I built this horizontal router jig from plans featured in an old issue of Shopnotes magazine vol. 12 issue 68. The jig excels at routing mortice and tenon joinery and slots for concealed hinges. The plan has quite a long list of hardware. I ordered some of the hardware on line and spent a couple hours rounding up the rest of the hardware items at local hardware stores. I did make a couple alterations and improvements on the plan including ball bearing slides for the table travel feature.
