Artist Aaron Kramer knows how to make things. He also knows how to use a huge assortment of materials. When asked about making cold connections with wire, he decided to produce this very instructive long-form video (about 10 minutes) on the topic.
From the artist:
I really haven't seen anything worthwhile on the internet so here is my take on the subject. I put together this little 9.5 minute introduction with a running commentary to impart a little of what I know. I feel a trained jeweler or metalsmith may have a different take on this so this is what you get from a self taught artist type.
Well done! I know I learned a lot.
