by gears properly spaced do you mean simply add the pitch radii and for the shafts secured you mean like collars and whatnot.... or is it something else?

if we build this thing it will be probably the hardest one to build so far.... esp considering the 1/4 " shafts, tiny parts, and the tight squeeze, our first 2 spd tranny was like 12X4X6 inches!!!! this one is like 4X4X2! (actually smaller if you don't count the extra empty plate for mounting) i mean for this thing i will have to countersink holes etc... so that screws don't hit gears etc etc... while on the last one we'd just move the gear forward some ... they were 20 pitch gears too! and like 1/2" face width ...
