Second Wheel

Results from the second casting effort were good, probably better overall than the first. Surface finish was again excellent. At this stage I am convinced that the results from this design have been better due in part to the new cutters used when machining but mostly to the release agent used when casting. Neither of the mold-boxes had to be destroyed and both wheels slid relatively easily out during the de-molding process.

The upper photograph shows the various components used in the manufacture of one wheel. Clockwise from extreme left: Magnet, inner grip, hub, outer grip. Below is a close-up of the wheel showing the surface finish.
