[PSUBS-MAILIST] Compensation Method Again...

[James Frankland via Personal_Submersibles]

I know what you mean Alan.   Bigger bellows would allow more leeway.  But i
think as long as there isnt more air in than the volume of the bellows,
then i should de ok.

I am doubling up the bellows on the aft motor.
