I put together a "sound" file to help those of you that are not that familiar with the sound a scroll saw blade will make with the appropriate tension. The sounds aren't as good as the real thing, however I believe it will give you a better idea of what it should sound like. Besides this is much easier than me trying to make the sound over the phone. Just keep clicking on the image above to hear the different tensions. I made it as small as possible to eliminate download time but it still takes a minute or so depending on your internet hook up. Jerry
