Hi! Fred
Sorry but I'm not "your uncle" but I do have a perfect removable fix to
all the problems which doesn't have any doubts about the mixing of glue
and metal components. I have already suffered it the hands of Loctite on
the nose wheel yoke spindle if you remember? It cost me 18 months
flying, thanks but no thanks.
Regards
BOB Harrison.
