It is only when the prescribed amount is exceeded that it becomes distorted and loses strength. Think of valve springs in a gas/diesel engine. They operate within their ability to extend compress and return every time and run almost forever under harsh conditions. They do not exceed their steels ability to stretch and return. A good understanding of the above two paragraphs is very important to understand an accurate comparison between the swage tooth band and the set tooth that we will discuss below. Now let us look at a set tooth band of .042 thickness: The Kerf of a set tooth band is also two times the thickness. Usually .084 (sometimes more sometimes less). The difference is the set tooth shares the tooth load between 3 teeth. Each tooth is only .042 on the top or the leading edge. The most any tooth can cut is.042 wide. The average that the 3 teeth cut is only .028. The right and left tooth only cut the set amount beyond the body width. Only 2 of the teeth cut on the side and they only have 1 side to create side load which is very minimum. It is so small that I do not consider it to have a side load.
It is my opinion that a good set tooth band with correct curvature that is 1-1/2 wide will outperform dollar for yield a band twice the width at 3 inches that has a full tooth. It is easier to keep the tooth load down on a set tooth band and it is easier to maintain a set tooth band. Full tooth bands require a lot of attention because of the larger tooth load. They require more professional attention. This Professional attention is at a large expense. Want to understand why many people are still big believers in bandsaw mills? Lets explore the subject. In the past do-it-yourselfers who were unsatisfied with the lumber they found at the big box stores or their local sawmill would have had few options. However those days are gone. These days its possible to find a portable sawmill that you can set up and work yourself. But with over 200 companies currently offering these mills how do you find the one that best fits your needs? The right mill for you will depend on how much milling you intend to do and will take into consideration such things as the size of the logs. Also running a portable sawmill is a demanding job and youll need to consider how much effort from you is required to run the machine.

A board with one square edge and side is necessary. Problem is most woodworkers dont have a clue how to do this. Successful resawing calls for nothing more complicated than appropriate blade selection adequate tension setting the fence and proper stock control. Blade Selection: As you saw through very thick stock you put a lot of pressure on every part of the blade engaged in the cut. Each saw tooth shaves out waste. Blades with 3 teeth per inch (tpi) have large gullets which have room for a lot of waste. Thrust bearings support the blade above and below. During the actual cut only the blades stiffness or "beam strength" will keep the cut proceeding straight and free of wander. Its my experience that a quality 1/2" 3-tooth blade gives good results. I tried wider blades with no increase in efficiency.
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.
