Had the two walls and the base cut from .040-in Styrene .. twice .. laminated so I had .080 in thick pieces. The .040 in Styrene appeared .. flimsy. My purpose in using Styrene was that I could be more precise in cutting/snapping.
I’m thinking .. that the vertical separators could be made using foamboard. The pros: I had a couple sheets of the black Foamcore board. The cons: you can’t get it wet. I thought about it though .. the ovens themselves would be cast from plaster. You can’t get that wet either. So. I thought the internal structure .. the vertical division .. the horizontal surfaces that the plaster oven castings would sit on .. could be made from the Foamcore. Driving this was that I was running out of Styrene!
The “ties” sitting on the stone blocks are 85 lb rail. Cool.
One of the interesting things I found out researching for the Coke Ovens is that the rail that will lay across these “ties” was wide gauge (at least for the center dump larrys).
I thought I would generate a Sketchup model of what the finished Coke Oven bank might look like.
