<div>Alan,</div><div>If I were in salt water I would worry about corrosion also, but in fresh water they are fine. Having said that, I will make an oil filled enclosure. There is not a serious risk if a valve failed. Gamma can surface with the drop weight and the escape pod bladder.</div><div>Hank</div><div><br></div>

I said no, but that got me thinking, and I may not have realized that I was getting a air lock. Normally I dive Gamma heavy with no issues but at Lake Tahoe I was diving very close to neutral. The problem I was having at Lake Tahoe, was the sub leaning uncomfortable while submerging. I blame that on the weight of the sub and since the sub was light it could not push the water out of the vent lines casing a blockage. I like diving closer to neutral now so I installed 4 solenoid vent valves as an experiment. It has solved the problem completely. In fact I only need two valves to make it sink perfectly now. With all four valves open plus the two original valves open, the sub dives in 1 min and 30 seconds. Slow compared to Alec's sub but good for Gamma.</div><div><br clear="none"></div><div>My next challenge is to install a bigger port in E3000. First I am planning a proper poured concrete test pool in my new shop. Then I will dive E3000 a couple million times in the pool. Then I can work on a larger port assembly.</div><div>Hank</div></div></div></blockquote></div><blockquote type="cite"><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" target="_blank" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br clear="none"><span><a rel="nofollow" shape="rect" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br clear="none"></div></blockquote></div></div><div class="yqt8146580609" id="yqt21830">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div></div>
