Note: Since hole spacing is 1/2" and adjustable leg of jig is 24" in length, the amount of taper per foot of cut can be readily set. Each hole represents a taper of 1/4" per foot. Example: Set nail or screw in 4th hole away from 29-1/2" leg of jig for a taper of 1" per foot. Set 24" leg against nail and fasten into end of 24" through 5th hole using nail or screw.
