Informational workshop tools
The calculators and planning tools are offered free of charge for information and convenience. Outputs are estimates generated from the values you enter and the assumptions described on each tool page. They are not professional engineering, architectural, safety, legal, or purchasing advice.
Your responsibility
You are responsible for your measurements, material selection, machine setup, workholding, cutting sequence, personal protective equipment, and compliance with the instructions for your tools and materials. Independently verify important results before buying material, setting a machine, or making a cut.
Permitted use
You may use the site for lawful personal or commercial workshop planning. You may not interfere with the service, attempt to bypass security controls, use automated traffic that degrades availability, or misrepresent the site or its outputs as certified or endorsed.
No warranties
The service is provided “as is” and “as available,” without warranties of accuracy, completeness, availability, merchantability, fitness for a particular purpose, title, or non-infringement. Calculations, content, and availability can contain errors or change without notice. Some jurisdictions do not allow certain warranty exclusions, so those exclusions apply only to the extent permitted.
Limitation of liability
To the maximum extent permitted by law, the site operator will not be liable for indirect, incidental, special, consequential, or punitive loss, or for loss of material, work, revenue, data, or profit arising from use of or inability to use the service. Nothing in these terms excludes or limits liability or consumer rights that cannot lawfully be excluded or limited.
External services and links
Static files are delivered using third-party hosting infrastructure. Links to other sites, if present, are provided for convenience; their content and practices are outside this site’s control.
Changes and availability
Tools may be corrected, changed, suspended, or discontinued. These terms may be revised, with the effective date updated on this page. Continued use after a revision means you accept the revised terms.
