A work piece has been mounted between centers and a test cut machined at each end to check alignment of the lathe centers. If the test cut on the tailstock end is deeper than the test cut on the headstock end, the tailstock must be moved _______________.

Acloser to the headstock to reduce the amount of offset
Btoward you to correct alignment
Caway from you to correct alignment
Daway from the headstock to decrease the misalignment
AI Explanation

The correct answer is C) away from you to correct alignment. If the test cut on the tailstock end is deeper than the test cut on the headstock end, it indicates that the tailstock is misaligned and needs to be adjusted. To correct this, the tailstock needs to be moved away from the operator (away from you) to decrease the misalignment and make the depth of the test cuts more uniform. The other options are incorrect because: A) Moving the tailstock closer to the headstock would increase the misalignment. B) Moving the tailstock toward the operator would not correct the issue. D) Moving the tailstock away from the headstock would not decrease the misalignment.
