Grizzly H7507 owner manual Free-Hand Routing

5.Create countersunk mounting holes in the zero-clearance fence so that the screws from the fence boards can be used to secure it to the support board in the same manner.

6.Secure the zero-clearance fence to the sup- port board, check for proper clearance, con- nect the router to power, then run a test piece by the cutter to verify the results.

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 sufficient- ly support the stock to allow a safe and effec- tive cut, reducing the risk of personal injury.

Figure 35. Illustration of free-hand cutting with a

starting block.

To reduce this tendency, use a starting block (see Figure 36). This will allow you to anchor and slowly pivot the workpiece into the cutter as the cut is started, making the operation more stable and safe.

Free-hand or irregular routing greatly increases the chance that the opera- tor may lose control of the workpiece. Therefore, a pivot point MUST be used to control the workpiece while free-hand routing. Loss of control of the workpiece could result in serious personal injury.

Irregular or free-hand routing, as illustrated in Figures 35, takes a high degree of skill and dex- terity 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, where the cutter first contacts the workpiece. Often the workpiece will tend to jerk or kickback, presenting an injury hazard to the operator.

block being used on a shaper.

With the fence assembly removed, you MUST use a router bit with a bearing to guide the workpiece through the cut and limit the depth-of-cut. Also, use a jig or fixture to hold the workpiece so that your hands can be kept at a safe distance from the router bit while cutting.

In many situations, it is safer to use a router that is not mounted to the table to perform free-hand routing. Make sure to use a router bit with a bear- ing.
