To properly cut even numbered threads using the lathe thread dial indicator shown in the illustration, you should close the lathe split or half-nut on_______________ Illustration GS-0084
AI Explanation
The correct answer is A) any line on the dial.
To properly cut even numbered threads using the lathe thread dial indicator, you should close the lathe split or half-nut on any line on the dial, not just the even numbered lines. This is because the thread dial indicator is used to determine when to engage the half-nut to continue the threading process, and it does not matter whether the line is even or odd numbered. As long as you consistently engage the half-nut on the same line, you will be able to cut even numbered threads correctly.
The other options are incorrect because C) closing the half-nut on odd numbered lines only would not allow you to cut even numbered threads, and D) closing the half-nut on even numbered lines only is not necessary to cut even numbered threads.
