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.
As much as I’d like to provide a book with everything you’ll ever need to know about woodworking (as if I even know all that!), it’s just not possible. Chapter 21 is my way of helping you to keep exploring this immense craft by providing you with a bunch of resources. This chapter contains contact info for woodworking magazines, addresses for helpful Web sites, and ideas to help you keep expanding your knowledge and skills.
I prefer the large size because it will cut the most sizes. Years ago I purchased a medium shoulder plane, but it didn’t cut the larger sized joints, so I sold it and purchased a large shoulder plane so I could cut and trim most sized joints. Most of your traditional woodworking hand tools can be vintage/used, but used shoulder planes can be very hard to rehab and get “square”, so I recommend spending the extra money on a new shoulder plane. See my recommendations in my hand plane buying guide.
Drill four 5/8-in.-dia. 1/2-in.-deep holes on the large disc?inside the traced circle?then use 5/8-in. dowel centers to transfer the hole locations to the underside of the small disc. Drill four 1/2-in.-deep holes on the underside of the small disc and a 1/2-in.-deep hole in the center of the top for the dowel handle. Glue in the dowels to join the discs, and glue in the handle. We drilled a wood ball for a handle knob, but a screw-on ceramic knob also provides a comfortable, attractive grip.
The very affordable coping saw (often around $20) is regularly used for rough cutting shapes in the board, but especially for removing waste from dovetail joints (one of the most common wood joints). An affordable coping saw will work just fine as long as you have plenty of replacement blades on hand (also very affordable). Read my hand saw buying guide for more detail on brands & features to look for when purchasing a coping saw.
