<div dir="ltr"><div>Thanks Brian - I was really unclear as to what I was asking, but that actually helped because you explained some things I wasn't expecting. So what I thought were fiberglass pressure tanks are foam filled? I assumed they were ballast tanks and you filled them water to control buoyancy, hence the reason I assumed they were pressure tanks and hence the reason I was asking if you made them or not. :D</div><div>But what I was trying to ask was how deep is your sub rated to dive to?</div><div>This has been interesting and a lot of fun - thanks for taking the time out to explain what you're doing.</div><div>Ian</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 14, 2020 at 7:11 PM Brian Cox 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 style="font-family:Arial,sans-serif;font-size:10pt"><font size="2"><font face="Arial, sans-serif">Ian, That foam is rated to 580psi, but it needs to be sealed or it will absorb water . Yes I made those foam pieces, the tube was easy because I just used 12" pvc pipe and then I had to make end pieces for them. The odd shaped piece I ended up making a mold using thin luan plywood and one bys, and then I put packing tape all over the inside of the mold so the foam would not stick, and put a thin coat of Vaseline over the packing tape. I had to do some additional shaping to avoid protrusions and so I could slide it in there. </font></font><div><font size="2"><font face="Arial, sans-serif"><br></font></font></div><div><font size="2"><font face="Arial, sans-serif">It's a two part foam, you have 60 seconds to pour it after you mix it thoroughly until it starts foaming. </font></font></div><div><font size="2"><font face="Arial, sans-serif"><br></font></font></div><div><font size="2"><font face="Arial, sans-serif">Brian</font></font></div><div><font size="2"><font face="Arial, sans-serif"><br></font></font></div><div><font size="2"><font face="Arial, sans-serif"> </font></font><br><br><span style="font-family:Arial,sans-serif;font-size:10pt">--- <a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a> wrote:</span><br><br><span style="font-family:Arial,sans-serif;font-size:10pt">From: Ian Juby via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span><br><span style="font-family:Arial,sans-serif;font-size:10pt">To: Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span><br><span style="font-family:Arial,sans-serif;font-size:10pt">Subject: Re: [PSUBS-MAILIST] Mo buoyancy</span><br><span style="font-family:Arial,sans-serif;font-size:10pt">Date: Tue, 14 Apr 2020 18:56:35 -0400</span><br><br><div dir="ltr" style="font-family:Arial,sans-serif;font-size:10pt"><div>NOICE.
