Here's some pictures of the toolbox that I've been working on for about the last month. I'm an aircraft mechanic and I've always enjoyed building things out of steel. Some of you might ask why build a toolbox when you can just buy one? I've looked at many of tool boxes at many different places many of which now are either plastic or very thin sheet metal. The plastic ones just don't hold up to the abuse that I seem to put my box through. The steel ones aren't much different in terms of quality. That's mostly the reason why I decided to build my own box, build it with some quality. The bottom piece of steel is the thickest piece in the box. Its 14 gauge sheet metal since it will see most of the abuse getting dropped and slid across concrete. The rest of the box is all 18 gauge sheet metal. I could of gone thicker but I'm trying to keep the weight in check as well. The goals for this project are to build a box that is stronger, better quality, and to last longer than my previous tool boxes. So here's that it all started with some steel I had in my garage. The bottom and two sides. Bend the two side panel at each corner. Added the back and one of the top tray supports. Front of the box, this piece has to be longer and bent to conform to the lid when it is closed. Made the first two bends on the front piece to clear the lid. I don't have a sheet metal brake so all of this is done with 2 piece of 90 angle iron, hammers and c-clamps. You can see them on my work bench Making one more 90 degree bend. The last of four bends in the front panel. This was one of the hardest pieces to make with what I had available. Test fitting panels, this is one of those measure four times cut and trim once. All of the bottom of the box done. No welding had been done yet. I only tacked a few corners to hold things in place.
