Edge Jointing
Jointing the edge of a board involves using a straight cutting router bit to remove wood from the face of the board. The result is a perfectly flat and square edge.
Always feed the workpiece against the rout- er bit rotation direction, as illustrated below. Otherwise, the workpiece could be aggres- sively pulled from your hands, drawing them into the spinning router bit.

To joint the edge of a workpiece:
1.DISCONNECT ROUTER FROM POWER!
2.Secure a straight cutting bit into your rout- er according to the router manufacturer's instructions.
3.Install the smallest table insert in the router table that allows the router bit to freely rotate.
4.Raise the bit just above the top of the workpiece, then rotate it by hand until the cutting flute is perpendicular to the fence boards.
5.Secure a shim between the outfeed fence board and fence support. The thickness of the shim controls the amount of material removed with each pass. (see the illustration in Figure 16).
Important: To reduce the risk of kickback, do not take more than 1⁄8" off for any one pass.

6.Place a straightedge against the outfeed fence board, then adjust the fence assembly so that the straightedge is also against the bit flute, as illustrated in Figure 16.
7.Make sure the fence boards are parallel with the table T-slot, lock the fence assembly in place, and tighten all knobs.
8.Connect the router to power, then perform the cut (see Figure 17).

To reduce the risk of hand injury from acci- dental contact with the spinning router bit, ALWAYS make sure the fence and router guard are properly positioned and secured before connecting the router to power (does not apply to free
