I happen to know of a fellow on another list who is wondering what to do with a broken aluminum mast.

Most masts are heat treated to strengthen them and any application of heat will destroy this strength. Consequently they can't be welded. Masts are made up of mechanically fastened sections however. The mating ends are squared and so that they fit smoothly together. A sleeve is made up that will fit snugly inside the mast, typically about 2 ft. long. The two mast sections are cleaned, assembled with the sleeve inside (typically with epoxy) and riveted together.

Is that how the original Kenyon masts were manufactured?

Just have to add to this mast discussion, concerning the heat and strength loss, I live in the Caribbean in what we consider hurricane alley and for 20 years I've seen and personally welded masts together in one instance 3 sections and that mast now 10 yrs welded and is perfect. Isomat and Kenyon both have sections that are welded, ie., . head ,spreader mounts, and shev bexes. Masts are spliced all the time by being sectioned and screwed 1/4 20 screws work fine and also welding . If you can find the size smaller mast and slice length ways a nice sleve can be made. Any metal worker with mast experience should be able to do this job. Aluminumis easy to work with as a carbide tip skill saw will cut it like butter. Don't believe the no welding ,and by the way 2ft isn't long enough ,4 ft, 2ft on each side is excellant 18'' per end or 36'' total minimum. Good luck
