The Mill building houses a complete blacksmith's double forge, made by A Handyside, where a major part of operations here took place, often involving two smiths, four strikers and several apprentices.
It was used for making and repairing implements and wrought iron tools. In addition there are fans driven by the line shafting and bellows on either side of the forge. The left hand bellows was made by Allday & Onions
To see a working forge like this intact is an exciting experience and it is very popular on open days when visitors take the opportunity to make their own poker or toasting fork under the supervision of Society demonstrators.
