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

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

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.

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
