A table saw is a versatile tool that can be used for various woodworking projects. To ensure precise and accurate cuts, it is important to have a properly aligned table saw. However, over time, the alignment of the blade and the fence may be affected due to wear and tear. This can result in inaccurate cuts and compromise the quality of your work. One way to address this issue is by using shims to adjust the alignment of the table saw.

Shims are thin pieces of material that are placed between the table saw’s parts to fill gaps and make adjustments. They can be made from various materials, such as plastic, metal, or wood. Making your own shims allows you to customize their thickness to achieve the precise alignment needed for your specific table saw.

To make shims on a table saw, you will need a piece of material that is slightly larger than the gap you need to fill. Start by measuring the gap between the table saw parts that need adjustment. Then, mark the dimensions on your chosen material. Using a table saw, carefully cut out the shim, keeping in mind the desired thickness. It is important to take your time and ensure a clean and precise cut.

Once the shim is cut, test its fit by placing it between the table saw parts that need adjustment. If it is too thick, use sandpaper or a file to remove a small amount of material until it fits properly. Likewise, if it is too thin, you can layer multiple shims together to achieve the desired thickness. It may take some trial and error to find the perfect fit, but the end result will be a properly aligned table saw that produces accurate cuts.

Remember to always wear protective gear, such as safety glasses and gloves, when working with a table saw. Additionally, regularly check and maintain your table saw to ensure its optimal performance. By making shims on a table saw, you can easily adjust its alignment and continue to produce high-quality woodworking projects.
