An easy way to test what ratio would be needed it to use the sprocket from a bike so all that would need to be done is move the chain to the next gear to change the ratio till a suitable one is found.

I have a pulley that I can change diameters on just by threading the outer flange further onto the hub flange. It goes from something like 2" to 4" or so.
