And thanks for sharing progress - I find these updates very motivating and help me remember I get on with my projects too.<br><br>I've recently ordered a 2000lb Aluminum Gantry Crane. I figure the biggest chance of accident with when moving the sub. I had originally planned on moving it with two engine hoists, but this look like a recipe for problems. Also, since I'm normally working on my sub alone, I need something I can safely use by myself. I should be able to set it up by myself inside my garage.<br><br>Cheers!<br> Ian.<br><br><blockquote style="padding-left: 5px; margin-left: 0px; border-left: #0000ff 2px solid; font-weight: normal; font-style: normal; text-decoration: none; font-size: 10pt; font-family: arial,sans-serif; color: black;">-----Original Message-----

Working alone, it took me 8 hours to build the gantry, lift the sub, and swap out the trailers. No issues however and it all went pretty smoothly. I have to admit I was a bit nervous about lifting the sub on wood beams, but I had used an online calculator (<a target="_blank" href="http://forestryforum.com/members/donp/beamclc_ctrpointload.htm" id="yui_3_16_0_1_1527603558182_7360" class="">http://forestryforum.com/members/donp/beamclc_ctrpointload.htm</a>) </div><div style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7253" dir="ltr">to determine timber sizes and it turned out to be accurate. If there was any deflection in the beams it certainly was not noticeable to the naked eye.</div><div id="yui_3_16_0_1_1527603558182_7368"><br></div><div dir="ltr" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7256">The submarine is completely stripped and is as light as it is ever going to get. I have no idea what the actual weight is but I calculated approximately 2500 pounds based upon the amount of steel in the various parts (main cylinder, heads, conning tower, battery pods, etc). I decided to split that weight between two beams rather than just one so I could use lighter material. Each beam was created from laminating two 2x10x10 full dimensional planks purchased from a local saw mill which provided a full 4x10x10 beam. Posts were created by laminating two 2x6x10 planks together to provide full 4x6x10 material. Lots of bracing here, there, and everywhere. Looks ugly, but is very solid.</div><div dir="ltr" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7256"><br></div><div dir="ltr" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7256">I used two 2-ton "come along" manual winches attached to the fore and aft lifting rings then lifted/lowered equally between the two winches. Once free hanging, the sub did sway a bit since I had to lean on it to get to the winches. This also made me nervous since too much swaying could bring the gantry down but I was easily able to counter and damper the small sway. I probably would not have done this on a windy day.</div><div dir="ltr" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7256"><br></div><div dir="ltr" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;" id="yui_3_16_0_1_1527603558182_7256">The old and new trailers are the same height so I only needed to lift the sub about four inches so that it was free of the c-channel that it rests inside. Then it was simply a matter of pulling the old trailer out from underneath, backing the new trailer underneath with proper placement, then lowering the sub back down. Happy to have the sub on a road worthy trailer now.</div></div><div class="yahoo_quoted" id="yui_3_16_0_1_1527603558182_7238" style="display: block;"><div style="" id="yui_3_16_0_1_1527603558182_7237"><div style="" id="yui_3_16_0_1_1527603558182_7236"><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-size: 16px;"><br></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-size: 16px;">Videos uploaded for your viewing pleasure</div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-size: 16px;"><br></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="font-family: HelveticaNeue, "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-size: 16px;">Episode 3 - Trailer Swap - <a target="_blank" href="https://www.youtube.com/watch?v=FLbbFUlKHkU" id="yui_3_16_0_1_1527603558182_10449" style="background-color: rgb(255, 255, 255); font-family: "times new roman", "new york", times, serif;">https://www.youtube.com/watch?v=FLbbFUlKHkU</a></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr"><br></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr">Episode 2 - More Trailer Mods - <a target="_blank" href="https://www.youtube.com/watch?v=e4d0nzWIgYo" id="yui_3_16_0_1_1527603558182_10530" style="background-color: rgb(255, 255, 255);">https://www.youtube.com/watch?v=e4d0nzWIgYo</a></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr"><br></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr">Episode 1 - Fender Repair - <a target="_blank" href="https://www.youtube.com/watch?v=zh3d5BI1vig" id="yui_3_16_0_1_1527603558182_10626" style="background-color: rgb(255, 255, 255);">https://www.youtube.com/watch?v=zh3d5BI1vig</a></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr"><br></div><div class="y_msg_container" id="yui_3_16_0_1_1527603558182_7265" style="" dir="ltr"><br></div> </div> </div> </div></div></zzzbody></zzzhtml></personal_submersibles@psubs.org></personal_submersibles@psubs.org></blockquote></div></body></html>
