Things You'll Need
Instructions
Assemble your materials. Ensure that the copper elbow fits snugly with the tubing.
Cut the copper tubing into a 3- or 4-inch piece.
Solder the piece of tubing to the copper elbow. Coat both sides with flux while your solder gun is heating. The more flux, the better. Put the two pieces together ensuring that you connect the 3/4-inch side of the copper to the 3/4-inch tubing. Hold the soldering wire to the joint and use the soldering gun to melt it. Solder all the way around.
Solder your wire mesh to the top of the elbow. Use plenty of flux and an ample amount of solder.
