3-30 Spreaders
I am finally ready to re-step my mast, completing the Alan Storey beam
replacement that I started in October. This was supposed to be a couple
of weekends, but things quickly got out of hand.
My question to the list regards the tangs that attach the spreaders to
the mast. These are very substantial items that are welded to the mast.
The aluminum plates holding the spruce spreaders slip between an upper
and lower tang, and are held there by two large pins on each side. One
both sides of my mast the upper tangs are tipped up so the the
spreaders lie flat against them when properly installed, ie, bisecting
the angle of the upper shrouds. The lower tangs on each side are
perpendicular to the mast itself, causing the lower plates to lie
against them with only the ends actually touching the tangs. Keeping in
mind that the 3-30 uses the same mast section as the 40's, this may ll
be a moot point, but here goes. Should I, a) ignore the whole thing,
put up my refurbished spreaders and hope to get another 30 years out of
them; b) attempt to bend the lower tangs, which are 1/4 or 5/16th stock
and massively welded in place, using a BFH or some other tool, or c) do
something else? I am inclined to think "a", based of the great strength
and lack of flexibility of either the aluminum mast or the tangs.
Hopefully someone with more analytical skills than I will be able to
give me some guidance.
This all started when I ordered one of Alan's excellent beams, and set
out to follow his simple photgraphically illustrated directions. After
dropping the mast, removing the headliner, and cutting out the port
settee, I ran into my first challenge. When driving the compression
post, under which the beam resides, off its pedestal, I cut all of the
wires running through it and up the mast. No worries, I'd planned to
replace the coax and wire a new masthead light anyway, and the steaming
light was to be replaced with one with a foredeck light, Off I went to
West Marine, where I purchased all the stuff I needed and proceeded,
with the help of a coworker, to cut off the top of the pedestal and
expose the beam. Now Alan had a set of blueprints, and had already made
and replaced the beam in Chimera, his 3-30, so I knew I was going to be
OK. Until, that is, that I found that my boat had been assembled
without the shims at the ends of the beam which allow it to be
installed and removed. We cut the end off the beam with a Sawzall, and
with some encouragement from Alan, machined the end of his 316
stainless beam to fit into the boat. It worked, and we were able to fit
the new beam and begin undoing our mess. Stringing the cables from the
panel to midships, and the through a hole bored in the top of the beam
was pretty straight forward. My coworker then reglassed the top of the
pedestal, returning it to it's original height, and color matched the
gelcoat to the original. From there we routed the wires up the
compression post, and through the coachroof. We were able to raise the
roof sufficiently to re-install the post by using a pair of car jacks
and a couple 2 x 4's.
Things were going swimmingly, and after painting all of the unfinished
interior of the hull with gloss enamel, I reinstalled the settee and
got ready to deal the the connections at the base of the mast. All of
my new toys were in place, the combo steaming/deck light, a new
masthead light, new VHF antenna, and windicator. This was really cool.
Just to be on the safe side, I took a piece of coax and a connector to
the local electronics shop for a refresher of soldering. The guy took
one look at the coax and said, "You cant use this, it's the wrong
stuff. It's for TV and it won't work with your VHF." After regaining
control, I allowed as I didn't think it would be possible to do that
without undoing all we had done. He said, "sure you can, just solder
the new cable to the old and pul it through." I told him I thought it
was impossible, and agreed to pay him his fee to do that and make the
electrical connections, since apparently the coax joints are critical
to decent reception, and the 8 20 ga. wires in one cable for the wind
bird were beyond me. Three days later he called to say that all was
done on the boat, but he had forgotten where at the yacht club i had
told him the mast was stored, and had not completed that end of the
three cables. That was in early December. What with the holidays and
the Seattle boat show, I kind of laid off him, knowing that he was
busy, but last week I swallowed hard, paid for his travel time and
asked him to fix it by the weekend, please. He did, and yesterday I was
ready with a couple of buddies to "git 'er done." Then came the gale
force winds and torrential rains, and the mast stayed in the yard.
Today has been bright sun and some damn football game, so of course my
help has vanished. I have tomorrow off, and WILL put up that mast.
Any advice before I just go and do it...?
Thanx,
