The floor in my workshop is uneven and it’s difficult to keep my tool stands and benches from wobbling. So I’ve been using this leveling device for over ten years. It works on almost any size bench or stand. The pivoting leveler attaches to the lower stretcher of your tool stand. (You can install a stretcher if needed.) The leveler automatically adjusts to any unevenness in the floor, resulting in a rock-solid platform for your tool or workbench.
The leveler is made from 3⁄4" plywood and shaped as shown above. Of course, you’ll need to adapt the dimensions to suit your tool stand or workbench. The leveler is mounted to a stretcher with a 1"-dia. dowel, washers, and cotter pin that act as a pivot point. I added a threaded insert and hex bolt on each end of the leveler to prevent it from pivoting if you move the tool. Drilling an oversized hole for the bolt allows the leveler to adjust up to 1⁄4" for an uneven floor. The bolts don’t need to be tightened.
Finally, I added a nylon bumper at each end of the leveler. They also help reduce friction when it comes time to move the tool.
