5.Create countersunk mounting holes in the zero-clearance fence so the bolts, flat wash- ers, and star knobs removed from the fence boards can be used to secure the new fence to the fence support 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 router bit 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 support, then make sure the fence is parallel to the table T-slot.
7.Check for proper clearance, connect the router to power, then make a test cut to verify the results.
Free-Hand Routing
Irregular or free-hand routing, as illustrated in Figure 21, 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 router bit first contacts the workpiece. Often the workpiece will tend to jerk or kickback, presenting an injury hazard to the operator.

a starting pin (guard not shown for clarity).
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.
