Yea the replacement hinge pin as the original, was, is riveted in.
Shade tree version.. need to support the bottom, say have 2 punches,
to expand the hollow rivet ends, put 1 in a bench vise,
then hold the bike's hinge over it. [ probably need helpers on that]
and with the 2nd punch, and a hammer, you will be expanding both rivets at once.
if you have resources, a big Pole or C clamp's jaws could be modified
by a welding shop,
to have pointed punch tips ground out of steel rod, then welded
to the jaws.
perhaps just a bit more rivet head 'upsetting' will tighten up
the existing hinge pin..
