Building the Timberline No. 1 mine
The exterior walls of the bunker head house (above) were covered with black craft paper to represent tar paper. It was carefully torn (right) around the area where the stained stripwood would be visible and glued so that the underlying siding could be seen. The windows and doors (below) were inserted into their respective openings and trim boards added to the removable roof. The rolled roofing was then glued in place. The bunker’s roll roofing was cut from the same craft paper used for the tar paper siding.
the three chutes was removed with a hobby knife. Larger vertical timbers were glued to the sides in their respec- tive locations.
The large corner timbers and the di- agonal supports for the bunker are ap- proximately 18 scale
inches square.
The smaller vertical timbers that run up the front and rear faces and serve as guides for the three chute doors are 12″ square timbers. The stripwood used for the ends and faces of the bunker represent 3″×12″ lumber. Because the sloped interior floor would be visible if and when the chute doors are opened, it was also covered with the 3″×12″ lumber.
The ore bunker sub-assembly was test-fitted to the top surface of the stone foundation base. Three mounting screws were used to secure it to the base. To prevent damage, these two components were separated often dur- ing the construction process until the point where they had to be locked to- gether permanently.
The head or sorting house, the struc- ture that sits atop the ore bins, was constructed next. Again, the Cadrail drawings were used determine the size of the walls, then they were cut using a table saw. The paper templates were used to mark the locations of the win- dows and door openings on the fiber- board material by making tiny pin pricks in their corners. When the paper drawings were lifted off, I simply con- nected the dots with a hobby knife. A corner cutting tool that I purchased from Micro-Mark was used to cut out the openings. The tool was mounted in my benchtop drill press and used to “nibble” away the excess material. Please note that the drill press wasn’t running, but simply used as a tool to

press the razor sharp edges of the Mi- cro-Mark tool through the fiberboard. The openings for the doors and win- dows were dressed with sanding sticks and the window and door castings were test fitted in their respective openings. The exterior of the head house was going to be covered with black craft paper to represent tar pa- per. I wanted to have one location on the front wall where the horizontal sid- ing boards would be visible because of the torn paper. The fiberboard was milled away to the same thickness as the stripwood I planned to use. The milled space extended a short distance beyond the area with the torn paper. With the milling over, the side and end wall pieces were glued into a box
shape. Three openings were cut in a floor piece to suggest holes where the material from the conveyor coming from the mine would fall through into one of the ore bins below. When that piece was ready, it was glued in place to help hold everything together as con- struction progressed. Wood flooring stripwood was glued to the floor with Aleene’s Tacky Glue. To allow the head house to be removed, a frame of thicker stripwood was glued to the underside of the floor so that it would easily fit into the top of the ore bin component. The black craft paper was glued to the fiberboard with the Aleene’s glue. When the paper reached the area where the horizontal boards were, it was torn and glued so that it extended
