Here's something new. This is the shell of the boiler for the launch. The perspective is looking at the bottom of the barrel - it's a scotch marine - the coupling front and center is the blowdown. The hand hole to port is for bottom wash and clean-out. On the inside one can see the cluster of four outlets that make up the two safeties, whistle and auxiliary. The main and throttle are further forward. They'll have a drypipe fitted later. The starboard upper hand hole is for washing the tubes. Not bored yet are the feedwater inlets and the other two 1.5 wash-out holes. This is a certified build and will receive an "S" stamp when it is complete. Sorry about the quality of the photo - camera phone.
