Extruded spars don't "Cut the Mustard"
 

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.

Good Lord. Last double butted tube I saw was thicker at the ends. Guess

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!

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.

That shouldn't be necessary unless you're changing tuning for conditions.
Aren't Etchells pretty well built? If you set up for heavy air, do you have
to slack off the rig when you put the boat away, or will it go slack on you
if the boat is left for a week?

Maybe I'm more spoiled than I realize, I hate boats & guitars that won't stay
in tune pretty much indefinitely....

We change tune cap for every race pretty much, and adjust lowers
during the race as conditions change.

I'm not a big fan of that, but in some classes I guess it works well enough to be
worth the bother. The paradox I dislike is that to flatten the main you have to
loosen the lowers. One thing I have done is tighten the lowers for a chop, but it
was probably more of a psychological gain.



We drop the lowers off at the end of the day but caps stay as set till
the next week.

Doesn't that bend the mast while it sits parked? Other boats I've seen set up the
spi pole uphaul to the foredeck tightly, opposes the lowers. Not sure that's worth
the bother either.

One place it could make the biggest difference is if you could set the boat up for
power off the starting line, when you are likely to be trying to accelerate and/or
get in a pinching contest; losing a few inches here can mean losing many boats.

Yep, a pita!
Our boats are stiff enough to stay in tune.

That's good. I struggled with a few that were not, rebuilt two so that they were.
It still makes me wince to see some of the static loads people casually put on the
boats.

You should try out a good guitar some time. The only times I have to tune up
are when putting on new strings (which I confess I don't do often enough),
getting ready to jam with somebody whose instrument is slightly out of tune (or
is a cheapo that won't tune properly), or when it's been subjected to noticable
temperature change. Sitting in their cases in the closet, my guitars (not
cheapos but not really anything to brag about) don't go out of tune even
slightly.

BTW if you have a hard time perceiving whether two strings are in perfect pitch
with each other, learn the bell tones. The harmonics are more dramatic, easily
recognized even by the tone deaf.

It mat not be the finest but for size I bet there isn't a heavier one. I
just hope it doen't pull the corners out of his new Main.

I wonder at what wind speed he has to use the topping lift to get
horizontal wrinkles in the main?

Also wonder it the topping lift put enough bend in the mast to pull the
belly out of the main he is trying to put draft in?

Wonder if he has trouble getting Sag in the forestay with the weight of
that "Finest Boom"?

I wonder if you would like to comment on these conditions Sidney, since
you seem to be so well voiced on this boom.

Would you also like to state what size "Sock" you are?

I'll wait to drink on that until your reply. I should be well dried
out by then:^)

Remember the comments about the Capt who is a Bully and an Ass. Thought
I'd mention I'm not to fond of the product produced by a Bull's Ass.

OT

Ok OZ,

Just so DSK doesn't get lonely on the 'net, the question that comes to
my mind, is what happens the forestay and backstay tension? When you
have enough tension on the backstay and forestay to bend your boat like
a Banana, how in the world do you and the "KING" change sail shape to
match changing race conditions?

OT

Not likely. Neal rammed a telephone pole down his mast for extra strength.
