Was simple for a pipe fitter, construction worker to assemble BUT mine was lacking all of the hardware that was needed.And once the old newspapers and cut-up cardboard boxes were set on fire and settled down, I could see that the pieces used to form the bottom, had pulled out of their slowed position. So I'm going to have to get some thicker material and fabricate a better grated bottom because apparently the heat caused the sides to expand pulled the bottom (floor) apart. Just a few small things that can be re-done easily, but it should have been designed better and these problems thought out.So good luck.
