[PSUBS-MAILIST] Yet another compensator method

[James Frankland via Personal_Submersibles]

Hi All

Getting Jodie B ready for diving in the next week or so.
I have changed the motor compensator yet again as the last enclosed one
didnt really have a proper flexible part and I think the oil expanded a bit
over time and leaked out through the seals.  Just a tiny bit, but enough to
put some air back in the pipe.

Anyway, the new method is simply a tube with belows.  These are from a
toilet flush and have been sitting full of oil for a couple of weeks to see
if anything happens.  They seem good, so i have installed them. The motor
is completely filled with oil and the bellows have a small amount of air.
They compress easily, so should provide pressure compensation while also
allowing the oil to expand if required.

The bellows will be covered with an open ended tube for protection.  Just
got to make a strap for those.

Any comments?
Thanks
James
