I'm a beginner looking to build my first tool chest similar to a design I found online. I currently have a workbench on my parents' back patio and keep my tools stored in the garage. I'm considering keeping the tool chest outside on the patio, which is sheltered from rain and direct sunlight, but I live in North Texas where humidity can be a problem. I usually oil my tools and intend to place camphor inside the chest to prevent rust. Would this setup work, or will I face issues with moisture and condensation? I'd prefer not to move the chest back to the garage every time I want to work, as the patio is quite a distance from the garage.

I know some folks who keep their tools in sheds and barns—while their tools tend to be rustier than mine, they remain usable. My worry would be that the box might not handle temperature changes well, leading to condensation. Maybe try a small experiment first: grab a little box, toss an iron tool in there, and see what happens before you fully commit.
Humidity itself isn’t necessarily the issue; it’s the moisture that builds up during temperature shifts. If you're leaving it outside, make sure it’s fully sealed and throw in some reusable desiccant packets. Also, considering some wheels could help with making it portable, just in case!
Absolutely, you can store the tool chest outdoors, but make sure to weatherproof it. I’d recommend using marine-grade paint for the finish, adding raised feet or casters to protect against ground moisture, and using weather stripping around the lid to keep moisture out. You might even want to caulk the seams for extra security!

Thanks for the tip about the desiccant! I’ll definitely look into that.
