Changing a bandsaw blade can be time-consuming and expensive, but it’s also necessary to keep your saw running smoothly. Bandsaw blades are sharp, effective, and dangerous. Luckily, changing a bandsaw blade isn’t too complicated after you get the hang of it. This blog post will cover how to change a bandsaw blade with step-by-step instructions on what tools to use and how to make sure everything is done correctly.
How to Change Bandsaw Blade
Below are the step describing how to change a bandsaw blade. Note, that the details may differ depending on the model of bandsaw you have.
Turn off your bandsaw and unplug it. By doing so you are removing any chance of injury.
Secure the blade into the lower part of your bandsaw with push pins or similar, this will stop it from moving when you remove it.
Using a wrench, undo the nut at the bottom end of your saw blade. Once undone, pull off the old blade and discard it. Now place on your new blade, make sure that teeth are pointing down towards the tabletop. After checking that it’s secure to half-inch out both ends until you hear a clicking noise, then give around a quarter turn back inwards just to keep it in place.
Align (or use an alignment tool) to make sure the teeth are facing straight up vertically when you put in your new blade. If they aren’t, adjust them on either side before placing a new blade onto blade holders and tightening back down using the same process as above only in reverse order.
Plug in and turn on the bandsaw. Now it’s ready to cut.
What Happens If You Don’t Change Your Bandsaw Blade on Time?
Well, the answer is pretty obvious: you will keep cutting wood with a dull blade, which can make your cuts uneven or even cause them to be off-center. Also, it can be dangerous for the material and the blade itself.
Signs That You Should Change Bandsaw Blade
When your bandsaw blade gets dull, you need to change it and keep on working with a new one. But how to know when the blade is no longer useful? There are some signs that indicate that it’s time to replace your bandsaw blade:
1 – Dull cuts
If your wood looks like sandpaper because of all the roughness left on its surface by the saw blade, then it’s time to get a new one. A sharp blade will effortlessly cut through wood leaving only smooth surfaces behind.
2 – Uneven cuts
If you see high or low points on each face of your workpiece after cutting, it means there were inconsistencies in your bandsaw blade. You need to get a new one because it can cause serious problems for your machine and if you want to avoid accidents, the best thing is to keep on working with quality equipment.
3 – Deformations
If you notice any deformations in the wood, the saw blade has probably worn out already and needs to be replaced. Another sign of wearing out is jagged cuts that are not clean but look like an arc. This happens due to overuse of tension springs or just because there’s too much play between the guides and blade teeth. If this is happening, it’s time for you to replace your bandsaw blade.
4 – Curving
Another indicator of poor performance caused by wear-out means curving cuts which can happen if the blade guides or bearings are worn out. These need to be replaced anytime you notice them.
5 – Blade tension and tracking
If your blade is not held at a certain level of tension and tends to wander off its original line, it’s time to get a new one or tighten the ones that hold it in place. If there is no tension on your bandsaw blade, the saw blade will just stop while working, then you’ll have to push harder on the wood, which can cause ripping.
Changing a bandsaw blade is not as difficult as you may think. Everybody can do it even a DIYer. There are several ways to go about it. Follow these simple steps above to change your bandsaw blades and keep them sharp for longer periods of time, which will allow you to be more effective in your shop or workshop.
