Shimming is basically the the task of placing your gears at such a distance from each other that they will perform at their best. What we airsofters call shims are in many ways more like little washers that go on the axles of each gear. | | Shimming is the practice of using small spacers (shims) to precisely align the gears in an AEG gearbox so that they operate smoothly. A poorly shimmed gearbox often results in a loud whining noise while firing, premature parts wear, stress on the motor, a reduced rate of fire, and poor battery life. | | The goal is to have the gears so that DO NOT bounce meaning to go up and down, or bind meaning that they are being pressed against each other and creating frictions. | | The goal is to space the gears in such a way that maximizes contact between the teeth on each gear while minimizing the amount of space that the gears have to move side-to-side within the gearbox. It is also extremely important that the gears are not shimmed excessively, which would cause them to bind up with one another or the gearbox itself. | | | The teeth of each gear also have to make good contact with each other if the teeth have only a small area of contact then that will put alot of pressure on that small area and cause the teeth to fail over time. | | | So you can imagine good shimming is one of the most important thing when it comes to having a long lasting and reliable AEG. | | | Plus you can make jaws drop when you go to a chrono station and the guys working there shoot your AEG for the first time because your AEG sounds that good. | | Proper shimming is essential for any AEG, and can make a huge difference in performance. Even expensive guns with high-quality internals will feel cheap and sluggish if they are not shimmed well. Likewise, inexpensive guns can perform surprisingly well after a good shim job. It is one of the cheapest, yet most beneficial modifications that can be done to an AEG, and this guide will teach you how to do it. |
