 James, that looks great-the air bubble is good also.  Hank

 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?
ThanksJames
