I know old thread here, but I thought if anyone's still following this, how was this situation rectified?. I used the sandpaper trick and haven't had a problem, my spinner back-plate is fine, I actually tack glued a round piece same size as the prop hub about 150 grit to backplate where it contacts the hub, and used the pin-bolts, but I'm still leery of it I think.

If you recall, what did Tru-Turn tell you about how to fix it?

Thx
