What do Jet 1220 bearings sound like when they are going bad?

In German, dogs don't say "woof". Even MAKING animal sounds in China, we never figured out WHAT we were EATING!!!

Thanks, all. Especially Randy. I looked in the library before I posted, didn't see anything. I'll go back and have a look a that article, in case I need to changed them. olivier is right, I think, all new noises are bad. Its also starting to make a new noise when it starts up, a quick, quiet thump sound, kind of. ( Sounds are hard to describe.) That one can't be good either. Well, thanks again. Wish me luck. I need to get it solved, since there are not enough pens in the world. Dave

Another way to check is to use a mechanics stethoscope and probe each bearing until you find the bad one. They are available from Harbor Freight for about $7.00. Also make sure bearings are rated for the RPM's you need.

Would a stethoscope be sensitive enough the allow one to figure out which of the two bearings was making the noise?
