Sounds like a solid plan. First we pick a strong hardwood, like oak or maple, for the frame. Then we build a simple box with thick ribs and a sturdy top that can take a weighty latch. For the lock, we’ll slot a metal plate inside the lid so the bolt can slide straight through. Add a bit of metal reinforcement on the corners to keep the frame from warping. When we finish, the chest will hold all the tools tight and keep the floor clear. Let me know the dimensions you’re thinking, and we’ll sketch a quick layout.

Got the size, the ribs and the top plate locked in. 48 by 24 by 24, 1.5‑inch ribs, half‑inch plate on the lid. I’ll cut the main panels first, then build the ribs with a 1/4‑in cross brace at each corner for extra stiffness. The metal brackets will go inside the corner joints to keep the corners tight. For the lock, I’ll cut a slot in the top plate that lines up with the latch bolt, so the latch stays flush when closed. The edges will be sanded and sealed with a clear finish to protect the wood. I’ll draw a quick layout and send it over so you can double‑check the dimensions before we start cutting. Let's get the saw rolling.
