ESSENTIALS

Advanced Joinery

In Chapter 3 of this series we discussed basic joinery on the table saw, including miters, bevels, rabbets, dados and grooves. In this chapter we're going to take those concepts a step further. Essentially we'll be using the same techniques. These joints simply require a little more thought before you begin. We'll be looking at compound miters, tenons, dovetails, lock joints and splines.

Each of these joints can be created using tools other than the table saw. Some might even argue that they can be made more easily on other tools. For example, compound miters can be easily created using a miter saw. Tenons, dovetails (with the help of a jig), lock joints

PRO TIP:

1-2-3 Crown

When adding crown moulding to a cabinet, start by cutting the compound miter on one end of the front piece, then allow plenty of length and rough cut the other end a bit long. Then cut the appropriate compound angle on both short return pieces for the sides, again leaving plenty of length to the back of the cabinet. Use one return moulding to align the front moulding (forming the complete compound miter), then mark the exact location of the second miter cut on the front piece. Attach the front moulding, then simply mark the square cut on the back of each return, make the cuts and attach.

and splines can be handily created using a router or a router table.

But why buy extra machinery, tools and jigs if you don't have to? All of these joints can be easily achieved with your best friend, the table saw.

Compound Miters

To start we'll take a look at compound miters on the table saw. While regular miter joints are a mainstay in picture framing, if you want to make a more complicated, three-dimensional frame

you need to cut a compound miter. Useful for much more than picture framing, the compound miter joint is probably most commonly used in forming corners for crown moulding. This joint can be accurately created on the table saw with just a little help from mathematics.

To cut a compound miter on a table saw you need to both tilt the blade and angle the miter gauge for each cut. When two boards are joined by compound miters, the boards slope, rather than rest on an edge or a face. This
