THE PRACTICAL WOODSHOP

Make morefrom every length.

Turn a pile of timber and a parts list into a cutting plan you can actually read. Include your saw kerf, use the stock you have, and take the plan to the bench.

Three greedy layouts are compared. This is a practical suggested plan; the fewest possible bars are not guaranteed.

Planning precision: 0.000001 mm internally. Bars are drawn to a common length scale; the diagram is not a physical cutting template.

A plan you can check.

The numbers, and the reasoning.

Every estimate includes the assumptions behind it. Check your stock and final measurements before making a cut.

  1. 01

    Start with real stock

    One material and cross-section per plan. Add a separate row for each stock length.

  2. 02

    Make room for the blade

    One 1,000 mm bar can produce 600 mm and 397 mm pieces with a 3 mm kerf and no end trim. A 600 mm + 400 mm pair does not fit once the kerf is included.

  3. 03

    Take it to the bench

    Print the plan with its measurements, or export a CSV to continue in a spreadsheet.
