Re: [PSUBS-MAILIST] Phone # for Mine sweeper hulls
My all time favorite solvent has to be
trichloroethane. I just went looking for some recently, without success. Banned
as an ozone eater. I can suggest a few readily available noxious
chemicals that you might try. Kerosene is fairly cheap, fairly benign, and
fairly slippery. Turpetine is a non-liver-eating replacement for turpentine.
If your glue is an old pine tar material, turpetine may cut it. Denatured
alcohol may work better than isopropyl, but it still evaporates too quickly for
my taste. Mineral spirits (paint thinner) might be worth a try. Paint stripper
can work miracles, but OSHA and the ozone hole have taken some of the fun out of
that, too. Do you have a big fan, and somebody to spot you?

Subject: [PSUBS-MAILIST] Phone # for Mine
sweeper hulls
A chap "down under"
wanted the phone # for the place that sells the mine
sweepers. It is
Lague Sales, Robert Lague 209-825-2582. I think
he
wants $250 each. If you work out a deal with him to ship one to
you, I'd be
glad to go and pick out one for you. (Just to make sure
you get the best of
the pile). Some of them have some pretty deep
marring where they were
dragged on the sand. I'd look for one with
no damage.
I cut one in half the other day and took out the foam
blocks. They weigh 600
lbs, total, without the foam. Did the
math calcs to estimate how much it
would displace. Figured to be
4400 lbs on paper. After I cut it at
"station 10", I stood
each half on a large scale and filled them with water.
The front
10ft. weighed in at 3200 lbs and the tail (8'10") weighed 1100 full
of
water. Total weight = 4300 lbs. The first 14" of the nose is
sealed
from the rest and did not fill with water. I don't know if it
is full of
foam or just empty. There is a 4 inch steel tube across
the inside at
station 6. There is a glue substance (very sticky yet
after 50 years) on
parts of the inside, apparently to hold the foam in
place during assembly.
Tested acetone, alcohol, gasoline,
detergent, and tolulene. Only tolulene
will cut the glue and then
only with scrubbing. Heat softens it so I used a
heated pressure
washer to get alot of it out but that was a VERY slow and hot
process.
I'm not willing to climb inside with a gallon of tolulene
and
start scrubbing away.
Any suggestions?
