The next step is to construct the tenons. I made sure to really practice a couple until I was satisfied with the technique so I wouldn’t bag the actual pieces. I went through 3 different attempts to figure out what works best with my shop and my hands. I attempted all hand cut, bandsaw cut, and tenon jig on table saw and stop on sliding miter saw. I chose the latter based on the results overall. I marked the tenon thickness using a knife gauge to ensure it was centered, then measured the distance and marked off using the same gauge. From there I drew the 45 angle along which the shoulders were to be cut. Having that accomplished, I set the sliding miter saw at 45 degree bevel and set the depth. I cut that to the level of the tenon, or just shy of it and then finished the cheek of the tenon on the tenoning jig on my table saw. There were two different heights, as you can imagine, intersecting the 45 angle. The finished result is below.
After getting all 8 tenons cut, I fitted them to the mortise to create the underlying support structure of the table. The tenons had to be persuaded a bit to fit into the mortises by a bit of racking of the frame but in the end it worked out fine.
