Automatic band saws are very beneficial for any do-it-yourselfer and are one of the easiest and most reliable methods of cutting through large logs. It has a band saw blade that moves on the rails that turns a gear drive. This mechanism moves the sawing blade along a belt which is connected to the motor. This is the most common kind of saw used in building home projects as they are very powerful and reliable.
The power supplied to the motor through a series of electric wires is divided into anode and cathode. This wire then powers the motor when the blade is not in use. On the other hand, when the blades are spinning, the wire supplies an anode. The anode then supplies a negative charge to the blade and cause it to spin on a belt.
Number of Blades – If you have a small do-it-yourselfer at home, you can easily go for a smaller and less powerful saw. There are also some smaller automatic band saw available which is of lesser capacity. If you have a big scale project which requires a large amount of cuts, you will require a bigger model.
Blade Diameter – The bigger the blade, the larger the size of the sawing area which will be required. However, you should also keep in mind that a wide blade of small diameter will be a lot more cumbersome to use than a smaller sized blade.
Gears – There are several types of gears that can be used in the automatic band saw. The basic design is the straight shaft that turns the wheels, the same design is used in regular saws.
Blade Thickness – When you buy a manual band saw, you will get three kinds of blades, a straight blade, a long thin blade and a very thin blade. If you want to create a project where a lot of material will be cut on a single pass, you should opt for a very thin blade. The thin blade is sharper and is better able to cut through wood, metal and even concrete.
Blade Speed – There are two basic blade speeds for a band saw, the first one is the self-starting speed, this is what most of us are familiar with. The second one is the manual, when the blades are turned manually.
Installation – An automatic band saw is not as easy to install as manual band saws. However, they do tend to be quite easy to use and install, however, they may take a bit longer than manual band saws to start up.
