I have a lot of 2 inch by 8 TPI internal threads to cut in cast aluminum,
both left and right hand, and just got the missing parts for an "on end"
style bar thats been in the cabinet for years. I remember someone saying
that they prefer leave the compound 29 degree angle out of it and just use
the cross feed.
Hows that compare to the traditional method for smooth threads?
