ABSTRACT:
Dado shims that are disks of substantially incompressible, flexible, color coded plastic sheet material of uniform predetermined thicknesses having a central arbor hole and a radial slot narrower in width than the arbor hole diameter so that each shim is shaped like the letter "C" and can be distorted slightly during positioning on a saw arbor between dado set blades without removing any of the blades, by slipping the shim over the arbor through the slot until the shim seats on the arbor within the shim arbor hole.
