    I found this video and thought the idea was awesome that a person dose not need a welding machine to weld Aluminum and thought I would share it. I see allot of people when they are building there ships are using wood and 3D printed items as brackets for there internal parts, my self I do not own a 3d printer or want to use wood to make brackets for item hold downs.

    Harbor Freight has a similar product.
    Works GREAT!
    Just keep the parts clean and it works.

    Like brazing but needs really clean metal to work. A bit of sand paper and steel wool and you are ready to heat it up to about 700 degrees, then wipe the rod on the joint to flow the material.

    I had only seen mig, stick, or tig. It was quite a light bulb moment that welding aluminum doesn't require a welding machine, where I'm used to brazing and silflossing copper. I can stick weld but don't have a welding machine.

    I really like that stuff, and it works great. The only challenge I've found is that you have to make all of your "welds" at once. If you heat up a piece that was previously welded, it will melt when working nearby.

    thegeek's work is really nice... much better than anything I ever did, but you would have to make all those bonds at the same time (or maintain position of things that were previously "welded"
