Little publicised by its makers - possibly because its manufacture seems to have been confined to the 1940s and 1950s - the ball-bearing headstock late-model Hardinge "split-bed" lathe took the general layout and bed profile of its relative the Cataract Toolroom Lathe of the twenty-five earlier. However, with a "double-height" bed, screwcutting gearbox and power feeds it was more akin to the early Cataract Quick Change Swing Precision Lathe - but with a much heavier build. Some elements of the design were to be carried over to the next significant Hardinge models, the highly successful flat-bed HLV and HLV-H of post-WW2 years. The use of the term "split bed" was first used by Hardinge owners to distinguish this model from the far more common later HLV and HLV-H models where the top surface of the bed was flat across the full width - and not split into the two conventional parts as on the TL and T10. If any reader has an example of the TL or T10 , the writer would be very interested to hear from you..

Branded as the LP59 this split-bed had a shorter bed than normal and is thought to have been a-naval machine
