[PSUBS-MAILIST] identify titanium

[hank pronk]

Jim,
No makes no difference, it pressure tested to 1,500 feet-ish , that is plenty.  When I brag to my coffee buddies about my magnetic coupler, it sounds better if I can throw the word titanium.  :-)

Jon,
>The barrier is welded to a heavy ring that secures it to the housing.  I could submerge it in water and measure the displacement to get the volume.  I never thought of that,grrrrr.  It is all assembled and going in the sub in a few minutes, so I will get a volume of it next time it is apart.
