Re: Drivetrain Critiques

How large are the slots in the frame for the bearing blocks to slide in?

In 2011, we used 1/2" slots with 1/2" keyed axles and 1/2" OD spacers between the bearing blocks. Once everything was tensioned, we ran it in and the axles opened their own holes in the slots and everything was great.

We had no issues with 7075 aluminum axles, but did preventatively replace two because they keyways were opening (after two tournaments and significant pre-ship practice and development). We also ran 7075 axles this year, including many 1/2" dead axles and two 1/2" keyed primary drive axles (which drove the one live-axled wheel directly, and all of the others via chain).
