I have a Yellow Aircraft Zero Spinner, and I need to cut it for a 3Bladed Prop. How do you go about measuring for the cut so that the prop fits and the spinner is balanced.

I bought some CB Tatone Plastic Spinners from www.Mecoa.com that had to be cut, here is the link to the Spinner Cutting Instructions http://www.mecoa.com/faq/cbspinner/cut.htm

Thanks that looks like a good way, mine will be alluminum, but i should be able to use the same principle. Ian

Here are 2 videos I did on cutting a spinner...

I use a carbide tipped cutter for the dremmel instead of the drum sander. It works slick and does not dull. I've done at least 5 spinners with it so far.

Does the carbide tip work on Yellow spinners?

I ask because the Yellow spinner is far heavier (8.7 ozs to 3.7 for a Vortec 5" P-51 spinner)) and thicker (twice) than the usual aluminum spinner.
I have seen recommendations to use an air angle die grinder to cut the spinner openings.
So far my Dremel has barely dented the Yellow Zero spinner.

What do you guys use on a Yellow Aircraft spinner?
