Had some time yesterday to build the conveyor motor housing. This is not anything super detailed since no one will probably ever see it.
The sides are 60 mil styrene which fit very nicely inside the H-8 columns. I drilled 1/16" dia holes into both side walls, inserted the rods and glued them in place. I made small side covers and glued these over the holes. I won't be rasing/lowering the hook and will most like glue the conveyor motor housing in the center of the overhead track again since I doubt no one will see it unless they look real hard.
I cut and glued a top cover then a smaller piece to look like a lift up lid to get inside. I then glued a ladder to the H-12 column on one side of the building so some one can get to the motor. I will glue some HR-8 railing later today.
