Dimpling Block - Setting Perfect AN426 Rivets

I have had several questions on the earlier explaination of making a dimpling block to set AN426 rivets. A couple of photos have been added to this link to show what the dimpling block looks like and how it is used to set near perfect rivets. This process will set the rivet in the skin before actually driving the rivet. The result is that the rivet and skins will fit nicely together. When the rivet is actually driven this will produce the best quality flush rivet.
