I've recently made DIY Cat5 Speaker Cable for my home cinema. I would like to solder the banana plugs, to achieve an anti-oxidised connection. I have bought a solder iron and some solder, and have been trying to solder the plug in various ways, but the solder does not want to stick. I have searched the Internet for the ideal guide to soldering, but all they seem to contain is how to solder joints such as circuit boards and such. If anyone has DIY'ed their Cat5 cables and soldered them too, I would appreciate a quick informative guide, with pictures if possible. Thank you in advance.
