Forest of Dean Stone Firms

Stone Working & Quarrying

Scotch Derrick crane


The Forest of Dean in Gloucestershire, England, has had its own mining laws since the fourteenth century and these "rights of free miners" were extended to the extraction of stone in the 1830's.

Bixhead quarry has supplied Pennant sandstone for at least 500 years. Many prominent buildings in Britain have been built with this stone, reputedly including London Bridge. The quarry is now registered as an important geological and archaeological site. A Scotch Derrick crane lifts stone blocks of up to 10 tonnes after they have been split from the face with wedges.

Reciprocating stone saw

Deeper in the forest 1km to the east is the stoneworks of Forest of Dean Stone Firms Ltd., where the stone is cut and dressed.

Belt-driven horizontal saw frames, a modern horizontal saw and a circular saw cut the stone to size with diamond-tipped blades.

Horizontal saw frames (originally driven by waterwheels) have been around for centuries - the ancient Greeks and the Romans were known to use them to cut the stones used to build their cities. At the Roman city of Jerash in Jordan, archaeologists have reconstructed a water powered stone saw on the site of such a machine where partially sawn stone blocks for pillars were discovered.

Mason dressing stone


Once the stone blocks have been cut to size at the Forest of Dean Stoneworks they are then dressed by hand by masons using pneumatic tools as well as the traditional mallet and chisel.

There is a big demand for traditionally produced stone for the restoration of old buildings - many of which are now showing the ravages of time.

Stone planing machine

Ornamental features such as chamfers or bevels on the edges of lintels etc. can be shaped by stone planing machines.

A 48 minute 'enhanced' compilation, No.31: "Forest of Dean Stone Firms" shows work at the quarry and all the stone-cutting machines in action.

Since this recording was made in 1992, the Dean Stone Firms have been modernised, many of the old stone saws have been removed and replaced by modern wire-cutting and disc cutting machines.
