I haven't published the details of my prop construction, the details are
of my own design and still proprietary for now. But here is my method in
general: The blades are all carbon fiber with internal carbon fiber
spars and are layed up in molds. The blades are done first and all
blades are built at the same time because they tie into each other in
the center, so a mold has to be built for each blade in the prop. The
last step is to build a laminated hardwood hub around the blades.

Thanks for the info Perry,
Can you say what the final prop weights were?
Cheers
Cary

The 3 blade 72 dia 88" pitch prop Perry built for me weighs
17 lbs.
