Hey cycle, I was an aviation metal smith in the Navy, seeing that video brought back a lot of memories. the anvil that the guy on the left is holding has not changed in 50 or 60 years. the rivet gun on the right has changed to a one handed affair. the most important part of the riviet gun in the rivet set, that is the part that presses against the head of the rivet. the set has to have the same dome profile as the dome, or button head, of the rivet or it will flatten the head of the rivet. i would practice a bit before you start on some thing that you care about.
Hope this helps.
Pablo
