Saw a newcomer ask why we're "so strict" about the research-use-only line. Worth saying plainly: it isn't gatekeeping. Keeping the discussion to handling, testing, storage, and literature is what keeps the forum useful and keeps it open at all.
The moment a thread drifts into personal-use territory it stops being a research discussion and becomes something none of us are qualified to weigh in on. Different lane, different professionals. Here we talk benches and COAs.
