My wife and I are cleaning/resealing the skylight in our Scamp
and running into a rivet problem: we're not sure how to remove the rest of the rivet after the rivet head has been removed. As you'll see in these photos, the rivets that held the skylight bracket in place apparently only go through the fiberglass, not the insulation (I forget what that spongy stuff is called), so I have no way of just pulling it through.
just put rivets in other locations in the skylight mounting bracket, but A) that's more of a hassle, especially since I would have to drill all-new holes in the bracket (using a drill bit limiter), and
that's leaving a lot more entry points for water (note that we're going to be sealing this whole thing with butyl tape once we get the rivet situation sorted out). I'd prefer to remove the rivets and put new ones in the same place if possible.
There are other rivets shown that are for the aluminum finishing brackets, those are less of a problem (though I haven't yet figured out how to pull those through either, even though I have access to both ends of the shaft).
