Building the Bucky Wagon: Tires and Rims

Not everything about the Bucky Wagon could be faithfully brought over to the all-electric version. Most of the changes won’t be visible–the old motor, brakes and steering mechanisms had to go for obvious reasons, but their disappearance will not be immediately apparent to Badger fans watching the wagon glide by. But one necessary cosmetic change is being made to the wheels, specifically the wagon’s rims.

The original Bucky Wagon had split rims, the type that you might see on a tractor, with an outer rim supporting the tire and an inner rim that connects the axle and the tire. This makes tire changes possible without removing the entire wheel assembly, but the design of the rim places a tremendous amount of pressure on the bolts holding rims together. Changing split rims requires a level of experience that students working on the wagon might not have. And then there’s the small point that having students work with a rim nicknamed “the widow maker” probably wouldn’t be popular with parents and administrators.

Swapping the cumbersome old rims for new rims from Alcoa became a matter of necessity–they may not look like something that came off the assembly line in 1931, but the custom-made rims look pretty sharp just the same.
