Cummins 3253 Faceplate

It's likely a standard thread. Just match the faceplate to the lathe. Nothing magic here (other than determining the thread, perhaps). There are also converters available if the faceplate you want isn't made in that thread.

Nice! Thank you for your feedback.

A truly non-standard thread if ever I saw one. And not one that Nova supports with their standard adapters. All is not lost though. Hand one of these:

to any machinist along with the internal thread specs and you should have something back in maybe an hour.

As others have said, you first need to know the thread pattern of the heads tock, knowing the Morse taper of the headstock and tailstock would not hurt either. IF its a really weird pattern, get your local machine shop to tur n you an adapter and bring it up to 1x8.
