Retracting Tool Holder
Ref: HK 1250
Designed by Mr. G.H. Thomas and described in the M.E. November 1981.
This tool holder readily clamps onto a 4 tool turret or a Q.C. tool holder. Although proportioned to suit a 3 1/2" lathe, it performs perfectly well in much larger equipment. The principal use is for external screw cutting. At the end of the cut the little ball handle is flicked backwards, whereupon the tool retracts clear of the thread. It is unnecessary to wind back the feed handle of either the cross or top-slides, thus the exact position of the tool is never lost or forgotten. The feed screw of either the cross or top-slides is only turned forwards. At the start of the next cut the little ball handle is pushed forwards and the tool is positively returned to its former position.
Our kit includes both ground and bright drawn steel sections, fasteners and spring. Full drawings and instructions are contained in Mr. Thomas book, The Model Engineers Workshop Manual.
