In order to dimple the last few holes I had to make a new tool and use one from the practice kit. Mike Boardman had given me a bunch of old rivet steps from his time at Cessna and I wasn't going to use one of them so I was able to use my drill press and bore down a hole into it so I could add the male dimple die. This allowed me to insert it into the rivet gun. For the female end I used the steel plate that the practice kit called out to use. Worked pretty slick. You can see the tools in the background of the last two pictures.
Hole driled in an old rivet set to accept the male dimple die.
