Netters, I spent the better part of the last two days installing my spinner. I'll share the procedure I used to mark the cut-outs on the spinner that required no measuring and turned out to be quite accurate.
I first made my templete for the cut-out as directed by the instructions that came with the spinner. It was simply a copy of several pages from one of the Tony Bingelis books. It has you make an oversize cut-out on poster board or other heavy paper. You place it around the propeller and then use many pieces of tape to further refine the cut-out before transfering the final shape to another piece of paper. At that point I placed my spinner on a piece of poster board and traced two separate circles around the spinner. I placed the templete on the spinner and marked the cut points for the back edge of the spinner and then transfered these marks to circle number one. I cut this circle out and folded it in half twice with each fold at 90 degrees to each other. This gave me the exact center of the circle. Using a ruler, I drew a line from each of the two marks through the center point to the opposite side. This gave me the location of the cut-out exactly 180 degrees from the first. I placed the cut-out circle with the cut-outs marked onto the second circle and transfered these marks to extend outside the circle. I placed the spinner onto the second circle and transfered these marks to the spinner. Cut the propeller holes in the spinner undersize and slowly refine them to a perfect fit. Don't forget to tape your propeller so it doesn't get all scratched up in the process. My spinner is installed and looks good. Good luck. Your results may vary!
