Spinelli star 14 3/4 27 pitch prop 4 blade...

[Twin27Advantage]

Does anyone know how the center of the prop is assembled? It is suppose to be a solid hub prop and it is but it actually looks like a pressed in insert. With the drive in gear you can spin the prop. The prop shaft stays still but the center of the prop or hub is spinning in the prop. It is not the standard torque flow hub, it looks like something by spinelli.

I am curious if it is repairable.

Thanks for any help!

I have a feeling it is rubber hub, there are no signs of weld. A buddy from MI Wheel picked it up to bring in to work tomorrow. At first glance that is what he thinks it is.

It didnt last trying to get on plane.

Thanks!
