For use with the ordinary lathe a fast-running, 2-speed ball-bearing countershaft assembly was available that incorporated both fast-and-loose pulleys and an additional round-rope "overhead" drive for the grinding and drilling spindles.
When equipped for production a special countershaft was supplied that enabled stop, start and some speed changes to be made by foot-pedals operating wire links.
