Pin Router for a Sears Radial Arm Saw

Step 4 Secure the upper portion of the frame

A 5/16 inch eyebolt fits closely around the saw's motor shaft.  You may have to open the eye just a little to make it slide onto the shaft.  Notice the washers used as spacers between the eye and the back of the upright frame member.  Between this and the angle iron, the router is mounted very securely.  Naturally, the saw's motor does not run when the pin router is in use.
