Fabrication almost complete and air tested of the manifold for my 3.5-inch-to-the-foot scale Koppel rack and adhesion locomotive. Made a pattern for the valve wheels and had Hildebran Designs cast the eight wheels this loco will need. Took a bit of patience to get the all the valve spindles to seat nicely. Now it's time to polish everything up nicely and get the boiler mounted to the chassis and plumbing finished.
