Carving the Spinner for Props???
Hello,
I have just finished my Sig Somethin' Extra and bolted on a Great Planes 2 1/4" Spinner on the front (the aluminum backplate type). I have also purchased some props for it, including an APC 11x5 Sport prop. Initially I plan to start with a Master Airscrew Nylon 11x6 and it fits just fine in the spinner cut outs, but the APC prop is about 5mm wider than the cutouts. I am considering trimming the spinner cutouts equally on both sides and am curious as to how it should be done. I understand that Sig makes spinners compatible with APC props, but I want to try and trim my current spinner. Is a dremel tool an absolute requirement or can I do it with the good old X-Acto knife?
Also, I have just switched props on my other plane and am wondering if I would have to retune the engine? The engine is TT Pro 46 and the prop is 11x6 (old prop was a 10x7).
Thanks in advance for any input.

Spinner fit
Try using a round file with a good tooth. Then wrap sandpaper around the file to finish. Make a template so you get the openings the same and don't debalance the spinner. The first few are tricky but after that it gets easier.

You can get a dremel for a lot less than the hospital bill to sew up your hand, as a friend of mine found out the hard way. Get the dremel, you'll find lots of uses for it in this hobby.

Thanks for the suggestions,
I will try to use a file to enlarge the opennings and if all else fails will probably get myself a Dremel tool. Gotta get it sooner or later.
Thanks again for the help!
