I am going to make a fairly large fishing gaff from some of my extensive
scrap box. Trying to keep it as light as possible I have selected 4' of
6061 1" aluminum tube for the handle and formed some 5/16" 316 rod for
the hook. The plan is to machine two aluminum bushings. One a slip fit
into the tube at the end of the shank and a second as the hook exits the
tube. The bushings will be pinned to the tube but I can't figure the
best way to tie the hook to the bushings.
I have never had success with brazing or soldering stainless and
aluminum. If I pin them I will be reducing the steel right where the
stress is highest. Only thing I have come up with is to drill the
bushings for a tight interference fit, heat them and slip them on the
hook before they cool. Any other suggestions?
