This is all hobby stuff on old worn out machines.

The wheels have a coating on them which I will hope will prevent corrosion, time will tell.

David, I had considered that. The idea was to see if these hubs could be made cheap enough to possibly manufacture the hubs to sell for other home builders to use with their wheel of choice. Opening the center of a rim could be done with a router, dremel or even a hand file if someone was determined enough.

There are several things I found that would make these easier and cheaper next time around.i have yet to weigh them.
