RIVET GUNS INSTALL

Be sure you get the type of gun you need. If you don't already own a suitable rivet gun and are in the market for one, check around with other builders before you buy. This must be done not only to seal out moisture and corrosion, but also to improve overall appearance. Another disadvantage, pop rivets, being hollow, also introduces the need for sealing each of the holes in the installed rivet heads. Futhermore, pop rivets are more likely to loosen under prolonged vibration. There can be no doubt that such an assembly, riveted together with solid rivets, is more reliable, and generally stronger than one similarly put together with pop rivets.Īlthough pop rivets are easier to install, they are complex to manufacture and, as you might expect, are more expensive to use than the solid type rivets. Properly set, the compressed rivet solidly locks the riveted parts together permanently. Then, as the blows (impacts on the rivet) continue, the shank end of the rivet becomes compressed and flattened, forming what is known as a 'shophead'. The net effect of this coordinated hammering and bucking action causes the rivet to swell, filling its hole tightly. (A solid rivet can also be 'set' with a rivet squeezer.) Then, and only then, the other end - the one with the manufactured head - can be 'driven', or 'set', by impacts from a rivet gun fitted with the correct rivet set, or by the hammering blows of a hand wielded ball peen hammer. To drive (set/upset) a solid rivet after it has been inserted in a rivet hole, the protruding stem (shank end) of the rivet must be backed up or bucked by a 'bucking bar'. A rivet gun, a bucking bar and a rivet set. Furthermore, you will have to become proficient in the use of a few special tools. You do not enjoy the luxury of that pop rivet 'blind' feature because you absolutely must have access to both sides of the parts being riveted. Unfortunately, it's quite different with solid rivets. even if you don't have access to the back side of the parts being riveted together.

For one thing, you can install those hollow-core pop rivets working alone with only a simple hand operated pop riveter. Installing solid rivets in an aircraft structure requires considerably more know-how and skill than does working with pop rivets.
