How Wide Should Your Edging Strip Be for 45-Degree Beveled Edging?359

When edging a panel with a 45-degree bevel, the width of the edging strip you need depends on the thickness of the panel and the desired overhang of the edging strip. Here's a guide to help you determine the correct width:

1. Calculate the Panel Thickness

Measure the thickness of the panel you want to edge. This measurement will be referred to as "T" in the following calculations. Note that some panels, such as plywood, may have variations in thickness, so it's recommended to measure in several places and use the average value for more accurate results.

2. Determine the Edging Strip Overhang

Decide how much you want the edging strip to overhang the edge of the panel. This is a matter of personal preference and can range from zero (flush with the edge) to several millimeters. Let's call this desired overhang "O."

3. Calculate the Edging Strip Width

Use the following formula to calculate the width of the edging strip:
```
Edging Strip Width = Panel Thickness (T) + 2 * Edging Strip Overhang (O)
```

For example, if your panel is 18mm thick and you want a 2mm overhang, the edging strip width would be:

Edging Strip Width = 18mm + 2 * 2mm = 22mm

4. Rounding Up

Edging strips are typically available in standardized widths, so it's advisable to round up your calculated width to the nearest standard size. For instance, if your calculation results in a width of 21.5mm, it's recommended to choose a 22mm edging strip.

Additional Considerations:

- If you're using a solid wood edging strip, you may need to account for shrinkage and expansion due to changes in humidity. It's advisable to leave a slight gap (typically 1-2mm) between the edging strip and the panel to accommodate this movement.

- For aesthetic purposes, you can choose an edging strip that is wider than calculated and trim the excess after applying it. However, ensure the overhang is not excessive, as this can compromise the durability of the edging.

By following these guidelines, you can accurately determine the appropriate width for your 45-degree bevel edging strip, ensuring optimal results and a visually pleasing finish.
