Todd Ingermanson of Black Cat Bicycles has put up a very detailed article showcasing a full frame build. Todd includes many photos throughout the article. It shows from the first top tube to the finished product what steps are involved in hand building a mountain bike frame. He shows some really nice tools he uses to keep the frame straight and what the build looks like in raw form as he welds and brazes the tubing. If you’ve never seen a build project yourself this is a must read article.
