"Study for 'shipbuilding on the Clyde' - Using the Bevi" image: A group of five men using a 'bevi' (or bevelling iron) on a steel frame in the plater's shed. Two other men are hammering in the iron 'dogs' used to keep the frame fixed in position on the perforated floor. Another figure stands holding a hose to the upper left of the composition. A stack of pre-bent frames lies in the upper background.
