Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Classifieds/sales/ads by retailers/manufacturers must go in the Buy/Sell/Trade megathread; job posts need pay and direct company affiliation.
Links
Links are prohibited in posts or comments. Name things in plain text; interested readers will search.
What this community rewards
Dominant post formats: showcase, question, guide
Headline: specific + part/machine and operation (e.g., “Bridgeport jig for 1/8" slots”). Write in first person, include clear photos, machine/tool specs, feeds/speeds and steps; short, practical text (a few short paragraphs). Tone: humble, helpful, technical. What wins: detailed builds, troubleshooting questions, useful how‑tos. What gets removed/downvoted: overt sales, affiliate links, surveys, AI content, political posts.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked July 2026. Rules change and moderators have the final say: verify at r/machinists's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
