September 30: Engineering problem 1 (band slippage) I think is solved. I added a curved metal strip across all the bands.
I’m in the process of solving engineering problem 2 (wheel fragility and mount) – I’m making slicks for the tires. I spent a few hours today cutting out more wheel discs and gluing them. I think I actually made the slicks too thick, but I can always cut them down making them thinner. I still have yet so solve how I’m going to attach them to the axles, but I think this is a start in the right direction.
BTW, I had to get another gallon of Elmers glue. Also I’ve just about burned through all my cardboard making the wheel discs. Now I have a nice big pile of scrap.
