Tools You’ll Need

With the right tools and some patience, you’ll be able to replace your old blade with ease.

To start off, you’ll need a few basic tools, a screwdriver, pliers and, of course, the new blade itself. Depending on what type of saw you’re using, there may also be other specialised tools that are needed, such as hex keys or wrenches. Be sure to check your manual for any specific instructions before beginning work on your saw.

To replace a scroll saw blade, you’ll need the right tools for the job. With those in hand, it’s time to move on to removing the old blade.

Removing the Old Blade

Removing the old blade from your scroll saw is a relatively simple process. Before you begin, make sure to unplug the machine and wear safety glasses for protection.

Start by loosening the screws that hold the blade in place. Depending on your model of scroll saw, there may be two or four screws located at either end of the arm that holds the blade in place. Use an appropriate screwdriver to loosen these screws until they are no longer tight but still remain attached to their respective arms.

Next, release any tension on the blade itself by turning a knob or lever located near where it attaches to one of its arms. This will allow you to remove it without putting too much strain on yourself or damaging any parts of your saw’s mechanism. Once this is done, carefully slide out the old blade and set it aside for disposal later on.

Finally, inspect both ends of each arm that held your previous blade in place for any signs of damage, such as rusting or corrosion, before proceeding with the installation of a new one. If necessary, replace them with new ones before continuing with installation to avoid risking further damage down the line due to faulty components being used instead.

Once the old blade has been safely removed, it’s time to move on to installing the new one.

Installing the New Blade

Installing a new blade on your scroll saw is not as difficult as it may seem. Before you begin, make sure to gather the necessary tools: a screwdriver and an adjustable wrench or pliers.

Adjusting Tension

Before installing the new blade, adjust the tension knob so that it’s tight enough for cutting but not too tight that it will damage the blade. To do this, turn the tension knob clockwise until you feel resistance. Then back off one-quarter of a turn counterclockwise and check if there is any play in the blade when pulled up or down with your fingers. If there is still some play in the blade, tighten slightly more until there is no movement at all when pulled up or down with your fingers.

Installing The New Blade

Once you have adjusted the tension knob correctly, place your new blade into position on top of two pins located near each end of the throat plate (the metal piece beneath where you insert blades). Ensure that both ends are securely inserted into their respective pins before continuing further.

Next, use either an adjustable wrench or pliers to tighten screws located on either side of where you placed your new blade onto its pins – these screws should be tightened firmly but not overly so as to avoid damaging them or warping any parts within your scroll saw’s body frame. Once they are tightened properly, double-check by pulling gently upward on each end of your newly installed blade; if it does not move, then everything has been done correctly.

Testing It Out

Finally, test out how well everything works by turning on the power switch and running through a few cuts using scrap wood pieces first before moving on to larger projects. This way, you can ensure that everything was installed correctly without risking ruining expensive materials right away.

Key Takeaway: To replace a scroll saw blade, adjust the tension knob, insert the new blade into position on top of two pins, and tighten screws with an adjustable wrench or pliers. Test it out by running through a few cuts using scrap wood first before moving on to larger projects.

FAQs in Relation to How to Replace a Scroll Saw Blade

How you would change the blade on a scroll saw?

Changing the blade on a scroll saw is relatively straightforward. First, unplug the saw and remove any existing blades. Then, loosen the tension knob or thumbscrew to release pressure from the blade holder. Carefully slide out the old blade and replace it with a new one, making sure that its teeth are pointing down towards the table of your saw. Finally, re-tighten the tension knob or thumbscrew until you feel resistance in order to secure your new blade in place. With this done, you can now plug back in your scroll saw and get cutting.

How do you put a pinless blade on a scroll saw?

To attach a pinless blade to a scroll saw, start by loosening the tension knob located at the top of the saw. Then, insert one end of the blade into the slot on the upper arm and guide it down until it reaches its full length. Securely tighten the thumbscrews on both sides of this arm to hold it in place. Finally, adjust and secure the lower arm’s tension knob so that there is enough pressure for cutting but not too much that would cause damage or breakage. Once done, you can begin using your scroll saw with a pinless blade.

How do you tension a scroll saw blade?

Tensioning a scroll saw blade is an important step to ensure accurate and safe cutting. To do this, loosen the tension knob on the back of the saw. Insert your blade into the slot, making sure it’s facing in the right direction. Tighten the thumbscrew until you feel resistance when pulling on either end of the blade. Finally, turn the tension knob clockwise until it stops; this will create enough tension for proper cutting without damaging or breaking your blades. Once complete, check that there is no slack in your blade before beginning to cut.

Are scroll saw blades universal?

No, scroll saw blades are not universal. Different types of blades have different sizes and shapes, which means they can only fit certain models of scroll saws. Additionally, the thickness and tooth count of a blade will determine what type of material is suitable for cutting. Therefore, when purchasing new blades for your scroll saw, it is important to check that they are compatible with your model before making a purchase.


With the right tools and a bit of patience, you can easily replace your scroll saw blade in no time. Just remember to take safety precautions when handling sharp blades and make sure that you’ve securely installed the new blade before testing it out. Now that you know how to replace a scroll saw blade, you’re ready for any project.
