[PSUBS-MAILIST] progress

Brian,Be careful, I always wet the surface then apply matting or you run the risk of not having adhesion.  Hank

   I found another use for my super expensive EPDM adhesive :  Gluing fiberglass cloth onto an upside down surface !   This way I was able to apply the epoxy while it was held up there.    Brian

I'm making some good progress in taking care of those pesky pinhole leaks in some areas on the ferro cement hull.  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 ;-)  Brian_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles
