I would recommend using non o-ring chains if you were going to replicate this as the rubber o-rings didn't really like the heat of the welding!﻿ aming I think what John was asking, how is the drive going to be split, if it is only a single engine with no transmission then its the same as having a locked diff in a car and won't turn. He could possibly mount another two small centrifugal clutches on the rear sprocket with mountain bike disk brakes attached to each.  That would give him some slip in the final drive line and independent brake control of each track.  Good work EpicBuild.

Drill 10mm spaced holes around flat bar that has been wrapped over 5mm steel disk. Wrap solid cut piece of scrap tire around this flat bar and countersink holes for M6 bolts.
