It's nice to be renovating the sub after an 8 year hiatus. All new domes and other viewports have been fabricated. New coms and thrusters too. Looking forward to diving again late summer.</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1498092335534_3823"><br>Greg</div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1498092335534_3829" style="display: block;"> <div style="font-family: verdana, helvetica, sans-serif; font-size: 13px;" id="yui_3_16_0_ym19_1_1498092335534_3828"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1498092335534_3827"> <div dir="ltr" id="yui_3_16_0_ym19_1_1498092335534_3826"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1498092335534_3825"> <hr size="1" id="yui_3_16_0_ym19_1_1498092335534_3832"> <b><span style="font-weight:bold;">From:</span></b> Jon Wallace via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, June 16, 2017 12:32 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Test at boat yard<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1498092335534_4091"><br><div id="yiv7815275462"><div id="yui_3_16_0_ym19_1_1498092335534_4095"><div style="color:#000;background-color:#fff;font-family:times new roman, new york, times, serif;font-size:16px;" id="yui_3_16_0_ym19_1_1498092335534_4094"><div id="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14373"><span></span></div><div id="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14373"><span id="yui_3_16_0_ym19_1_1498092335534_4093">I am sure you will get the kinks worked out.

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="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14291"> </div><div id="yiv7815275462yui_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="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14396"> </div><div id="yiv7815275462yui_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="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14366"> </div><div id="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14365">Brian</div><div id="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14364"> </div><div id="yiv7815275462yui_3_16_0_ym19_1_1497629837802_14315"> <br clear="none"></div></div></div></div> </div></div><div class="yiv7815275462yqt5564310425" id="yiv7815275462yqtfd27000"> </div></div><div class="yiv7815275462yqt5564310425" id="yiv7815275462yqtfd21075"> </div></div></div></div></div><div class="yqt5564310425" id="yqtfd83882">_______________________________________________<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" id="yui_3_16_0_ym19_1_1498092335534_4113">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" id="yui_3_16_0_ym19_1_1498092335534_4115">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
