I Had some pieces of flat bar rolled into circle forms at Martin steel in Longwarry, I didn’t have any great plan at the time , just thought they could be used somewhere. I was trying to sort through my internal piles of metal and it seemed to make sense to start to use these. Hence one side is junk and the other is offcuts from Plasma cutting. As I looked at the finished form I moved it about until it looked good on the base. The eclipse idea just suggested itself because it is now in that form rather than perfectly vertical.
