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.
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.

These can cut 6" deep timber without any trouble and will resaw up to 12" deep but this would mean pushing maximum capacity. While these machines come with plenty of added features such as rack and pinion table tilt rack and pinion table tilt look for quick release blade tension levers. This is a very useful feature. It allows you to simply knock off the bandsaw to detension when you pack it in at the end of a long day and then swing it back to regain the same tension it was left at previously. This makes it much easier to properly maintain the machine. Woodworkers have so many options to choose from these days. Consider your present and future needs when deciding which bandsaw to buy. Saving money in the short term by buying too small a machine will cost you if you want to do quality work in the long run.
When it comes to using a portable sawmill your choice comes down to one of two options: either a bandsaw mill or a chainsaw mill. When considering a bandsaw you have to weigh all of the evidence to decide if it is the best choice for your needs. Bandsaw mills work by means of a blade sliding back and forth horizontally through the lumber. The denser the wood the harder it is for the blade to move. If a blade gets too slow or starts to bind then you wont have a precise cut. The blade has to fight to get through the wood and will start to bend slightly. Plus you run the risk of burning up the motor. The only way around this is to increase the power. Thats why it is better to invest in larger models of bandsaws. If you choose to continue using a bandsaw that is too small for the job then you could end up with wavy cut wood.
