Cutting An Open Mortise And Tenon

ITo center the groove on the rails and stiles, makes two passes. The first pass is with the "X" side against the fence. The second pass is with the "X" side out.

4 To set the width of cut, clamp the rail in the jig and adjust the fence, using the panel groove as a gauge. The cut can be wider than the groove, but not narrower.

7 Adjust the fence so the distance to the outside of the blade is equal to the width of the rail. Then make the cuts by guiding the stile ivith the miter gauge.

21 use this jig to cut the mortise and tenon. Make sure the upright support is perpendicular to the table and the nails are above the maximum blade height.

5 Cut the mortise with two passes. Clamp the "X" side against the jig for the first cut. Then turn rail around (so the "X" side is out) and make a second pass.

8 Mount the stile in the jig and use the shoulder cut to adjust both the height and width of this cut. It'sbest to make this cut on a trial piece first.

3 To cut the mortise, set the height of the blade by using the groove in one of the stiles. The height can be right on, or lower than the groove, but not higher.

6 The first step for cutting the tenon is to make a shoulder cut on the rail. Set the blade height for th is cut to the bottom of the mortise in one of the rails.

9 If the mortise is cut slightly wider than the groove, this means the tenon will also be wider, and small "fins" mil remain. Trim these off with a chisel.
