Tension: Adequate blade tension reduces the blades tendency to lead erratically under thrust. I have found that the standard tension gauge is not accurate. It is better to use a little more tension than indicated. You can check it by opening up the thrust bearings and lateral guides. Back off both above and below the table so they do not contact the blade. Crank the tension gauge to the desired setting. Give the blade a sideways nudge about halfway between the upper and lower wheels. The blade will deflect easily for a short distance. This sideways movement should be 1/4". If you push harder it will bend farther but there is a distinct point where it quits deflecting easily. If you can deflect more than 1/4" then add tension until this deflection is 1/4". Stock Control: How does one cut straight lines? Answer: find out how the saw wants to do it and do it that way.
As it turns out removing and replacing the blade on a bandsaw requires a significant bit more effort and patience from the operator. Dont let this fact dissuade you though with the right bit of know-how replacing the blade on your bandsaw can be as easy as pie - and just as satisfying. Safety: The first step of course is ensuring you are safe and prepared for the impending procedure. This means you must disengage the bandsaw and unplug it from its power source. This also means that you should be wearing goggles and preferably long-pants. Bandsaw blades have a tendency to fly off the handle so to speak. Removing Your Former Blade: Removing the old bandsaw blade is the next step. First you will usually need to remove the blade insert and the table pin from the saw table.

The bench mounted units being smaller are something a woodworking hobbiest is more likely to have. The floor stand models with larger motors and more options are also generally better built much heavier and sturdier. With bandsaws the heavier and sturdier frame will definitely lead to more accurate consistent cuts. Believe me with a bandsaw vibration is NOT your friend. Cutting Capability In reference to cutting size the two issues to consider with a specific model are: The DEPTH of the cut (the distance from the table to the upper blade guides) The Saws THROAT depth (distance from the blade itself to the vertical frame section of the body of the saw) The DEPTH of the cut determines the thickness of stock that can be cut using that bandsaw.
In fact many a woodturner will use firewood and logs designated for land fill instead of buying lumber that has been cut to size and often kiln dried. However there is still a fair amount of labor that is needed to get the wood to the lathe. Chain saws start the process and a good band saw can do quick work of getting the wood ready for the lathe. A turner will bring four basic forms of wood to the lathe log sections bowl blanks squares and sections of boards. The latter is used for specialty items and the first three are far more common. While a chain saw is the ideal tool for bucking saw sections to length a bandsaw can easily be used if a v block or clamp is used to prevent the wood from rotating while a cut is being made. The bandsaw for this and any cut in green wood should be set up with a three eighths inch three tooth blade. A hook tooth style blade will cut aggressively in green wood and still be able to clear its gullets of wood chips and sawdust for safe clean cutting. Ensure that the wood cannot roll and that the blade is at proper tension. It should be a new or freshly sharpened band. Consider the preparation of a bowl blank. The chain saw is used to cut a log section the same length as the diameter of the log and then to cut the section through the center of the log. This ensures a flat surface to lie on the bandsaw table.
