You can use the low temp silver solder (2% silver, the stuff that comes coiled up at the local hardware store) wich allready has acid flux in the core.

Simply clean the end of the rod with some sandpaper, put the clevis on and heat with either a high wattage iron, soldering gun or a small butane torch. You dont want it TOO hot, just enough to let the solder flow out easily. Glowing red is NOT good. I find the acid core stuff will clean itself pretty well, and you dont have to get super critial in preparing the parts.

Real silver brazing wire (high temp stuff, 45 to 50% silver) is NOT good for this job, you need to get the parts too hot and the clevis will loose the springiness (temper) and may break easily afterwards.

I actually find it easier to do with an iron (assuming the iron is not a small electronics one, but large enough to heat the parts) simply due to you not being aboe to overheat them, as you can with a torch.

Another good idea is to tin the rod (apply a bit os solder to it before assembly) first, then place the clevis on and resolder.

One last thing, for a really good, strong bond, do not let the psrts move untill the solder cools and solidifies. If you keep moving them around you will get a cold joint (looks dull and grainy) which is not nearly as strong.
