Resawing is the process of splitting 1 – 12 inch hardwood lumber or softwood lumber into two or more thinner pieces of full width and length boards. For example, splitting a ten-foot 2×4 into two, ten-foot 1x4s is considered resawing. As with all saws, resawing eliminates a blade’s width of material for each cut made. You may hear resawn softwood lumber referred to as “S3S”, or Surfaced 3 Sides, because it has one rough-sawn side that has not been surfaced as a standard softwood board of its size.
Resawn or 1×4 S3S, for example, is not exactly the same thickness or surface texture as standard 1×4 S4S, which has been surfaced on all 4 sides. Resawing material is often a great option for applications that require low cost and do not require a smooth surface on one side of the board.
In our Milwaukee mill, we have two high-speed McDonough re-saws and two, thin kerf Baker re-saws to offer the highest turnaround time without sacrificing quality.
