Has anyone any experience with the book(let) advertised in back of Kitplanes:
"Prop Making for the amateur" "Best book on design and making wood props. "
by Eric Clutton ???
Any links I find to

Nigel Field's techniques are all dead ends.

Yes, Al's page is really good. The idea of a 3 bladed prop intimidated me until I came across this blade duplicator..it is a 1:1 pantograph router for doing props:

Cloning that device will be easy. What I like about it is all you need is a good master pattern and you can crank out a new prop. If you had a flexible composite blade mockup on a base with jack screws you could dial in whatever pitch you wanted and crank out 3 blades in less time than it would take to carve one of them.
I just want to know more about the glass or carbon spar  part of it, doing carbon leading edges, and what is the history of these kinds of blades as far as durability and safety.
Also, I have noticed prop tips with little hooked ends, whats the deal, who makes them and are they documented to be effective?
