The Eddgwick arrived!
Pete.:
You can use that method for all screwcutting which would make the dial redundant unless you want to start making multi-start threads.
AdeV:
Yes, I have that plate on mine - unfortunately, although complete, it's so badly bashed about that I can't read it. I'll get my camera with macro lens on it later, hopefully with a suitably big & clear picture I can make out the missing bits. My mobile phone camera just isn't good enough.

I've made out essentially invisible writing on unreadable tractor tags like that by shooting with a decent camera, and then cranking up the magnification, contrast and/or brightness values in a photo editor. You'd be amazed what it can show up. :thumbup:
AdeV:
Well, I just did a little experiment - and you're dead right, the screw cutting dial does not work for metric threads...
I'll just stick with Whitworth... :)
IIRC, from watching an American lathe tutorial, even TPIs can start on any number or half number & will thread correctly. Odd numbers I think have to go on the whole number only. But, I could be wrong, it's been a long time since I watched that video.

This may be of help assuming your gearbox can produce the metric pitch
It shows that you can disengage the half nuts
