The cremation urn measures 8.25 inches in height, 6 inched wide, and 6 inches in depth. The capacity is up to 142 cubic inches. The general rule of thumb is one pound of live weight equals one cubic inch of cremated ash.
Note about the Spanish windlass style closure system: Spanish windlass was used for centuries to secure cargo in the holds of ships The basic principle is that of a tourniquet. A rod is slid under a line, then turned so that both ends of the rod pass over the top of the line. The rod is turned until the desired amount of pressure is achieved. Then the end of the rod is secured to the line preventing it from unwinding.
