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 balancing it on the crown of the wheel. this is
known as coplanar tracking.
To check if your wheels are coplanar:
1. Make the "Coplanarity gauge" shown in
figure 63.
Note: For best results, straighten the 2x4
with a jointer before cutting.
2. remove the fence and table, then open both
wheel covers.
3. Make sure the guide blocks and rear sup-
port bearings are away from the blade, then
tighten your blade to the tension that it will be
used during operation.
4. place your coplanarity gauge up against both
wheels in the positions shown in figure 64.
5. the adjustment hub allows you to move the
lower wheel in the desired direction. turning
all the bolts clockwise in equal amounts push-
es the wheel forward. turning all the bolts
counterclockwise brings the wheel backward,
closer to the adjustment hub. Used individu-
ally, each bolt can control the direction that
the wheel tilts.
