Not a project for the hobbyist!

I have a friend who designed and built custom propellers with CNC and composite materials. None of that in this video.

At the Evergreen Aviation Museum and I think at Wright Patterson AF Museum there were displays dedicated to the design and manufacture of wooden props. Quite a bit of the Wright's work went into that if I remember correctly. Once they understood how a wing worked they turned their attention to improving the props.

I worked at the 8 Foot Transonic Pressure Tunnel at NASA Langley. It also utilized blades made of spruce. Lord help everyone if a model failed and something went down the tunnel. The model shop was still running when I started my career but by the end it was another part of NASA contracted out. Big loss.
