PVC pipe is easy to obtain and it’s inexpensive. So, I’m building the prototype suspension parts with 1/2″ PVC pipe and various fittings.
I drilled holes in the pipe at the pivot points and inserted some 1/2″ x 1/4″ nylon bushings along with some 14″ x 20T bolts.
Each side took about 20″ of 1/2″ PVC, 4 - 90 degree elbows, 3 - 45 degree elbows, 2 nylon bushings, 7 washers, 2 bolts and 2 nuts.
Next I’ll add the arms that extend down to the axles and the wheels. Then, the whole assembly gets mounted to the main chassis.
