Storage Tanks - Part I

Started the first of four storage tanks for the oil terminal. I am using a 2.5" conduit coupling for scratch building these tanks. I cut down the length of the coupling and glue on a .100" octagon styrene cap and sanded down the excess.

After destroying a etch brass stair way trying to add a spiral stairway to the tank. I gave up for etch brass caged ladder (I am planning on a different access approach on some of the other tanks). The man-way hatches are made from solid round styrene.
