🔍 Key Concepts

• Taper per foot and how to scale it for a different length • Difference between total taper on diameter vs setover on radius • Relationship between workpiece length and required tailstock offset

💭 Think About

• First, convert the 18-inch workpiece length into feet and figure out the total taper on the diameter over that length if the rate is 1/2 inch per foot. • Then ask yourself: does the tailstock setover equal the full change in diameter, or only half of that change? Why? • Compare the number you get for the total change in diameter to the answer choices after adjusting for whether you’re dealing with radius or diameter.

✅ Before You Answer

• Be sure you’ve converted 18 inches into feet correctly before using the 1/2 inch per foot rate. • Confirm whether the 1/2 inch per foot taper refers to change in diameter, not radius. • Double-check that your final number represents the tailstock offset (a radial movement), not the total change in diameter.
