Problem: To true round stock in a three-jaw lathe chuck when extreme accuracy is not required usually means tapping the workpiece while the lathe is turning.
Problem: To true round stock in a three-jaw lathe chuck when extreme accuracy is not required usually means tapping the workpiece while the lathe is turning. Is there a simpler way?
Solution: Snug the workpiece in the chuck and rest a wood block (large enough so the tool bit does not hit anything) on the compound as shown in the sketch. Turn on the spindle and start cranking the crossfeed in. The workpiece acts like an edge finder and trues up easily. Stop the lathe and securely tighten the chuck for machining or center drilling.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
