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.
Of course your budget will eventually dictate the decision to buy. The size of bandsaws Bandsaws are generally grouped by size. Woodworkers often mistakenly assume that the stated size refers to the throat capacity (blade to frame) of a given machine. This is not correct as the throat capacity is normally very close to the wheel diameter which does not determine their size. Blade capacity of bandsaws varies and is an important consideration as it dictates to a certain extent what a woodworker can cut. The narrowest blades on a bandsaw will allow for very fine and intricate cutting while others slightly wider will cut graceful shapes easily. The wider the blade the easier it is to cut straight as the blades have the tendency to twist while performing the cutting action. Bandsaws that suit your business The smallest bandsaws are designed for benchtops and are usually in the range of 8". These are lightweight compact and designed for light work.

The fine dust that this type of saw discharges adds to this issue. A bandsaw that has a cleaning brush will stay cleaner with less effort on your part. Placing a bandsaw brush onto your saws lower wheel tire is an easy way to prolong the tires life. Without the brush the saw dust metal shavings or debris will build up on the saws tire. Eventually this can result in wear as a result of compression and can significantly shorten the life of the tire. Another worthwhile feature is a built-in dust collection port allowing it to be connected to your shop vacuum. Additional Functionality Finally having a miter gauge as well as a rip fence will greatly increase a bandsaw s functionality. These two features are especially effective for ripping cross cutting and resawing.
Again using the tension wheel (knob) apply tension to the new blade. You may need to hold the blade in place until the tension itself becomes enough to maintain the blades position. Just exactly how much tension you apply to the blade is dependent upon the type more specifically the width of blade youve installed. There should be a tension-indicator on the back of your bandsaw to help you find the proper tension for your blade. Tracking: Once youve applied proper tension to the blade it needs to be tracked or centered. Using the tracking knob on the side of the band saw you can perfectly center the blade on the blade-wheels. Turn this knob while using your other hand to spin the blade wheel. This will allow you to see all of the blade and to track it accordingly. Adjusting: Next finalize the adjustments to your upper ball bearing guide which should sit just exactly behind though not touching the blade. There should be only a hairs breadth of space between the guide and the blade.
