I did some proportion work and decided I need 6” wheels. The wheels I found have barring that are made for a ½” axle. For the axle, I went to steel supplier and had them cut some 43” pieces for me.
I have the axle and the trucks. I needed to find a why to attach them together. My original thought was to use a bracket system. That would have worked fine but the difference in the length of the axle and the truck was causing a little flex. I decided to dado out a channel into two pieces of poplar, the distance between the wheels, and encase the axle. This solved the problem of the flexing and how to attach it. I screwed the first part of the axle housing to the MDF truck piece, put the axle in, and screwed the other axle housing piece onto the first.
