The rivet gun that I bought is a 3X rivet gun that I bought from a company called Aircraft Spruce.
The waffle tool I bought from Snyder's.
I use the waffle tool in the rivet gun on most of the rivets, and I use one of the (oval head shaped) rivet sets that came in the box with the gun, on the other (head) side of the rivet.
I hold the oval head rivet set in an old air hammer.

This is a very simple process, but works best if you have a helper.
