Where to buy a single piece of straight wire?

I need something like a guitar string, about 18 inches. Preferably from a local store. So-called 'piano wire' is hard, but if you get some, and uncoil a length, then stretch it (this requires a vise grip on each end), it gets straight. Or, hammer one end smaller, then draw through a die (it will take some lube). |

It's very straight. -- Ed Huntress |

Or, hammer one end smaller, then draw through a die (it will take some lube). You would be hard pressed to stretch a piece of music wire over .010 by hand. It's pretty tough to draw too. Some time back, an RCMer from the golden years wrote this about this very subject. We routinely straighten music wire of all diameters at work. We use it for hinge pins on aircraft. Our music wire comes in large rolls. The way we do it, is to take a piece of tubing and bend it in sort of a relaxed z shape as below. ---------\ \ \------------- Clamp this in a vise. Cut the wire to length, and insert one end into an air or electric drill. Insert the other end into the opening of the bent tube, and turn on drill, and force wire through the bent tube. Once its through a bit on the other end, then place the ch=uck on this end, and then just run drill and pull the wire through the bent tube.. Push it back and forth a few times, and when it comes out it will be straight. A little oil may make it easier. We have straightened music wire up to .185 this way. foxeye It works pretty well.
