I had to sand some chair legs. I got out the rubber nonslip pad and went to work. I wasn't making much progress. The hand holding the chair leg was getting numb from the vibrations.

I moved over to the bench with the vise and used the vise to hold the work. Even having to shut the sander down, rotate the work and start back up the results were so much quicker. I did the remaining 10 legs in about the time that it took me to do just two legs.
