I think I know what that wink is for. And likewise. Let's just say we both get influenced by the same guy whose intials are AB, if you know what I mean. (And travis, I hope you don't stick another stage on the end of last year's tranny for six speeds, that would be absolutely insane.)

Anyhow, a hex broach would be great, but the shaft this gear is on is .500" diameter up the line a bit, so machining down to a 3/8" hex on this round shaft wouldn't be too fun. Nice idea though.
