Yes, you can use it as a "spring" to hold switch points. You use a small piece to go up into the bar from the bottom and attach it to your rod or cable or switch machine. Look at old model mags from the 60's and 70's for such uses. You can also put a stick on the ends and "saw" out windshields. A piece of piano wire and two handles use to be a mafia execution tool before they started using 22s. We use to use a 1/8 piece to launch rockets back when premade launchers from Estes seemed expensive. FRED
