Historically I’ve been beholden to the lumber retailer for whatever thickness he had available. That usually meant 4/4 rough sawn or 3/4 S4S. That’s rather stout for smaller scale projects and planing half of it away seemed a terrible waste of time, money, and good lumber. Dimension lumber in 1/4 and 3/8 thicknesses was stupid expensive and rarely straight.
Since I acquired my Rikon bandsaw this past summer, I’ve been experimenting with resawing. What a game changer. I’ve resawn 4/4 and 3/4 stock so far and had excellent results both times. I enjoy making boxes and other smaller scale projects, and the thinner stock is much easier to work with and more appropriate for scale. Bookmatching and grain wrapping is simple. Lumber just got much more economical too.
