If you're going to use direct c-c, why bother using the WCP side bearing blocks? Teams have been very successful using flanged bearings directly in 0.125" and 0.100" wall tubes. The benefits of dropping the bearing blocks are lower weight, lower cost, slightly reduced tolerance-stackup and easier/more precise machining (circular holes vs rectangular cutouts).
Also, what size pulleys and wheels do you plan to use?

Size constraints in the gearbox allow for a 30T pulley running 2x 9mm HTD belts. Will be running 4" colsons.
