Re: Beware - transmission output shaft is not 5/8"!
All I can say is WHY?!?

Why give teams a great transmission and make a drive system easier for teams to get up and running, but then make in necessary that teams turn down a shaft (a keyed shaft for that matter!) or ream out sprocketts simply to change the output sprocket?

WHY?!?

Does anyone know of a source of various 16 mm bore 35 pitch sprocketts with a standard keyway?

Perhaps I am a bit frustrated because a great deal of our work time goes into making non-standard parts work together. For teams with limited machining ability, this is a real issue. Yes, I know. It has always been an issue, but with the Kit Chassis, Kit Transmission, etc. FIRST has moved a great deal towards making things easier, but a 16 mm output shaft on the transmission seems to be like "Two steps forward, one step back".

(This whole thing was not an issue for us last year, because we made our own shafts that fit the Kit Transmission. I'm speaking for those teams who have limited machining opportunities - like us this year - we lost our shop!)
