I produced a video about this a few years back and honestly, it wasn't as good as I would have hoped. Here's a link.https://www.youtube.com/watch?v=L61LJcz7H6gSince then I've improved my skills and my tools and I believe I have a much better video for you as a result. As they say however, practice makes perfect. So if you want to get good at soldering, get yourself some 60/40 solder, a good soldering iron, and some scrap wire you can practice with. Before you know it, you'll be an expert.Camera: Brian KastSpecial thanks to Ryan Blace who provided some tools and connectors that weren't seen in this video.
