There’s nine more drawers that I didn’t take interior pictures of because it’s just generic stuff. But I will go through the contents for you. Top to bottom in the left column is a drawer for manuals, a drawer for every letter that I have received from all of you out there, and a drawer for my electrical tools and supplies. Top to bottom in the center column is a drawer for miscellaneous hand tools that are more general household and carpentry related such as pry bars, putty knives, and drywall tools, a drawer for hammers, mallets and squares, and a drawer for all of my hand held cutting tools like handsaws, knives, and chisels. Top to bottom in the third column is a drawer for all types of brushes, a drawer for all of my sanding tools and supplies, and a drawer for all of my router bits and attachments.
Cut off a 21-in.-long board for the shelves, rip it in the middle to make two shelves, and cut 45-degree bevels on the two long front edges with a router or table saw. Bevel the ends of the other board, cut dadoes, which are grooves cut into the wood with a router or a table saw with a dado blade, cross- wise (cut a dado on scrap and test-fit the shelves first!) and cut it into four narrower boards, two at 1-3/8 in. wide and two at 4 in.
You can also use Google image search to research a project. Unlike the PDF search, the image search provides a photo of what the project will look like, which is helpful in determining if you want to pursue building it. By doing an image search for how to build a step stool, you will have a ton of options that all lead to woodworking plans of various quality. (The how to part of these is important—otherwise you’ll just get pictures of step stools.)
