I had earlier trimmed notches into the prop spinner to allow it to fit around the blades. I did some more trimming to approach the final shape. On the initial fit, the forward mounting flange did not fight tightly into the spinner cone. While it was pretty close, any misfit could cause a "wobble" of the spinner at the high RPM's that the prop will be spinning. I corrected this by applying release wax to the flange, then painting a layer of epoxy to the inside of the spinner at the contact point, then clecoing in place until dry.
