Backrouting

Usually, I'll set the bit to the correct height and use the fence to control the depth of cut (see drawing). I start with the fence positioned for a light cut. Then I gradually move the fence back between passes. Taking shallow passes removes less material at a time, giving you a smoother cut with minimal tearout.

past the bit. (I actually rout into the backer board for about an inch or so, as you can see in the lower drawing below.)

The backer board supports the wood fibers as the router bit exits the cut, preventing tearout.

One task that I frequently rely on my router table for is cutting rabbets. And I find that it's pretty common to get tearout along the upper shoulder of the rabbet. This kind of tearout has a lot to do with the direction that the workpiece is fed into the router bit.

When routing in the "normal" direction on a router table (from right to left), the cutting edges of the bit remove material from the workpiece as they exit the cut. As a result, the bit tends to chip fibers along the edge of the workpiece.

But by feeding the workpiece into the bit from the opposite direction (backrouting), the bit is cutting as it enters the workpiece. So you'll eliminate most tearout.

The only problem with backrouting on a router table is the tendency for the bit to grab the workpiece and pull it forward, or kick it out away from the fence. This is especially true when taking a heavy cut using a large bit. However, if done safely, there are occasions when backrouting can really help to avoid tearout.

The trick to backrouting safely is to take a very light pass (about V32" deep), as shown in the upper drawing at right. This initial pass establishes a clean, crisp upper shoulder for the rabbet. Once this is done, you can remove the rest of the waste by routing in the opposite direction, just as you see in the lower drawing at right.
