bandsaw mill blade guides
A bandsaw blade has to be matched to the job in hand and to a lesser extent to the size of the bandsaw. You would not try to rip a 2" board with a tenon saw nor crosscut plywood with a greenwood saw. You would select the right blade for the job and the same is true for a bandsaw. Just because the machine is powered does not mean that one blade will cut everything it wont. So we need a selection of blades dependent on what we are doing. Fortunately despite there being a vast array of blades to choose from we can do 99% of our normal work with just two or three different blades. Blade width Given that the challenge with a bandsaw is to get it to cut straight it is easy to think that the wider the blade the better and to a certain extent this is true. You are likely to get better results with a ½" or ¾" blade than a ¼" one. But the temptation is to go as wide as the wheels will take. Which is an inch or more.
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.

With a number of bandsaw models now available in the market it is quite difficult to find the right bandsaw to meet your requirements you often find bandsaws that look alike but vary greatly in price. Some bandsaws may be made in the same factory but have different features. Base models may be the same but some of the upgrades may be different. Getting to the depth of the matter Woodworkers must remember that while choosing a bandsaw it is important not to look only at outward appearances but compare the details. Ask the dealer questions and make an informed decision based on the quality features and reliability of the machine. Also make sure you attach a value to every feature you want to consider and the tasks that you need to perform whether immediate or in the long run.
This is why there is a time-tested and woodworker-specialized method for safely uncoiling your bandsaw blades. Said method is as follows: throw the blade on the ground. Well more specifically if your blade is packaged or tied carefully unpackage or untie it while maintaining its coil. With a firm grip on the blade throw it away from your body and into an open space. The blade will violently uncoil and fall to the floor from where you can peacefully collect it. You may also wear gloves during this process - they will eliminate the possibility of cut hands and fingers. Installing Your New Blade: Thread the new blade back through the slots on the saw table and situate the blade around and running through the center of the upper and lower blade-wheels.
