I am with Chuck, make a new one (and I'm a welder). If you are going to repair I would TIG weld it. I is easy relatively inexpensive and probably readily available. Silver Braze or Brass Braze are possible and are likely to work if done right but are no way as strong as a weld. I personally think brazing is more difficult to do properly. I'd bet I could make a new part in about as much time as a repair. It all comes down to what is most available to you.
