I'm in the U.K. and finishing off my Long-Ez project. I'm looking to acquire a ground test prop (scrap prop, NOT for flight etc.) to run the engine up in my back garden. I have a Silver Bullet prop but don't want to damage it by getting fodder pass through it (like stones, pets or children!)
The specifications for my Lycoming O-320 B3B (160 HP):
Propeller/Extension Flange: SAE #2 (4.75” BC dia)
Rated Horsepower 160 @ 2700rpm
Prop Bolt Diameter 0.4375" (7/16")
Drive Lug Diameter 0.625" (5/8")
Drive Lug Length 0.610" ( ~5/8")
Any help or suggestions would be appreciated.
