          I added pre-painted Northeastern corrugated metal roofing,
        
        
          which is embossed paper, to the walls, overlapping the sides
        
        
          and bottom of the section to seal the building.
        
        
          The advantages of using the paper panels are, there isn’t any
        
        
          shiny metal showing, and it is easy to weather. This is just one
        
        
          way to construct the metal-sheathed part of the tipple.
        
        
          In his article, Ron Pearson drew the external walls of the tipple
        
        
          on .060” styrene. He scribed the styrene and snapped it apart,
        
        
          giving him straight edges.

          3. East side of the tipple showing the covered pit that
        
        
          was mistaken for another shaft. The steps have yet
        
        
          to be installed as well as the waste chute from the
        
        
          shaker house.
        
        
          Ron marked the locations for the windows and doors and cut
        
        
          them out. He then glued Evergreen 9” H-beams in the corners.
        
        
          Over the styrene sheets, he applied Campbell’s corrugated
        
        
          metal cut to 4’ wide sheets.
        
        
          The Northeastern and Wild West Models corrugated paper
        
        
          could be used with this type of construction as well, but these
        
        
          products weren’t available at the time Ron built his models.
        
        
          Those of you in larger scales may substitute either foam-
        
        
          core board or thicker styrene for stronger walls. Also, the
        
        
          Northeastern corrugated paper is available in O scale.
        
        
          
            Alternative methods
          
        
        
          Another method for making the walls is a combination of
        
        
          open frame and solid styrene. For the areas where the steel
        
        
          work is visible, such as through the large opening at the rear
        
        
          of the tipple, using the open steel work so that the bracing
        
        
          can be seen, as in the prototype photos, and solid styrene
        
        
          walls when it can’t.
        
        
          However, using this method requires the corrugated metal
        
        
          or paper to be finished on both sides in the visible areas, as
        
        
          with the open frame type of construction. No matter which
        
        
          method you use, do not enclose the building over the tracks
        
        
          until the loading bin has been installed. This will make for
        
        
          much easier installation.
        
        
          Once the framework was complete, I installed the dumping
        
        
          floor of the tipple. To better support the floor, I added additional
        
        
          H-beams. The floor was installed using individual 2” x 12” scale
        
        
          lumber and was stained with Builders in Scale Silverwood.
        
        
          The mine rails come from the mine to the tipple across the
        
        
          ramp. To locate the mine rails, find the center of the structure
