How these guides are written

Who writes them

Ryan writes every guide on this site. There is no content agency, no rewritten competitor article and no guest post bought for a backlink. Where a guide draws on a published standard, the standard is named in the text so you can check it yourself.

Numbers are typical, never promised

Every tolerance, lead time and cost figure on this site is a planning figure: what shops here hold routinely on the right machine, in reasonable material, with a competent operator. None of it is a commitment on your part, and no figure here overrides what a shop puts in its own quote. Where a range is wide, the guide says so rather than picking a comfortable middle.

What we will not publish

• Client counts, network size, years in business or any other number we cannot evidence
• Certifications, ours or anyone else's, unless the certificate has been seen
• Testimonials, case studies or customer names that have not been approved in writing
• Factory photographs that are not ours to publish
• Named criticism of a specific shop, a competitor or another country
• Anything written to please a search engine that would waste a reader's time

Where our interest lies, stated plainly

We are paid by machine shops for the briefs they choose to take, and never by buyers. That gives us an interest in you sending a well prepared request, which is why so many guides here are about preparing one. It gives us no interest in which shop wins your order, because the fee is the same either way, and no interest in telling you Vietnam is right for your part when it is not, because a badly matched request becomes a brief nobody takes.

Where a guide touches something we sell, it says so in the text rather than pretending to be neutral.

How guides are kept current

Material availability, lead times and what shops routinely hold all move. Guides carry a publication date, and a checked date once they have been reviewed. A guide that is materially wrong gets corrected rather than quietly deleted, and a correction that changes the advice is noted at the point it applies.

Sending a correction

If something here is wrong, write to sales at vncnc.com with the page and what is incorrect. Corrections from machinists, inspectors and buyers who have actually run the part are the most useful mail we get, and they are acted on within 24 business hours. You do not need to be a customer, and we will not ask you to become one.

Reusing this material

Quote from these guides, screenshot the tables and use the templates in your own documents. A link back is appreciated and not required. The reference pages in particular exist to be copied into other people's processes, which is the entire point of publishing them.
