#Ak rivet sizes how to
Okay – enough background – let’s talk about how to size these things – riveters are are sized based on the stroke length of the piston and an arcane naming scheme like “2X”, “3X” and “4X”. Traditionally with air hammers we think about driving apart exhaust pipes, cutting open barrels and what not. When you are building an airplane you need precision and you sure don’t want the riveter to slip and mar the aluminum. When guys gush about how well they can control a big riveter, pay close attention because they aren’t kidding. This allows you to really dial in the speed and strength of the blows. With air riveters, the main thing you get is a variable flow trigger, sometimes called a “tickle trigger” and usually a built in air regulator. However, as you will read here, there are air hammers that do overlap with air riveters. If you see a tool with virtually no controls, it is likely an air hammer. What usually, but not always, differentiates the two is the degree of control you have with the trigger and an integral air regulator to adjust the BPM and how hard the blows are. Thus they are delivered from the hundreds to almost three thousand blows per minute (BPM). Air hammers and air riveters are remarkably similar – a pneumatic (air powered) pistol is going down a bore and slamming into the end of the unit where a tool is attached. I am going to throw two terms around in this post that I need to explain. You know what, it surprisingly works well and now I only use my press on the removal of really stubborn barrels. For years I used my 20 ton press to remove and install barrels on AK rifles and then somone, Gunplumber maybe, told me to try using an air riveter instead.
