How to Make Wide Cuts in Wood

Wide cuts in wood, also known as dados, are used to fit pieces together to form perpendicular joints between pieces, such as bookcase sides and shelves. These grooves, or slots, can be done in a number of ways. The standard power saw blade leaves a kerf, or cut, approximately 1/8-inch wide. Wider cuts can be made by taking repeated passes with a standard blade, but a router table or specialty dado blade on a table saw are two of the best methods.

Instructions

  1. Router Dados

    • 1

      Choose a router bit with the correct width for the cut you need. Install it on your router. Turn the two collet nuts that are opposite each other. Turn the outside nut counterclockwise and the inside nut clockwise to loosen them. Insert the bit and then tighten the nuts by turning the inside nut counterclockwise and the outside nut clockwise.

      Release the barrel latch and twist the router to adjust the height of the cut. Position the router table fence the correct distance from the bit, measuring from the closest tip of the bit to the inside face of the fence. Clamp the fence in place securely.

      Start the router and run the work piece over the bit with the face against the table and the edge placed firmly against the fence to maintain proper spacing. Keep your fingers clear of the bit on both sides of the bit.

    Table Saw Dados

      Select the correct thickness of blade. This is done by combining the two outside cutting blades with a varying number of thinner chipper blades. Turn the arbor nut counterclockwise to loosen and remove it. Fit the blades onto the arbor and replace and tighten the nut.

      Adjust the depth of the blade with the height adjustment wheel, typically located under the table and on the right side of the saw. Position the table saw fence the correct distance from the blade. Lock it in place.

      Start the saw and pass the work piece over the blade, with the face of the work piece placed firmly against the table and the edge riding smoothly along the fence to maintain the proper spacing. Keep both hands well away from the blade as the work piece passes over it.
