Thanks a lot, Rosco. I think I'm going to go with Stefano Prosseda's
variation, which you also mention on your webpage
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=9341
I clearly didn't quite understand the concept and now see how my design had
way too many gears only to accomplish something totally unnecessary: feeding
input force to both axles of the diffrentials, instead of one axle and the
diff body and using the other axle for the outputs.
