   Bill,

   This is hard to do at a distance.  Presuming that the problem isn't as simple as a loose bolt or a part having come loose, the most likely cause is either a loose pulley or a bearing that is starting to go.  A belt that is worn out, and possibly missing a chunk of its rubber, is also a possibility. 

   Checking the pulley and bearings will require you to take off the belts to get access to the set screws and also so you can spin the motor and arbor shafts freely.  I would check for a loose pulley soon since a shifting pulley will severely damage both its bore and quite possibly the shaft it is mounted on.  If a bearing is developing a problem you can continue to use the machine for awhile if it can't be repaired immediately.

   Thanks for the prompt response!  I was afraid you might say the bearing might need replacement.  I'll check pulleys and belt first.

   Thanks again for your suggestions.......
