Iron Chaplets

Chaplets are used to support a core from the bottom,or to anchor it from the top to prevent floating. However it is quite as important to secure it against lateral shifting due to unequal pressure of the metal while pouring. This is frequently done by wedging a double headed chaplet between the mold and the core (or between two cores), using shims where necessary to provide a tight fit, or by tilting the heads of a one piece chaplet and using it as a wedge. In either case, the chaplet must necessarily be placed after the core has been set, and is held in place by friction only.
