Saw off two strips of wood ¹⁄₂ an inch thick, 1 inch wide and 17 inches long. Bore fifteen ³⁄₄ inch holes 1 inch apart measured from their centers in them; glue a strip of felt or thick cloth to the wood in each one and slip the tubes in the felt lined holes as shown in [Fig. 112].
How to Play the Tubaphone.
—To play this peculiar instrument use a couple of felt covered mallets; these can be made by winding a little ball of string around one end of each stick which should be about ¹⁄₄ inch in diameter and 8 inches long, and then covering it with felt. Beat the tubes with the felt mallets in exactly the same way you do when you play the xylophone.

—This is one of the easiest musical instruments to make and the music produced by it is impressive in its tone and depth.
To make it saw off a board, ³⁄₄ or ⁷⁄₈ inch thick, about 12 inches wide and 22 inches long and screw a block 1 inch square to each corner for it to rest on. Get eight binding posts[113] of the size shown at [A in Fig. 113]; drill eight ¹⁄₈ inch holes in the board, 4 in a row with the holes 5 inches apart and have the rows also 5 inches apart, and then screw a binding post into each hole.
