No idea of the thread but is this a real problem?

Thanks for the details of Clarkson feeds screw size and the suggestion of an M10 replacement.

Mine is floppy enough for replacement being desirable when round-tuit supply is sufficient.

I guess the standard is 5/8 BSF but M10 x 2 means that some form of useful dial is possible. The pair are cheaper than a BSF tap too.

Just been out to check my spare Mk1 table, with 100 divisions on the handle dial.
0.619″ diameter 10tpi left hand.
My 55° thread gauge seems to fit the profile nicely.

No dial on my Mk 1 and nor room for one either.

Dunno how old mine is but Clarkson had a steady programme of improvements during the life of the Mk 1 so quite likely that later ones got them. No pictures showing a dial on a MK 1 in my collection of manuals and instructions. Although a manual featuring both Mk 1 and Mk 2 clearly shows a dial on the Mk 2.

There used to be a website with loads of pictures and info of Clarksons (apart from Lathes.co.uk) The site owner used to track every one that appeared on ebay. I don’t seem to have a link and it didn’t appear in the first couple of search pages. Anyone know what I’m talking about?
Meanwhile this is useful https://bedroom-workshop.com/grinder-clarksondrawings/0grinder-clarksondrawings.html

Actually it might have been the site above – I assumed it would have clarkson in the main  title when I searched. https://bedroom-workshop.com/
