All the steel for the project, cut to size, and drilled to my specifications.
The paper is rubbings taken from the actual sculpture, which were used to get the exact positioning of the corner bolts on the work. We figured out that there was only 1mm variation from left to right with the positions of the bolts, which is gratifying to see.
Adding a couple of mm to the size of the holes, means everything can be lined up and there’s enough play in the structure.
