If a glossary entry left you with a follow-up question, or a tolerance chart still reads like a foreign document, there are two honest routes: write to the editors directly, or check the reference shelf first. No account, no queue ticket, no promised reply window.
Questions about a term, a correction to a chart walkthrough, or a build log you want considered all go to the same place. A message reaches the site handler and lands with whoever is editing that week.
Many questions are already answered on the reference shelf. Worth a look first:
If a term is still unclear, say so in your message. Glossary entries grow out of exactly those questions.
A few things worth knowing about how the Learn entries work, what they assume, and where they stop. Nothing here is a course, a qualification or a promise about your machine.
You already have a bench, a vice and a way to measure. The glossary and explainers start from there and skip the beginner tool-shopping talk, because that sits on the blog pages instead.
Have the part, the drawing or the offcut next to you while you read. Terms like runout, tolerance band and fence squareness only click when you can check them against something on the bench.
Entries are short on purpose. A tolerance walkthrough takes a few minutes to read and longer to try. There is no schedule to follow and no order you have to work through.
A home bench cannot verify every figure a chart asks for. The entries say where that line falls rather than pretending a garage setup can hold a tolerance it cannot measure.
No certificates, no graded exercises and no formal qualification. The glossary grows as readers ask about terms, and corrections are welcome when a definition reads wrong at the bench.
Nothing here replaces a metrology course or a machine manual. Treat each entry as bench notes from people who ran the same setup, not as an authority on your specific equipment.
If a term is missing or a definition does not match what you see on your own bench, the contact page is where corrections and reader questions land. How submissions are handled is set out in the privacy policy.
Questions about a glossary entry, a correction to a tolerance walkthrough, or a build log you want considered for the Learn shelf all land in the same place. Write to the address below and it reaches the editor handling that strand of the journal.
If your note is about a specific entry, mention the term or the post title. It saves a round of back-and-forth and keeps the reply on the bench rather than in generalities.
