Does anyone know of a source for an air rivet hammer that only strikes one
blow per trigger pull? I have used some old ones and liked them better than
a standard chatter gun.

Dunno if any current suppliers are making them, but you could check
with The Yard Aircraft Tools.

Google.

A good rivet gun will be easy to control the hits and should have a
regulator on it to set the air flow going into the gun. Most of the
riveting I did was with a 4x gun. This is a little overkill for 3/32
rivets but I could set up to a 3/16 an470 with no problem. If you
don't hit the rivets hard enough they will get work hardened before they
are completely set which happens when you are using an undersized gun.

how can you tell if they work harden????

They will get hairline cracks in them and will not completely set.

They don't expand properly. The rivet should expand to 1.5 times the
stem diameter when it is properly set.



Here is a good site on rivets and riveting

They don't say anything about 'happy rivets'

They crumble or shear when they are struck.
