Where to get 20 tooth sprockets for plaction wheels

We are at 10.05 fps, and want to go around 12 fps.

And you can't find a larger sprocket for the transmission?

We're using CIMple boxes, so that's 12 tooth pinion gears on CIMs going to a 56 tooth output gear which runs a 15 tooth double sprocket, going to "x" tooth sprockets on the wheels, where "x" currently is 22 or 24.

We can't change the gearbox itself, so we either need a larger double sprocket to mount on the CIMple box output shaft, or smaller sprockets to go on the 4" AM plaction wheels.

And you're stuck on using 4" wheels?

Yes.

or you could find 2 half inch bore sprockets with a key way (you could add that if you really had to) thin enough so that 2 would fit on the output shaft back to back.

Hmm. That... Could work.

look into using the AM sprocket hub that is designed to fit on a 1/2" shaft. Although you'd jump up to a 22 tooth sprocket

Thanks!
