Symptoms
- Cut edge isn't perpendicular to the track
- Angle is consistently off by the same small amount
- Rail shifts slightly during the cut
- Cross cuts don't match a squared reference
Likely causes
- CommonTrack saw base plate not calibrated square to the railMost track saws have an adjustable stop that can drift out of calibration.
- CommonTrack (rail) not clamped securely and shifting during the cutAn unsecured rail can move slightly under the saw's pressure.
- PossibleAnti-tip or guide rail accessory not seated correctlySome track systems have a squaring accessory that needs to be set up correctly.
- PossibleTrack sections not joined perfectly straight (on longer cuts)Connector joints between rail sections can introduce a slight kink.
What to do
- Check the saw's 90-degree bevel stop against a reliable square, and adjust the calibration screw if it's off.
- Clamp the track securely to the workpiece so it can't shift during the cut.
- If using multiple track sections joined together, check the joint for a smooth, straight transition.
- Use a squaring accessory or a large carpenter's square against the track if your system supports one.
- Make a test cut on scrap and check the resulting edge with a square before cutting the final piece.
- Store and transport the track carefully, since a bent rail will never cut square.
Tools and parts
- Track saw
- Track/guide rail
- Large square
- Clamps
When to call a pro
If the saw won't calibrate to square even against a good reference, a repair shop can check the base plate and bevel mechanism.
