   I recently made a mortising jig described by Carol Reed (router lady) in her book: Router Joinery Workshop: Common Joints, Simple Setups & Clever Jigs.

   It works quite well and only takes an afternoon to construct. I can only find one picture of it and it is here:

   The router base rides on two rails that are adjustable with a veneer press screw.

              That is extremely neat, and with your knowledge of routing a benchmark. May I make what I hope is a pertinent observation?

   Your jig, by clamping to the work sides, assumes first class stock preparation. Could it reference off one true side, the narrow bottom side, so that notwithstanding errors in planing the other sides mortices plunged at each end of a rail were automatically in plane, and shoulders might then be squared to those mortices? I am sure that users of jigs, encountering problems of line up, blame the jig when the fault lies in too many varying reference points. I hope the above makes sense!

   The jig needs only one straight edge to reference to. Once set, the edge guides & stops take over. No matter what the size or shape of the work, the mortice dimensions are always the same, and independent of crummy milling.

   The work face is always flat up against the bottom of the panel so all mortices are square to the incedent face; a really forgiving tool.

    

   Now then, to flip a stick over and hit the same mortice shadow requires good milling.

   Routs on a daily basis.

   What I like most about this jig is simply the size of it and how it holds the piece. What I don't see is a work piece stop so that you could reference the piece against a positive stop. For example, when routing mortise in table legs for aprons. It seems with this jig you have to align it to each mortise you want to cut. I may be wrong, but I don't see this in the pictures anywhere.All in all, I do like it. Although, I have a Triton router and it has a proprietary fence and wouldn't work unless I made a special base.- Josh

   Sticks come in any and many lengths. To provide an integral work stop for an infinite number of parts, while a cool thing indeed, is simply not practical. One can handily clamp an end stop to the bench as needed.

   And thank you for comments.

              Thank you for the clarification.

   I made a fancier version of this jig, which has the adjustability you are looking for.

   The author (Jeff Miller) does not use his jig for loose tenons, but it is possible to do so.
