I can test one, but prefer not to penetrate any bearing surface.
Pick another spot, and I will do it, unless someone has the answer.

Archie, what do you charge to do the test?
Royce

Rockwell hardness test for rotary aviators,= $0.00

Archie

What a deal.
Give me your address and we will send you a shaft to practice on.
Since it will be cut down anyway you can test the front main journal, and the
front rotor bearing journal.  We use the rear rotor for the single rotor.
