Cataract (Hardinge) Unfortunately there was never a "Manual" for the Cataract lathe and millers - but there is a wonderful full-range Catalogue showing all the Precision Bench and Screwcutting Lathes (including a complete catalog for the wonderful "Quick-Change" model), Milling Machines, Automatic Gear and Pinion Cutters, Drills and the full accessory range made from the early 1900s to the early 1930s. Although not a Manual, there are many descriptive and illustrative details of the machines' construction and drive systems including Sectional Drawings of the various headstocks.
