I’m making interior doors for my house and the backward way I was cutting tenons was tedious and the result was functional but not very clean (think lots of glue). I ran across an excellent design by thetinman over at LJ. His was more than functional, it was beautiful. Mine is merely functional.
The jig rides the fence while the rail workpiece gets cut on a stacked dado. The jig is reversible with one small fence for lengthwise cuts and one large fence for widthwise cuts. It will be in use this weekend as long as my wife doesn’t complain about the noise waking the baby. :-)
