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.
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.
