Make perfect raised-panel doors with matched router-bit sets
Learn the secret to using rail-and-stile router bits to create raised-panel doors without accumulating a pile of sawdust and test cuts in the process. Richard Babbitt has some 90 of these doors under his belt, and he has devised an easy way to remove the trial and error from the process. His system uses only one extra rail, which is used to set the height of all three cope-and-stick bits precisely. There are no further test cuts, no multiple setup blocks, and no fancy jigs.
