As a Flight-line mechanic for Boeing many years ago, I'll tell you how we
were trained to take out rivets. Tools needed, spring loaded center punch,
a set of flat punches and your drills. Center punch the rivet head, drill
the rivet head but not all the way to the hole. Use the proper size flat
punch in the drilled rivet head and snap the rivet head off. Then use a
flat punch smaller than the hole and punch out the rivet shank. 9 times out
of 10 you can use the same size rivet you punched out.
