3.Select and install the appropriate straight router Bit and set your depth- of-cut. It’s best to make a trial cut in a piece of same-sized scrap stock first, to “prove” the location and depth of your cut, before cutting your actual work- piece. Adjustments to the position of your groove can be made by moving your MARK V Worktable in and out.

Similar adjustments can be made for cre- ating odd-width grooves (or dadoes) by starting with a Bit that’s narrower than your intended groove or dado, then mov- ing the MARK V Worktable in or out to widen your cut.

4.Turn on your router motor and feed the workpiece from left to right (against the rotation of the Bit), maintaining a steady pressure against the fence during the cut (See Fig. 31).

Dadoes

The dado-cutting process is identical to the process for cutting grooves, except that you will need to make a wood back-up block to hold the workpiece perpendicular to the Fence and guide it through the cut. If your cut is to be 90° to the edge of your

workpiece, be sure your wooden push block has a 90° corner.

Place one of the block’s 90° edges against the Fence and the other against your workpiece . . . then use the block to push the stock through the cut, as shown in Fig. 32.

NOTE

If you’re planning to cut a dado that is to be at an angle other that 90°, you’ll need to make a push block with one corner cut at the same angle as your intended dado. Then, position one edge of that corner against the Fence and the other against your stock as you guide it through the cut.

WARNING

Always use push sticks, push blocks, and similar safety devices to keep you hands out of harm’s way when mak- ing your cuts.
