I have recently been asked to take some pics and do a step by step walk through in cutting Carbon spinners. I will start with the tools that I use.

Painters Tape
Dremel w/ cut off wheel and sanding drums
Marker/pen
Drill guide
#11 blades in a Hobby Knife
Paper
Contour Gauge (optional)

The first thing I do is drill the prop so it is in the position that you like for starting. Next drill the backplate so that the prop is between mounting tabs on the back plate. Now that this is done it is time to start with the cone. For the cone I first start by getting a good shape for the prop cut out. This can be done with a Contour gauge or slowly trimming a sheet of paper to the correct shape. Once you have the shape that you want, transfer the shape to a piece of tape. With the prop installed on the backplate measure from the trailing edge of the prop to the closest mounting tab. Use this demension to place your tape on the spinner. With the tape installed with the prop cut out shape I rough cut the opening with a Dremel cut off wheel. I then go back with a 1/4" Sanding drum to clean up all the edges and corners (do not make hard corners). With the cut out looking good pull the tape off and replace with fresh tape and cover the cut out you just made. Then take a pen and poke holes in the tape through the holes for the retaining screws. With a new #11 Blade in my hobby knife I will go around and remove the tape over the prop cut out. This will give me a perfect match for the other side. Remove the tape and spin the spinner 180 degrees. Place the tape on the spinner while lining up the screw holes. Again make your rough cuts with a cut off wheel and cleaning up with a 1/4" sanding drum. Now is the time to check the overall fit on your prop. Try to leave 1/16"-1/8" clearance around the prop. If you need to do some trimming around the prop, once you have one side done lay tape back over the prop cut and transfer to the other side. This will always give you the same cut out on both sides. The last thing to do before flying is go over the entire cut out with a nail file just to clean it all up. I have been flying Carbon spinners for the past 4 years and they are very nice and save large amounts of weight.


Sorry for the quality of some of the pics.
