This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

pretty easy to make them,made a few while back,using casting aluminium,yours i guess you will cut each teeth,casting is a lot better
I'm up for casting too , I just don't have a smelter.
i have one at work if you want to travel to fla lol

Josh, would brass maybe work better than AL? Just a thought.
Yea brass is better than aluminum
it is however a little harder to machine. But, if you are molding it, it should work fine. Just let Fred toss you up some gears. Get Extra so I one breaks a tooth.

gears are very very hard to make,if the right pitch or teeth dont match ,causes a lot of problems plus they need to be balance too
