I used this item to level out the blades on my jointer. It'll do the job, but first make sure your base is level. I have a bench jointer and the outfeed base is not perfectly level. Both the infeed and outfeed bases are aluminum stock and there is enough flex in them to cause them to bow a bit between the four bolts that hold them down. No fault of this dial indicator. The jointer just has too-thin aluminum bases. However, I have to move the base of this dial indicator back and forth on the outfeed base to zero out the blades. Have to account for the base's unevenness. It gets four stars as there is no way to zero out the indicator itself. Instead, you use the fine adjustment screw on the arm to zero out. Kind of inconvenient and dumb.
