Re: Drivetrains beyond the KOP
I'm glad you have taken interest in going beyond the kit. Next year's rules have not yet been released, but in the recent past, there has never been a requirement to use the kit-supplied gearboxes and it is not likely there will be.

AndyMark makes a single speed gearbox quite similar to the kit-provided gearbox but it has slightly different dimensions and mounting I believe. Their shifter gearbox is a whole different beast.

Some good sites for gears and other components (bearings, etc) in no particular order are:
www.bostongear.com
www.wm-berg.com
www.mcmaster.com
www.smallparts.com
www.motionindustries.com
www.sdp-si.com

A common size of gear used in custom FRC gearboxes is 20 pitch, 14.5 degree pressure angle, 3/8" face width.

Here's our 2005 transmission and here's our 2006 transmission.

If you have some more specific questions I'd be happy to provide some more specific answers.
