On a band sawkeep a few different thickness blades, making your choice depending on the sharpness of the curves being cut. The larger the tooth, the faster the cut, because the tooth has band saw tpi for wood waste large gullet and has a greater capacity to transport large amounts of sawdust through the job. So before you bring the lateral guides and thrust bearings up close to the blade, close the wheel covers, plug in the saw and turn it on. Easy Resawing It is easier to resaw with a bandsaw tool than a band saw tpi for wood waste saw because the blade has woof cut less and the saw kerfs keep it from wandering. The valleys between the teeth on any blade are called the gullets. Resawing After the setup is complete, now you can start resawing.

Fit the jig to your saw, modifying the cleats as necessary. Make your blanks about 1-in. The notch creates a pocket for the blade to start in, and should be centered on the width of the blank Photo 2b. Sources Note: Product availability and prices are subject to change. McFeeleys , , Threaded inserts for jigs. Mount this adjustable circle jig to your saw table. It has an adjustable dovetailed slider, and a screw for a pivot point. The pivot point must be lined up with the front of the saw blade.

Spin the blank to cut a perfect circle. If the blade wanders even with a slow feed rate, check the position of the pivot point. It probably needs front to back adjustment. Woodcarvers use this technique to rough out carving blanks and furniture builders use it to cut cabriole legs. Trace your pattern on two adjacent faces.

Cut all the lines on one face, keeping the offcut pieces. Then use masking tape to reassemble the block. See AW 61, p. If you only need to resaw a board or two, a single-point fence is the way to go. First, get a good resaw blade for your saw. I use the biggest blade the saw will take. Set the fence on your bandsaw table and be sure the dowel and blade are parallel vertically.

The crown of the dowel must be slightly in front of the teeth of the blade. Set the distance from the dowel to the blade to the amount you want to resaw. Securely clamp the fence. Steer the board through the resaw fence, cutting on your marked line. The board should only contact the dowel. Keep your eye on the face of the board too. It should stay tight against the dowel. To keep my hands away from the blade, I pull the last 6 in.

Adjust the tracking. With your saw unplugged, back off the guide blocks and thrust bearings as far as possible. Put the blade on, and set the tension according to the settings on the saw. Then, use the tracking adjustment knob to correctly set the upper wheel. Turning the upper wheel by hand, adjust for proper tracking. For larger blades, center the blade on the tire. The valleys between the teeth on any blade are called the gullets. Bring the guide blocks forward until the fronts of the blocks are even with the bottoms of the bandsaw blade gullets.

Again, typing paper will work as a feeler gauge. Turn the blade a few rotations by hand to make sure nothing is rubbing. Make sure the tension is right. I check it by doing a test resaw in a 5-in. Just go in a few inches, taking it easy on the feed rate. Turn out of the cut. If not, apply a little more tension and test again. Minimum horsepower is required. The blade makes quality cuts for a long period. There is excessive heat, causing premature breakage or rapid dulling.

Unnecessarily high feeding pressure is required. Unnecessarily high horsepower is required. The blade wears excessively. The teeth wear excessively. The band saw or blade vibrates. The thicker the band, the greater the tendency for the blade to break due to stress cracking, and the larger the bandsaw wheels have to be. If your blade is too thick for your wheel diameter, it will crack. The harder the material, the finer the pitch that is required.

For example, exotic hard woods such as ebony and rosewood require blades with a finer pitch than hard woods such as oak or maple. Soft wood such as pine will quickly clog the blade and decrease its ability to cut. Having a variety of tooth configurations in the same width will most likely give you an acceptable choice for a particular job. The Resaw King will cut most woods, but it must be noted that when cutting woods with a high silicon content or very hard woods such as iron wood, ebony, etc.

KERF- The width of the saw cut. The larger the kerf, the smaller the radius that can be cut. But the greater the amount of wood that the blade has to cut and the greater the horsepower that is needed, as the blade is doing more work. The greater the kerf, the larger the amount of wood that is being wasted by the cut. The greater the angle, the more aggressive the tooth, and the faster the cut.

But the faster the cut, the faster the tooth will blunt, and the poorer the surface finish of the cut. Aggressive blades are suitable for soft woods but will not last when cutting hard woods.

The smaller the angle, the less aggressive the tooth, the slower the cut, and the harder the wood that the blade is suitable to cut.

Hook teeth have a progressive cutting angle and take the form of a progressive radius. They are used for fast cutting where finish is not important. Rake teeth have a flat cutting angle and are used for fine surface finish of the cut. The Resaw King has a rake tooth form.

The tooth and gullet are ground in one continuous process that greatly enhances the performance of the blade, giving a fast cut with a good surface finish to the wood.

The larger the tooth pitch , the bigger the gullet. The greater the angle, the more aggressive the tooth, but the weaker the tooth. If you leave it gummy or with wood in the gullets, the blade will rust. Rust is the enemy of the woodworker. When you take the blade off the machine or you are not going to use it for some time, it is recommended that you wax the blade. Have a rag that is impregnated with wax that you pull the blade through backward.

The wax will coat the blade and will give a degree of protection against rust. Never use a dull or damaged blade; they are dangerous. If your blade is dull, have it re-sharpened or replace it. One method is to store each blade on a hook with the teeth against a wall. Nail cardboard or a wood sheet on to the wall so that the teeth are protected from damage, and if you brush against the blade it will not cause injury. Please note: Your bandsaw blade length and width parameters can be located on the back of your saw on a plate above the motor.

Please refer to your bandsaw for blade length.
