I just purchased a large hobby lathe. It’s an Axelson-Clearing Model 2516, manufactured in 1960, with a 40-horsepower drive motor, about 18 feet between centers, weighing roughly 25,000 pounds (weight estimated by the crane operator). I intend to power the machine with (qty 2) 40 horsepower rotary phase converters, wired in parallel. My problem is that I’ve been unsuccessful in locating any literature on this lathe (e.g. wiring schematic, parts list, operator’s guide, lubrication & maintenance requirements, etc). I am particularly interested in the air interlock – where the machine will not energize without being fed a source of compressed air. Why? Any help would be greatly appreciated!
