Re: pic: Vex Face Bearing Gusset Gearbox

Interesting idea. Have you done any price comparisons between using your method and using clamping gearboxes*?

*See the "gearing options" portion at the bottom of the page.

All the machining required on the versa frame for this can be done with a drill press or hand drill and a dremel. You can match drill all the gusset holes. Any slotting required for clearance for the first reduction gear can be done with a dremel, cutting wheel, and some patience. All the piloting is handled by the gussets and bearings, so no precision machining is required.

A total of 84 teeth (20DP) is the "right" C2C distance for the 2.103" spacing used by Vex for the gussets.
