This is kind of a weird video, more content than instruction. It's a lot of unnecessary effort to put into shop furniture: like using sliding dovetails and sanding the top. Then you're left with a product that is less easy to use than a belt sander (try changing belts, what's the grit?) and takes up a massive amount of space (which makes sense if you have two garages.) I mean, it's fun to see kids experimenting, but if you're creating content think about what your audience needs or wants to watch.
