Wayne Godshall is making the boiler for my Heisler. I recently visited his shop and was impressed with his operation. He has developed several interesting parts and has some more under development. He doesn't have a website so I volunteered to put this information on the Nelson's Locomotive site as a service to other enthusiasts.
Wayne has as complete machine shop including CNC lathe and milling. He also has a complete welding capability. He does both custom locomotive construction and restoration. He also makes boilers. Wayne is located in Shermansdale, Pa and may be contacted at firstname.lastname@example.org
The photos below show some of the parts Wayne currently has available.
