   Paul,
   As I had cut the rotor in half, I could just punch them out. I was surprised
   how well seated they were, and the fact that they are 'one inside the
   other'
   type spring pins, would make them doubly difficult to remove from the
   outside.
   I suggested to Larry that a 2 piece rotor, friction welded together might
   make a good project. I mentioned this as the internals are simpler to do on
   a CNC looking from the centre - then finishing from the outside. To my mind
   it would be simpler than making patterns, casting and then machining. For
   production of numbers and economy of scale it might be a different matter.

I wonder if this NASA alloy would be dip brazeable. That would be the
hot ticket.CNC the rotor halves to perfection then dip braze. If it
doesn't work for that then I thought it would be a hot idea for a side
housing. machine two sides and dip braze. Det gun shoot and final grind.
Perfect parts and you could use 6000 series instead of shitty A356 and such.
