Sawmill recovery rate

Question It looks like bandsaw mills have a higher recovery rate than circular mills do My reasoning is that if you are buying logs by the board foot and are being paid by the board foot you would get more board footage with a bandsaw mill which means you would make more money plus you may get overrun more footage of lumber than what you bought the logs for Get price
