<div dir="ltr">Hi Hank,<div><br></div><div>May I suggest speaking to Mike Caudle? He has two acrylic cylinder CTs, complete with hatches and all, that are beauties but I believe much lower displacement than the one on your project sub, and very lightweight because they are aluminum. If you can arrange a swap or something, one of those might be just what you need.</div><div><br></div><div>Best,</div><div>Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 28, 2020 at 9:17 AM hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:13px"><div dir="ltr">Hi All, I am have some real trouble with my DW style sub mods. If you recall it has an acrylic cylinder CT and a K350 hatch. My problem is, the sub lacks volume to support the heavy hatch\land assembly. I do plan to increase the volume by installing a larger diameter leg tube. This volume increase is still not enough to give me enough buoyancy for stability during transition from surface to being submerged. Options are to loose the cylinder and go with dome. Make a lightweight hatch with GRP, or come up with a creative MBT that maintains buoyancy longer during submerging. </div><div dir="ltr">Hank</div></div></div>_______________________________________________<br>
