[Healeys] Wheels

[Bob Spidell]

The tops of the hub splines should be flat, not rounded.  From the
side, the profile of the spline is an isosceles trapezoid.

The hubs are (probably) cut round on a lathe, then the splines are
cut perpendicular.  If you look at new hub splines with a magnifying 
glass, you can see the machine marks from the lathe on the top.

If the splines are "sharp;" i.e. there is no flat surface on the top,
the hub is shot (wheel or adapter).  Unless the (adapter) hubs 
are almost new, it's a good idea to replace the hubs when you 
get new wheels. If the hub splines are worn, this allows the 
wheel to "ratchet,"  causing premature wear and (potentially) much 
grief.

Wire wheels are a PITA, but, boy, do they look good ;)
