The panel can be produced so that it finishes flush with the stile and rail
assembly or so that the panel is “raised”. This is accomplished by raising or
lowering the bit so that the tongue of the finished panel moves up or down. In the illustration above, note
that the face of the panel is in the down position. If the bit is moved down, the panel will mount proud of
the stile and rail. If moved up, the panel will finish closer to flush. Use scrap lumber to make a cuts until
you have produced your desired height.
Shown below are other profiles that can be produced using router bits from Grizzly Industrial, Inc.
These panel bits can be used with 5⁄8" - 3⁄4" stock. The undercutter enables the
cutting of the panel section of the door in one single pass. The cutter is designed to produce a 1⁄4" thick
tongue which can float in a 5⁄16" wide by 3⁄8" deep groove in the door frame. This provides an approximate
1" to 11⁄8" reveal for the door panel edge. If the door frame is being made with a standard stile and rail bit,
many of these are designed with a 1⁄4" wide groove.
