Convert a belt sander to multiple sanding shapes

Nice build where you use the belt sander to drive a larger belt with a shape on it for contoured sanding. My 2 cents, the author built a longer belt for this project, but bigger belts (well if you go really big they are expensive) are not that much more, and could be easier to manage.
