Wait, your library actually gives out free bingo sheets?

My buddy rented a rock auger for his yard project last spring. That thing just bounced right off the caliche layer under his dirt. Sounded like a jackhammer hitting a sidewalk. He ended up calling a guy with a mini excavator, who said it was like digging through concrete. Total nightmare.

Manufacturers get basic stuff wrong all the time. My new extension cord came out of the box with a permanent loop in it.

You found a rotten joist? That's way past a simple floorboard fix. I would have lost my mind dealing with that much hidden damage.

Honestly, that study is probably understating it. The real danger with those old forges is the buildup over time, not just the peak reading. 120 ppm is already in the headache and nausea zone. You need active ventilation, not just a cracked window. A simple box fan in the door blowing out can make a huge difference. I'd also check for leaks in the forge itself, like cracks in the firepot or a bad seal on the air intake.
