Given the already complex exterior, the only interior modeling I did were representations of the molasses tanks in Building No. 1 in the southwest cor- ner of the structure. I also added an ac- cess hole in the foam board base to fa- cilitate adding limited lighting at a later time.
North side
I began the project by cutting and fitting the north wall sections (adja- cent to the BART line), attempting to replicate the varied contours and odd angles there. This was primarily a gal- vanized gray metal building. I used Evergreen Scale Models .060″ corru- gated metal sheets, firmly pressing down on my HO metal ruler laid over the sheet. I then scored each cut multi- ple times with a hobby knife to get a clean cut. The thicker ribbing makes these repetitive scores necessary. Part of the north wall view and the complet- ed wall can be seen in the photos. The north side roof line was beveled out and the mid-roof had trapezoidal shaped ends. As evident, there are var- ious angles on both the mid- and top roofs, as well as on the walls them- selves. The asymmetric gables created an interesting visual effect. I had to es- timate the component angles and pro- portions of each wall that made up the overall north wall. Here, I got lucky and got things right on the first go around. However, such was not the case throughout the twelve-year jour- ney building the structure.
Several components had to be redone repeatedly until they were correct. Ex- amples of these re-do’s include the big pipes as seen in the prototype photo, some of the fragile window muntins, the
complex, soldered small piping
work on the north side near the cur- tained shed and the odd convex fan atop the tall cooling tower, which was the most challenging item. The base on which the model was built is foam board, but I learned later that MDF (medium density fiber) board would have been a better choice to avoid warping.
Cooling towers and fan The outer shell of the fan housing
The cooling tower (top) was one of the most conspicuous parts of Red Star Yeast. The fan housing atop the structure was made using a sewing spool. A concave shape was need- ed and the spool proved perfect for this; it was covered with corrugated sheet stock. The south side of the building (above) had a Spanish style curvature on top of the wall.

was concave and had ribbing. My ques- tion to myself was how to model this fan and housing without casting it? I decided on using a concave shaped sewing spool and affixed corrugated cardboard, which had the flexibility to conform to the curvature of the spool, to it. The spool’s interior opening was then plastered in to form a bowl shape to accommodate the fan. A propeller blade detail from Stewart finished the piece and it fit perfectly.
