Here is a custom day bed frame I made for a customer. I did not totally cut the 1 1/2" material with carvewright. I just designed them on the software and cut a 1/8" deep path. Then I cut them with a jig saw, sanded and routed. Next I screwed em all together with 6" timber screws. Kind of fast and nasty but money was not there for mortise and tenon joinery.
