Learned something new today:
Early wheel hubs aren't the same as later hubs. The radius between the body and the flange is greater on a late hub. Early hubs have 1/4" radius and late hubs have 1/2" radius. (See photos. Yellow hub is late; dirty hub is early)
I discovered a crack in one of my hubs and bought another from Langs. Then friend John Semprez gave me one of his extras. But when I attempted to install one of the replacements, it wouldn't seat all the way down in the spokes.
That's when I discovered the difference in the hub design.
So, here is the dilemma:
1. When did the radius change so I know what to look for in another hub ?
2. Would it be safe to machine a smaller radius on a late hub ? Has anybody actually done this ? Is the part heat treated ?
3. I suppose I could increase the relief at the ends of the spokes. Any downside to doing that ?
4. Anybody out there have a small-radius rear hub in good condition that they would sell ?
I had discovered this as well
Was npt sure if early late or wheel maker
I'm sure the larger radius on the hub makes it stronger. I would opt to enlarge the chamfer on the spokes.
Cut that out!
