I'm impressed with the Vex Pro 2 speed shifter and was already to buy when I noticed the output shaft uses hex rod.

The reason for wanting a round 1/2" shaft with a 1/8" key way is because this shaft will match up with a very wide range of sprockets and pulleys. In particular I would like to try out the belts in the kit of parts and substitute your nice 2 speed for the default single speed transmission.

Only question is how can I make this work when my team doesn't own or have access to a lathe or a broach/press?

Paul, is Vex willing to build a few special order shafts for smaller teams without machining resources?
