Those joints are supposed to be strong enough, but there's no pretty factor to them and we're back to the point that a stationary table is the best way to use them. I just use rabbet joints for all the drawer cases I build. Strong enough and the straight bits are cheap.
I do want to make a horizontal spindle holder for my machine one day. Glad I designed it with enough room. One of the projects I want to design and make is a poker chips box with diamond, spade, heart and club "dovetail" construction. I can imagine each side in a different wood for contrast.
