Its going to take a ton of practice to get good at soldering an
I too struggled with overlay soldering for years! It never turned
out right…either too much solder flooded the seam or not enough
left gaps. That is, until I discovered the secret to perfect sweat
soldering. Now I get it right every single time, no matter how small
or large the job.
The trick is to prepare the back of the top plate to receive the
perfect amount of solder. It is included in my upcoming book, due
out in a few months. Here is a sneak preview from 101 Bench Tips for
Jewelers, which will be published later this year by AJM Magazine.

No Sweat Sweat Soldering
Use a pair of dividers to trace the outline on the back of the top
piece, leaving an inscribed border about 0.5 mm inside the edge. Use
a ball bur to carve away the surface about 0.2 mm deep, leaving the
border intact. Flow solder into the recessed area and then file the
surface, so that the solder and the surrounding edge are perfectly
flat. Place the item in position on the clean backing and trace it
with a pencil. Flux within the traced outline, then flux and
position the monogram. Heat from below=E2=80=94and watch with delight =
the top plate settles gently into place, with a perfectly even seam
