Ah. Munty has a very sophisticated concept of an X frame....
The one I originally posted about is, er, an X - nothing more, nothing less :oops:
On a traditional row of beans, the pairs of canes are tied together at the top, so you end up with a triangle cross-section. The pairs of canes are then joined horizontally along the top with more canes.
The problem with that, if you're only 5'2" like me, is that it's hard to harvest the beans towards the top because they are hanging down inside the narrow point of the triangle, at height.
I either read about, or saw, the idea of tying the canes together in the middle - so the cross-section is like an X. The horizontal bracing canes are where the X canes cross. It would be far easier to draw it than describe it, except I always got Es for art... :cry:
In this design, the higher beans are hanging down from the top half of the cane, thus being on the outside.
As for stability, ask me again in September
