Every worthy project deserves the privilege of getting a new tool to get the job done. In this case I have an old work chair that needed to be refurbished and refurbished. The sander works great, the 1/4 size sandpaper sheets attach easily to the base, and the hole punch tool comes with a few initial sheets of sandpaper. The hole punch allows you to use regular 1/4 sheet non-perforated self-tapping sandpaper with the dust bag attached. The device is compact, well balanced and easy to use. The on/off switch is a bit stiff, but that's not a problem. I would recommend that you periodically remove the steel backed rubber floor panel to keep the vacuum holes invisible. You will need a tiny sprocket to loosen the 8 bolts holding it in place. This is a 5 minute task. I recommend.
