They will follow workpiece edgesthat are either straight or curved. The pilot preventsthe bit from making too deep a cut; and holding thepilot firmly in contact with the workpiece edgethroughout prevents the cut from becoming tooshallow.Whenever the workpiece thickness together with thedesired depth of cut (as adjusted by router depthsetting) are such that only the top part of the edge isto be shaped (leaving at least a 1/16 inch thick uncutportion at bottom), the pilot can ride against the uncutportion, which will serve to guide it. See Figure 18.However, if the workpiece is too thin or the bit set toolow so that there will be no uncut edge to ride the pilotagainst, an extra board to act as a guide must beplaced under the workpiece. This "guide" board musthave exactly the same contour -- straight or curved-- as the workpiece edge. if it is positioned so that itsedge is flush with the workpiece edge, the bit willmake a full cut (in as far as the bit radius). On theother hand, if the guide is positioned as shown inFigure 18 (out from the workpiece edge), the bit willmake less than a full cut -- which will alter the shapeof the finished edge.NOTE: Any of the piloted bits can be used without apilot for edge shaping with guides, as preceding. Thesize (diameter) of the pilot that is used determines themaximum cut width that can be made with the pilotagainst the workpiece edge - the small pilot exposesall of the bit; the large one reduces this amount by1/16 inch.TOP EDGESHAPINGWORKPILOTWHOLE EDGE SHAPINGGUIDEFig. 1817
