I just bought a leg vice, and it needs a new spring. I want to buy one from Poor Boy Blacksmith Tools on Ebay but there are three different sizes and I don't know how to tell which one I need. Can someone tell me how to find out? Also this vice has a washer that looks like it was welded but the welds broke, and another washer-like piece between the handle and clamp part that has broken welds. Do these even need to be re-welded or is it o.k. for them to be free moving. I'm sorry about the hard to understand descriptions, but I don't know what all the parts are called. I might try getting pictures up soon. Keep in mind I don't currently have a forge so I can't make my own spring or other parts. Any help is greatly appreciated. By-the-way, this is my first post.
