Boom heads working loose

Boom heads working loose

Post by Maarte » Wed, 07 Oct 1998 04:00:00


Hi,

Been having this problem with the screws connecting the tubes to the
boom head working themselves loose despite frequent re-tightening,
resulting in a wobbly connection and quick deterioration and breakage
eventually.

This occurs with any type of boom I've ever sailed, and was even worse
on the push pin booms than on the screwed ones.

Does anyone know of booms that don't have this problem or a way to
prevent this problem. (anyone tried glueing the boom-head to the tubes
instead of screwing ? I'm thinking of doing just that, what would be the
best way to do this ?)

Do carbon booms have this problem and if not, how long does a carbon
boom last compared to an aluminium one (twice the longevity at twice the
price and they're a sound investment).

big waves to ya, Maarten

I use a Wiechert (sp?) boom that I bought about 5  to 7 years ago. No problem.
I have no idea of who sells these presently.

Weichart I presume, seen a lot of them broken, but if the front
connection is solid then I want to know how it is constructed.
WHat connection type do they have ? (Screws ? type of***etc....)

My boom heads attach to the boom with a metal button.  The head is aluminum and
hard plastic from what I can see.

I used to rivet my boom head with some special metal rivets I got from a
yachting shop, supposed to be stronger and more corrosion resistant than
stainless. Trouble is modern heads are pre drilled with countersunk holes,
rivets don't seem to work in these as well. Self tapping into 1.2 mm of Al.
doesn't seem like a real secure idea, some heads have come with a plastic
insert that goes inside the Al. tube. The***then has a bit more to grip
on. Does your boom use this principal? If not it would be worth a try, as
once you glue it is much harder to repair. If gluing is your last option I
would use an epoxy glue i.e. araldite, but clean both surfaces first.
Good luck Mike.

Try Loctite - it is a thread locker and will prevent fasteners from coming
loose.

If you're taking the glue option, use Loctite 638.  Providing that the
surfaces are
clean and the gap between them is less than 0.5mm it'll be stronger than
threadlockers, araldite or rivets.
