Understanding the Distinctions Among Scroll Saw Blades: Application and Manufacturing Processes
Discover the key differences between various scroll saw blades, focusing on their specific applications and how they are manufactured to meet diverse woodworking needs.
Essential Insights into Scroll Saw Blades: Manufacturing Techniques and Optimal Usage
Gain in-depth knowledge about the construction of scroll saw blades, including their material composition, fabrication methods, and the ideal scenarios for their use to achieve precision and efficiency in your projects.
Pinned and Plain End Blades: Construction and Compatibility
Both pinned and plain end scroll saw blades are crafted from high-quality, pre-tempered high carbon steel. These blades are formed with either punched or milled teeth, which are shaped in regular or skip patterns, then meticulously set to facilitate smooth cutting. The pinning process is applied where necessary, and the blades are cut to specific lengths. Typically, these blades are characterized by their wider, thicker profiles with set teeth designed to create adequate clearance for the back of the blade, especially useful when navigating intricate curves. Historically, older scroll saw models such as the 24-inch Delta/Rockwell, Powermatic, as well as the Sprunger and Shop Smith, utilized loading or spring-actuated mechanisms requiring plain end blades. Although pin end blades remain popular in many modern, budget-friendly scroll saws, both types serve important roles depending on the saw’s mechanism and the task at hand.
Spiral and Metal Cutting Blades: Design and Versatile Applications
Spiral blades feature teeth that are uniformly shaped and are twisted around the blade to expose cutting edges in all directions. These teeth are predominantly milled, although in some cases, especially for jewelry or fine metalwork, they are shaped with precision files. Spiral blades are hardened and cooled after manufacturing, then cut to their specified lengths. Their unique design makes them exceptionally suitable for complex, multi-directional bends, offering unparalleled maneuverability. However, for straight cuts, using spiral blades might present some challenges due to their flexible orientation.
Precision Ground Tooth Blades: Superior Cutting Performance
Developed through advanced grinding technology by Olson Saw Company, these blades are made from pre-tempered high carbon steel. The teeth are ground twice to produce an ultra-sharp, finely honed edge along the entire tooth, face, and gullet of the blade. This meticulous grinding process results in blades that are free from tooth set and burs, allowing for exceptionally smooth cuts on straight lines and tight radii. They are cut to specific lengths at an angle that indicates the direction of the teeth, ensuring precision and consistency in every cut.
