Well Jon, I long ago discarded using clamps of any type on the elements.
After they're greased with NOALox, I use 2 stainless steel self tapping
screws to hold the thing. Have had a problem with any using that method.
On the boom to mast clamps, I use muffler clamps, and have started
"pinning" them by drilling a small hole through the end of each "U"
about 1/2" from the end ( put the nut on first inside the hole ) and
then, after attaching the thing to the mast, I place very small cotter
pins in each hole. I've never had a nut back off, but using this method,
even if it does, the worst thing which will happen is the thing will
slide down the mast. And even that is limited by a single clamp
installed about 6" under each boom to mast.
