Hello friends. To make this drill press drum sander I use a bearing that helps to keep the drum sander always straight. I also show how to rectify and how to true the drum sander to make a perfect cylinder. I also make a drill press table to fit the bearing and to sand the workpieces easily. A woodworking sander, like this drill press sanding attachment, is a woodworking machine that helps a lot when sanding wood in our woodworking shop. And the best part is that woodworking drum sanders are not very complicated to make.
