Posts: 21 | I epoxied the frame of my H16 last year with West Marine epoxy, and now I need to take it apart so I can take it to Costa Rica. I have a fourty foot shipping container to put it in, but the only way I can make room for it is if it's taken apart!!! Has anyone ever done this before? Will a heat gun melt the epoxy?... before melting the aluminium, let alone the fiberglass? Is there another way, like drilling out all the rivets and using a hydrolic jack to pry it apart??? It's getting down to the wire if I'm going to take it with me, which I really want too. So any help or advise anyone can give me will be greatly appreciated. Thanks, andrew | | | Re: Taking apart an epoxied frame???

Posts: 349 Fort Loramie, Ohio | Hello, I haven't done this myself, but I've heard it discussed. Heat is the only way to go to get the epoxy to release. I would keep cool rags around the bottom of the pylons during the process to limit the heats exposure into the hull. It might take some time for the heat to makes it's way through the casting, but it should work. Maybe you would be better off giving a buddy some cash to borrow his hulls and frame for the race?

Posts: 493 Minnesota | So far, it sounds like no one has actually tried using heat to burn the epoxy. First hand knowledge is best for something like this. I'd be REAL wary of trying heat. The aluminium is going to conduct the heat pretty darn fast. There is foam inside the pylons that will get damaged. I suppose you could replace it. But, what if the heat gets down into the hull, -will it melt or burn the hull's polyester or the foam core? Also, I believe that epoxy is thermosetting,... if so, then it will not melt, but would only burn. I would not recommend trying this on a good hull. It would be interesting to experiment on useless hull that's trash anyway.

It is soft and squeezable. It is put in as a plug to keep the water out, when you turn your Hobie into a submarine. The front foam plug has a very small metal tube through the foam to vent air from inside the hull. If you have melted the foam, you may find that you are taking in more water than normal, when you bury the hull.
