Just to let everyone know, I just posted the 2003 TechnoKat gearbox in the white papers section on this site and under the "Resources" section on the
TechnoKats site. This is the "2 speed, shift-on-the-fly gearbox" that worked well for us this year.
It is a significant improvement over our 2002 model. Most significant are the changes made to make it easier to fabricate (no EDM needed, etc.). The document includes an extensive writeup, assembly prints, BOM, and detail prints.
Download and enjoy. I will have hard copies of this at IRI (enough for 1 for each team).
If you use or improve upon this design, please let me know.
