Abstract
A router table assembly utilizing a steel plate table top penetrated by a stepped opening having slightly non-concentric round holes. A table top insert is received in the stepped opening, which insert is a round plastic disk having a ledge formed by a disk portion of smaller diameter which matches the smaller hole in the top and which smaller disk portion is slightly offset from the layer diameter portion. The disk is positioned in the top opening and is rotated approximately one-fourth revolution until the cam-like action of the non-concentric portion locks the disk in place. Jaw-like router base clamp mechanisms have plates adjustable to the size and shape of numerous router bases and can be positioned once, after which the router can be removed and remounted in exactly the same position if assured centricity in the table top.
