very nice! i'm impressed you were able to do that with only VEX parts. what ratio's are you getting from it?

Re: pic: Vex 2-speed gearbox
 

Currently, it only switches between a 5 to 3 ratio and a 3 to 5 ratio, but you could easily change it any ratio you want. There are also 2 sprokets at the end if you wanted to speed up or slow down the whole assembly.

Thanks for your kind words!

Very well done, I saw the same thread, it was quite interesting. I would try this my self, but with the ongoing FVC competition parts are limited, but we got a whole robot done today. I hope your design turns out well, it seems it could be braced alittle more, but other than that great job :D
