Default Soft soldering.


I have 4 brass hollow balls that need parts soft soldered onto them,
they are highly visible as they are part of a Harrison H1 type clock,
is there some compound or barrier that will stop the solder flowing all
over the place, i once read about Tipex but not sure if this is good for
soft solder, regards Dave

David,
B****** Computer is going mad but simply use a soft pencil to shade
around your solder joint.

Paste solder! It's a mix of solder, and flux, sold by jewelers supply firms.
Use a light smear on one part, assemble, wipe off any exess, and heat. It
makes a nice neat joint

David,
Steve's solder paste is the way to go but it does not
prevent the solder running which is your question.
I have actually done this type of work leading car panels. I have also
used it in silver soldering and brazing.
Obviously, there is a proprietory 'shield' which does a similar task.
However, this ''lead pencil' stuff is straight out of Newcastle.
Following the logic, and my wife has a Dip.Orth., One uses powdered
graphite as a parting agent in casting. 'Lead' pencils are graphite.
OK, me old son?
I could have said 'Tippex' but where the hell do you get a typewriter
to get Tippex these days?

But the parting powder used in casting is to stop the two layers of
moist sand sticking together, not the metals ! Graphite compounds are
also used as a 'slick coating' on sand moulds to improve the surface
finish, usually in an alcohol carrier that is 'flashed off' with a
flame.

Tippex is perfect for soft solder.

You could try one of the solder pastes (used for SMD's) applied
sparingly inside the joint faces only, then a dry(not loaded with
solder) hot iron right on the top of the part being afixed, but be
aware solder will try to flow towards the scource of the heat.

Is the wall thickness of the ball too small to allow a mechanical
connection (tapped hole/screw)?

Another alternative is adhesives rather than soft solder - Epoxy for
example. Rather easier to control where that goes, and to clean off
any excess.

If its good enough to attach the wings to a modern aircraft it should
work well enough to hold your balls in place ;-)

Tony

As I seem to live closest to Dave, does this mean that I have to
inspect his balls?
I don't fancy the idea of applying e- poxy- resin and Dave seems to be
in two minds about them being blacked.

Should we suspend things until more research is conducted? There seems
to be more than one drawback!

I hope my aircraft that I will be flying in soon won't have its wings attached
with glue.... :-))

I'd be much more concerned if they weren't attached rather than were
attached !!!!

Peter -

Better quit flying in that case!

Seriously, modern aircraft are making increasing use of composites,
held together with high tech adhesives. The latest Boeing 787 claims
to be 50% composite materials (for "composite materials" read
"plastic"). See:

http://www.boeing.com/commercial/787...ackground.html

So soon you can fly in the modern equivalent of an Airfix kit <G>

Tony

Hi Tony, the balls are spun brass, at a guess about 20 thou thick, i was
thinking of silver soldering them but there is a big difference in the
mass of the parts to be joined, the danger would be in melting the
ball! Hi Norm, you can come round and look at my balls anytime, just
have to wait till my wife comes home so i can ask her where she put
them, Dave
