This Precision Fence Positioner system is the ultimate and includes the leading split fence design, the Wonder Fence, for serious joinery and woodworking fans. The world's most versatile and accurate movable fence for your router table, drill press, or band saw, gets even more useful in this system which is designed to meet the needs of the most serious woodworker yet easy enough for even a beginner to use. The INCRA LS Super System has all of the precision and versatility of INCRA's other tools, plus a host of new features and design details that set it apart from anything else. The LS positioner's accuracy is +/- 0.05mm - the lead screw's 1mm increments across its entire range, so it's essentially perfect even without the built-in micro adjust. The large micro-adjust knob turns the lead screw against the mating threads, allowing the fence to be shifted in 1/20mm steps to tweak the width of a groove or zero the fence against a router bit. The fence used for the Standard Systems is the Pro-II 28" fence, which features a surface that's machined flat in a milling machine and a T-slot for adding fixtures or adding the INCRA Wonder Fence in the future. INCRA Wonder Fence The Wonder Fence slides into the front T-slot of the Pro-II joinery fence, and it adds adjustability to accept any size router bit and accommodates zero-clearance subfences. The Wonder Fence also adds the ability to very precisely offset the infeed and outfeed fence halves for edge jointing rough timber or setting up for complex moulding jobs like reversible glue joints. The LS Super Systems are available with either 17" or 430mm travel LS units to provide their positioning accuracy. INCRA's patented lead screw positioning mechanism allows any woodworker to quickly set the fence within 1/1,000" (0.025mm) of any desired position. In woodworking terms, that's accurate enough to split the line from a sharp pencil into 25 equal parts! And because an INCRA positioner is mechanical in nature, every fence setup is easily repeatable with zero error, hours or weeks later. INCRA Master Reference Guide & Template Library Provides straightforward instructions and 51 joinery templates (25 templates in the metric version) to slide into the positioner to provide a visual reference for each joint pattern. Those templates can produce a mind-boggling variety of joints - 11 box joint patterns and 29 dovetail patterns are included (or 9 metric box joints and 16 metric dovetails), and each one of the dovetail patterns can be cut half blind, through, sliding, or corner post. INCRA LS Instructional Video The LS systems are topped off with a link to a 1hr, 22min instructional video - this video is loaded with information - how to take advantage of the optional Wonder Fence's advanced features, cut perfect-fitting rabbets and dadoes, and it has full-length instructions for box joints and the four most common styles of dovetail joints.
