For sometime now, I have wanted to do a modification on a Harbor Freight four or five drawer mechanic's tool cart. I saw a video online of a guy doing exactly what I wanted to do. So, when Harbor Freight recently put the carts on sale for 80 bucks off, I jumped on the deal and bought two of them. Below are the pictures of what they were as sold by HF and how they are now after the mod. To me, it just made sense because the space below the original top was a waste for storing tools or anything else.
