If custom fittings are made or required, make them from stainless steel 316 or better, from carbon fiber. Carbon fiber "hardware" is easy to make yourself and we will show some examples.
Build those parts from carbon fiber tape or tow with some UHMWP or SS bushings where needed. UHMWP means . . . (See building notes for complete text)
