<div>Alan,</div><div>Thank you for the input. I went with the brass because I was in a hurry and Gamma will never see salt water. The small tank can be fed continuously from the main tank. I will leave the air supply on until I reach bottom then shut the air supply off. I did know to invert the regulator but did not know about a tube that has to be added. Cliff did not mention that? I am sure that air in the motor is better and will take less battery power also. So you think I should air compensate the motor and risk the arm actuators? You have a good point that the actuators would be aired up, I did not think of that.</div><div>Hank</div><div><br></div><div><br></div>

This makes me think I should air compensate that thruster instead of oil. The system works with a small 3L air holding tank that is maintained at 300 psi from the main HP tank. I am not sure if I should risk feeding the thruster from the small tank, in case the thruster seal leaks it could cause the arm to flood. </div><div>Hank</div><br clear="none"></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="yqt1161271544" id="yqt72491">_______________________________________________<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>
