Rehabilitation work on the Silver Shaft began in the first quarter of this year and is now completed to around the 5, 700-foot level, which is around 400 feet from the shaft bottom, the company said.
Inside, in a space not much bigger than a three-car garage, was a single shaft-painting machine, a work station where clubs were cut to size and grips attached, and racks containing 40, 000 to 50, 000 shafts and 5, 000 clubheads.
