Parts and joints

I've got most of the parts for the table base ready for cutting and laying out the joinery. I have to anticipate the strength of the wood receiving the joints, walnut is a fairly strong wood but I need as much wood left around the joints for strength and still get the proportions I want. My design has a fairly lean detailing for the legs and stretchers, yet the foot cross piece will have some shaping and mass reduction later. These parts have shaping and curves that I'll cut after I get the joints cut and fit tight.
