Things You'll Need
Instructions
Find the center point at each end of the 2 inch-by-2 inch-by-36 inch lengths of hardwood. Drill a 1-inch deep hole in the center of each end of each piece. Coat inside of hole with 5-minute epoxy. Insert threaded rod into each end of the wood.
Scribe a 24-inch arc across each rocker end of the cradle, parallel with the flat edge of the half circle. Drill a 1/4-inch hole 1 inch from the right and left ends of the arc you just scribed, on each half circle. Connect rocker ends to the 2 inch-by-2 inch-by-36 inch hardwood lengths, inserting the threaded rods through the holes in the rocker and capping them with brass acorn nuts.
Lay the 24 inch-by-36 inch sheet of plywood across the 2 inch-by-2 inch-by-36 inch bottom supports. Screw cradle bottom into place with 1-inch wood screws.
Lay cradle sides in place, adjusting side placement until the top edges of the sides will lie flush with the outer edge of the half circle of the rocker. Drill 1/8-inch-diameter pilot holes in each rocker end and in the narrow end of each cradle side, and attach cradle sides using 1-inch brass wood screws.
Sand and stain cradle. Allow stain to dry overnight. Coat cradle with two to three layers of clear acrylic deck treatment and allow to dry for several days.
