Hello All: I have 10-32 screws with 8s size Tennerman Washers as attach
fittings. The cowling holes have worn slowly but surely and now I know it is
time to fix this vibration problem. I like the size of the 8s but I suspect I
really should use 10s. They are unpainted and not bonded to the cowling. My
questions are 1) I think the solution would be to epoxy the Tennermans (larger
size ) to the cowling now that the hole is getting too big. 2) Should I flox
them in place from inside for a more secure bond? I haven't been bothered
before now with the washers "free floating" for lack of a better word.

Larry,

If your Tennerman-style fastners are the "clip" type, the floating
over the holes serves as a self-alignment process for cantankerous
cowlings and you might loose that benefit by epoxying them in place.
Hard to say if that's important without seeing your machine. Could
you install nut plates instead? They would still internally float
making it easy to align the cowling screws. You haven't lived until
you've pulled annuals on 40 year old Appaches. Talk about cowling
problems...

Good luck
