To prepare for the joinery for the stool’s frame, I needed to come to terms with the angles at which I was going to set the angled mortise-and-tenon joints. Since I’ve never done one of these at an angle before, I felt that I might take a little extra time in preparing the various tools necessary to make the joints.

The first step was to create a full-scale drawing of the joint. Interestingly enough, a joinery book I have also says to do this, but I must confess that I didn’t read that before I’d gone through with the process. As I drew up this thing on graph paper, I realized that I had goofed up some of the critical marked measurements on the computer drawing, though the image of the stool itself was correct. I might go back and fix this in the image that I posted before, but I’ve got other stuff to do now.

With the drawing on a clipboard and a straight board clamped to one side of the angle on the drawing, I set a sliding T-bevel:

After this was set, I realized that I was getting a little ahead of myself, because I hadn’t yet come up with an arrangement for the frame pieces. So I did that:

Then I marked each piece with its position. As an additional indicator, I also roughly marked where the wood will be cut at an angle, so that I don’t accidentally cut an angle where it’s supposed to be straight:

In the preceding image, the piece on the left is a stretcher, and the center is a leg, which will tilt to the left. The marks here indicate the way the stretcher will meet the leg, and how the leg will rest on the floor.

With all of this setting and marking done, I precisely marked the bottom of one of the legs with the T-bevel and a marking knife:

Finally, I sawed it. I don’t have a photo of that, but I guess you’ve seen pics of me sawing stuff before.

Next time, I’ll get down to the business of cutting the joints.
