Picture of The shim

The rim was originally designed to be mounted on a tapered axle. Eight oak shims were cut to fill the gap between the straight automotive exhaust tube and the tapered rim. Friction from these shims being hammered in is all that secures the wheel to the tube. That way if I ever decide to display the wheel in a different manner, I will not have damaged it.
