I found that building most of the frame, then dropping in the z-axis "h" section made life far easier.
Building the assembly that is present on page 33 separately, and then putting together the rest of the v0 frame was far, far faster.
This would involve building the outer 10 extrusions first-- the bottom square (4 extrusions), the top y-axis square (4 extrusions), and the verticals between them.
Once those are built, you can simply slide in the 'H' assembly as appears on page 33 from the back.
After discussions in the dev team we decided to not implement this suggestion. The current instructions provide a better shot for getting the z stage trammed.
