Worry leaving mine alone that long would grow mold. Had it happen once when my kitchen got too warm. What temp was your pantry at?

Wait, you let it smell your tools first?

Balancing counterweights is one of those jobs that seems simple until you're deep in it. My cousin had a classic muscle car that would shake at high speeds, and we blamed everything from the tires to the fuel mix. Turned out it was a tiny off-balance in the driveshaft, something we overlooked for months. We fixed it with some makeshift weights from a hardware store, and now it purrs like a kitten. Really makes you appreciate how precise engineering needs to be.
