Recently I asked an old friend of mine who used to weld for a living about helping me with my project. He was able to stop by last night to talk about the bike. As it turns, he is not only willing to show me how to weld, but excited to do so, since he's no longer doing it as a profession and misses it (damn economy). It also turns out he's got an old Yamaha 400 sitting in his yard that he's been considering trying to put back on the road.
In return for his help, I've offered up my garage, my tools and my limited knowledge to help him get his Yamaha back on the road. It was a daily rider a couple years ago, and it's complete, so it shouldn't be too bad.
After talking with him, I feel confident I'll be ready to send my frame out for powder in about a month or so.
