Using the cross peen side of the riveting hammer lightly tap the end of the wire to start to spread the metal just like you would when making a wire rivet. Keep going lightly, turning the clamp to evenly spread the wire, use the round flat end of the hammer to make a rounded head shape. Keep pulling a little bit more wire out when you have spread the end flat against the drilled hole. I pulled more wire out 3 times. If you hit the wire too hard or you have too much wire sticking out it will just bend over. The wedge end of the clamp needs to be tightly pushed in to stop the wire disappearing as you hit it. This method makes a small flat end for small beads and crystals.
