Dentil Mould 2-1/4"

This elegant 2-1/4" dentil measures 2.250" wide by .750" thickness. The profile is comprised of a 1" wide raised fillet on top, connected to a 1/2" rabbet on one side for the crown to sit into, joined to a small radius arc that is attached to a fillet with a cove on the opposite side.

Here is just one way to manufacture this fine dentil moulding; first, find wide boards you can safely crosscut on a table saw, plane to a thickness of 13/16". Using a sled jig on the table saw, mill each cut 1" apart, crosscut the grooves no more depth than 5/16" + .020" (this is what the bottom cutterhead would mill), you don't want any exposed gaps once the crown is installed into the rabbeted area. Rip the board to 2-1/2" widths; this is why you want a wide board to start; this dimension will allow 1/8" to be milled from each vertical cutter head.

Place rubber rollers on the machine's feed system, remove (.000") wood off of the first bottom spindle, mill 1/8" from each side, and mill about .040" from the top cutter head; it will clean up any chipping left from the table saw when crosscutting, the last bottom mills .020". This is an expensive molding, so make sure everything is correct before much lineal footage is milled.
