A large, rigid router table insert plate for incorporation into user-made router tables. Constructed from thermoset phenolic, it features two concentric snap-in rings and three hole sizes (98mm, 68mm, and 32mm diameter). Concentric rings and radial lines on the underside facilitate easy centering of the router. The plate is molded with a slight crown (0.8mm) for distortion-free cuts and includes corner clips for clamping to the table underside. It can be mounted to 19mm tops with a 6.35mm deep x 12.7mm wide edge rebate. Users will need to drill the plate to suit their specific router make and model. Safety device accessories should also be fitted to user-made router tables. Includes 2 concentric rings and 1 lead-on pin.
