To answer ChaosMonkey's original question. There are several resorces out there. Machinery's Handbook is one. For questions on basic design of gear boxes it is very useful. Also about how to do tons of other things too. It ain't cheap so see if you can find a used one. They never go out of date, even though they publish a new edition every year. I used to borrow a friend's but he went to another company so I guess I'll have to go find one myself

I am looking forward to seeing Glenn's and Paul's designs. From the descriptions I have seen here, Paul's is very like something we were going to do this year until we went to three wheel drive. It would have been on my list of "must see" items if I had been in Florida. I also liked 190's CVT. I designed a version of that last summer that I dropped because it was too complicated. 190 showed me a simpler way. I had 5 "idler wheels" instead of 190's 2 because I underestimated the friction factor.
