Expanded Prop/Spinner Coverage
For those of you who just need to see more about how the spinner was fitted to the propeller... Our Catto is 68" diameter by 82" pitch.

We added 2 BID of glass around the periphery of the back plate to get a better interference fit with the flow guide. This is one of Ken Millers (www.long-ez.com) spinners made from carbon fiber. The position of the flow guide was fixed, and the blade positions were marked onto it, and subsequently, the dome.
Fixing the position of the flow guide.
Then the back plate was permanently bonded to the flow guide with flox. This is possible since the prop doesn't have nuts, the extension is threaded. Then we had to make templates of the prop blades (horse shoe style) so that we could cut the openings in the dome. The back part of the cutout will then be bonded to the back plate so the dome can slide on, and be attached with screws and nut-plates.
