Sound cycle

Sound 2: On top of the lift the hammer is pushed down again fast when hitting the return log.
Sound 3: Hammer hit the iron on the anvil.

The word "wrought" is an archaic past participle of the verb "to work," and so "wrought iron" literally means "worked iron". The trip hammer is powered by a overshot water wheel.

The Lancashire forge in Olofsfors Iron Works, Västerbotten, is from 1870s. The Lancashire hearth was used to fine pig iron, removing carbon to produce wrought iron.

In the end of the recording you can hear a different sound because some of the wooden wedges in the hammer detach.
