Since the drivers of the tank are kids, I spent some extra time making impact resistant firewall and chain guard. The engine firewall is 1/4″ uhmw with wood supports.
The chain runs right next to the driver so I made an enclosure of uhmw and plexiglass. I used plexi so I can still see the chain to watch alignment, tension, etc.
I reused the levers from the old electric control box.
And now I’m working on a tailpipe to keep exhaust out of the drivers area, gonna fit an o-ring and flange to bolt it on.
