I am looking for information about wire saws. Where do I buy it? Anyone built one lately? Material will be aluminum.

The wire saws that I am familar with are used for cutting glass, tile, and ceramics. Just do an internet search for "wire saw" or "wire bandsaw". Lot's of good sites pop up.

I have on my list of things to do is to build a CNC stained glass cutter. I've never seen one, but think that is might work well.
