[pongobear]

It's probably got about half an inch of metal with a thread cut on it. Hold a ruler alongside, count how many whole threads there are in half an inch, multiply by two and you get the "threads per inch" or "tpi".
I agree that it is likely to be 16 tpi.

Yes 3/4" = 19.05 mm

You say you 'counted 8 threads' but you don't say over what distance. If there were 8 crests in 1/2" (12.7mm) then that would be 3/4 x 16 as suggested by loftyhermes and is a 'Standard'.

just had a look and I'm getting six threads in half an inch ?? help lol

 

[Glynne]

Just googled “nu tool lathe spindle” and The Toolpost & Peter Child both suggest it is 3/4” x 16 tpi.
Have a look at the sites as the quote a model number.

Make sure you are counting whole threads - one crest, one valley.

Aren't these things like Clarkes and others with a peculiar thread?

Here's a pic if it's any help

 

[banjerbill]

No pic here!

If it's the model with a single round pole as the bed it is definitely 3/4" x 16.

[pongobear]

No it's not the round pole model I'll see if I can get pics off of ebay

Go on ebay, buy yourself a 3/4" X 16tpi nut, which won't cost much, and try it for size.

Can you post a picture of the turning tools, because they look suspiciously like cheap nasty ones. I hope I'm wrong but if they are cheapies then they are likely to put you off turning through sheer frustration.

Ordered nut so that should help me narrow it down....as for chisels not sure if cheap or expensive but I been using em with my mini lathe and they cut well .....or better than the cheap nasties supplied with mini lathe I'll see if I can upload

 

[pongobear]

Couple of pics to help if poss

 

[graduate_owner]

They don't look like some of the cr@p that I have seen, fortunately, and if they cut well then that's fine. I have read comments about some which won't keep a decent edge and will bend or break easily. Trying to work with tools like that is so disheartening. Not trying to criticize, I just thought it worth mentioning in case you were getting grief from your tools but might have thought it was your technique at fault.

Also, if your nut fits, then that could be the basis of a home made faceplate.
