Here we have a Vincitore special shell being mocked up and worked on by Derek. As you can see from the picture the spear points are welded to the shell first then the tubes are brazed into place this helps stiffen the frame . The plates on the chainstays still have to be cut into shape at this point before the chain stays are brazed into position. The seat tube and the down tube also have to be brazed in at this point.
