Methods and test cases
Calculators document units, formulas, rounding, grain or kerf assumptions, and known limitations. Important examples are checked against the same calculation functions used by the page.
Sources
Technical guidance prefers official measurement references, the USDA Wood Handbook, and current manufacturer instructions where equipment or material behavior controls.
Workshop limits
Outputs do not replace test cuts, machine calibration, workholding, guarding, material inspection, or a safe cutting sequence.
Editorial review
Review dates change only after substantive claims are checked. No public corrections channel is configured, so no contact identity is invented.
