Regarding the tramp frame being bonded? Especially in older boats that got a little bit loose from use, some users opted to bond the whole frame together with epoxy, and then place new rivets. (The stiffer the boat, the faster it sails). So you may find the corner frames epoxied to the cross frames, maybe to the side rails, and potentially to the hull posts too. If they are not sloppy, bent, or broken, why remove?
If you are still intent on disassembly, look for the bolts and obvious rivets which can be removed or drilled out. But you typically need one very serious "rivet gun" (the handles may be 2 ft long) to properly set new rivets later.
While I'm not "The expert".. if it's bonded, its most likely epoxy. And most epoxies will soften with heat. But you are also talking about a LARGE heat-sink. If the frame is removable from the hulls, you might be able to disassemble and clean up, and re-assemble. But if the frames are bonded to the hull posts.. you'll likely have a tough job! I'm sure you don't want to get the post too hot. So you may have a real challenge on your hands! Best Wishes.
