It is easier to … It is easier to single point a thread if you mount your cutter up side down and run the lathe in reverse. Then you dont need to worry about crashing into the shoulder. And for crying out load speed that thing up.
I have cut may threads on a manual lathe it works just fine to plunge straight in with a carbide insert. 29deg compound angle is what they teach in school but most folks in the trade go in @ 90.deg works fine and much less math.
It seems like you … It seems like you don’t like to disengage the leadscrew. Like my self. Just afraid we losing so much time with forward reverse forward reverse.

Yes true!!! But cant you not still see the point!!!
its a 24 mm THREAD …
its a 24 mm THREAD not a 24mm bar
Why would you be …
Why would you be screwcutting if you had specific die for that bar size??? Its a 24mm bar, that would be one big die!!!!!!
Mate..learn about …
Mate..learn about speeds and feeds!!!!Stainless a big whoop!!! Try it at a 90 degree angle!!!
Yeeeikes that …
Yeeeikes that sqeaking! make it stop!!
Don’t you have a …
Don’t you have a threading die you could run over that?
But you could …
But you could reverse at Fast mode instead of slow.

yes it’s slow, …
yes it’s slow,remember it is a big 24mm thread in stainles steel and I have not ed it up meaning it has not had to be done twice
this machine has no …
this machine has no start dial on it!
It’s probably a …
It’s probably a lathe meant for inch threading, meaning the chasing dial is useless when cutting metric threads.
