Is there any evidence of galvanic reaction with aluminum/stainless/brass? Do you assemble with any sort of anti-seize compound to reduce that problem? Steve
If I get you right,
never had galvanic reaction with this combo but a thin layer WD 40 on to screws can
prevent this I guess.
Soon or later (after a few flight sessions) small amounts of Castor oil will find its way.
The hard stainless screws I use, never seize with the sort of Blind nuts I use too.
I allways replace screws and nuts from China (ARF/ARC) into stainless free screws (DIN Norm 9.8 or 10.3)
(which is an indacator for hard and stiffness) because much harder/better Quality.
Small amounts of grease Spray from a Bicycle Shop could be an Overkill.
The brass tube bushings just prevents crushing the maple mounts.
1/8 Epoxy sheet pads can do the same instead of Aluminum.
