Estimates only

Calculators give reference values and estimates for information. They are not financial, investment, tax or legal advice, and not a quotation to buy or sell.

Market data

Metal prices and exchange rates come from third parties and are stored as reference snapshots. Each value shows its source and quote time, and a warning when it is out of date. They are not real-time trading prices and not dealer or local-market prices.

Design files

Files are provided under the licence on each design page. Test fit on scrap, follow your machine’s safety guidance and wear the protective equipment it requires.

Reliance

We are not responsible for losses that result from relying on a result without independent verification.
