Build a Spring-Loaded Table Saw Featherboard
A featherboard is a handy accessory for keeping workpieces firmly against the rip fence while making cuts at the table saw. But getting the pressure just right can take some trial and error.
Position a conventional featherboard too close to the workpiece, and it becomes difficult to feed the stock. Set it too far away, and it won't provide enough pressure to keep the board against the fence.
This shop-made spring-loaded featherboard offers a different approach.
Instead of relying on flexible fingers, it uses a spring hinge like those found on storm doors. The hinge applies pressure to a pivoting wooden arm, helping maintain contact with the workpiece as you feed it through the saw.
It's a clever table saw accessory that can make ripping operations more convenient.
How the Spring-Loaded Featherboard Works
The design is simple. A wooden arm is connected to a mounting block with a spring hinge.
As a workpiece passes the arm, the spring applies pressure that helps hold the stock against the rip fence.
Unlike a traditional featherboard, which requires careful positioning to establish the correct amount of finger pressure, the hinged arm can pivot to accommodate some variation in workpiece position.
Some storm door spring hinges also include a tension adjustment, allowing you to fine-tune the pressure.
The featherboard mounts to the table saw using a hardwood runner that fits into the miter slot.
This keeps the accessory positioned alongside the workpiece during ripping.
Building the Table Saw Featherboard
You can make this accessory from a few pieces of wood, a spring hinge, and a small piece of self-adhesive sandpaper.
Step 1: Make the Base and Miter-Slot Runner
Start by making a thick wooden mounting block.
Fasten the block to a runner sized to fit the miter slot of your table saw.
The runner should fit smoothly without excessive side-to-side movement.
Because the spring-loaded arm applies sideways force, the base needs to be held securely in position. Provide a positive locking arrangement that prevents the runner from sliding or lifting during use.
Step 2: Shape the Featherboard Arm
The pivoting arm is the main working part of the featherboard.
Cut a miter on one end of the arm to accommodate the hinge and mounting arrangement.
Round over the opposite end, where the arm contacts the workpiece.
The rounded end allows the arm to maintain contact with the stock as its angle changes.
You may need to adjust the length of the arm to suit your table saw and the distance between the miter slot and rip fence.
Step 3: Add a Gripping Surface
To improve contact with the workpiece, apply a piece of self-adhesive sandpaper to the rounded end of the arm.
The sandpaper provides a little extra grip as the stock moves past.
Keep the abrasive securely attached, and replace it if it becomes loose or worn.
Step 4: Install the Spring Hinge
The final step is connecting the featherboard arm to the mounting block.
Use a spring hinge designed for a storm door or similar application.
Position the hinge so it urges the arm toward the rip fence.
If your hinge includes an adjustable spring mechanism, follow the manufacturer's instructions to set the tension.
Setting Up the Featherboard for Rip Cuts
With the featherboard assembled, slide the runner into the table saw's miter slot and lock it securely in place.
Position the accessory so the arm contacts the workpiece entirely ahead of the saw blade.
This is especially important when applying sideways pressure during ripping.
A featherboard positioned alongside or behind the blade can push the freshly cut material against the rear teeth, increasing the risk of kickback.
Adjust the Spring Pressure
With the saw turned off, place a workpiece between the featherboard and rip fence.
The spring-loaded arm should apply enough pressure to maintain contact with the fence without making the board difficult to feed.
If the hinge has adjustable tension, start with a light setting and increase it only as needed.
Move the workpiece through the setup by hand, with the saw off, to check that it slides smoothly and doesn't bind.
Check the Feed Direction
Traditional featherboards have angled fingers that resist backward movement. This spring-loaded design works differently.
Its main purpose is to apply sideways pressure and help maintain fence contact. It should not be relied upon as an anti-kickback device.
Use the table saw's riving knife, blade guard, and other appropriate safety equipment.
A push stick or push block may also be necessary to maintain control while keeping your hands away from the blade.
A Handy Upgrade for Your Table Saw
This shop-made featherboard is a practical alternative to a conventional finger-style design.
The spring hinge allows the arm to pivot while maintaining pressure against the workpiece, reducing the need for precise manual adjustment.
And because it's made from a few basic materials, it's a straightforward addition to your collection of table saw accessories.
For woodworkers who frequently make rip cuts, it's another useful way to improve workpiece control and consistency at the table saw.
