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?

due to technical difficulties. Well, okay, computer incompetence and
laziness.)

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?
