Recovery rate is not the most important factor in a production mill setup When I ran a circle blade we would saw a lot of 12 to 14 inch logs into cross ties and get 4 boards off the sid My band mill does no better other than the fact that I can take a bit more time and often get a better board and trim a bit better
