 Alan,My first calculation was 150 lbs different but I missed a step.  My next attempt with no interruptions, lol  I got a difference of 83 lbs buoyancy per tank.  I rounded the numbers.Hank

 Hi Graham, 
can you just confirm those dimensions before I calculate.
Originally you said your new pods were 6ft long ( 72")
In the latest email I am reading that you are now saying they
are 57 & 1/4" long! Or is this the old pod length.
Once I get the dimensions right I'll calculate your old pod
thickness at 1/4".
We will get there eventually.
Cheers Alan
