Thicknesses ("grip range"), and with different diameters of rivet body (usually 1/8th inch, or 3/16ths inch),Īnd with different thicknesses of mandrel (smaller on the 1/8th inch wide rivet than the 3/16ths inch), and with wide-or-normal flanges.įor some applications you might want a shorter rivet body (Coinbank, Spinner) and others a longer one (Pinwheels). You can buy rivets that have varying lengths of rivet bodies for gripping materials together of different You can find more detail in this Youtube video. If you continue to squeeze harder, you'll pop off the mandrel. You want to leave the mandrel in place, so stop squeezing the rivet gun as soon as you feel a change in the resistance. The expanded rivet body tube is larger than the hole in your target, so it's locked in place.įor some of my designs (the Pinwheel, the generic Cannon, the Spinner), When the rivet head meets up to target, the pressure increases until the mandrel snaps off inside the flange. This pulls the rivet head through the rivet body tube, which expands it. Then you you squeeze the handles of the rivet gun, which causes it to grab onto the mandrel and pull it back hard. Then you stick the rivet body through the holes in the target until the flange rests flush against the target. Then you stick the rivet's mandrel completely into the rivet gun. To use it, you first make correctly-sized holes in the two things you want to rivet together (the "target" material).
