Publisher and author of Woodshop Math · AUSV SYSTEMS PTY LTD, Victoria, Australia
AUSV Systems (AUSV SYSTEMS PTY LTD, ABN 14 696 099 751) is the company that publishes Woodshop Math. It writes and maintains every calculator, guide and project plan on this site from Victoria, Australia, and works on one narrow subject: the arithmetic and measurement conventions behind woodworking, carpentry and material takeoffs.
Areas of expertise
- Lumber and timber measurement conventions, including board feet, linear feet, nominal labels and dressed sizes
- Sheet-goods area estimating, cut-list planning and saw-kerf allowances
- Deck, fence, stair and roof layout geometry for early planning takeoffs
- Wood physical properties published by the USDA Forest Products Laboratory, including density and dimensional change
- Translating published standards and handbooks into calculators and project plans that state their own assumptions and limits
What we do not claim
AUSV Systems does not test products in a workshop, conduct field trials, provide structural engineering review or offer code-compliance authority. Project plans are calculated plans, not photographed builds. These limits are stated on every calculator, guide and plan.
