This is my second complete bike frame, and first mountain bike.  I started building this frame last year (2013) and totally fubarred the main triangle so I scrapped it.  I finally got around to giving it another crack and overall in the spring of 2014, it turned out reasonably well.  This was my first fillet brazed frame and that was a lot of work.  As I was initially laying ugly fillets and then filing and sanding them, I thought to myself I never want to do this again.  Shortly after I finished though, the desire to master fillet brazing really took hold so I think I will be doing some…
