This is my second attempt at brazing on such delicate material and I have a question. To keep the bosses straight do you use a jig or did it get better with practice? I made the holes so I had to push in the bosses rather than just fall in, I filed out the holes on the strengthening diamonds so they fit around the head of the boss and then proceed to braze everything. I am mostly pleased except for one of the bosses if off a little. Not that it will be noticed but I will know it is there. I even managed to fill in a couple dings on the top tube.
