Community guide

r/metalworking (#945, about 1.2 million) is for sharing metal projects, asking process questions and learning together—context-rich posts over bare phone snaps or company ads.

What belongs

Metalworking projects and questions (about 17 posts/day). Rules: behavioural guidelines; no company/self advertising spam; no low-effort lacking context; text questions and career advice norms.

Versus machining or welding-only rooms

Specialty trade subs go deep on one process. metalworking is the broader share-and-learn shop floor.

Practical pointers

Add process context to photos; skip company promo.
