MagneticScrolls Sketchbook - Starting from the beginning again

[MagneticScrolls]

I spent a lot of time (far too much) on these but, I'm still stuck on this exercise. I'm having trouble drawing a lot of it even though it seems like it should be easy. Attempting to project middle of the ground plane forward can lead to trouble if I don't make enough space on the left hand side for the projected box to be seen. 
I also ran into trouble making the right side of the spiral. Once the peices come towards the viewer it's a little difficult. I also have trouble seeing where I'm placing things once there are too many lines on the page.
