Field Kerfing Required Equipment

1. FREUD - 9/16” Depth Slotting Cutter Set (figure a) or equivalent

2. Hand Router (figure b) - minimum of 1hp or equivalent tool such as 3 wing slotting cutter (figure c)

Best Practice Field Kerfing Guidelines

1. Insert slotting cutter tool into the hand router
   1. Use a manufactured kerf plank (figure d) as a set up guide to confirm tool height
   2. Place the blade in the kerf
   3. Set tool height
2. Perform a test run on a scrap plank
   1. Speed rate for hand router: 1400-1800 RPMs
   2. Feed rate for hand router: 8-12 ft/min
3. Kerf planks as required
   1. Maintain tolerances - planks arrive with a .415” kerf and field cut edges must be re-kerfed to 0.500”

Required Equipment Rabbeting

1. FREUD - 1/8”,1/4”, 5/16”, 3/8”, 7/16”, 1/2” Depth Rabbeting Bit Set with interchangable bearings (figure a) with 1/2” Shank or equivalent tool

2. Hand Router (figure b) - minimum of 1hp or equivalent tool

Best Practice Field Rabbeting Guidelines

1. Insert rabbet cutter tool into the hand router
   1. Use a manufactured rabbet plank (figure c) as a set up guide to confirm tool height
   2. Use bearing designed to cut a 1/8” depth rabbet (figure d)
2. Perform a test run on a scrap plank, once height is set
3. 1. Speed rate for hand router:1400-1800 RPMs
   2. Feed rate for hand router: 8-12 ft/min
4. Rabbet as required
   1. Tolerances - planks will arrive with a 1/8” x 0.157” rabbet cut and the field cut planks must be re-rabbeted to 1/8” x 0.157”
