Hi,
I can appreciate the dilemma of soldering a bezel onto a textured
piece of metal. There is a wonderful product called Stop-Flo. I
use it all the time to keep the solder from going into the little
crooks and crannies of the textured silver. I, of course, solder
with paste solder matched to the temperature that is most
appropriate for that part of the project. If you have other items
or findings to be soldered onto this piece you can use easy solder
to solder the bezel to the back textured piece (use hard to solder
the bezel together so it does not open when doing that step) and
save the extra easy for the last step as it does melt at a lower
temperature than the easy.
When using the Stop-Flo, just paint on with a paint brush all
around outside the bezel, but as close to the bezel as possible.
If you place this any where under the bezel, it will not allow the
solder to flow in the area where you have painted it… That is the
whole idea, so be careful of placement. It is a fairly quick drying
liquid. I buy mine at the Mine Shaft in Pompano Beach, FL
800-654-3934. They do ship. (No affiliation).
This is wonderful product since it will wash off at least 85%
easier than yellow ochre after it is heated and at least 100%
easier than the white out everyone touts, it is also non toxic. It
is not exactly cheap, but to me worth every penny. You can leave
it on, if you do not have to solder an area where you have put the
Stop-Flo, until ready to pickle. There is no residual left in the
pickle. You then rinse and gently scrub with a soft toothbrush.
Takes just the most gently of rubbing to get it off.
Happy soldering.
