Terms

CutCalc is a free set of woodworking calculators. Using the site means you accept these terms. If you do not, do not use the site.

Estimates

Results are arithmetic from the inputs and the model described on that page. They are planning numbers. They are not a measurement of your board, not a quote from a lumber yard, and not a certificate that a joint, a stair, a shelf, a railing, or a finish is safe or legal.

Saw settings need a test cut. Walls are often out of square. Slide clearances come from the slide maker. Moisture coefficients apply inside the band the source describes. A sheet drawing is a shelf layout, not proof that the parts will fall out of the saw in that order.

Your tools

Follow the instructions that came with the saw, the blade, the finish, and the slide. The site does not tell you to remove a guard or to ignore a label. You are responsible for the cut you make.

No warranty

The site is provided as is. To the extent the law allows, there is no warranty of accuracy, fitness for a particular project, or uninterrupted availability. To the extent the law allows, the operator is not liable for lost material, lost time, or injury from relying on a result. Some jurisdictions do not allow those limits, and in that case the limit applies only as far as the law allows.

Advertising

If advertising is turned on, the slots are labeled and load only after the choice described in the privacy page. Do not click ads on your own site if you are the operator. The ad program’s rules, not these terms, decide whether an account is approved or paid.

The pages

You may use the calculators for your own work. You may not copy the pages into another site and present them as your own, and you may not scrape them to mint a pile of thin pages. The Wood Handbook coefficients are facts from a U.S. government publication. The writing around them is the site’s.

Law

These terms are a plain statement of how CutCalc is offered. They are not a substitute for advice from a lawyer if you have a dispute.

Changes

The date at the top changes when these terms change. Continuing to use the site after that date means you accept the new terms.
