The heating bit
The metal I am using is 3/4" wide by 1/4" thick , so it is wider than most tangs if yours is thinner it will heat up much faster.
Start heating the work up it will take a little over 5 mins before you put the rod on.
Once the the work has reached a good red heat, start to apply the rod. the flux will start to bubble and melt off the rod onto the joint, run the rod along the joint to deposit flux so the brass can run into it. As the rod heats up the rod will melt if the metal is hot enough it will run like solder if it just forms a small brass ball the metal is just not hot enough yet just keep the heat on and it will soon flow Footnote the hottest part of the flame is right at tip of the blue flame dont put the torch to close to the work.
Once you have done one side turn over and braze the other joint once the brass is flowing run the rod along the side seam, on both sides.Keep the heat on after you finished with the rod and check that the braze has completely run into joint ,dont worry if you have put to much braze on it can be ground off.
This is what you are left with ,let it air cool of for a good 5 mins and take it of the fire bricks straight away the melted flux will glue the job onto the firebricks :lol: after that if you want you can cool in water.
