[PSUBS-MAILIST] Pressure proof motor

[Alec Smyth via Personal_Submersibles]

I don't plan to prep the shaft surface at all. According to the Parker
documentation, the seal will polish the shaft so that it improves with use.
We shall see! We're planning to run extended tests in an instrumented
pressure chamber. Eventually, of course, the shaft would wear out. But
consider how many hours we put on our subs compared to the hours an avid
fisherman would. At least on my part, I probably put as many hours on it in
a year as a fisherman does in a day or two.
