Mike,

When I set out to copy Ivan Teger's hubs this was one of the major (from a
cost standpoint) problems I had to solve. The best solution is a good
milling machine with less than .0005" runout. Then using a .013" carbide
end mill you can cut the slot for the top hat bend. You want the slot to be
snug around the top hat. I started with a .014" end mill but, when coupled
with my runout, my slots were slightly too large. For the actuator arms a
.015"-.017" end mill works well. The amount of change the hub can have can
be limited thickness of the actuator arm slots if the slots are too narrow.


Last but not least, by several end mills to start with. Ray told me this
and I learned the hard way after I dropped my first one.

Best,

Nick
