routing mortise

You can get a fairly crisp joint with simple jigs and a router.
I usually square off the round corners of mortises with a chisel.
The slight recess around the mortise is for the end of the horizontal member.
This slight recess prevents any gaps showing with seasonal movement of the timber.
