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.
As is most things in woodworking it is a matter of measure twice and cut once. Remember that the left over sections of log can often be brought back to the bandsaw to made smaller bowls or squares. One of the great secrets in woodturning is the use of the bandsaw with its capability to make curved cuts easily and safely. In cutting green wood it is the use of a narrow band with wide spaced teeth that makes the cuts work. To get the best out of your bandsaw one must start with a properly adjusted blade guide blocks thrust bearings and a squared up table. It is very important to check each of these factors every time you use your saw change your blade or when your blade and blocks show some wear. A properly adjusted bandsaw is a delight to use. However if improperly adjusted it can be a major frustration. There are five simple steps one must perform in sequence to assure a properly tuned bandsaw. 1. Tension the Blade To do this you use the "blade tightening" knob that protrudes above the case of the top blade wheel. Some saws have indications for different blade widths.

The reason there is not a side load is the angle of the side of the tooth. The tooth is bent or set at such a sharp angle on the side that only the top corner of about.010 touches the wood fiber. Of course if you run your band excessively dull it does take on more side load. Now compare the gullet stretch per tooth. Remember both band bodies are .042. The set tooth has the total kerf stress divided between 3 teeth. The swaged full tooth carries the entire kerf stress per tooth plus the side load on 2 sides per tooth. It is easy to understand that the full tooth carries twice the load just because of the top width of .084. Then add the 2 sides of load and we have at least 3 times more tooth load per square inch than the set tooth bands have. What does this mean? From my experience the set tooth pound for pound will perform 2 to 3 times better than a full tooth of the same band width and thickness. This is true even if a special steel is welded to from the full tooth. Let me talk about the body of the band for a bit here. I have spoken of the distortion and how it changes the middle portion of the band to dish on the log side.
