This worked, after a fashion. With a bit of practice the dimples
started looking right. I set the rivets in the same manner: Set
countersunk rivet into the dimpled hole, flipped the work upside down
and held the rivet against a bucking bar clamped in the vice. Then I
used the hammer to squash the rivet until it was flattened about the
proper amount. Needless to say, these weren't structural parts I was
building.

OTOH, a friend of mine built an entire T-18 this way. The airplane has been
flying for almost 30 years....
