Arm, Upper back support, and brackets.

In the last six years I don't think I've used a dado stack more than once or twice.  So when I bought the Saw Stop I decided not to buy the dado cartridge.  So for the half lap joints on the upper back brace and arms I used the router table and miter gauge with a 1/2" bit.  It took quite a number of passes but worked very well.

I used the Festool MFS to make the mortice in the leg for the arm.

After squaring the mortice corners and some light work on the tenon the fit was very good.

Rather than make the brackets in two parts and connect them with a dowel I made a single piece pattern, transferred the shape to the stock and created a single piece bracket using a scroll saw. the pattern is on the left and partially cut bracket on right.
