Marco's frame in progress. Rear wishbone triangle, previously brazed complete with topstay/wishbone/seatstays, is now ready to braze to the back of the seat lug and to the dropouts. The mitre angle between the seat tube and the top stay has been determined directly from the Marchetti brazing fixture and the topstay cap was mitered and then brazed to the topstay. All that remains is to silver braze the topstay binder to the back of the seat lug and the seatstay tips into the dropouts.
