time, yellow glue spread on the appropri- ate timbers and things were screwed back together for the last time. When firm, the foundation and ore bin struc- ture were glued to the foam board base. The head house was not permanently at- tached to the ore bins because it needed
To increase strength and structural integri- ty, an interior floor (left) was added to the building. Notice that it’s recessed a bit to fit on the plywood piece glued to the OSB earlier. A piece of ¹/₄″ plywood (below) serves as the locator for the structure. This also makes it possible to remove the struc- ture at any time for additional work.
a double floor. The first floor was made from the ¹/₄″ underlayment plywood used earlier on the stone foundation base. It was cut for a loose fit when pressed into the building. To further help with repeatedly setting it back in the same place, the exact location of the building was marked on the flat and level OSB piece added earlier. A few drops of yellow carpenter glue were spread inside the marks on the oriented strand board. Then the building with the plywood floor was carefully set into the glue. Heavy metal weights were set atop the underlayment plywood to hold everything in place. When the glue was set, the building was removed, more yel-

low glue was applied around the edges of a second floor. Then the floor, made from fiber-
board, was pressed in from the bottom of the building, and the building was set back down onto the underlayment board. The weights were again used in- side to keep the inner floor flat and lev- el. When done, the building could still be lifted without fear of damaging it because the inner floor maintained the structure’s integrity.
Now that the two main buildings of the new scene were in place, it was time to permanently secure the cut stone base and ore bin components together. The three screws were removed one last
to be removed so the conveyor compo- nent and mine building could be addi- tionally detailed. Enough test fitting had taken place by this time that I knew how far this sub-assembly had to be from the track to clear the cab roof overhang of a K-37 locomotive if one should ever ven- ture that close to the structure. It was designed to never have an engine that close, but sometimes strange things can happen. A locomotive would barely clear the foundation walls, but it would dam- age the ore chutes if they were in their lowered position. We will build the remaining struc- ture and conveyor system in next month’s issue.
