What also suprises me is how bad brand new props can be, despite

In my life I've purchased two brand new McCauley fixed pitch props.
Both were substantially out-of-balance as they came out of the box,
and both were fixed by a local prop shop. *I am amazed the prop shop

This flys in the face of the "FAA certified parts are perfect" theory.
One would think after spending several thousand dollars on a piece of
forged aluminum that might cost 200 bucks in raw materials that the
remaining costs are for the manufacturer to deliver a high quality
product. The fact that a local prop shop with crud tools can balance
it better then the manufatcturer is laughable......... JMHO..
