knock out mandrels, here's what I do. I just take an
old mandrel stem from a pulled rivet, snip it to about
1/2 inch long, and hold it in a vise grip wrench with
about 1/8 inch sticking out one end. Then simply stick
that in your rivet mandrel hole and tap the other end
with a hammer, and it's done.
The one problem I haven't figured out, though, is how
do you prevent unwanted dimpling of skin on the head
side when the mandrel is in real tight with epoxy and
you can't get at the backside of the rivet to support
it.

Guess we didn't offer enough detail... I
just supposed that everyone knew we
only intended our list of tools to be used
to knock out the mandrel, then
drill the head of and remove the rest of the
rivet as you described below.
But you've certainly covered it beyond question now.
