The shop-built router jig detailed in this video uses an innovative system to position a workpiece square and centered when cutting matching mortises for loose mortise-and-tenon joinery. This jig relies on two vertically aligned, rotating circles with protruding metal bolts to align a workpiece, and a moveable fence to set the width of a mortise. After watching this video, you should easily be able to use this tool. Use the self-centering mortise jig.
