Here is the reason for learning the threading...

I got myself a quick change tool holder/post but my lathe doesn't use a "T" nut so I had to make a post bolt to fit the compound slide. The thread is 12 TPI but the nut for the tool post is a metric 2 mm pitch. So I determined to learn what I needed to make one.

What made it complicated for a novice like me was that I had to learn and execute both a metric and a whitworth thread.

One last thing I need to do is get some spanner flats milled into it so I can tighten it down in the compound.
But I got it done. Its a very humble achievement but I learnt a lot about how to use this lathe and about general turning too.

If the "chips" are long like curly hair rather than short "C's" or they are brown or dark blue in colour does that indicate something is incorrectly adjusted like speed or feed rate?
