It's wild how many things we just do because it's the way we've always seen it done. You see this with cleaning products too, mixing stuff in random containers that really shouldn't be mixed. It's a scary reminder that common practice isn't always safe practice, and sometimes you get lucky for years before it goes wrong.

amy_coleman saying it was just a weird one-off with a burr is wild to me. That bracket flew 15 feet and dented the steel cabinet door. If you're running 50 parts, the setup has to hold for all 50, not 49. The manual specs are for the vise itself, not your specific cut on a specific material. I watched a guy snap a 3/4 end mill because his steel part slipped in a vise set for aluminum. It's not overkill, it's just the job.

Oh man, we learned to pick one huge book a year, max.
