The massive dirt moving project that is my back yard has been taking much of my time recently and SWMBO banned morticing while our son is asleep (apparently the hammering was waking him up) so progress has been slow.
I have cut the mortices in the legs where the skirt attaches. I used my #45 to plow a shallow groove to guide my mortice chisel and chopped 1/2 inch mortices. Once they were chopped the #45 and a router plane set the groove to a consistent depth to help keep the rail flat. The outer side wall 3/8 inch wide which may be a mistake but it allowed for a longer tenon though I followed the “half the rail” rule for sizing the tenon.
I’m slightly behind where I should have been because on Saturday I had almost finished the first tenon and was just making the final cut when I inadvertently marked the wrong side of the cut and ruined it. Luckily I had not trimmed side rail to final length so I was able to salvage the part (though the tenons are slightly shorter than planned).
