In this video, we'll guide you through the steps to properly adjust the fence on a bandsaw, stressing the importance of taking safety precautions and checking key alignment factors before making any adjustments.
We've also included the step-by-step instructions below so you can follow along.
Important Safety Precautions:
- Disconnect Power: Always disconnect your machine from power before making any adjustments.
Initial Fence Alignment (Parallel to Miter Slot):
- Ensure Miter Slot is Parallel to Blade: Before adjusting the fence, make absolutely sure that your table's miter slot has already been adjusted to be parallel with your bandsaw blade. Refer to our other Grizzly How-To video.
- Install Fence: Install the fence on the right side of the blade.
- Initial Positioning: Adjust the fence so that it is even with the edge of the miter slot.
- Lock Fence: Lock the fence in this position.
- Check for Parallelism: If the fence face is now parallel with the miter slot, no further adjustment is necessary for basic parallel alignment.
Adjusting the Fence (If Not Parallel):
- Locate Adjustment Screws: Identify the cap screws on top of your bandsaw fence that allow for adjustment. Check your manual on how to specifically adjust your fence.
- Loosen Screws: Loosen these cap screws. They do not need to be removed completely, just enough to allow the fence to be moved slightly.
- Adjust Fence: Gently tap the fence until it is parallel with the edge of the miter slot. You can use your hand or a soft mallet for tapping.
- Tighten Screws: Once the fence is parallel, tighten the cap screws to secure the adjustment.
Confirming with a Test Cut:
- Draw a Line: On a piece of wood, draw a straight pencil line that is parallel to the edge of the board.
- Make the Cut: Feed the wood through the bandsaw, following the pencil line.
- Evaluate the Cut: If your test cut follows the pencil line straight, your fence is likely adjusted correctly for basic parallel cuts.
Troubleshooting Non-Straight Cuts (Blade Lead):
If your test cut is not straight and the blade is leading to one side, consider the following before further fence adjustment:
- Blade Tension: Ensure your bandsaw blade is properly tensioned according to the manufacturer's recommendations.
- Blade Tracking: Verify that the blade is tracking correctly on the center of the upper and lower wheels.
- Blade Guides: Check that your blade guides are roughly a quarter inch above your workpiece.
- Table Squareness: Confirm that your bandsaw table is square with the blade.
- Fence Squareness: Ensure that the fence is square with the table.
- Feeding Pressure: Check if you are applying too much pressure as you feed the workpiece through the saw.
Fence Adjustment for Blade Lead:
If the above checks do not resolve the blade lead, you can personalize the fence to your specific blade:
- Cut Freehand: Take a board with a straight pencil line parallel to the edge and cut freehand along the line for a short distance.
- Stop Mid-Cut: Stop the cut in the middle of the board.
- Mark or Clamp: Either mark the angle of the board on the table or clamp the board securely in its current position.
- Loosen Fence Bolts: Loosen the bolts that secure your bandsaw fence.
- Adjust Fence Angle: Adjust the angle of the fence so that its edge now corresponds to the angle of the test cut you just made.
- Tighten Fence Bolts: Tighten the fence bolts to secure this new angle.
Your fence is now adjusted to compensate for the specific blade's tracking and potential lead. Remember that when changing to a different blade, it is a good idea to recheck your fence angle and readjust it if necessary.
