Exactly. Mine failed after I had used the boom 50 times. A friend of mine
used to work at Sailboard Vacations, one of his jobs was to change those
twist locks. The "teeth" that go into the groove in the tail piece wear
off. You can fix it temporarily by wrapping duct tape around the piece that
is at the end of the boom arm so that the collar squeezes the "teeth"
tighter/deeper into the groove. It is very quick to replace them once you
have done it once. Cut the piece that is attached to the boom arm
longitudinally (hack saw or something), peel it off in one piece like
peeling an apple (with***driver for example), sand, mix and spread the
Kalex Urethane that comes with the replacement and push the new piece in.
The urethane expands when it dries up. Wipe it off from inside the arm
also.
