Baaa!

You sailors with your cheap extruded aluminum spars, squeezed from a cheap
aluminum extrusion die!!!

Cheap, cheap, cheap! And not efficient at all!

The finest spars, aside from composites, is Simple Simon's double butted pre
stressed boom! Yes, that's right! The finest steel bike frames are made
from double or even triple butted tubing. The knowing Captain has himself,
with his very own hands, constructed a double butted boom. It's tubing wall
is thicker in the middle rather than on the ends! It's pre stressed to
overcome tensile loading! Only a genius could design such technology.

It's a shame that the good Captain is too modest to tell you these things
himself. It's a worse shame that you all are too ignorant to know it in the
first place. But the worse shame is the lack of respect you all have for the
good, noble Captain! Can't you all appreciate the great things in life?!?!

Give it up Sidney - I respect you for your vast engineering knowledge
but these weenies are so uneducated and simple-minded that they
can't honestly be expected to under stand systems involving physical
forces they cannot see, let alone comprehend.

If the boom was supported at the mid point, and a weight hung on the outer
end, would it retain the slight bend, or would it straighten out / bend the
other way?

Got news for you, Nil, "butted" tubing is thicker on the ends.

It's pre stressed to overcome tensile loading!

All the stresses were relieved when it broke. It's still broke.

Since you can't afford to live in a trailerpark that "repair" is the
trailerboat squatter equivalent of a junk car in the yard.

Close Rick,

I, myself, would compare it to the door of an old Ford Fairlane being
held closed with a couple of turns of wire around the post. It works.

Many of us have great respect for the Good Capt Neal!

In fact, I suspect you will find that the majority of posters have not
issued any critisism about the fine Capt's economically efficient repairs to
his boom.

Capt Neal would be a great source of inspiration to us all, if he hadn't
shown himself to be such a Simpleton in his blind support for the great
liar - Bush.


Regards

Good Lord. Last double butted tube I saw was thicker at the ends. Guess
Reynolds got it all wrong...

You're talking about the 531 double butted tubing. Double butted tubing can
be thicker in the ends or the middle.
Bobsprit is double butted and his tubing hangs in the middle!

BWAAAAHAAAA!!!!!!

Seriously Neal. Was the boom bent, as it appears to be in your pic, when
you added your pipe? Couldn't you have straightened it out? Or did it bend
afterwards.

It always bent when under load but it straigtened out when the load
was released. Sort of like the pre-bend in a mainmast that straightens
back out when the backstay is eased up.

If I were to take a picture of the boom now with the mainsail off, it
would look almost straight but it would have just a little angled
kink at the join. This little angle does no harm whatsoever.

Take most any production boom made for end-boom sheeting
and fit it with mid-boom sheeting without reinforcing it and it
will also show some bend under load.
