You can’t see all the good stuff. (what would be the fun in that?) You can, however see that we’re working on a very rugged 6 wheel drive system for this year. We’re about 2-3 hours and some wheels from a working drivetrain. Then we just have to build the mechanism we’ll score with.

Lookin good!
how do you tension the wheels?

the chain tensioners are going to be UHMW plastic. (I love the stuff[think cutting board stuff, but stronger])

Also, the gearbox drives the center wheel. The front and rear wheel are slave-driven off the center wheel.
