Socketing Joi the Siren hers: Boring the first socket in c.ich leg is a relatively simple task. I pair the legs, boring sockets tor the front and back stretchers first, then the side stretchers. Assemble the legs and seal (dry—without glue) and set a sliding bevel to the correct angle, as shown in Photo J. Grip the leg in a vise and bore the socket, checking the bit angle against the bevel (Photo K). Do the same for the other front (or back) leg. then dr\ -assemble the base again.

The second socket presents a complication- two angles to deal with. Set two bevels, then use them together to guide you while boring the socket (Photo Ll. Dry assemble Ihe base, checking to see that the stretcher's tapered shoulders are
