Re: How to make custom gas tanks...
I build tanks for all my bikes and use 18 gauge sheet metal. I have is the past silver soldered, brazed and now tig weld the tanks. The tig process seems to be the best but is not for the every day builder.
One of my best tanks is the raw look of a brazed tank that was clear coated. The "Thrasher"
Check out some of my post on my builds and you will see.
I am always open to help anyone out with advice or questions.
