  Some time when you get a chance could you have your machinist
buddy give
  me a quote on making this plate?  It's aluminum and fairly
simple.  The
  center hole is really the only part I can't do myself.
  Thanks

  That taper on the center hole would be a real problem
  to do on an end mill with out a special tool I suspect.

  Since it is not critical I would cut it under-size and use
  a die grinder to taper it.


  BTW Roberto, this is Randy Lewis's turbo charged 12A one rotor.
  Handy in the Alps.

I would think he would cnc it with a ball end mill.  No problem
though I
think I'll try to make it myself.

Is it steel Randy?

Paul Lamar

If I had a choice I'd vote for a tapered end mill.  I didn't bother to draw
it and see what the taper was but I'm sure there is some options
there, otherwise as was noted a ball end mill would do it as well
[just take longer]

Fwiw
