How to rebnd a spring?
Hi;
Any know how to make a bend in a small spring from my door lock? I have a lock with a broken bend at one end. The steel is quiet thick like the lead from a propelling pencil and has about 1/2 dozen turns. If I can soften this spring and remake the bent by undoing one turn I think I could remake the spring. Given I can remake it springy! I have never known if this is possible as usually my attempts at rebending springs usually ends with it breaking off again. Any ideas? Regards Ian |

On the occasions I have had a broken spring I've softened the end to be wrapped around the appropriate post, I've never felt the need to re-temper that part of the spring. The rest of the spring has had sufficient "spring" in it to do the business. I'm not sure how an 1/2 inch of spring is going to effect the rest of it. It all depends on how the end of the spring is held captive in the OP's case. |

You need to anneal the spring before bending it. After that, you need to bring it back to the right temper and, if you want it to last, you also need to stress relieve it. However, if you unwind a turn, the spring will be less powerful and may not do its job properly after you have gone to all that trouble. I would take the spring down to a lockmaker and ask for a replacement. Colin Bignell |
