Step 3: The Mechanics

Picture of The Mechanics
I mounted a bolt thru the upper portion of the vertical support that would act as the axle for the wheel. I drilled a hole in the hub of the wheel and hammered a length of copper pipe into the hub and slipped a few plastic bushings over the bolt threads to make the wheel spin freely. I made a push rod out of a length of threaded rod attached to a small brick of ABS plastic I had in the shop. The mating post in the hub was made out of a few plastic spacers and washers and a screw into the wooden hub.
