One buddy clamped his laser to the form and it fell right into the wet concrete.

What kind of stuff have you broken trying to cram it in? Was it a plate that shattered or something else?

Man I can barely sand anything right so I'll take all the help I can get.

Hold on though. Is it really that deep? It's a tool, not a time capsule. You're acting like it's going to sit in your garage and watch you slowly fade away. Worst case it gets banged up, loses a drawer, and ends up at a garage sale for twenty bucks. I'd be more worried about my knees or my back outlasting me, not a toolbox. Maybe I'm just not sentimental about metal drawers.

My three bedroom basement took almost four months to stop feeling like a walk in fridge after we moved in. The dehumidifier ran nonstop for the first two months and I still had to wipe down the walls every week. It dried out my old book collection and a couple of wooden frames got cracks in them. Ngl, basements are just hard to keep balanced no matter what you do down there.
