I did this as an experiment using the plastic gearboxes, shafts and axels suplied by first and purchased gears - there is a post somewhere of someone else who did this. The Chippawa moters fed into this I think it was a 30 fold reduction - so the speed was about 4fps. So comparable to a Fischer Price, but much more powerful, Unfortunately my entire robot platform was thrown out in a fit of spring cleaning - the gears cost about 300 bucks for two sets.
I had some pictures, put heck if I can find them.
SO worm gears will work, and you can make the transmissions with just a good drill press if you are carefull and precise.
I got the gears from "Boston Gear"
