The pallet is held in place under the pipes by a spring. When a key is pressed, the corresponding pallet opens, admitting wind into the key channel. Between the pipes and the key channel are the 'sliders'. A slider is a strip of material, such as wood, with one hole for each pipe drilled through it. The slider can be moved via the stop action.

Layers beyond the first two are stacked from this basic building block. If two more layers are consecutively stacked from bottom of core, you can have a 1-2 via, a 1-3 via and a through hole. Each type of via is made by drilling at each stacking stage. If one layer is stacked on top of the core and other is stacked from the bottom, the possible ...
The instrument is made from four-inch (102 mm) diameter, thick-walled aluminum tubing. The total weight of the chime is 653 pounds with the musical tubing alone weighing 310 pounds. The 6-foot (1.8 m) by 8-foot (2.4 m) wooden pyramidal shaped top weighs 225 pounds. The center hung circular wood knocker is 3' 6" in diameter and weighs 64 pounds.
The diameter of a cylindrical bore remains constant along its length. The acoustic behavior depends on whether the instrument is stopped (closed at one end and open at the other), or open (at both ends). For an open pipe, the wavelength produced by the first normal mode (the fundamental note) is approximately twice the length of the pipe.
