Thread cutting dilemma

[iron bark]

Guys, I would like to say thanks to all who helped me out with threading.

I cut another thread tis morning in some bright steel (I think) and got a much better result thanks to your collective inputs , in particular the feed angle. Pic attached

I still have some more work to do on my tool sharpening
(Edit) it is 3/8 UNF

Hey

That's looking the goods

I seem to stuff up every time I do thread cutting . You need to concentrate 100% , if your mind wanders off in the middle of the job, its usually a stuffup, with me anyway .

Some people run a button die over the thread to make it look better , but real machinists don't do that of course

I run a die over my threads, but not because i cant measure them right, but because threads arnt supposed to have perfect peaks and valleys. Both are supposed to have a small fillet and rather than buying specific thread chasers for all the pitches I work in, its just easy to use a die to get them right without having to think too hard.

That aside, that thread looks a hell of a lot better iron bark!

G'Day,
That looks a hell of a lot better than some of my early efforts - congratulations.
