O k so I've cut a Brazilian threads on QT 15 with T32 control but now for the first time I need to cut ID acme threads they are 2.25 X .3 pitch ,cutting them in 12L14 , I'm kinda nervious cutting this course and acme to boot. So I am asking for some words from the wise, like sfm, how many passes, should I set angle to 28 degrees? Any other comments welcome thanks, Jon P
