[PSUBS-MAILIST] Oil Compensator

[hank pronk via Personal_Submersibles]

Jon, Do you have the shaft that used to screw into the motor?  if so, you can cut it down to a couple inches long and put a waterline compression fitting on that.   Then reduce from the compression pipe thread.  Or you can thread the inside of that stub shaft with a pipe tap and reduce from that, providing it is the heave fibreglass shaft.Hank

 Hi Alan,
Cliff's custom adapter is more than I want to get involved with.  I'm thinking the simple system that Greg described, using vinyl tubing or even rubber hose for an air compensation system.  I either need 1 3/8 tubing (reasonably priced) or need something to thread into the shaft knob (like Cliff's adapter) that will reduce the diameter to something more reasonable.  Anyone remember what the specs are for that thread?  Too bad it wasn't just pipe threads, that would be easy.
Jon
