Edge Banding Bottom Trimming Methods174

Edge banding is a process of applying a strip of material to the exposed edges of wood panels, such as plywood or particleboard. This not only enhances the aesthetic appeal of the furniture but also protects the edges from damage and moisture. One of the critical steps in edge banding is the trimming of the bottom edge of the banding material. This ensures a clean and professional finish.

There are several methods for running the bottom edge of edge banding, each with its advantages and disadvantages. Here are some of the most common methods:

Flush Trimming

In flush trimming, the bottom edge of the banding is cut flush with the surface of the panel. This creates a seamless and elegant look, which is ideal for modern and contemporary furniture designs. Flush trimming can be done manually using a sharp knife or a power tool such as a flush trim router. However, it requires a high level of precision and skill to achieve a perfect finish.

Under Trimming

Under trimming involves cutting the bottom edge of the banding slightly below the surface of the panel. This creates a small gap between the banding and the panel, which can be filled with a suitable sealant or adhesive. Under trimming is less demanding than flush trimming, making it a more accessible option for beginners or for projects with less critical tolerances. It also provides a more forgiving finish, as minor imperfections are less noticeable.

Over Trimming

Over trimming is the opposite of under trimming, where the bottom edge of the banding is cut slightly above the surface of the panel. This method creates a small overhang, which can be used to hide any imperfections in the edge of the panel. Over trimming is not as common as flush or under trimming, but it can be effective in specific applications.

Beveling

Beveling involves cutting the bottom edge of the banding at an angle, creating a chamfered edge. This technique can add a decorative touch to the furniture and also reduce the risk of chipping or damage to the edge. Beveling is often used on thicker edge banding materials and can be done using a power tool or manually with a sharp knife and sanding block.

Radius Trimming

Radius trimming creates a curved edge on the bottom of the banding, which can add a unique and stylish look to furniture. It is often used on curved or rounded panels and can be done using a specialized radius trimming router bit. Radius trimming requires a high level of skill and specialized equipment.

The choice of bottom trimming method depends on several factors, including the desired aesthetic appeal, the thickness and type of edge banding material, and the skill level of the operator. By carefully selecting and executing the appropriate trimming method, furniture makers can achieve a professional and durable finish that enhances the overall quality and appearance of their furniture.
