Tuning Up a Bandsaw

A bandsaw is a versatile and useful wood working tool. Band saws require proper tuning to perform effectively and safely. 

Step 1 - Safety

Disconnect your band saw from its power source. Put on your protective eye wear.

Step 2 – Installing the New Blade

Open the band saw doors. Install your new blade. Raise the band saw guide to the highest level.

Step 3 – Tightening the New Blade

Tighten to the new blade. Check the tension by plucking the new blade. Listen for a tone created by the blade movement. If the blade produces a thud, it needs to be tightened.

Step 4 – Checking Blade Deflection

Push the blade sideways under the guide. Check for any blade movement. Raise the guide to the highest level. Push the blade sideways again. The blade should deflect no more than a quarter of an inch. If the blade deflects more than that, it needs more tightening. If it deflects less than that, it needs loosening.

Step 5 – Tracking the Blade

Check that the blade is running in the middle of the band saw wheels. The blade tracking can be adjusted with the knob behind the top wheel of the band saw. 

Step 6 – Squaring the Blade

The knob locking the table in position will need to be loosened. Use the square to ensure that the table and blade are in the correct position. Tighten the knob 

Step 7 – Testing the New Blade

Use some extra pieces of wood to test the new blade. Reconnect the power source. Turn on the band saw. Make some test cuts into the wood to be sure the blade is moving and cutting properly.
