But now I'm just concerned with having a working sub for the time being. When I made the forward trim tank it needed to be able to take the same pressure of the hull but I think I over did it a bit and used too heavy a gauge pipe . I'm not getting the buoyancy that I need , it was difficult to calculate what the weight of the ferro cement would be in water up in the front there. </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14291"> </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14285"> I ran most all the air out of the MBT and at the end the nose took a nose dive. I think the best thing would be to put a big cylinder of synaptic foam in place of the tank I have now , that way I could add extra compressed air cylinders if there is too much buoyancy , or lead to find the balance point. </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14396"> </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14367"> One thing that I'm extremely pleased about the freeboard when the MBT is filled with air, I have nearly 4 ft to the top of the hatch.</div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14366"> </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14365">Brian</div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14364"> </div><div id="yiv0214735299yui_3_16_0_ym19_1_1497629837802_14315"> <br clear="none"></div></div></div></div> </div></div><div class="yiv0214735299yqt5564310425" id="yiv0214735299yqtfd27000"> </div></div><div class="yiv0214735299yqt5564310425" id="yiv0214735299yqtfd21075"> </div></div></div></div></div><div class="yiv0214735299yqt5564310425" id="yiv0214735299yqtfd83882">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a rel="nofollow" shape="rect" id="yiv0214735299yui_3_16_0_ym19_1_1498092335534_4113" ymailto="mailto:Personal_Submersibles@psubs.org" target="_blank" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a rel="nofollow" shape="rect" id="yiv0214735299yui_3_16_0_ym19_1_1498092335534_4115" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br clear="none"><br clear="none"></div></div> </div> </div> </div></div><div id="yiv0214735299DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br clear="none">
