Hopefully this year's drive train will be better.

I don't think that's what he came here for.
(kudos though, for 3 really good solutions).

Ah, I see what you mean. He wants a smaller sprocket on the gearbox itself, rather than changing other portions of the drivetrain. I assumed that he wanted to work around the problem of non-standard sprockets, rather than find or make another non-standard one.

This was implemented for a reason, which may not be obvious to everyone.

It is okay for you to hope FIRST will provide a solution with "standard parts".
A 1/2" Shaft with a 1/8" Keyway would be much easier, wouldn't it?

By the way, what was the reason? I can think of several, but I don't know which it was (e.g. "to make it challenging", "to make it metric", "because we had a pile of it lying around", etc.).
