Good evening and Happy New Year to all,
It's been a while since I did any single point threading on my Webb/Whacheon 17" lathe and even then, I was not that good at it before. Please forgive me if I am using improper/incorrect terminology but if you look at the attached photo of a 5/8 x11 TPI threads I cut, the crest(?) of the thread looks like it's not in the center, it looks like one side cut off center.
The compound is set to 29 1/2 degrees and I was using a 60 degree HSS lathe tool. The corresponding store bought nut threads on fine with little slop, but the thread just doesn't look right to me. BTW, it was a piece of 4140 that I threaded.
In any event, any comments, insight, advice etc. would be most appreciated.
Thank you.
Joe
