With all the pieces perfectly cut on the MultiCam CNC plasma it was a snap to fit them together, tack everything in place to align all the pieces and then weld things up solid.
Once everything was welded it was time for some serious grinding and polishing. It is now a serious and heavy duty box.
Once the grinding was done and the lid was fit I sprayed on the reacting acid and watched the rust begin to form instantly. A few hours later the whole piece had a beautiful patina. Now it is time to begin the fun stuff that fits inside!
