I have this tank, which I craned today:

http://igor.chudov.com/tmp/Stainless...-Hull-Tank.jpg

(craning was done before wine consumption)

It is carbon steel on the outside, stainless inside, cork
insulation in the middle.

I need to separate stainless and carbon steel for scrap.

My question is how is the inside typically attached to the
outside.

My best hope right now is that the inner hull was simply
inserted into the outer hull with very little welds between
them. So, I hope, I can just make a circular cut on one side
where the mouth is, and pull out the inner body from the outer.

Makes sense?

i

Id hang a quanity of C4 directly in the center, both vertically
and horzontally and then set it off. Will crush the cork and
break the welds

I _really_ want to see the video of that.

It woild even be cooler if the tank was filled with water.
Wouldnt need more than an oz or 2 of C4 depending on the size of
the tank.

(Grin)

Wouldn't a bit of det cord do the trick?
HE-tech wine bottle neck removal simulation.
Pop the end and drag out the inner tank.


Probably work fine, but Id use "trim stick" instead of primacord. Its
got a more focused energy path.


Wish it were available to play with and learn about.


If you're talking about linear shaped charges , they are fun . Basically a
tube full of explosive with one side dented in to form a vee shape , and
they work better if you stand them off the surface to be cut a little . It's
been over 30 years since I worked at Thiokol , but a lot of that kind of
thing just sticks with you - like the time we "disassembled" a shed with an
8 lb block of C4 Poseidon propellant . There were a few pieces bigger than a
toothpick ...
