Restoration is well underway for NIST's 4.45-million newton (equivalent to one million pounds-force) deadweight machine, the largest in the world. The three-story-tall deadweight, comprising a stack of stainless steel discs weighing about 50,000 pounds each, was disassembled last winter for the first time in fifty years.
