In my machine shop, I store my thickness planer under the infeed table of my jointer. The feed direction of the planer is one direction and the jointer the other. This works especially well because I can joint all my boards and stack them on a cart or sawhorses; then, without reorienting them, I can feed them through the planer (after I pull it out, of course).
What is the one thing every woodworker needs? Yes, a workbench. Now that you have or at least I am assuming you have worked on so many woodworking projects, you are close to becoming a professional woodworker. You now probably owe yourself a nice woodworking bench. You should also know that a true woodworker never buys his bench from the market, but always builds one himself. But before you start this project, you should know what a workbench is.
Drawers are really useful in a wood shop – you can’t have enough. They keep out the dust and with dividers or compartments they can help organize as well. A drawer that is too deep ends up getting filled with anything that fits and becomes a junk drawer, so multiple shallow drawers are better than one deep drawer. However, drawer slides can be expensive so I make my own drawers with built-in drawer slides. In addition to saving costs, if I make multiple cabinets the same width, I can move drawers from one cabinet to another quickly and easily.
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.)
