Had about 8 feet of 1/2" vinyl tubing coming from the top of the motors going straight up into the air and hanging from my overhead I beams. Had the vinyl tubing connected to small inner tubes that had the air evacuated out of them. It was a cool day ( overcast, 60 degrees) . I ran the motors for over an hour, by the end of the hour the wd40 had climbed the whole 8 feet of tubing to the base of the inner tube. The motor pods were warm. If the sub had been in the water I don't think I would have had as much expansion of the oil. So I think that is going to work pretty good. Gives me a chance to run the batteries down significantly to see how my battery charger works with drained batteries, and how long it takes to bring them back up.</div><div> </div><div>Brian</div><div> </div><div> </div></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
