RE: Search for Custom Carbon fiber blade maker
You stated that this is a prop assembly, so does that mean you are machining an aluminum clamshell prop hub and there would be 4 blades with molded bosses at the root ends of each blade allowing you to dial in the pitch? The prop on the airplane in my avatar was 64" dia. 3 bladed carbon fiber adjustable pitch prop with an aluminum clamshell hub, and I also built a few sets of this same design but smaller dia. for the Southwest Research Institute about 9 years ago. Anyway it is a good way to go because all you need is a one blade indexed toolset and they are all the same after that. Best of luck to you...
