My question pertains NOT to the gap between the aft edge of the spinner to the forward edge of the cowling. Rather it pertains to the gap on the inside between the conical part of the spinner backplate and the corresponding conical flange of the cowling. I'm wondering how wide does that gap need to be in order to prevent possible contact with up/down/side-to-side tilting of the engine due to its own vibration and/or flight loads?
How much does the engine move around up/down/side-to-side at the spinner?
I appreciate any informed opinions. And would especially like to hear the relevant experience of others with a WW prop (I understand Hartzell and others don't have a conically shaped spinner backplate like WW).
Thanks,
