Great video! I'm doing something similar myself, and the tip on how to avoid destroying sanding sheets was priceless. I wish I'd watched this video before my third sheet exploded.

Thanks! I've heard 3 people say "they just come off when they are done". Did you try it with a drill driver? If so, did they hold OK?
