Sorry Ian but that’s bad advice. At least in the US, the general coverage of patents is the sole right to make, use, sell, or import.
35 U.S. Code § 271 - Infringement of patent
Except as otherwise provided in this title, whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent therefor, infringes the patent

Now is anyone going to do anything about a person making a single patented thing for themselves? Nah, there’s no damages. But it is an infringement.
