A few things I would like to contribute here.
Regarding tips for the littletorch…I have hogged out a number 7
tip so that I am able to solder cuff bracelets of some size, several
ounces. Its not the prettiest flame but it works.
Screens…If you have a tricky soldering task, heating through a
screen from the underside is working blind to some degree. The
backside will become hotter than the front because it stands between
your heat source and the area you wish to solder… you may overheat
your back surface because you can’t see when its at that dangerous
point. Soldering upside down is totally blind
What has worked for me is a compressed charcoal block (they don’t
break the way soft blocks do when heated a lot) and from the top,
circling the flame around the piece, spiraling in as the temperature
of the object rises. Watch the flux carefully, as this is the
indicator of temperature. You will see it bubble and then settle in
shortly before the flowpoint of solder is reached. If you need to,
put a heat shield such as a coin on the top edge of the bezel. The
bezel would tend to melt from the edge downward usually. The heat
shield will both deflect the flame and draw heat away from the
’nervous’ edge. Solder flows toward the heat so try to keep the bezel
cooler than the base until proper temp is reached, then play the
flame directly at the join.
If the bezel did partially stick, before you try soldering more,
remove the bezel completely and file the mating surfaces. You need to
physically remove the oxidation that has accumulated on the mating
Flux…Batterns and similar thin liquid fluxes will burn away. Try
Handi-flux (paste) for those jobs requiring a lot of prolonged heat.
On a tangent…Handi-flux is pretty good at cleaning diamonds (but
ONLY diamonds) you have accidentally started to burn. If they have
turned black from not being completely clean but not yet frosted,
pack the stone with Handi-flux, heat to liquefy and pickle. May have
If your bezel melted when you were doing the JRs, you were just too
hot. Working from the front you will be able to keep an eye on your
Hope you find this useful.
