Turn your drill press into a drum sander by making your own spindles to hold sandpaper. This easy afternoon workshop project is great for sanding inside a concave curve, a difficult task for belt or random orbital sanders.
Spin two nuts onto the bolt, tightening them against each other. Then chuck the bolt into the drill and hold a hacksaw blade against the spinning bolt. The nuts help to steady the blade and clean off burrs when you unscrew them.
