That six-finger thing is a known training data issue, not copying.

My uncle's 1920s craftsman had a floor so out of level we used a laser. Still took a full day to shim and scribe for a single threshold. Old houses fight back.

Wait you're running a COAL forge in a SUBURBAN garage? That's wild, the smoke and smell must be insane. Propane was the only real choice for me with neighbors that close. The cost hurts at first but not setting off every smoke alarm in the house is worth it. You really have to miss that dirty, hands-on feel to even think about going back.

Hold up, @robert_jones, I gotta push back on that. The right gear isn't about overcomplicating things, it's about doing the job better and faster. Sure, pure skill with basic tools can work, but good tools make hard tasks easier and let you do things basics just can't. It's like saying a master chef only needs a dull knife. They could manage, but why would they? Better tools let skilled people reach another level.

What about the stuff you can't even see messing things up? I've heard of people using tap water for a soak and the minerals in it leaving a crust that ruins delicate surfaces. @mark_nguyen95's spot test is smart, but you also need to think about what's in your cleaning water. For really fragile organic stuff like that sandal, even the wrong water pH can cause damage over time. It's not just the brush, it's everything that touches the find.
