I cracked three spinners of the same type as Mark's on my KR, each on the first flight with that spinner. I eventually mounted one with a front bulkhead similar to the one Larry is using. After the first flight, I was also seeing quite a bit of aluminum oxide "smoke" inside the spinner from it chafing. I ran a single piece of teflon tape around the front bulkhead to prevent chafing and to ensure that it was a snug fit. End of problem.

It did absolutely no damage except for a small scratch on the prop. The contributing factor to this event was the lack of a front bulkhead spinner. Do not fly without one. >Mark Jones ++++++++++++++++++++++++++++++++++++++++++++++++++++++ I second that suggestion. Also, when you install the front bulkhead, install some threaded screws with nutplates to secure it. When I first installed my spinner I did so with just a pressure fit on the front bulkhead. When I removed my spinner after several hours of flight there was considerable galling from movement between the spinner cone and the bulkhead. Needless to say, I secured it when I mounted it again. I used #10 stainless screws ( round headed bolts) on the back plate and #8's on the front. I've had no problems since in the 130 hours of flight time. As to Orma's problem on the front bulkhead not fitting, when you order your spinner, you give them the prop thickness and they size the front bulkhead to fit the spinner for that prop. It won't work with any other thickness prop.
