I like the idea of the Ernst plate. Did not know they were available. Washers do compress into the wood, that was always a concern. I did go one step further and took a dremel to one side of the elongated holes on the supplied mount and removed a little bit on all four slots. It resulted in the mount going flush with the side of the fuse and helped center the shaft in the cowl. Does "Quantum" have a website? Thanks, Joe
