I recently started making these rivet jigs for personal use and for friends. They seem to be popular so I am adding them to the products my small machine shop makes.  They help you make copper rivets out of #6 bare copper electrical wire. Using a ball peen hammer you can make flat head or dimpled head styles. Dome head rivets can be made using a normal rivet setting tool.  My website is http://heromount.com...pper-rivet-jig/
