[PSUBS-MAILIST] identify titanium

[hank pronk]

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.
thanks' that is a good idea
Hank

Can you weigh the barrier by itself? Then it should be easy to determine whether it is SS or titanium.
