![]() ![]() (POP rivets was the original brand name.) These rivets are easy to install and replace, using a different kind of rivet tool. Blind rivetsĪlso known as “POP” rivets, these are mostly found on the inside of the Airstream. Good teams can put in a perfect rivet every three or four seconds. Then, as a pair, they move to the next rivet without delay. The difference between “too short” and “too long” is less than a second, so the riveters rely on their experience and the tone of the hammering to know exactly when to stop. Hammering too long will flatten the rivet too much, which also lowers its strength and can look cosmetically awful on the exterior. Stopping too early means the rivet won’t fully deform and thus it won’t fill the hole for maximum holding power. Under normal circumstances, this rivet is in place forever, and it seals so tightly to the body panel that sealant is not needed for the rivet to be waterproof. The rivet gun very quickly hammers the rivet, pushing it inward and squashing the tail against the bucking bar, which causes the tail to get shorter and wider. This fills the hole and locks the two pieces of aluminum together very strongly. The inside installer holds a shaped metal tool called a “bucking bar” that is pressed against the tail (or stem) of the rivet. How to buck a rivet-The outside installer holds an air-powered rivet tool, which is sort of a miniature jackhammer that pounds on the mushroom head of the rivet. To install these requires a team of two people working together like dance partners. ![]() This bond will last the life of the Airstream, unless damaged in a collision. These very strong rivets hold two panels together, or fasten a panel to one of the trailer’s internal ribs. They start life as little mushroom-shaped bits of aluminum. Most of the rivets you see on the exterior of your Airstream are “bucked” (solid) rivets. Most of the contestants are lucky to get about half the rivets in correctly even with some practice. At Alumapalooza we have held Rivet Masters contests for several years, where attendees get a quick lesson on how to put in a rivet properly and then compete for the fastest times. Those two people had to practice relentlessly and demonstrate their skill on practice sheets before they had the ability to repeatedly install rivets with speed and precision. In this age of robotic vehicle assembly you might be surprised to learn that each one of those rivets was placed on your Airstream by hand by a pair of skilled workers at the factory in Jackson Center, Ohio. Take those 5,000 rivets away and you’ve got a floppy pile of soft metal. Rivet guns are used in Industrial applications, workshops, and garages.Your Airstream is made of aluminum, but rivets are what make it strong. The faster blows are less intense than the slower blows, making this type of gun more appropriate for rivets made of softer materials. Averaging approximately 2,500 bpm (blows per minute) offering increased control, accuracy and less kick than guns that deliver a single blow.Fast-hitting gun - These operate in a similar way to the slow-hitting versions, but at a higher rate of speed. If you have a large number of rivets to set this is the ideal option, quick and easy and virtually fatigue-free.Slow-hitting gun - For use on hard rivets, slow-hitting rivet guns deliver repeated blows to the rivet as long as the trigger is compressed. This provides a higher amount of force to the rivet reducing the risk of damage and creating uniformity in the positioning and depth of the rivets.Air riveters - are an essential air tool for heavy-duty applications. When the trigger is squeezed, the throttle valve opens, allowing the pressurised air to flow into the piston. ![]() This operation pulls the pinhead then the rivet pin expands, the excess stem breaks off leaving the rivet permanently fixed in position holding the two pieces of material together.How do they work?Pneumatic rivet guns - Regulated air passes through a throttle valve which is typically controlled by a trigger in the handgrip. Our rivet gun range includes leading brands such as Bahco, RS PRO & PREVOST.How are they used?Air rivet guns are powered by an air compressor via an air hose feed, during application a rivet pin should be inserted into the riveter, place the pinhead into the hole of the materials you wish to secure then squeeze the trigger (for a pneumatic riveter one pull of the trigger is usually enough). These guns are known as a pneumatic riveter, pneumatic pop rivet gun or air riveter, used to drive rivet pins. Air Rivet Guns Use an air rivet gun to join & secure materials together. ![]()
