8 TPI Acme left-hand thread. 5/8″ diameter. ( I think. Have not checked.)

You can buy standard threaded rod to suit here https://kingston-engineering.co.uk/ and probably various other places.

Thanks guys,

Yes it seems that mine is 3/4″ as well. Why on earth isn’t this info in the manual !

Also thanks about Kingston.

Probably because its a user manual and need to know basis etc. Yes I had it right first time, 3/4″. 5/8 is the core diameter and the diameter of the plain bit on the end. There are other suppliers of suitable threaded rod mentioned in old threads if you search around the old forum.

Be sure to get left hand thread if ordering a length of threaded rod to make a new leadscrew!
