I originally had money in my bid to buy the HEMA Chain Mortiser/Slot Cutter or Mafell Chain Mortiser/Slot Cutter for this timber framed barn in Portola Valley California. However, I had to lower may bid to get the job and I still needed a way of cutting the hidden 52 -- 3/8" x 8" deep steel knife plate slots in the timbers. I designed a slotter/mortise jig that I called the California Knife Plate Slotter - Mortiser for the 6x6 post and another jig that I called the Okie Knife Plate Slotter - Mortiser for the 5 1/2" x 9" GluLam Beams.
