Precision Jig for Neck Chamfer Tool

California shooter Mark LaFevers has come up with a slick, adjustable fixture that delivers a precise, repeatable inside-neck chamfer every time. He uses a Holland Case Mouth Chamfer Tool with a 14° cutter, but this set-up works equally well with other chamferers with an extended handle. With Mark’s tool jig, the Holland Tool inserts through the top, indexing vertically off a shoulder. A small recess is cut in the center of the wood base for the case head. The tool mount can be raised or lowered with the adjusting bolts on all four corners. Simply slide a trimmed-to-length case in the middle, give the Holland Tool a few spins, and you get a perfect, identical chamfer every time. Now that’s ingenuity! Mark isn’t planning to produce these commercially, but he’s happy if someone wants to copy his jig design.

NOTE: In the photos above, you see an older version of the tool. Hollands has improved the design of its current 14┬░ Chamfer Tool. The cutting head now has a 3-flute design that provides a smoother, chatterless cut. The head is now made of carbide so it cuts faster and holds its cutting edge longer. This tool is available from Holland’s Shooters Supplies for $32.00 (item CMCT-CAR).
