4.Cut an outline of the spindle and cutter from the center of the stock selected in Step 3, as illustrated in Figure 25.
Note: Make the outline as close as possible to the cutter and spindle without interfering with rotation.

5.Create countersunk mounting holes in the zero-clearance fence so that the screws and T-nuts removed from the split fence can be used to secure the new fence to the fence assembly in the same manner.
ALWAYS use hold-downs or featherboards and push sticks when shaping small or nar- row stock. These devices keep your hands away from the spinning cutter and suffi- ciently support the stock to allow a safe and effective cut, reducing the risk of personal injury.
6.Secure the zero-clearance fence to the fence assembly, check for proper clearance, con- nect the router to power, then run a test piece by the cutter to verify the results.
Free-Hand Routing
Irregular or free-hand routing, as illustrated in Figure 26, takes a high degree of skill and dexter- ity and is done without the protection and aid from the fence and guard. The most dangerous part of free-hand routing is beginning the cut, when the cutter first contacts the workpiece. Often the workpiece will tend to jerk or kickback, presenting an injury hazard to the operator.
Free-hand or irregular routing greatly increases the chance that the operator may lose control of the workpiece, which could result in serious personal injury. Therefore, a starting pin or block and a custom guard or workpiece holding jig MUST be used.
