It's a rare day a guy could start building, go to the shows, and sell everyone from the getgo. Ten years ago it happened for some guys, but that was a perfect storm and they had a good leg up. I agree with Andy, giving them away is just like selling them and not a responsible action for your future. I know there are guys out there doing that, but it's not the right way to do it. You need to make frames intensively as you refine your style and gain skills. It costs money, and is just like going to school. So my recommendation is to go to UBI and build a frame, then go home and spend the time and money to repeat that frame about a dozen times within the first year. Move your parts from one to the next and retire them to the attic or cut them up. Paint them with spray paint as you go, you wouldn't believe how much you learn about your metal work when you start putting paint on. After that first year and a dozen frames evaluate where you are. It'll be money well spent any way you look at it. And don't build bikes for the road without provisions for brakes at both ends.
