Herb, I know you, FWIW......

I have assembled many gliders over the decades......
At least once a season, clean fuselage pins and lube....same for spar pins and bushings.......
A "slightly smaller" alignment pin (usually concentric, no real need in 99.9% of times for cam type), helps for first main pin alignment.
Clean pins and sorta decent lube is about all that is needed.......
