After tiging the top strap...use High force 44 low temp solder from Brownells as sweat solder...lightly scrape the the surface of the old solder, use flux, read the instructions..,pound a 1/4" bit of solder into foil, repeat for both sides of the loop...place the foil (with flux) between the sweat faces,leave a little sticking out so that you can read the solder as soon as it melts...apply a little pressure to the loop...heat only the loop with a pencil torch (or a larger torch via a heat sink) until the sweat solder melts on both sides...remove heat...when it cools, clean off the excess flux residue and remove excess solder with a small wood chisel...high force 44 has a critical temperature much lower than the solder used on the ribs
