Nice first attempt we all have to get started someplace =). It looks like you are shooting for a planetary gearbox but its hard to tell based on the view. Planetary gearboxes are good for high reduction in tight spaces at the coast of efficiency. The ones we see in FRC most of the time have a locked Outer ring-gear, planet gears and sun gears. They receive an input from the motor that spins the sun gear. This rotation is spread though through the sun gear too the planet gears that revolve around it because the outer ring gear is locked achieving the reduction desired between those two interfaces. The rate at which the cluster of sun gears is rotating around you motors axis is your new rotation speed. These stages can be stacked by transferring the rotation rate of the planet gears down the line to another sun-gears input. With each additional stage come a reduction in efficiency.

A good place to start on planetary gear boxes would be to look at whats already offered. Vex robotics makes great planetary gearboxes that are stack-able. They have step files of the cad online that you should take a look at so you can better understand how they work. http://www.vexrobotics.com/vexpro/mo...planetary.html

That being said If I was starting out I think my first goal would be to make a spur gearbox. It is much more in line with what your team is capable of making. A lot of times planetary gearboxes will require special tooling to make. The plates for a spur gearbox could be done on one of CATs water-jets in less that 30 min. You can typically make them more efficient than the planetary ones but you do sacrifice a little space. If you need any help pm me and let me know.

Just food for thought

Edit- I understand now. I couldnt tell at first because everything was the same color.

How much does it weigh Including wire and motor controllers?
