I am almost finished with the straight tenons that go through the end pieces of the frame. Almost, in that the ends will be shortened and beveled, but I will hold on that until the entire frame is ready to glue, so that they don’t get damaged until then. The two tenons are very straight forward but they do show and I took my time so that there were no gaps. First I just nibbled away at the cheeks with my table saw.
After I sawed the cheeks, I used a handsaw to cut the shoulder on the narrow side of the tenon and the width of the cheeks. Then to get that perfect fit, I used my shoulder plane to plane the shoulder to fit.
Next I again planed the cheeks until they fit as well
Finally assembling the first pieces of the frame, placing them on the full size drawing shows that I am right on.
Next will be cutting the eight diagonal tenons on the shorter pieces.
