I said it had been around for a while.
Mike Cox is the author of the article in MEW.

Haven't got newest MEW yet and it didn't show on the site either.

This is pretty simple design compared to many retractable tool holders. How does this design compare with Martin Cleeves Design "The rectratable and swing clear lathe tool holder" (in WSP#3) . I mean not stating the obvious:
* Flip is more simple
* Cleeve's has internal threading/booring tool option
* Flip is easy to adapt to QCTP, Cleeve's basic design takes a little more effort

andyf:
Pekka, I think the advantage it has over Cleeve's design is that you don't need to retract it at the end and advance it at the beginning of each cutting pass. The disadvantage compared to Cleeve's device is that it won't work on internal threads, as you say.

It is a lot simpler and easier to make than Cleve's design, though.

Roy, I know Mike Cox. He says MEW have been sitting on this and other articles of his for months,  and he is surprised to see that they have suddenly put six of them into the current issue.

Rather than reinvent the wheel refer to this thread started by Bogs

Well worth reading that thread.
BTW, Bogs does state at the beginning it's from an original idea by Mike Cox...

I looked at Bogs tool holder and both are just splendid. When I saw yours I thought I seen that action somewhere else. Then it accrued to me. A "clapper box" on a shaper. The tool cuts in the forward stroke and raises slightly on the return stroke. I must say that both designs are brilliant. I might take my hand at making on for myself. Again I enjoyed the threads.
