The Fourth Dimension

Here things are starting to take shape. I placed the base into position around the shelf system and attached the four posts to the base with four large screws each. It was important to hold the posts as straight as possible during this step.

Next I added some door lintels composed of stacked 1x2's. Here too, these were installed as straight and square as possible.

Not shown here is the addition of two large sheets of plywood to opposite sides of the box. These added stability and provided a place to attach extra shelves in the back side of the TARDIS.
