We used the Chias geared down 3.5:1 to match the drill gearbox in high speed. We then had a 4.8:1 reduction to the 8.5 inch wheels. We used all sprockets and chains. This setup work astonishingly well and we never had problems with the drill motors, gearboxes, mounts, or couplers. The only thing we had a problem with was getting our shafts aligned correctly and keeping proper chain tension. These two things caused us a lot of binding and high current draw but we didn't trip the 40 amp breakers. Our battery just died fast.

Our drivetrain fabrication required the use of a mill and a lathe to make shafts and pillow blocks and to bore holes for bearings.
