I cut the spinner to fit the prop. No instructions came with the spinner so I measured the circumference of the base of the spinner and divided by three, then located the measurements on the spinner. I rough cut the openings in the spinner using a Dremel Tool cutting disk, then sanded them to final shape using the Dremel drum sander. I mated and drilled holes through the spinner and backing plate. I’ll attach the spinner to the backing plate with #8 offset nut plates. Another trip to the parts store to get the nut plates. Ready for final painting.
