1.) Gather Materials
Round up at least 5 feet of Type M ¾-inch copper tubing, seven eye screws, five No. 6 1-inch machine screws and nuts, nylon twine, and 1 x 6 lumber.
2.) Map Pipe Mounts
Center a 4½-inch-diameter circle in a 5½-inch-square cut of lumber. Mark the circle at five equidistant points. Insert eye screws at the circle's center and at all five points.
3.) Cut Pythagoras
Cut five pieces of tubing to the lengths in the table below and deburr. The chime's five notes, which correspond to a piano's black keys, make up the minor pentatonic scale. The notes are pleasing in any order. The ancient Greeks such as Pythagoras were the first to study the link between the length of a vibrating body and the notes of a musical scale.
4.) Tie With Twine
Drill a 5/32-inch hole through each pipe as listed in the table. These hanging points produce the best chime resonance. Insert a machine screw through the hole and fit a nut onto the screw shank. Tie a 7-inch length of twine from the circle of eye screws to the screw shank in each pipe.
5.) Hang the Chime
Use a 2½-inch holesaw to cut a clapper from a 1x scrap. Use more 1x waste to make a V-shaped, 3-inch-long wind scoop. Hang each from the center eye screw. Cut and glue two smaller 1x squares to the top of the first square. Top-center-mount an eye screw in the smallest square. Hang the chime in the breeze and enjoy
