Check Valve Joints

One of the team making new joints for No.10's boiler fittings which will be refitted after the boiler inspector has carried out the annual safety inspection. Today he was working on the two check valves and each requires four different joints to be made. All are marked out on the gasket material,  cut out and the smaller holes made with punches followed by some fine adjustments with a file.
