In order to be most economical in our design of the structural nodal system, we produced a universal node. This node is made up of two 1/8" steel plates notched together to form a cruciform shape. In order to increase the multipacity of use, the plates have anywhere between 16 and 18 2" diameter holes. The concept is that as you string your 1.5" diameter tube members through both plates in multiple directions the joint will stay strong.
Problems:
-will need +2in holes to accommodate a 1" pole
-wastes a lot of material
-Different angels require a different amount of clearance
Could be:
-instead of 2 plates there are 4 plates so the poles will only have to bridge 45 degrees instead of 90.
