| Description: | Thurso Flagstone Works. Caithness. A flagstone polishing machine housed under cover in a shed. The polishing tables move on wheels like those for cutting but are broader in proportion to their length and have splashboards. The polish is obtained by means of flat concentric iron rings, slightly spaced in a horizontal plane, and given an eccentric rotation by a vertical shaft. The polished flags are used for special inside work only, such as flooring of lobbies and granaries, hearthstones, table tops and mantelpieces. |
