Re-run part 2/2 by Graham Meek

So far there are designs for my screw cutting clutches available for: the Myford Super 7 (published in my book Projects for Your Workshop, available from TEE Publishing Ltd), the ML7, the Asian Mini-Lathes including the brushless motor versions. MEWS has published the Warco BH 600 which was a combined effort by Graham Howe and myself. The Wabeco follows here, and there is a design for the Emco Compact 8. There is a version for the South Bend 9 & 10" lathes, yet to be published on MEWS. Of course, these can be adapted to suit the Boxfords. Following is the Clausing 100 MkIII. 

In these clutches, the stops are set to determine the length of the thread, and the clasp nuts remain engaged throughout and the carriage is driven to-and-fro by the operation of the clutch lever. The lever is moved in the direction of travel and returned to the neutral by the stop attached to the control rod. By adding a retracting tool slide, production of threads is quick. No need to stop and reverse the lathe motor.

Part one is a general description. Detailed drawings to build the clutch will be in part two.
