Wheel alignment is one of the most critical factors for optimal performance from your bandsaw.

Heat, vibration, wandering, blade wear, tire wear and overall bandsaw wear are considerably decreased when the wheels are properly aligned or “coplanar.”

Coplanar wheels automatically track the blade by balanc- ing it on the crown of the wheel. This is known as copla- nar tracking.

Checking Coplanarity

1.Make the "Coplanarity Gauge" shown in Figure 73.

Note: For best results, straighten the 2x4 with a jointer before cutting.

2.DISCONNECT BANDSAW FROM POWER!

3.Remove the fence and open both wheel covers.

4.Adjust the blade guides away from the blade, loosen blade tension, remove the table insert and pin, then remove the blade.

5.Remove the four trunnion cap screws and the table.

6.Reinstall the blade (Page 43), making sure the guide bearings and support bearings are away from the blade, then tighten your blade to the tension that it will be used during operation.

7.Place your coplanarity gauge up against both wheels in the positions shown in Figure 74.
