This is a shot I took of the cutaway at the McCauley display.
Interesting features are the phenolic connecting rods used to
turn the translation of the oil piston into turning the blades. Also
the fact that the balls are rather large, and in pure thrust bearing
configuration. Blade retention is provided by a split ring on the
inserted blade shank coupling to the inner bearing race of the
thrust bearing confuguration. Somewhat like an oversized
valve keeper. Also note the the rather significant
bulk and robustness of the assembly as compared to other
after market configurations.  - Vance

It's them heavy aluminum blades.
