Actually, a lot of woodworking is to pretty tight tolerances. One thousandth is light, two is heavy light, and woodworkers use light to tell when joinery is tight. We use tight tolerances, we just have different ways of measuring and achieving it.
A bucket or a barrel that isn't tight wouldn't be much use.
I cut two square joints, flip them to double any error, and see if there's light. The only way they'll get within a thousandth of an inch (light) is if the angles are both exactly ninety degrees. We used to call it "proving the saw".
