Hammer cushions are situated in a “cushion pot” or receptacle provided in the drive cap, or in a specially designed accessory used in conjunction with the drive cap. The hammer cushion consists of a stack of materials topped off with a striker plate, that is placed at the point of impact under the ram (falling weight) of the hammer.
