pop rivets

[Richard Iddon <riddon@btinternet.com>]

Just a quick question.  Is there a secret to making pop rivets fit the
holes?  I cafefully drill my holes with a pillar drill and with the work
clamped in a drill clamp but the rivets always seem too big for the holes.
The temptation is to use a hand drill and waggle it about a bit to open up
the holes slightly but I'm sure this isn't good practice.

Any suggestions?
