Figure 10-18. A router bit can be used to form edge grooves if this setup is employed. The feather board keeps the workpiece flat on the table.
As shown in Figure 10-18, grooves are cut with the Mark V in the horizontal position. A fence extension and feather board provide guidance and support as the workpiece is fed through. The depth of cuts given in “General Routing” apply. If it's tough to feed the workpiece, the workpiece chatters, or the cut is rough, you are probably cutting too deep. Back off and make repeat passes instead. The same setup can be used to form rabbets or tongues.
Figure 10-19. Use the miter gauge and miter gauge stop rod when doing cross grain work. Feathering at the end of the cut is characteristic but is easily removed by jointing or sawing.
Handle cross grain cuts by working with the miter gauge and using the miter gauge stop rod to determine the depth of cut (Figure 10-19). There will be some feathering at the end of the cut, so work on a piece that is wider than you need. Remove the chip by making a light jointer cut or by sawing.
