<div>Hi Graham,</div><div>I estimate your pods to be almost neutral with three batteries if the pods are made from 1\4 in plate. Your problem is coming from the heavy steel framework and steel mbt's. </div><div>Just keep adding weights inside the hull until it is stable. Then try to sink her, hopefully it will not sink. Once it is stable just keep adding weights until it sinks. Once you can get it to sink, remove the weight and add it up. Then start filling your pods with that amount of lead.</div><div>Hank</div><div><br></div>

My housings measure six feet long by fourteen inches I can not calculate how much weight I need to make these negative buoyancy I have three leisure batteries in each housing plus one hundred and fifty pound of lead on top. this does not counteract the upforce which each housing is subjecting my sub to. I am lost as to how I can over come my problem as she is determined to roll . can some one help me please.</p><p class="yiv7413673959MsoNormal"> </p><p class="yiv7413673959MsoNormal">regards </p><p class="yiv7413673959MsoNormal"> </p><p class="yiv7413673959MsoNormal">Graham</p><p class="yiv7413673959MsoNormal"> </p><p class="yiv7413673959MsoNormal">Pictures of Casper 2 being built are on the site if you need to look at what I have built.</p></div></div></div>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br></div>
