Tried posting vague route descriptions that focus on trail etiquette instead of exact locations. Slowed the rush way down while still getting people excited about the area. Sometimes less detail means better visitors.

Hand-lapping does give a great finish, but it's not always the best first step. For example, on softer metals, rough lapping can push grit into the surface. I saw this happen on an aluminum piece that got tiny scratches. Good cleaning before you start lapping helps prevent this. The smooth cycle is worth it, but only when you do it right.

Classic struggle! Manual feels real, automated scales.

My friend got a cat with six paws once.

Used to get annoyed when folks messed up simple tasks, figured they just weren't paying attention. Then my kid's fever med said "fill to the line" but the syringe had two different sets of markings. We under-dosed for a day before a nurse friend pointed it out. Now I see how often the guide itself is the issue. What's the worst instruction fail you've seen?
