Cutting the Tenons (Part 1)

Now that the pieces have been cut to length, cutting the tenons is the next step. The procedure is as follows:
First cut the shoulders using a sliding fence combined with precise setting of the blade height. This procedure is repeated twice... once for wide portion of the shoulders (1/2"), and a second time for the shallow shoulders (1/4")
Then the pieces are set in a tenon jig, which allows the accurate and safe cutting of the tenon proper. Again two runs are required... one for the deep shoulders and another for the shallow shoulders.

Finally any adjustments to fit etc are done when the shelf is dry-assembled....

First, cut the shoulders:

These pieces will have tenons cut into them.

The arrangement I used to cut all of the tenon shoulders.

All the tenon shoulders are now cut....

Now that the shoulders have been cut, it's time to cut the tenons proper!
In order to do this safely and accurately, I will be using a tenon jig. (some assembly required)
