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.

Their plans are delivered in a PDF format as part of a vlog series. They have regular episodes in the form of “seasons” and “episodes”. Your head will spin with the sheer number of “episodes” on the website. At the time of writing, it is at season 9, episode 933. A small caveat, though, is that you have to subscribe to their newsletter to download the free plans. No biggie. It’s just something to keep in mind.
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.)
