moved resources/shop/bandsaw to resources/shop/band_saw so the url shortener would work.
if the url shortener works, then people who need to buy blades for the band_saw will come here, and find out what the UPC is for band_saw blades. voila! a useful url shortener in the real world.
 nburl.net urls can be changed.
The nburl.net urls can easily be changed. Just delete the current url and create a new one with the same shortened name.
