When you need to cut curves and unusual shapes into even the heaviest material, band saws offer unparalleled adaptability. However, using sharp band saw blades is the only way to guarantee the perforᴍᴀɴce of your band saw and the quality of your finished product. The best value can occasionally obtained by only sharpening an old blade rather than replacing it entirely, even though it makes sense to replace a dull blade with a new one most of the time. Before totally replacing your blade, you should normally be able to get two to three sharpenings out of it. You have two choices for sharpening your band saw blade: ᴍᴀɴually sharpen it yourself, or use a mechanical sharpening machine.
ᴍᴀɴually sharpen your blade
The sheer number of teeth on a band saw blade may make ᴍᴀɴual sharpening seem like an impossible operation, but if you don’t intend to sharpen blades frequently, it’s a much cheaper alternative to buying a mechanical sharpener. In other cases, such as when a blade strikes a nail or other foreign item, you will only be able to sharpen the dullest portions of the blade. However, there are times when you must get ready to sharpen the entire blade. These steps can be used to perform both partial and complete sharpenings.
You have the option of leaving the blade in the band saw or holding it while you sharpen using a homemade jig. Before you start, unplug the power if you plan to keep the blade in the saw. By pressing the sharpening stone up against the toothed edge, you may sharpen and align the tips of the teeth. Ensure that the stone is perpendicular to the saw table and parallel to the balde’s teeth.
As you ᴍᴀɴually advance the band saw backward, brush it against the teeth. Any projecting teeth will make contact with the stone as the blade moves and sharpen down. Run a file or a Dremel tool at a slight angle from the top of the tip to sharpen the back. The tool should be running at a low speed.
Find a file or Dremel attachment that fits the gap between the teeth and the gullet’s curve. Each tooth tip you want to sharpen should be lightly touched on the underside. To repair the cutting area, which is the outer edges of the gullet below the tip, use a round file or a Dremel bit. Inspect the gullet for any buildup of debris and clean it as necessary.
Using a motorized band saw blade sharpener will save you time and energy.
Although ᴍᴀɴual sharpening can help you save money, it’s frequently a laborious and stressful procedure. A sharpening machine could be a smart investment if you have a lot of extra saw blades that you want to utilize as much as possible. Specialized sharpeners greatly simplify the sharpening procedure, saving you time and effort that you may use elsewhere.
