Im looking for gears and such that will work well with a swerve drive. Dose any one have any suggestions on where to get gears for the motors that will turn the swivel moduels?

Hi,
Have you considered small pitch timing belts?
-
I have been looking at those and the more I look the more I think those are the way to go. But can I get ones only 4 1/2 inches long?

These (http://www.robotshop.com/120mm-40-tooth-tiiming-belt-1.html) are very close, but is the 4½" the distance between pulleys or the entire belt length (if cut and measured)?
You can calculate the exact size you need here (http://www.robotmarketplace.com/store_timingbelts.html) and find lots of different lengths here (http://www.robotmarketplace.com/products/timing_belts_and_pulleys.html) (main page here (http://www.robotmarketplace.com/marketplace_timing.html)).
Remember that you nee some way to tension the belt(s), either by a "blind" pulley, or by being able to adjust the position of one of the pulleys.

that would be from the pullys outer edges away from each other. yes im going to add a tensioner pully to each one but i will need four belts.

Hi,

Then you need belts that are more than 9" - when you have settled on the pulley sizes, use the calculator to get the exact length.
