Hello folks,

Can you help me with this problem I have faced…? My band-saw won’t cut straight! It moves left when I start to follow a cutting line ! The blade itself spins. I tried to changed blade tension, but this won’t help. Where can the problem be?

I would appreciate any help! Thanks in advance!

If your bandsaw has steel or phenolic “cool Blocks” as guides – you may need to take them out and square the face that touches the blade. Sometimes they get worn funny also sometimes you may have one side touching (pushing) and the other side not.

ir this just started the problem – - try a different blade.

Are the guides set correctly?

Sounds like a dull blade.

When you keep fighting against the direction the blade wants to go (called the DRIFT) you wear out one side of the blade even more.

Basically one side of the blade is duller on one side versus the other cutting, toward the sharp direction.

Try a new blade.

Could also have to do with where the blade is tracking on the wheels. From what I understand, the teeth should be fairly centered on the wheel. If it just started the last time you changed the blade, it could be the setup or you could have a bad blade.

Thank you guys for all the suggestions. I changed the blade and the problem is gone :) GaryK seems to be right. I also had this in my mind, but I couldn’t believe it, because the blade was just changed. And I actualy still can’t believe it became dull SO quickly!... On the other hand, it is still sharp! It only moves left, which kind of means that one side is duller?! I wonder if this is possible?... :) I am using “Woodslicer” blade, which I bought in the US and had to wait for a month or more for it to be shipped to Lithuania, and I am happy to get it because it really cuts great! However, everything I could do using it, was the only one Maloof rocking chair until it became dull!!! Is that normal wear??

I tried the woodslicer and had a similar problem with the blade going dull quickly. Ripping one piece of cedar killed it. I have had consistently good luck with Timberwolf blades. Some people swear by the woodslicer.

Just one more data point.
