3. Timing belts than drive pulleys attached to shafts which support the drums that shoot the balls. We decided to have a larger pulley diameters on the upper drum shaft to generate a backspin

I hope that helps. I can put together a schematic tomorrow in PPT, if you'd like. Let me know.
