My Rigid spindle sander has been giving me some problems, and I wonder if anyone else has had to deal with what I am about to describe. Sometimes, the sanding sleeves have a tendency to ride up, on the spindle, during operation. Also, I can just BARELY touch wood stock to the spinning spindle/sleeve. Anything more than just very slight pressure, and the sleeve will freeze from spinning, on the rotating spindle. And when I say very slight pressure, I mean just that. I have to try and find my owner's manual, to see if it (hopefully) contains a corrective counter action for the above.
