[modeleng] Fw: More on screwcutting

Ken Strauss asked me how I intended to secure the suggested hinge method 
outlined below.   As I said, this is only a proposal - I have never made one, 
or indeed, seen one.
My first reaction is to have a tapered pin with a knurled head to secure it in 
the closed position, or perhaps a hinged clamp.
Has anyone seen this idea in practice?   What do you chaps think?   It has the 
merit of easy construction and use.

Cheers!   Hubert

Hi everyone

I have had several requests for pictures of the device I made for my ex-Emco 
lathe, to facilitate the withdrawal of the tool, when reversing to the 
beginning of the thread.   I have sent these pictures directly by email.    
This system is a lot quicker and easier to make, than the more elegant series 
of retracting devices.

An even more basic device, which I have not made, but which should 
work,certainly on the finer threads, is to hinge the cradle of the cutting 
tool, and swing this upwards to clear the thread on reversing. 

Cheers!   Hubert
