[PSUBS-MAILIST] Oil Compensator

[Jon Wallace via Personal_Submersibles]

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
