Sorry Ken for the lack of clarity there. I had one of the "Back Riveting Bars" (see links below) on the table but forgot to talk about it directly. The pitfall of being non-scripted I guess. For back riveting with a bar rather than a plate, you want to use the heaviest bar possible and cover a large area of the skin with it. That is why we sell the bar that looks like the giant flush set. It gives plenty of mass so the rivet does not sit at all high, and plenty of surface area so the bar will not make a dent in the material (since it is heavy). For this I would not use the tungsten bar since the surface area is less, but you may find that holding it with the large surface on the skin would work?? Can always try it on some scrap, or on your buddies project.
