I have Amanda router bits 49670 & 49672 but am baffled as to how to set them up to make long, through mortices to duplicate the original, hand cut ones.
Does anyone provide instructions for the use of these bits?
Traditional stile-and-rail work is joined with mortise-and-tenon joints. A decorative profile, sometime referred to as "sticking", is shaped around the inside edges of the stiles and rails to embellish the appearance of the frame. Where the stiles and rails intersect the decorative profile is coped.
A cope is a reverse of the decorative profile. The cope is shaped on the ends of the rails directly above the tenon. When the cope and sticking are joined together during assembly, the decorative profile appears to be mitered.
Amana Tool offers five different profiles bit sets for creating stile-and-rail frames. Set no.49673 creates a classic cove-and-roundover profile. Bit no.49670 shapes the profile and bit no.49672 creates the cope.
The sets are designed for thicker stock, such as that used to create window and door frames and shutters
Before shaping and coping, first cut the mortise-and-tenon joints. If a groove is to be used for a panel, keep in mind that the shoulders of the tenon must be offset in length to compensate for the decorative profile. If a rabbet for glass is used, the tenon shoulders can be the same length as long as the rabbet and decorative profile share the same depth.
Once the joinery is complete the next step is to shape the cope. The stock is fed past the bit face down and the top of the bit should come close, but not touch, the tenon face. Afterwards the profile is shaped on both stiles and rails, a groove or rabbet is cut, and the framework is assembled.
