Building the Timberline No. 1 mine
The supporting base for the mine building (above left) is made of OSB material and has been set in place atop an existing mountain. Plaster will be added around the edges to keep it in place. The Grandt Line window casting (above right) has the glaz- ing installed. Two pieces were cut from the glass used in 35mm slide mounts. Open- ings were measured with a set of calipers and then scored with a carbide tip cutter and snapped. The edges of the glass were sanded with a sanding stick for proper fit. A small machinist’s square aided in position- ing the etched roofing material (left). It was etched in Archer Etchant and after rinsing, was further weathered with a wash of “Sweet and Sour” rusting solution and al- lowed to dry. Stripwood was glued around the edges of the of the roof panel to hide the edges of the fiberboard material.
on the mountain top and weighted down with a couple of heavy weights. Plaster was mixed and placed under
the edges of the board and allowed to set. When hard and dry, the board was again removed and the packing tape
taken off. The base could now be set re- peatedly in the same place. The mine structure, built earlier, had
A support ring (left) for the tall smokestack was made by soldering a square piece of thin shim brass stock to the end of a short length of brass tubing one size larger than the stack. The square stock was carefully trimmed away until a small circle remained. A knife was used to cut out an opening in the center of the shim stock. then four holes spaced equally apart were made around the perimeter. After excess tubing was re- moved from the collar, it was blackened with Archer’s Etchant and Birchwood Casey Gun Bluing solution (above). Green trout fishing line was then threaded through the holes, knotted and secured in place with cyanoacrylate.
