Cut off with a power hack-saw a piece of steel 6¹⁄₁₆ inches long from a
bar 1 inch in diameter. This will allow ¹⁄₁₆ of an inch for finishing
the ends and ³⁄₁₆ of an inch for turning the diameter.
An experienced lathe operator would use a piece of steel ⅝ of an inch
in diameter, but for beginners it is better to use larger stock to
allow for practice turning.
