Abstract: A precision rapid dado tool utilizes a sled and a carrier in order to efficiently create dado joins of varying sizes with a table saw and regular blade. The sled is designed to slide on top of the saw. The carrier rests inside the sled and can slide left and right in the sled in order to allow the workpiece mounted therein to move left and right relative to the sled and the saw blade. A measuring gauge is used to set the width of the dado slot that will be cut into the workpiece. The tool streamlines the cutting of left and right cuts and then the carrier can slide left and right in the sled to remove the center material, and the slot on one workpiece is formed. After repeating on the second piece, the two slots can be joined and the dado is complete.
