Router table fence system

A router table fence for use with a router table top, comprising:

• (a) a top spar and
• (b) two bottom spars, each of which spars:
• (i) has a top face, bottom face and two side faces and
• (ii) is fabricated of extruded aluminum having a generally square cross-sectional shape with a laterally centered, longitudinal T-shaped slot in each face, and
• (iii) first structure on a first face of one of the spars for engagement with second structure on an opposite face of another of the spars so that the one spar can slidingly engage the other spar with at least a second face of the one spar maintained in substantially the same plane as a second face of the other spar.

A method of accurately positioning a router table fence on a router table top relative to a router cutter protruding above the router table top, comprising the steps of:

• (a) fixing the router table fence in a first approximately correct position on the router table top with fence locks that attach to the fence and table top on opposite sides of the table,
• (b) taking a first test cut in a workpiece by passing a portion of the workpiece through the revolving router cutter while maintaining the workpiece in sliding contact with the fence,
• (c) positioning a micro-adjust fence stop against the front or back of the fence at one edge of the router table top
• (d) loosening the fence lock adjacent to the one edge of the router table top,
• (e) measuring on the workpiece a distance the fence position needs to move relative to the router cutter,
• (f) using the micro-adjust stop to reposition the fence contacting the micro-adjust stop by twice the distance, and
• (g) tightening the fence lock adjacent to the one edge of the router table top.
