Brian- I've always felt that the evenness of the temps within the joint is very important. I've read that the time spent at the brazing temp is also a big factor in how much material characteristics possibly change.
When you see the production pros with big torches/flames I see the "power" to bring the joint up to the right temp to do the brazing quickly, not to get the joint any hotter then needed. But the balance between joint temp, it's evenness of that temp, and the time it takes to do the actual brazing is where skill shows.
As to the vid... there are more then one way to build a frame. Some that we wish we could afford and some that we wish to avoid. When I saw this a few years ago I had my moment of disbelief. Andy
