This is picking up on the idea of wrapping the swirling pattern around a sphere. Here I am trying to wrap it around a donut form instead. The high and low points are being cut out with this drill. This is just as I did with the sphere and it seemed to work quite well. This is one of those ideas that is a little hard to visualise before the sculpture is made. I don’t know if it will work. I do like applying a set of ‘rules’ however and then letting it play out. The piece of plywood that the blue drill bit goes through is to help get the bit started in the right place. Each new hole required moving the plywood. Quite a task.
