A band saw is used to cut irregular shapes and to cut curves. It can cut through thick lumber and to rip lumber and to make crosscuts out of short pieces. Ripping lumber is to cut thin slabs out of wood, which is also called as resawing. Various blades are used according to the need of the cut. Smooth cuts can be made in wood as well as in other metals. The band consists of a rotating blade that is supported by three wheels and a motor to run the machine. The motor helps to run the blade. There are various models of band saws such as bench-top models to huge floor band saw models. The compact size of the band saw helps it to be accommodative in all shop spaces as well as making them portable. Though they cannot be used for tough work, they are economic and can be used for all types of work.
Working with the Band Saw Guide
The band saws have sharp edged blades that help in resawing. By setting the right tension and through proper tacking, the resawing work is made perfectly. However, it requires practice. While resawing, you can have a nosed end block at the height of the cut, by using a short fence. The sawdust must be adequately cleared up as the cut is made, as there are chances of the instrument moving away from the line. Blade guides help in accuracy of the blade by improving the quality of work of the saw which can be avoided, if the quality of the saws bought is good. The band saw blades require good blade tension that will match the width of the blade. Resawing requires sawing of thick stock into thin stock. Good wood is selected to make various articles such a door panels, furniture, veneer, etc. The saw guide is used to keep the blade in the right position. Wide blades are used for such work. The fence helps in resawing. This can also be made of wood stock and attached to the saw table
Band Saw Guides and its Applicability
The band saw guides help in adding stability to the blade and make it work with a sharper cut and a smoother finish especially in tight curves. Rollers are placed below and above the table to guide the blades. Band saw guides are most essential for making accurate and intricate cutting work. But for ordinary work, such as the regular cutting work or for resawing, guides are not required. The guides have to be adjusted properly for improving the quality of the cut. The tension guide helps to match the tension according to the blade width. Depending on the stock thickness, the blade guides are accordingly adjusted up and down. The guide helps to provide accurate cuts through clean surfaces. They support the blade, both at the rear and at the sides through its ball bearing feature. Unless the blades make the right cut, the end product gets no value. Hence choosing the right blade also means that the blade should be well supported and used. Adjusting the band saw is most important. The band saw blade should be properly adjusted. The blade adjustment requires having proper tension by adjusting the guides. First the blade has to be installed. The tension is let down to install the blade. Once the blade is set in position, the tension is set to the width of the blade. The user should remember that, if the width of the blade is high, it requires high tension. Only if the tension is set right, the blade tracking is also good. Ball bearings are used also used as guides and these ball bearings help in reducing friction.
Making the Best Use of the Band Saw
The band saw has a sharp blade that makes good cutting work using sharp teeth. They help in making cutting work on all types of woodwork, metal work and for lumber work. They are useful in making other types of cutting works too. They provide uniform cutting as their teeth are evenly distributed and the work load is also evenly distributed. They are especially used to make all types of curved shapes as well as to make different shapes that are irregular, which is found commonly in jigsaws. By using the right blades that are well supported by the guides, working on the band saw becomes enjoyable work that is tension free.
