Double Bar Dadoing Guide

Maybe die best quality of the double-bar guide is that it traps the router. Regardless of the feed direction, the router can't veer oficoursc. A corollary-is that since the router is trapped, you can give it room to play side to side, thus producing a cut—a controlled cut—that's wider than the bit being used.

I made this particular version of the double-bar guide after talking to my fellow woodworking writer/editor David Schiff. He described a jig used by a carpenter friend. The carpenter wanted to pare down the array of tools and equipment he had to haul from job site to job site—without sacrificing versatility. Versatility encompassed being able to cut dadoes for 5/4 stock. A version of this jig enabled him to cut a range of dado and groove widths, including the 15/i<rinch-wide ones for the 5/4 stock, with a single bit—a '/2-inch straight.

As you can see in the following photos and drawings, the guide consists of two crossbars glued and screwed to a fixed fcncc. The crossbars are perfectly perpendicular to the fixed fence. When either crossbar is tight against an edge of the workpiece, the fence will be at a right angle to that edge.

The second fence is attached in a way that allows it to move. The distance between the fences deter mines the width of the dado. When they are as close together as the)' can be. the router baseplate will just fit between them. And when the)' are as far apart as they can be. the baseplate will have about VA inches of play. So. with a '/2-inch bit. you can use this jig to cut dadoes between Vi inch and P/< inches wide. The challenge is to adjust this movable fence so it is both the correct distance from the fixed fcncc and parallel to it. (You can adjust this fence to help you cut a tapered dado. While you might never want a tapered dado, you might want a tapered dovetail slot. See the chapter "Sliding Dovetail Joints.")

This double-bar dadoing guide traps the router between two fences, so you don't have to worry about it veering away from the fence. Giving the guide versatility is the movable fence, which allows you to cut dadoes two to three rimes wider than the bit.
