Craftsman table saw vibration

I have a 10" Craftsman contractor saw. I would prefer a cabinet unit but it just isn't in my budget. The model I have has the router table extension and in most aspects works well though I am considering a Bedemeyer (sp?) type fence.

My problem is that it make what I consider to be too much noise and vibration. I have carefully adjusted the pullys and replaced the continuous belt with a linked one to minimal effect. I am thinking that the arbor bearings may be worn but I thought I would ask for another opinion before I tear it down. If it helps in the diagnosis I notice a subtle clicking sound as the blade comed to a halt.

My first guess would be that the blade is not seated correctly. Maybe the washers on the blade are worn, or the bolt is worn or that the blade is not tight enough. All of the symptons you described are signs of a blade problem. Good Luck

The only things that can cause vibration are rotating assemblies, blade, belts, motor, etc. Worn bearings anywhere should be quite noticeable. Grab a shaft and try to move it, should be no play. And out of balance blade is different, swap blades???? Or remove the blade. But do not run it for more that a few seconds without a blade.

If you have a dial indicator you can check both the blade and the shaft. A cheap set up from Harbor Freight only costs about $15 dollars on sale.

As stated before, a blade issue may be the problem. It may be out of balance. I have had this problem before, and replacing the blade was the answer. At least it's the less expensive - and less time consuming fix, if that is in fact the problem.

The clicking noise may indicate bad bearings, but try the blade first. If it's not the problem the worst that can happen is you've got an extra blade.
