Hazel Mine Tipple - Construction: Support Structure
01/02/2021
This diagram is from the December 22, 1900 The Engineering And Mining Journal where this tipple structure was fully described. It included scaled drawings. In preparation for my building the support structure of the tipple, I studied the architectural design diagram. It includes a scale ranging from 0 to 25 feet, which I copied and rotated 90 degrees and then placed two copies next to the vertical columns. As near as I can tell, the floor of the tipple was supported by 37-foot tall columns (see my orange line on the diagram), resting on the concrete foundation blocks.

The text describes these columns as having been made out of two 10" C-channels welded together to form an H-column. The webbing of the columns was then reinforced with cross-hatchings, as is clearly visible in this end elevation drawing.

For this phase of the construction of this model, I will be building the entire trestle structure as is shown in the diagram. The building-proper I have already completed, so this phase covers the support structure that holds the building up in the air. This diagram shows the tipple as it was constructed in the year 1900. I model 1924, so there were some enhancements made to it over those years. First, a couple of years after its construction, the tipple was extended by two "bays" on the left in this diagram, to cover track #5 (represented by the box car on the left). The last "bay" had no track under it, so I am presuming it was used for loading automobile trucks, which this tipple also supported, for local deliveries of coal. Second, on the right-hand side of the diagram, the tipple was later partially extended to cover the gearing shown in the diagram; the space over the last two bays. That is what my model of the building-proper has. I don't know when that extension was built in the real building. So, this diagram shows 9 columns, but my model will have 11 columns, to cover the two extra "bays" added on the left. I do not know why there were no columns in between tracks #2 and #3. Photos show the same configuration as the diagram. From the diagram above, you can see that there are a total of 4 rows of these columns, so I will be constructing 44 columns.

To build these columns, I bought a bulk pack of Evergreen's C-channel, part #265. These are 0.156" wide, which scales out to 10 inches in S-scale. These strips are 14" long, which scales out to 74 feet in S-scale. However, because the interior "floor" of my tipple building is inset vertically from the walls of the building, some of my columns will need to be longer than 37 feet, so I won't be able to get two columns out of each pair of C-channels. So, by buying the 100-pack (bulk) pack, I can glue two together to create the 44 columns I need, and have a few strips left over as spares.
