Pictures posted show the thickness testing of the boiler and firebox of engine 1702, to see how thick the metal is. This is very important so as to determine if the engine is safe to operate and at what steam pressure the locomotive can be run. The process consists of laying out a grid with all the lines at 4 inch intervals then taking a ultrasound in the center of each grid.
Western builders made great progress on our new steam shop building this week. They finished up on the siding and insulation on all walls and have made headway on putting the roof on so the building can be in the dry. After the roof is finished then they can proceed on interior work such wiring and more insulation.
As far as the 1702 is concerned we started cutting on the backhead of the boiler so we can get ready to begin the boiler check. We also marked a grid layout on the firebox and boiler so that we can check the thickness of the metal. We have to determine the thickness of the metal before we can proceed with the restoration!
