I know there is the swing up tool and the much copied George Thomas retractable but the toolholder that appealed to me most was that offered by Multifix.

A YouTube video showing the simple inner workings of the Multifix provided a couple of useful screen captures which served as a starting point.

I do not own a Multifix toolpost, I have a variation of a Dickson, so the greatest deviation from the original retractable was the mount. Another deviation was the use of a formerly 20mm square indexable toolholder, turned and ground to a diameter of 16mm. The body of the tool is 1045, the bushes, 4E cast iron and all the other components, excluding fixings, 4140.
The tool works nicely. Until now nearly all of the metric threads I have cut on the lathe have been cut manually with a spindle mounted crank handle. Here is one of the tool's M8 height adjustment screws under power at 100 rpm -

And finally, a special thank you to Peter Fou, Alan and Piers.
