So when you’re finished cutting for the day, always release blade tension. With a positive rake angle and large, well-spaced teeth, a hook-tooth blade doesn’t clog easily. Shear Force – Made in the USA, the Shear Force blade is compatible with nearly every bandsaw. Keep the blade lubricated, no matter what material you are cutting. Use coarse tooth blades (2 or 3 TPI) for re-sawing and cutting thicker materials. Your email address will not be published. BLADE INSPECTION- Inspect the blade for cracks, dull teeth, rust and general damage every time you put it on the machine. Roland Johnson says a 3⁄8-in.-wide, 6-tpi hook-tooth blade, a 1⁄4-in., 10-tpi regular tooth blade, and a 1⁄2-in., 3-tpi hook-tooth blade are all you need in the shop. They also accept only narrow blades, often 1⁄2 " or less. If you cut wood of about 3/4″ thickness, use a 4TPI blade for a fast cut and 14 TPI for a slow cut but an infinitely smoother finish. BLADE CLEANING- Always clean the blade when you take it off the machine. The bend in the teeth creates a cut slightly wider than the thickness of the blade, which is important to prevent the blade from getting stuck from being pinched by the metal. The chart below, developed by Starrett®, offers guidelines for TPI selection based on material thickness. PITCH/TPI- The distance from the tip of one tooth to the tip of the next tooth. Thinner blades perform well for lighter work. Too much set results in too much air and not enough sawdust and can leave tooth marks. A blade in the 6 to 8 TPI range provides good general-purpose performance. Once you’ve set the tension according to manufacturer’s recommendations, the flutter test can help fine-tune it. So long time i find some information about the saw mill blade, now thank a lots to yr great post! Thickness of the blade required depends upon the diameter of the wheel and work to be done. Very good info. Order of procedures to prepare a blade; Teeth setting. Thick blades withstand more cutting strain from straight cuts but can break more easily from the bending and twisting action. This removes any manufacturing imperfections and prevents scouring of the thrust bearings and binding when cutting curves. When you take the blade off the machine or you are not going to use it for some time, it is recommended that you wax the blade. Generally, the larger the tooth, the coarser the cut, and the poorer the surface finish of the cut. There are certain indications if a blade has the correct pitch or if the pitch is too fine or too coarse. An alternate tooth set has one tooth going left, one going right, then left, right, etc. The smaller the tooth, the finer the cut and the better the surface finish of the cut. Bandsaw blades differ in thickness, width, length, and tooth configuration. The tooth and gullet are ground in one continuous process that greatly enhances the performance of the blade, giving a fast cut with a good surface finish to the wood. BEAM STRENGTH- This is the ability of the blade to resist bending backwards. This is not a rule, only a general guide. QUESTION: Would you recommend a hook tooth blade or a skip tooth blade (and what TPI) for resawing and why? Or keep reading to learn more about choosing and using bandsaw blades. Always release blade tension at the end of the day. The wax will coat the blade and will give a degree of protection against rust. The Resaw King is manufactured in Germany exclusively for LAGUNA and is perfected here, in the USA, by our skilled team of professionals using our full line of CNC machines. present in college.
