Now, with the GIP inside as a sleeve and with the boom bales machine

This
way the boom is stronger than ever and no hardware hassles such as
locating
another gooseneck and end fitting for a larger extrusion, etc. were
experienced.

You're such a freakin' hammer mechanic.


Simply not so! Like, for example, the aluminum boom extrusion in cross
section is egg shaped. Now how does one fill, strengthen and support an
egg-shaped cross section with a round pipe? Answer: One cannot. So what does
one do? One uses three galvanized pipes. One large one to fit the round end
of the egg shape and two smaller pipes to fit the pointed spaces that
remain. One chooses sizes that fit snugly but don't have to be hammered
home. That's not hammer mechanicing; that's engineering. The three pipes
where coated with slippery silicone rubber sealant before being slid home.

You are correct - it is not "hammer mechanicing" (whatever that is) it
is called, in the trade, "Shade Tree Engineering" and is carried out
by people without a clue as to what they are doing.

You seem to be saying that in order to attach a fitting to an aluminum
boom that, somehow, the boom must be reinforced with internal tubes -
three in your case. Strange that the millions of sail boats presently
on the water all don't have three joints of water pipe stuffed in the
boom. In fact the vast majority have no reinforcement in the boom,
just properly designed fittings bolted to the boom.

If you want some added evidence that aluminum beams do not require
reinforcement with water pipe you might look at the aviation industry.
In the twenty-some years I worked on aircraft I never saw a single
spar or beam with a galvanized pipe reinforcement, and I worked on
some of the more advanced aircraft of that period.


You have your pee-pee size little boat with a duct taped refridgerator,
etc and pretend to be a sailor.

Electrical tape, inch wide professional quality electrical tape! Again, the
refrigerator is repaired better than new. It took the original aluminum
tubing of the evaporator four years to corrode and develop pinholes whereby
the refrigerant leaked out. Now, with the tightly wrapped tubing completedly
sealed from the elements not only are the pinholes stopped from leaking but
further corrosion is also stopped.

Strange... I had a fridge in my sail boat. Put it in about 15 years
ago and, as of the time I sold the boat, a month ago, never had to
service or top up the refrigerant.

Obviously you had a **** poor installation (probably using galvanized
water pipe) that caused the corrosion.

Successful sailors are clever, enterprising and ingenious. We think out of
the box and never believe any lubberly ideas - ideas like if the
refrigerator breaks then throw it away and buy a new one. That's a workable
solution for lubberly dummies who have more money than brains but for we
frugal sailors who enjoy using our hands and brains, the better way to go is
to fix things and fix them better than they were to begin with.

You might be using your hands but the other part of your claim is
highly questionable, or at least not demonstrated to date.

I must admit you can be amusing once in a great while.

It's quite revealing as to the lubberly thought process when one of them
confuses initiative, creativity and enterprise with humor.
