Progress has been slow on the Jones Chemical Company. I've been busier than I thought I would be this fall, and there hasn't been a lot of time for model building. Anyway, I did find some time on the weekend to install the tank piping. The basic inter-tank connections are 1/8 inch piano wire bent to appropriate shapes as per the article. Corresponding holes were drilled in the tops of the tanks for seating the wires. Although a little hard to see in the picture, the small tank at the rear has a large diameter plastic pipe from a Walthers piping kit connecting the tank to the building. There is also a vertical pipe and valve from the same kit attached to the large diameter tan coloured tank.
I also added clear plastic to the windows and installed a view blocker in preparation for installing the roof. I had plans for adding a large horizontal tank with flashing LEDs inside the building to simulate a bubbling chemical tank, but with this project taking so long - longer than the Bunn's Feed and Seed - I decided to forego that idea and concentrate on wrapping up the project. Next part: installing the roof on the main building, and building the structure that covers the tank pad.
