Flat Car: Part 3 - Wheels, wheels, wheels
The wheels are going to be an important part to the flat car. Wheel V1 is made of two flat pieces, each with a chamfer, glued together. The chamfers make a nice spot for an O-ring to sit.
I used FR-1, typically used for making circuit boards, as the material for the wheel prototypes. I’m really happy with how the material worked out, easy to mill and very rigid. And it can even be tapped!
More to come.
