![]() ![]() Occasionally, you’ll need to reverse the procedure and remove the rivet. As involved as that sounds, the whole procedure takes less than a couple of seconds. The mandrel then breaks off at a predetermined weak spot, leaving the rivet flush with the surface of the material. As the mandrel is withdrawn, it causes the tube to swell, locking the two pieces together. The rivet is inserted into the hole and, using a rivet gun the mandrel is withdrawn through the tube. How to Install a Pop RivetĪfter the two sections to be riveted are aligned, a hole that’s the diameter of the rivet is drilled through the layers to be joined. Made of a soft metal, usually aluminum or copper, a pop rivet consists of a small nail, called a mandrel, inserted into a tube. Around the house, they are most typically used to join sections of gutters and downspout fittings. Pop rivets are used to join two pieces of thin material, such as plastic or aluminum, from one side, eliminating the need to access the back of the workpiece. (“Pop rivet” is actually a genericized term for the Stanley Engineered Fastening’s POP brand rivets.) These days, the rivet you will most likely encounter is a smaller, lighter-duty version called a blind or “pop” rivet. While one worker applied pressure to the head, another worker then peened over the tail protruding from the steel with a manual or pneumatic hammer. These rivets were thick iron plugs with mushroom-shaped heads that were heated until they were red-hot and placed into holes in the steel. Before the widespread use of the structural bolt, rivets were used to join steel plates that became bridges, skyscrapers, tanks, airplanes, and ships. I simply use the bit to route out the head, and when that pops off (sometimes you might want to use a sharp chisel to carefully shave the head if it’s being stubborn), I make sure to be centered and drill out the old rivet body.If you hear the word “rivet” and immediately think of an industrious woman named Rosie, your point of reference would be sometime in the last century. ![]() ![]() That is so the looks do not basically change and the strength of the shank was maximized, so as to be similair to the buck rivets shan strength.įor what it’s worth, I have just been using 1/8″ and 5/32″ drill bits to remove rivets and to install rivets. ![]() Olympic rivets for Airstream usage have always been 5/32 shank, but with the same size “brazier head” as the 1/8 buck rivets. The best drill bit size to use is a #21, since a hole will not be perfectly round, unless using a drill press. #30 = 1/8” (which is the shank size of the rivets used most extensively in assembling the interior of an Airstream)įor removing Olympic rivets, Andy from Inland RV says:Īn Olympic rivet is 5/32 which is. 159 thus the #21 drill bit gives a 5/32″ rivet a little clearance to slide into the hole. Sometimes you will see/hear people using a number instead of a size (inches or millimeters) for a drill bit.ĥ/32″ is. Vista vue window clecoed in place Removing Rivets There are two types of blind rivets, often referred to as “Olympic” and “pop” rivets. So if you are fastening something to another surface without being able to see the back (like skins or trim), you would use a blind rivet. The 5/32″ rivets actually hold the Airstream together (panels and ribs).īlind rivets get their name because you can install them in situations where you can’t see both sides of the surface being riveted (there is a blind side). Airstreams use only two sizes: 1/8″ and 5/32.” The 1/8″ rivets are generally used for trim on the exterior, and to hold the skins to the ribs on the interior. There are two types of rivets on an Airstream: bucked rivets and blind rivets. But don’t worry, they are easy to drill out if you need to change something you’ve riveted. Rivets are more “permanent” in that they stay put. Screws will back out of their holes with the constant road vibration that an Airstream experiences, so eventually a screw will no longer be holding whatever it was screwed into. You “buck” a solid rivet.įirst of all, there really shouldn’t be any screws on an Airstream. Here is some basic information to get you started. If you’re going to work on an Airstream, you have to know about rivets. ![]()
