ok everyone has told him how to solder but nobody told him how to SOLDER.

note this is with an iron as I dont do torch soldering (d***it jim, im an electronics geek not a plumber)

first thing to do is if you are using a iron get it hot. then clean the tip, the best way to do this is with a wet sponge. with the sponge sitting in a tray of water (to keep it wet while you work) just wipe off the tip whne its hot, the water will keep the sponge from burning and the tip should be a nice and shiney ,

now "tin" the tip, take a small bit of solder and basically "paint" a bit of solder on the tip to coat it, this gives the most heat transfer and helps keep the tip clean.

clean both surfaces using brillo, snadpaper, scratch with a knife etc, you want bare shiney metal here.

when soldering something like a clevis I like to heat the rod up first becuase this is the item that will be the hardest to heat (takes longer to heat up because it tranfers alot of heat down the rod) so I apply heat to the rod right were the clevis and rod meet.

I then touch a bit of solder right at the tip of the iron and the "work" to aid in getting the heat to flow to the metal.

after about a second (if the iron is hot enough) the rod should be hot enough to melt the solder, I apply solder on the opposite side from the iron to make sure the rod is hot enough.

I apply a touch of solder, let it wick, then apply some more, if you do it all at once you will just have a blob of solder on top of your work, do this till you see solder from both ends of the clevis (or till its full if its a enclosed type of clevis.

now *keep the heat on* for a couple of seconds to let the solder "bond" to the metal, when you remove the heat be careful not to move the clevis as this could break the joint, let it cool and it should "glaze over" as the solder solidifies. it should stay fairly bright if its strong joint if it looks grey to silver then it should be fine, if it looks "white" its probably a "cold joint", just apply heat again and it should bond correctly.

when it cools down give a good strong tug to test the joint, better to have it fail now and redo it then to have it fail in flight. oh and make sure its COLD before you touch it... its amazing how long something can stay hot, not to mention how long you can hold something before you realize its hot. I have the burn scars to prove it

this is how I have soldered for the 10+ years I have been doing electronics and it hasn't failed me yet.
just remember, heat the work, not the solder.
