LHunter, I have done this using piece of lawn mower blade filed to a dovetail and fit into a mating dovetail on a brass head, I bought from R. E. Davis. The dove tail was a very good fit, I used silver solder that I bought at a local weld shop.It is a little more silvery color than the brass, but you would need a 10x loop to see it, if at all. I don't have a picture to show you, maybe the fellow that has it will post one. I have done some brazing, but never with brass, it is so close in melting temperatures that it would be very difficult. Hope this helps, good luck.
