The next step depends on how mechanically inclined you are or are how much you are willing to learn or tinker. Personally, I’d tear into the thing and have a look around. I’m not sure how the radial motion is achieved in those units. Being 15 years old could mean there is some grease that is starting to get very tacky and getting really cakey with the saw dust, gumming up axels or chains or whatever else may be moving in there.

Also, I misunderstood your issue earlier. Is the table belt moving when you turn the unit or or is it just able to freely move when you push against it? Are there any strange new buzzing sounds when you turn the unit on or does it sound quieter? Be extra careful not to leave the unit on for more than a few seconds if you do hear buzzing.

Otherwise, if the unit doesn’t turn on at all (how I previously understood), it seems more like a motor issue, rather than a drive train issue (belts. chains, gears) but it could be both in the end. You could have an overheated motor which could be from low available current (if you had other appliances on) or from over high current draw if something was ceasing up the drive train.

There are still other possibilities but these are the likeliest that come to my mind.

Edit: Also, did the table belt typically freely move and did the drum freely move prior to this? Did they both move if you moved one? Its a good possibility that the drive trains are completely separate. So it is possible that the mechanics of the drum have ceased up or it could be that the drum used some special gears that would inhibit motion by pushing on the drum.
