After doing a bit more reading I've decided I don't need stretchers at the top of the bench. If I mortise the legs into the top and dowel them there should be no movement and stretchers would add little to anti-wracking. Also, the stretchers may actually be a negative in that they would limit the clamps I could use plus they may get in the way of bench dogs and holdfasts.
So, the top stretchers were mated to the bottom to beef them up a bit. I haven't drilled the holdfast holes yet or cut the tenons, maybe next week. The legs have the edge routing complete and are waiting for the holdfast holes to be drilled.
In picture #2 you may notice a larger profile routed in the front stretcher. This is the beginning of the rail for the dead-man to slide on.
