I recently noticed that both of my elevator counter weights are slightly loose. I hopefully have embedded a photo showing their arrangement below. It was built and installed according the plans. I was an early 7a builder and the design change soon after I started. The bolt you see in the photo has a locknut on the the other side that can't be reached without removing the elevator tip fairing, so there is no way to tighten the assembly with a fairing removal...which I really don't want to do.
Has anyone addressed this issue? Any ideas on how I can bond the periphery of the lead weight to the aluminum with the limited access you see. I want something that will bond well and add little weight.
