By-PRODUCTS PLANT Part - 15
I started adding some detail to the final cooler/benzol towers. I started building the stairway from the top down. Even using the pre made Plastruct stairs and railings you need to pay a lot of attention to spacing and straightness otherwise the stairs will end up looking sloppy. I also added the platforms and a walkway to the final cooler. This walkway was for accessing some sort of injectors (water?) and was removed at some point, but I am using it. I am also still busy casting valves, narrow gauge car bodies, and now, plumbing fittings. I made a new mold for 3/8" diameter elbows and tees, with flanges. First castings were a little foamy looking and of course there were a few air bubbles on the large flanges. Trying again overnight - see tomorrow what we get.
