Rowland,
I gotta ask - what's your technique for making the holes in the vee BELOW
the hinge holes bigger than the hinge holes????
In reality 1/8" works just fine - it's just the break-head that enters the
hole in the vee, and that doesn=92t swell in diameter. Also it pulls clear of
the hole very quickly.
Regards,
Jeremy

Andrew - drill the holes. Better make them a bit larger than 1/8" as
the first thing that happens as you start to pull the rivet is that
the shank swells at the tail end. You don't want that bulge to seize
in the hole and pull out a patch of layup with it as you squeeze
further. Afterwards you can fill the holes with flox if you wish, but
there's not much room for manoeuvre in there even after pulling the
rivets.
Don't try to push the rivet heads down as you snap them, because it's
highly likely you won't manage it successfully. If the heads aren't
down tight onto the countersink you made, then they aren't providing
adequate holding strength & location for the hinges, and that's much
worse news than any cosmetic shortcomings!
regards
Rowland
