Bar clamps are handy when you have pieces on top of each other. A bar clamp or an F-clamp helps secure a project with the table; otherwise, you can use your working surface to hold the projects securely. Moreover, it creates less movement and also much more stability. If you are using a bar clamp, first consider the clamps' material and the project's material. Then you will have it on the corner so that it is easy to set up the device, and you will have to move the bar clockwise to tighten it and hold it in place. However, we recommend using scrap wood or metal pieces as a buffer between the workpiece and the clamp. It protects the workpiece and allows the bar clamp to distribute pressure on the project evenly.
