I started my project with mainly used/borrowed tools from a friend and have been adding tools of my own as I go along. The dimple dies I was using were giving good results but they have built a whole airplane already and I figured why not get a new set of my own. I bought the Cleveland spring back dies to use on the skins. I also bought a set of the sub structure dies just to try it out. I tried on a scrap before going to town and everything appeared to look good. I went ahead and dimpled real parts and during assembly I started noticing a slight gap around the manufactured head of the rivets that I wasn't getting before with the old dies. I was pretty concerned so I took some scrap, made a test part, and took a cross section of the joint on a wire EDM machine I have at work. I think the joint looks OK (other than the shop head being a little off) but you can see the little gaps around the head. It looks like the new dies leave a larger radius and is the reason for the gap.
What is everyones thoughts on the gaps I am seeing? Could there be a different reason this is happening?
