Not so. The rocker/cradle pic in #3 uses LOTS of screws. See all the dark plugs?. Every one hides a screw; most likely a large sheet metal screw.
Maloof developed a joint made with a router that was detailed in Fine Woodworking many years ago. The strength of the joint is from lots of contact area and an exquisite fit. The screw keeps it tight.
I should have included ‘in some of his pieces’. Thanks!
I’m wondering if I ever rode one of his rockers as a kid
