A catalyst for this seems to be Jim Cummings article “Home Shop Bandsaw” in Fine Woodworking #63. From the hundreds of bandsaw owners I’ve talked with since the article appeared, it seems there are lingering questions on how to adjust a bandsaw blade, the blade choice and operation. “To find the correct tension, you can start with the tension scale on your saw, but you will probably need to fine tune the adjustment. With the saw unplugged, increase the tension on the blade until pushing on the side of the blade with your finger using a moderate amount of force deflects the blade about a 1/4” from its normal position. An interesting experiment is to set the side guys too far from the blade and notice how increased feed pressure and turning make the blade wander.
how to adjust blade on bandsaw Related Question:
Why does my bandsaw blade wander?
If the wheels are worn and do not have a distinct top to the crown then the blade will not know where to go, and may wander around. This of course can cause poor cut quality and difficulty in setting the guides.
Why does my bandsaw blade wobble?
The blade on a saw left idle for long periods of time can leave an impression in the rubber tire which might cause erratic tracking. Purchase and install aftermarket replacement tires. (Search for “bandsaw tire” at woodcraft.com.) If you still see a back-and-forth motion, the culprit is probably the wheel itself.
Why does my bandsaw blade burn the wood?
A dull blade will make it hard to cut quickly, and the slower the feed rate of the saw, the more friction against the wood and the greater the likelihood of scorch marks. Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty.
Why does my bandsaw cut to the right?
When the band saw cuts crooked, a dull blade, improper feeding, loose blade tension or not using a work piece guide could be the cause. Use the rip fence or miter gauge to guide the work piece uniformly through the cutting blade to make straight cuts.

Why won’t my bandsaw cut metal?
Band saws are not suitable for cutting very thin sheet metal; a rule of thumb suggests the metal to be cut should be thicker than the depth of 3 band saw blade teeth, however they are excellent for cutting thin walled profiles such as box and angle.
Is it worth it to sharpen bandsaw blades?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How many times can a bandsaw blade be sharpened?
It often makes sense to replace a dull blade with a new one, but you can sometimes get the best value out of merely sharpening an old blade instead of replacing it altogether. You should typically be able to get two to three sharpenings before you need to change your blade completely.
Why does my bandsaw bounce?
A lack of straightness in either the blade or weld could be causing the blade to bounce. Next, it is important to check the blade tension and make sure that it is high enough to keep blade bounce to a minimum. That way, your blade won?t take as much damage.
Why is my chop saw smoking?
If you’re wondering why does my saw blade smoke? The simplest and most common cause for this to happen is that your blade could be getting blunt with usage. This means that the blade cannot easily cut into the wood anymore and it has to struggle and apply a lot more pressure than before.
