Stone Planing Machine

This rare machine is an example of the first type of planer for shaping granite blocks, invented in Scotland. It is probably the last survivor.

Machine tools such as this were an important advance in building construction in the mid-1800s, particularly in the North East. They made it possible to accurately work hard granite on a large scale enabling it to used as ‘ashlar’ or dressed stone. This innovation revolutionised quarrying in the process turning Aberdeen into the famous ‘Granite City’.

The stone planer was invented in the 1830s by James Hunter a quarry manager at Leysmill near Arbroath. This particular machine was built by Nicol Esplin, a company founded in Leysmill by a descendant of Hunter. However the company only lasted for 7 years, from 1906 to 1913.
