I ran into an issue swapping C/S propellers on my RV-7A...now I don't have sufficient clearance (or any) from the nose of the cowling to the spinner backplate. Assuming I have the spinner backplate mounted as close to the prop hub as possible I thought I would consult the collective brain trust for other options. I posted in the RV-7 specific section and another RV-er suggested shimming with extra washers at the engine mount to engine interface, that got me to thinking about shimming at the engine mount to firewall location. I understand it would move my nose gear forward a commensurate amount and also shift my cg forward but that is actually a good thing in my case. Also possibly introduce some new cowling to engine component interference in the forward cowling area. Would placing a few large area washers between all of the mount points and firewall have any other implications? Any ideas on a better way out of this situation? The only other solution I can think of is to rebuild the forward end of the cowling and I hate to mess up my pretty paint job!
