I have got the 9", 6", 4" rests and scraper flat rest.
Also a 1" post for my herald and 5/8 post for SWMBO SIP lathe.
Works out lot cheaper as rests interchangeable between both lathes.

Any one know the thread size ? Measured it at 12mm, but standard m12 nut won't fit, is there another m12 thread, say m12 fine as standard m12 nut looks course compared to sorby thread. Or is actually something different altogether?

Ì am looking at making some jigs or one off rests to attach to it.
 
From memory I think it is 1/2" x 12 TPI. I'll check tomorrow as I bought a die especially.
I'm sure this question has come up before if you want to search the forum.

Edit: M12 x 1.25
