Hello Colin,
I must admit you did catch me out there for a moment. I was uncertain as to whether I had actually done a Design of Screwcutting Clutch for this lathe.
Luckily the drawings are still on the computer file, despite two computer and one drawing package change.
As regards to whether this design was ever finished I cannot say. Some of those who start out wanting to fit a clutch to their machines fall by the wayside and lose interest. You will realise that this then stops any feedback from the participant(s) and I no longer know if it worked. My memory problems also do not help on this front.
That said, without seeming to be Big Headed, the high number of clutches that I have designed to date, have all worked as intended. The last and final one being for my Emco Compact 5.
I have all the drawings in DWG format, can you handle this Format? If not I could convert them to PDF but this will take a while.
Regards
Gray,
