Help me out.. Found this at the bottom of a box of items bought several years ago. Believe it to be a prop tool of some sorts. Any help in how this is used would be greatly appreciated.
I have an identical one that came with one of Huey's Dial-a-Prop systems. Its used to equalize pitch and/or diameter relation between separate blade on a prop. I haven't used mine in years.
It is part of the Steve Muck pitch gage that is the part for getting the dia the same on both blades good for nitro 3/16 shaft .I have the completeset much easyer to read than the Huey which I also have.
