This piece developed from aiming to make some pieces more 3d  than I had been, I had the curved piece on my bench and it seemed a good base for a circular form. To present it I made the base using some of the many plasmacut off cuts I was amassing. The spiral form was part of a piece of agricultural machinery but is such a tight spiral that it has its own beauty to me. It really was a sort of tidy up piece but it developed quite a nice form.
