Remember the term certain distance this is important. Each molecule of steel is round in shape and can be stretched or elongated to a certain distance before it is stressed and begins to remain elongated. When a molecule remains elongated it has been distorted in the gullet from pulling too large (more than the body molecules can take) of a tooth load. The band gullet has what we call a long front. We say this because the front has stretched but the molecules at the back of the band have remained un stretched. This condition causes a hump that rises up in the middle portion of the band or in other words the middle of the band will hump toward the slab side and the mirror image is on the log side being concave. At this point the band will dive into the log every time! Note: A good spring has the ability to elongate or compress a certain or prescribed amount and return to its original shape millions of times without losing strength.

Or better yet ask other woodcraft enthusiasts on their take on their power cutting tool of choice to know their first hand experience in using them. Many people ask me about wide cut blades. What are the advantages and disadvantages of using wide cut blades. I have had a good amount of experience with bands up to 12" wide but for this particular article we will deal with the most popular applications and that is blades in the 2"-6" width. Lets start with the tooth of the bandsaw blades: We know that tooth load is very important with all bandsaw blades and keeping tooth load down per square inch is the most important thing that a sawyer/sawfiler can do to preserve his bandsaw. For an illustration of this lets look at the teeth of a swage tooth or a welded tooth band. Note that all comparisons will have to be made of equal width bands for this comparison to be accurate. The swage tooth and the welded tooth have a full tooth width at the top or the leading edge.
Next to release the blade loosen each set of the bandsaws blade guides. Making enough space to allow for the simplest reinstallation of your new blade loosen the upper ball bearing guide and the upper block guides. Block guides must be loosened at all four directions - left-right and forward-back. Following this additionally loosen the lower blade guides beneath the saw table. Each blade guide has an adjustment knob to make this step a bit simpler. Next using the tension wheel (knob) release the tension on the blade. Once tension is adequately released you should be able to slide the blade safely from the blade-wheel through the slot in the saw table. Carefully recoil the blade and tie it off to prevent the thing from becoming an explosive blade disaster. Making Friends With Your New Blade: Opening your new bandsaw blade can also become an explosive blade disaster.
