For sale is a 10 Inch diameter D1-6 Lathe Chuck. Made by Skand Chuckfabrics AB, Sweden. I am saying that it is a D1-6 because I looked up some tables with dimensions. But I am providing a picture of its back with a yardstick, so that you can decide for yourself if it really is D1-6. The distance between outer edges of the cams is 6 inches. The chuck is 10 inches in diameter. It was made in Sweden, home of the Nobel prize and a tradition of fine workmanship. A matching chuck key is included. Chuck operates smoothly and comes from a stockroom of a fine American stamping factory.
