I currently have a prop to use for my 1/2 VW. However…. I’m debating about also carving a few as backup (at least one).  I also just have this strange urge to carve some small ones of my own design and using on a spare 3.5 hp Briggs & Stratton tiller engine. Put it on a test stand to play, or maybe something else?

Here is a GREAT Youtube video of the exact machine/jig that I would need to build. It’s really a propeller duplicator.
