Benefits exclusive to McDonough

  • Flat Ways are split on Headblocks to create a 21” front way for less costly & easier replacement.
  • Headblock Ways are fully machined, 1 ¼” thick Kromite for longer wear.
  • All cylinder ends have replaceable swivel bushings eliminating binding & cylinder damage.
  • Knees are made from A572 steel, a thinner and lighter steel with increased strength.
  • Dogging the log and cinching it back against the knee are done on Round Ways for 'straight line' simplicity, which prevents binding that a linkage style will cause.
  • Tong Dog made from 1 ¼” T-1 Steel (1 ½” on Premium Duty) with keyed replaceable teeth.

Additional Benefits

  • Board Dog Carriages are preferred over Tong Dog Carriages because they dog the log faster and are superior to holding a smaller cant.
  • Stepped Flat Ways on Headblocks allow knee to ride on separate surface than log, to maintain accuracy.
  • All wear strips used are made from Nylatron GSM, which provides better accuracy than UHMW.
  • Frame is fully boxed and gusseted for added strength, with access holes to critical areas.
  • Knee Face Plates are only 2 ½” wide Kromite, to allow more accurate taper sawing.
  • All Board Dogs in Knee and Tong Dog are made from T-1 Steel for long lasting wear and have 1/32” clearance for accuracy, replaceable by removing one bolt per tooth.
  • 16” diameter Vee Wheel and Flat Wheels are either long lasting Polymer Composite, or T-1 Steel hardened to 320/360 Brinell.
