Guys I am about to cut metal to fit a 16 inch spinner to my three blade
"IVO" propeller and would like any advise on your favorite methods
of making a pattern of the prop to avoid ruining a very expensive piece
of aluminum. Attached is CDP (cheap digital photo) of what I am
dealing with. All comments and advice appreciated.
Thanks,

Hi Kelly,
Having flown behind a couple of IVO's, my 1st piece of advice (if your plane is capable of flight faster than about 160kts) is to start with another prop. :-)
My 2nd piece of advice is: don't use a spinner, since you will need to check the integrity of the hub before every flight. When I tried the IVO, the company actively discouraged the use of spinners for that reason. (return to #1)
As to actually fitting the spinner, I fitted the prop & both front & rear bulkheads to the hub & used stiff paper (old file folders), cut into strips, & tape to get a rough contour around the blades, then transferred the pattern to the spinner. There was still a lot of 'cut & fit' involved.
