Step 4: Drop the fixture groove over the Table Pin, turn on your router motor, plunge your rotating bit into the workpiece about 1/4" and start moving your fixture (with workpiece attached) in a

Step 5: Repeat the process for each groove in your fixture.
Step 6: Remove your completed project from the fixture, clamp a new workpiece blank into position and repeat steps 4, 5 and 6.
Routing against a pin using a profile fixture
Our example profile fixture shown in Fig- ure 20 is used to cut the shaped tops of fence pickets. Similar fixtures could be used for the tops of wall sconces, shaped fence or porch rail balusters and similar projects. You can even make
Blank workpieces can be inserted and re- moved from profile fixtures very rapidly and they’re usually much easier to make that

However, this lack of guiding grooves means that you must be certain to maintain a con- stant, steady pressure against the edge of the fixture throughout the routing process. A momentary loss of concentration could ruin your project and result in personal injury.
Here’s the
Step 1: Screw the appropriate sized guide pin into the center hole of the Router Table Insert and align it with the same sized router bit, as explained previously.
Step 2: Position the workpiece on top of the fixture with its tip either flush with or pro- truding 1/8" beyond the end of the fixture so the router Guide Pin will engage the fix- ture before the router bit begins cutting the workpiece. Tap the workpiece firmly with a mallet or the heel of your hand to “seat” it properly in the fixture.
Step 3: Cut one side of your profile. Once again, it’s important that you be careful to maintain a constant, steady pressure against the Guide Pin throughout the cut.
Step 4: Rotate the fixture and cut the oppo- site side of your profile. Remove the workpiece and repeat the process with all subsequent workpieces.
