One of our skilled volunteers Peter Gransden has been working on the planer* machining the crosshead surfaces.

*For those interested, a planer holds the tool stationary while the table slides backwards and forwards with the workpiece mounted on it. A shaper, on the other hand, keeps the workpiece stationary while the tool moves backwards and forwards. In both cases, the tool pivots on the backstroke to prevent it scoring the workpiece. This mechanism is sometimes called a clapper because of the sound it makes as it snaps shut at the start of the cutting stroke.
