    Lee, I have done a few that size and larger. I used the tripod and
    heavy wire screen. I use iron binding wire to gently hold the bezel
    down to the flat plate. Use a lot of paste flux. Then position all
    of the solder chips and warm up to evaporate off the water.
    Reposition chips as necessary. The trick is to use two torches
    (Smith or Prestolite type) with large tips, #s 4, 5, or 6. Set for a
    large soft flame. You may need to back off the regulator a bit. On
    with one torch under the wire set a little stronger and one on top
    set softer, I bring the whole piece up to temp evenly. This really
    helps keep that large sheet from buckling as it expands. It is just
    like rubbing your head and tummy at the same time. You want to do
    this with a lot of people watch as it greatly enhances you image as
    master miracle worker. In the really massive cases you can bring in
    a helper to hold one torch. It is also possible but not recommended
    to hold one torch under with one hand and two torches in the upper
    hand. This is for those really desperate, now jobs and you are
    alone. Also consider kiln soldering. Works but not as exciting.
