Pallet Resaws and Portable Sawmills
Good cutting depends on many variables. So many, that each situation may need a unique solution. We are available to help you choose the right blade for the right applications and diagnose problems that might exist with your cutting process. Our customer base uses the whole spectrum of machines and cuts all kinds of materials. Together we can identify a solution for you.
General Cutting Principles
Eight Teeth in the Cut: A starting point to determine the teeth configuration for your wood cutting application is to have eight teeth in the cut. For example, if you primarily resaw four inches wide you may want to use a 2TPI blade. Six inch resawing should use a ¾ inch pitch (1.3TPI) blade. A popular tooth pattern for portable sawmill cutting is a 7/8 inch pitch (1.1TPI). This seems to be a happy medium for entering the log while being able to cut in the center of the log as well.
Heat is the number one contributor to blade failure. Heat causes the blade to prematurely fatigue. Sources of heat come from the teeth while cutting, blade rubbing on guides and back-up supports as well as blade body wear on the wood itself. Sharp teeth minimize heat from the cutting. Properly spaced guides, a well tracking blade, and good wheel conditions (wheel surface, balance, and alignment) help to minimize heat to the body. Properly set blades and efficient saw dust removal minimizes the heat from body to wood friction. Fluids designed to keep the blade clean and free from residue build-up on the body help to minimize body to wood friction as well.
