    Default Hercus 260/9" B and C inch to metric threading chart

    I found some errors in the Hercus supplied plates for cutting metric threads on imperial lathes. This only applies to the C and B models. The errors corrected are in the 1.25mm, .75mm and .5mm pitches. See the ammended chart attached.
