table saw vibration

Today, I changed out my table saw blade with a Irwin Marothon 24T. I immediately notice an increase in vibration when I turned it on. I haven't changed this blade on this saw before, so have no reference. The blade seems to run true and straight, and cuts well. But I noticed as soon as I turned it in, it had a vibration in it. Is there a break in period for a new blade, or could it be unbalanced? Should I take it back to the store?

that's at the bottom of the blade chain

Take it back and get a Diablo 24 tooth, a better blade. I have one and it works just fine, cuts well and no vibration that I can tell.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Irwin is really a low quality blade. I'm with Wooden. Just get a better blade.

Also, if you haven't ran the saw for a good deal of time the belts could have some set in them from setting in one position for so long. This will cause a great deal of vibration.

Also agree with previous posts, that it is more than likely the poor quality of the Irwin blade is causing the vibration. If you still have the "old" blade, try running that blade. If you still get vibration, it could be the belt or the flat washer on the arbor is not seated, or a combination of it all. Be safe.

Ok....per everyone's advice, I went back to Lowes, and returned the Irwin blade. They didn't want to refund it because the package had been opened. But I explained to them, I knew it was a bad blade as soon as I turned it on, and never really used it. Begrudgingly they took it back, and I bought a dewault combo pack- a 40T and 60T in one package. I put it in and cut a 3/4 inch piece of plywood, and no vibration at all. Lesson learned....stay away from Erwin blades.
