Anybody remember what's the big thing a DUMP truck really needs to be able to do?
Well then we better do something about that!
These bomb-bay doors have a 'wired' rolled edge, so i poked some brass rod stock into them. Brass rods have a groove to retain a splitring that attaches to chain. Notched out bottom of the forward C-channel for clearance to fully close. Attached some split-rings and chain to doors. Made a servo holder and stuck that in the 'bridge' going to hitch.another splitring holds chain to servo
I dunno, maybe that's enough servo to hold the doors?
