The Essential Guide to Bucking Bars for Aircraft Maintenance

Bucking bars are essential tools for aircraft maintenance, but they can be confusing to use. This guide breaks down everything you need to know about bucking bars.


If you work in aircraft maintenance, you're likely familiar with bucking bars. These tools are essential for riveting and shaping metal, but they can be confusing to use if you're not familiar with them. In this guide, we'll break down everything you need to know about bucking bars, including their different types, sizes, and uses.


What are bucking bars and why are they important?

Bucking bars are heavy, solid metal bars used in aircraft maintenance to support the back of a rivet while the front is being hammered into place. They are important because they prevent the rivet from deforming or buckling under the force of the hammer, ensuring a secure and tight fit. Without bucking bars, riveting would be much more difficult and time-consuming, and the structural integrity of the aircraft could be compromised.


Types of bucking bars and their uses.

There are several types of bucking bars available, each with its own unique shape and size. The most common types include straight, offset, and corner bucking bars. Straight bucking bars are the most versatile and can be used for a wide range of riveting tasks. Offset bucking bars are designed to reach into tight spaces, while corner bucking bars are used for riveting in corners and other hard-to-reach areas. It’s important to choose the right type of bucking bar for the job to ensure a secure and tight fit.


How to choose the right bucking bar for the job.

Choosing the right bucking bar for the job is crucial for ensuring a secure and tight fit. Consider the size and shape of the rivet, as well as the location of the riveting task. Straight bucking bars are the most versatile and can be used for a wide range of riveting tasks, while offset bucking bars are designed to reach into tight spaces. Corner bucking bars are ideal for riveting in corners and other hard-to-reach areas. It’s also important to consider the weight and material of the bucking bar, as heavier bars can provide more force but may be more difficult to handle.


Proper technique for using a bucking bar.

Using a bucking bar requires proper technique to ensure a secure and tight fit. First, hold the bucking bar against the rivet head with your non-dominant hand. Then, use a rivet gun with your dominant hand to drive the rivet into place. As the rivet is being driven, use the bucking bar to apply pressure to the tail end of the rivet. This pressure helps to deform the rivet and create a tight fit. It’s important to use consistent pressure and to avoid hitting the bucking bar too hard, as this can damage the rivet or the surrounding material. Practice and experience are key to mastering the proper technique for using a bucking bar.


Safety tips for using bucking bars.

When using bucking bars for aircraft maintenance, safety should always be a top priority. Make sure to wear appropriate personal protective equipment, including safety glasses and gloves. Always inspect the bucking bar and rivet gun before use to ensure they are in good condition and free from defects. Use caution when working in tight spaces or awkward positions, and be aware of any potential hazards in the surrounding area. Finally, never use a bucking bar as a hammer or for any purpose other than its intended use in aircraft maintenance.
