The drum ring sections were returned to the shop this morning. They were flipped and then we began the final welding and grinding. We will begin the fabrication and welding of the giant drum skin tomorrow. This afternoon we also levelled and assembled the pieces of the base out in the parking lot. We will pour twelve thousand pounds of concrete ballast into the base in the morning to finish them off. After we finish the fabrication of the drum pieces we will bring in a crane to do a test assembly in our yard. We will document this tricky process by video to assist the Arctic Circle installation team.
