It's gotten worse. My trusty old Craftsman 113 series TS is very sick. Just running a piece of pine thru it will cause the blade to actually stop. Can back it off a little and cut a little further. When I start it up it "growels a little and then smooths out. Start cutting and the noise comes back and the blade can be stopped with a little bit of pressure. I took the belt off - the motor runs smooth and quiet. Put a new belt on and that didn't help. The noise sounds like it's coming from under the table. The blade has no play in it whatsoever and it all looks good. I got to have a TS so until I either get this one fixed or replaced I may be forced (shudder at the thought) to get a contractors saw from a big box store. Any ideas or suggestions? This has been a great old saw.
