Which statement best describes stock inspection before layout?

• A. Always assume nominal sizes.
• B. Inspect stock for knots, warping, and splits before layout to ensure accuracy.
• C. Measurement errors are acceptable.
• D. Only inspect stock after assembly.

Answer: (B)

Before layout, you need to verify the actual condition and size of the stock to ensure the parts you cut will fit correctly. Knots, warping, and splits can throw off straight edges and precise thickness, leading to inaccurate cuts and weak joints if you don’t catch them first. By inspecting the stock upfront, you can select the best pieces, orient them to minimize waste and movement, and either re-saw or trim out defects so your layout reflects true dimensions. This step helps maintain consistent results and reduces the risk of surprises later in the project.

Choosing to assume nominal sizes isn’t reliable because real stock varies in thickness and width after milling and drying. Claiming measurement errors are acceptable isn’t appropriate when precision is needed for good fits. Waiting to inspect after assembly defeats the purpose of layout, which relies on accurate stock dimensions and condition from the start.
