Cutting Finger Joints On A Radialarm

To cut finger joints on a radial-arm saw, rotate the mounting to set the blade in a horizontal plane. To support the work, replace the saw's main guide fence with a small raised table and fence made from MDF.

Clamp four workpieces together on the raised table, with their ends projecting by the required depth of cut. To offset the fingers for one half of each joint, raise two of the components on a packing strip that equals the width of the saw cut.

Begin by adjusting the blade to cut open notches in the raised workpieces, then lower the blade in stages to cut equally spaced fingers on all four components simultaneously.
