Day in and day out we all deal with electricity, but it seems to be some illusive concept that few woodworkers really understand. Electricity drives our tools, and drives our everyday life. Electricity has the versatility to replace many older forms of energy. Without it we would still be using lanterns for light, fires for heat, and oxen for work.
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.)
