All of the tenons are cut and fit. Not perfect but the last ones went much better than the first few.
I got wrapped up in laying out and cutting the mortises. Later I realized there is no lower rail on the front of the two larger tables. (they cannot nest if there is a rail in front). I’ve got some walnut. I think I’ll use to plug the mortise. Maybe the contrasting color will make it look like I meant to do it. I may try to cut it as a bow-tie key.
Next up is is some decorative slats for the sides. I’ll follow up with more pics then.
