Routing a Shoulder

Next, set up the router table with a 'A" straight bit to clean up the shoulders of the tenons. Mark on the router table fence where you need to stop and start each cut and gently push the tenon ends of the boards against the bit, missing the tenon.

Tapered Mortises

When you can press fit everything together, make a simple angle gauge to cut the 5' angle on the narrow widths of the mortises.The 5' angle widens the top of the mortise by about Ye". Split this measurement and mark both sides of the mortise, with a '/i6" offset, for setting the angle gauge. Before chiseling the angle, take a small saw and cut the sides of the mortises to the marks, reducing tearout. Clamp the gauge in place and gently chisel out the angle on the mortise sides. The angle shouldn't go completely to the other side of the mortise.This leaves a softer bend for the tenon to make (see diagram), thereby reducing cracking — something you have to be careful about in a brittle wood such as cherry.

Wedges

The wedges are cut on the table saw using a simple jig (see diagram below).The stock is 3/4" x 6" x 3".That means the grain direction is in the 3" dimension. Make a simple jig to hold the wedge stock while cutting on the saw.

Trimming Tenons

When the glue is dry and cleaned up,make a template out of the cover from a steno pad.The front and back will do.Just tape them together and cut out a couple of holes for the tenons to come through.The more difficult set of tenons to reach are the ones below the top. Set your template up for those. Lay the template over the tenons and cut them flush with the template.
