Yes , there is more welding involved ( they must have full penetration welds ) . But with the hull on a set of rollers you can do all the welding standing up instead of crawling around on your hands and knees in a cramped space .</div><div>Dan Lance<br clear="none"><div class="yiv2763670281yqt3205357397" id="yiv2763670281yqt92199"><div class="yiv2763670281gmail_extra"><br clear="none"><div class="yiv2763670281gmail_quote">On Sep 7, 2017 2:50 PM, "irox via Personal_Submersibles" <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br clear="none"><blockquote class="yiv2763670281quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi<br clear="none">

keeping the K250 stiffen questions momentum going.<br clear="none">
<br clear="none">
I'm restore-modding a early K250 (more like the last of VAST MK3s sold as a K250 after VAST and Kittredge parted ways). One change I'm considering fitting external stiffeners to replace the internal stiffing/ballast tank structure.<br clear="none">
<br clear="none">
Also, if I was building from scratch I would be making the same consideration.<br clear="none">

Anybody else thinking about this or have thoughts about this?<br clear="none">
