The drawers are very simple to make. First, cut the drawer bottoms from ½" plywood. Make them about 1/16" narrower than the distance between the dadoes and full length. Cut strips of solid wood or plywood equal to the inside depth of the drawers you want and cross-cut them to length. I assemble the drawers with glue and nails. Note that to store a 5" tall object, you don’t need a 5"-deep drawer – you just need 5" of headroom.
To the left of the cabinet hangs my table saw infeed support arms, my table saw spline jig, multifunction hold down jig, and a dry erase board I made several years ago for my wife. We never put it to use in the house so I put it in my shop. Below that is a rolling mechanics tool box. I store all of my wrenches, sockets, and tools of that nature in it.
Though our shops never seem to be spacious enough, how you store what’s inside can make the difference between a neat, organized work space and a disaster zone. The first priority is to have a good look at what’s in your shop and decide how often you use it. Things that you never use have no place in a tight shop. Items that you use only rarely or are overstock should be stored on a top shelf or in another room – not on the prime, easy-access shelves. I have laid claim to a few bays of shelving in our storage room. I store all my overstock hardware in full-extension pull-outs so I can find it easily when needed. In the storage room, I also store my benchtop tools that I use less frequently. All are fairly heavy, so I make sure to store them at about waist height to make it easy on my back.
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.)
