I am looking at my next machine, probably going to be a Joe's. While looking at Acme rods I see that the tolerances of most are .009/ft. This is where it gets confusing to me. Is that .009 accumulative? In other words if I run 3 ft could I end up with .027 out? Or does it mean that any place I measure a foot along the rod it will be less that .009 out?
