Lunar self launching station

I've been thinking how to alter the design of my space station launched from the moon's surface.

Its supposed to have all its materials coming from the lunar surface itself.  It is also supposed to be very simple to make which requires you to use as few tools as possible.

In this new design I'll try to alter it to use less material.

To achieve that we will put 4 nodes that will be opposite each other in pairs giving you 4 nodes all together, and they will balance off each other while spinning like a top in space.

Each node will be a habitat with sufficient equipment to do a variety of tasks.

There will be a cylinder to which all the nodes are attached.  This cylinder will actually double as a rocket that will place the vehicle into orbit.

The nodes will be deployed once in space.

Once the vehicle is in space it will be spun up and the nodes will be spun out via a cable which is attached to the cylinder, or rocket.

Update:

This is now being designated as a series.  Part 2 is here.    Part 1 can be linked from part 2.
