Cool Features that should be on every vibe, marimba and xylophone

The springs on the strings have always been a pain. They scratch the bars in transit and take forever to change when your string wears out. This way, you don't need springs and you can get the string as tight or lose as you like in less than five seconds. You can also maintain a long length of string on one end and when the string starts showing signs of wear, just pull it thought and cut it off. Check it out. It should be on every instrument. I don't think I've ever shared these pictures on the site before but if I have, please forgive the re-post.
