I used a piece of wood and different plates made of lead. Such plates are used by the local divers when they submerge. My dad helped me cut the lead plates into different lengths with a small saw and I placed them on the piece of wood one after the other from the smallest to the largest, and then secured them with small screws on both sides of each plate. I named my instrument “glockenspiel ladder” because the plates form the shape of a horizontal ladder.
