We used to have a sponsor weld our frame, and he always had trouble with the butt-welds. After we added gussets... even the kids could do it.

We got a really great professional welder to help us out. He agreed to do it for free as a sponsor! He's great, and he also works at a facility with pretty much every possible machine imaginable. (http://www.zmanufacturinginc.com/)
