Re: The perfect 2 speed Transmission..... features...
okay.... i know this topic is shifting (due to me) from general to focused on our private transmission issues.... so let me bring another two things up:
* chain... how should it optimally be distributed for a 6 wheel system... (center and front an back wheels) we think it should go down from 1 sprocket to the center wheel (with sprocket reduction, then 1:1 to both front and back via sprockets... so basically 3 loops of chain...

* Encoders : what to use for appx 1200 RPM and a 6" wheel.... optical or mechanical.... i think i am leaning towards optical as it is easier to integrate into the tranny... unless it has horrible resolution... i don't really care about readings per revolution as long as its more than like 4-5 (w/ a 6" wheel it barely matters so much)

* Bearings.... do you really even need any ball bearings... esp if your trying to save SPACE...(i.e milling dog mates into gears theres no room for a 7/8" bearing!) i think brass ones are okay... they're rated for 2000 rpm... anyone else used these how do they do at high rpm... do they make bushing type bearings (not ball) for high speeds like 3000 rpm etc....
