Sanding the inside of a hole or curved surface can be difficult. To simplify that task, insert a 1/4 x 3-in. bolt into the pilot hole of a hole-saw cutout. Secure the bolt with a washer and nut. Using a hacksaw, cut a 1/4-in. deep slot in line with the bolt. Cut a piece of adhesive-backed sandpaper so that you can slide one end into the slot, wrap it around the cutout, and slide the other end back into the slot. Chuck the bolt into a drill, and you now have a homemade drum sander. — E.R. Comstock. How to Sand Wood Faster
Pocket screws create a solid, simple-to-make joint. Because of the size and visibility of the hole, it’s usually located in areas that are concealed or rarely seen (though special plugs can be used to fill the holes.) Craig Sommerfeld, founder of The Kreg Tool Company, is credited with popularizing pocket screw joinery in the 1980s. The company today is the leader in creating the jigs, clamps and screws used to create pocket screw joints. Learn how to use a pocket screw jig in woodworking projects.
With a pencil and a protractor, divide the larger disc into 30-degree wedges to create 12 center lines for the bottle indents. Center and trace the smaller disc on top of the larger disc. Next, with a drill press, drill 3/8-in.-deep holes on the 12 center lines with the 1-7/8-in. Forstner bit, spacing them between the disc’s outer edge and the traced circle. Next, divide the smaller disc into 60-degree wedges and drill six more 3/8-in.-deep holes with the Forstner bit.
