<DIV style="font-family:Arial, sans-serif; font-size:10pt;"><DIV>Hank,</DIV><DIV> I've done a lot of fiberglass and resin both polyester and epoxy, making surfboards and such, the resin will go right thru the glass no problem. I would like to see how you could make glass stick upside down, especially if it was coated first. Trying to do that even if the surface is right side up would be problematic. With an already wet surface you run the risk of not being able to place the fiberglass perfectly flat, one minor screw up and you would have a wrinkled gooey mess on your hands. Ideally working on a right side up surface would be the best, but short of that I think my glue method worked pretty darn good, I may have to even make a youtube instructional video !! </DIV><DIV> </DIV><DIV>Brian<BR><BR>--- personal_submersibles@psubs.org wrote:<BR><BR>From: hank pronk via Personal_Submersibles <personal_submersibles@psubs.org><BR>To: Personal Submersibles General Discussion <personal_submersibles@psubs.org><BR>Subject: Re: [PSUBS-MAILIST] progress<BR>Date: Thu, 28 Apr 2016 20:39:02 +0000 (UTC)<BR><BR></DIV><DIV style="color: rgb(0, 0, 0); font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255);"><DIV><SPAN>Brian,</SPAN></DIV><DIV><SPAN>Be careful, I always wet the surface then apply matting or you run the risk of not having adhesion. </SPAN></DIV><DIV><SPAN>Hank</SPAN></DIV> <DIV><BR><BR></DIV><DIV style="display: block;"> <DIV style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <DIV style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <DIV dir="ltr"><FONT face="Arial" size="2"> On Thursday, April 28, 2016 2:10 PM, Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<BR></FONT></DIV> <BR><BR> <DIV><DIV><DIV><DIV style="font-family: Arial, sans-serif; font-size: 10pt;"><DIV> I found another use for my super expensive EPDM adhesive : Gluing fiberglass cloth onto an upside down surface !

I filled the really bad one hydraulically with cement, the 3M 5200 is a bit too viscous for the pinhole leaks even with a vacuum going on the hull. Everything is pretty closed up now. Finally, I'm doing fiberglass and epoxy resin over the whole area that has been giving me trouble. I think on my next sub I'll construct a giant rotational single axial machine so I can make sure all the voids get filled. Also, as I've use a lot of fiberglass and epoxy here and there I'm coming to the realization that encapsulating the entire ferro hull with fiberglass and epoxy would be beneficial. Although, the ferro cement sailboat book I followed to construct my hull, did not recommend it ( but they weren't building a sub). Getting ready to start concentrating on lead ! I'll probably have to add another axel to my trailer because of the extra weight ;-) </DIV><DIV> </DIV><DIV>Brian</DIV></DIV></DIV>_______________________________________________
