ABSTRACT:
A jig or frame with a pair of reference pins adjustably attached thereto so that a pointed bottom of the pin can be positioned in a crack between two pieces of hardwood floor strips. A router is slidably attached to the jig or frame and an adjustable stop is provided for limiting the distance that the router can be moved back and forth. This distance is typically adjusted so that it will move only the width of a hardwood strip and the router is positioned so that the bit thereof can move only from one edge of a hardwood strip to the other edge of the hardwood strip when the reference pins are set in the crack between such hardwood strip and the next adjacent hardwood strip.
