How to Change the Blade and Tires on a Vertical Table Saw

by Douglas Watson

​When you begin to notice that your vertical table saw is not cutting properly, it may be time to change the band saw blade or the tires. Both are simple to replace and usually require no tools.

How does a band saw operate?

A band saw, whether it is hand held or mounted on a table either vertically or horizontally, use two pulley wheels to rotate a band saw blade, which is shaped as a continuous loop or "band." The teeth of the blade are then able to cut in a circular motion.

Because the pulleys as well as the band saw blades are made of metal, there is little or no friction between them. This lack of friction allows the blade to slip around the pulley wheels, resulting in a slowing of the blade's rotation. This decrease in blade speed inhibits its ability to cut.

Enter the band saw tire

A band saw tire is a thin band of rubber that fits within the groove of the band saw's pulley wheels. This thin layer of rubber between pulley and saw blade supplies the friction needed to hold the blade in place.

Because band saw tires are made of thin rubber, they must occasionally be replaced.

How do you know when a band saw blade or tire needs replacing?

A band saw blade must be replaced when

  • Cut edges become rough and jagged
  • The saw  takes a longer than usual time to cut
  • The blade breaks or gets trapped in the item to be cut

A band saw must be replaced when the pulley wheels are turning at normal speed but the blade is turning very slowly or not at all.

How do you replace a band saw blade in a vertical table saw?

To replace the blade, you should first unplug the saw to avoid accidents. Next, you will need to access the pulley wheel areas. These are located at the top and bottom of the table saw,

Open the access doors with either a screwdriver if a screw is present or by turning the handle on a cam lock attachment. When the access doors are opened, loosen the top pulley wheel by turning the adjustment dial at the top of the saw.

When the top pulley wheel is loosened sufficiently, remove the blade from around the pulley wheels. Use this opprtunity to clean accumulated wood or metal dust from inside the saw.

If a band saw tire needs to be replaced, it will usually be broken or shredded, so remove it from around the pulley wheel and install a new one by stretching it over the wheel until it is seated in the groove. Be careful not to pinch your fingers between tire and wheel. It is very painful.

Your new band saw blade will probably be folded and bound by a cardboard clip or tie wire. Be very careful when removing the clip or wire because the blade will suddenly spring into its normal round shape, which will expose everyone nearby to flying saw blade teeth.

When installing the blade, you must be certain that the teeth are pointed downward. Seat the blade into the pulley wheels and tighten the top pulley wheel with the adjustment dial until the blade is tight and rigid.

Replace the access doors and plug in the saw, check the band saw blades, and you're ready to cut.
