If you are going to add the electric pitch controller in the future, your spinner needs to be the kind with only a rear bulkhead. (tractor setup) 2. Make a cardboard pattern. 3. If you can make the pattern close enough, you can save the cutouts to fill the gap on the backside of the prop after the spinner is installed. This may not be easy to do, but worth the effort if successful. I did not do this and wish I had. 4. I marked my blade widths on the back plate (bulkhead), i.e. with the back plate and blades installed, and then set the screw locations based on that spacing, three between each blade. 5. Mark the backplate with a reference point and then inside of the spinner to match. I used a magic marker. You will keep this reference from now on to accommodate small differences in screw location. 6. The spinner should clear the prop by ~1/4" on the front and sides/edges. 7. You will have the spinner off many times to re-torque the prop bolts and adjust pitch, so don't use locktight.:-) Thinking of the basics, and I understand the reluctance to make the first cut..:-) Tommy James<>< _____ From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Kelly Troyer Sent: Sunday, September 12, 2004 10:02 AM To: Rotary motors in aircraft Subject: [FlyRotary] PROP SPINNER ADVISE NEEDED 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.
