Yes this is absolutely my approach.I guess the main point here is to start making stuff. As time goes on, you'll accumulate more tools. I started out with a saber saw, belt sander, drill, and a router, all from 1970s Sears. With a birch plywood straightedge and a few clamps, I built all sorts of stuff out of shelving pine. Thank goodness, most of it didn't survive over the decades.
I imagine I'm going to make a whole bunch of crooked boxes
