[PSUBS-MAILIST] Idea..?

[Alec Smyth via Personal_Submersibles]

Hi James,

I think with the taper, this would tend to push in and jam. The idea is
neat, however, and would probably work fine with a step instead of a taper.
On the other hand, does an O ring sealed through-hull ever fail
catastrophically? I've had the odd drip, but that's all I've bad as I've
seen.

Best,

Alec
