For
metal, the most popular type is brass strip, sheet, or wire. It works
well for this sort of thing. You can also use stranded copper wire found
in power cords and blackened annealed steel wire. All of these will
silver solder and they can be chemically blackened or otherwise painted.
I have made hooks and eyebolts out of the thin copper wire down to very
small sizes, some hooks as small as about 3/32” long. The blackened
steel wire is readily available in very small gauges and is quite good
for soldered hooks etc in 1/96 scale and larger.
Rather than try to show you how to make every joint that you might find
useful in ship modeling, I think it would be better if I showed you some
basic tips on how to make “a” joint. If you can make a simple joint,
then you can make any joint. In my experience, there are two keys to a
good hard soldered joint. First, the pieces to be joined must be clean
and bright. Second, the two pieces must be in perfect contact for the
joint to be completed. I know I have said these things so often it
sounds like a broken record, but that is the long and short of it.
The cleaning part of it can be done with chemical pre cleaners, but for
my work I have never used them. I have always been able to file up the
pieces until they are clean and bright and that has been enough. I know
several very fine and experienced modelers who swear by the pre cleaners
so I will leave that to each modeler to decide.
Getting the pieces in perfect contact sometimes requires some thought.
The best advice I can give is to try and let the tension in the metal
work for you. This is accomplished by over bending the pieces and then
springing them back so they are forced, by their own tension, to touch
each other. That is much easier than trying to force them together when
their tension wants to hold them apart. Even with brass that has been
annealed, it is often difficult to simply bend the two pieces towards
each other and have them make perfect contact. The best way is to over
bend the pieces and then spring both pieces back so they will be forced
against each other.
Well, let’s make a simple joint. We will make a loop such as is needed
for an eyebolt, shackle, or a hook. There are two reasons for using this
simple joint to illustrate the process of hard soldering. One, they say
it is best to walk before you run. This simple joint is a good starting
point for soldering. Two, this simple joint has everything in it that
any other joint will have. If you can make this soldered joint, you can
make any soldered joint.
We will begin with a roll of 24 gauge brass wire. Snip off a piece about
6 inches long. Holding it in a pair of cross locking tweezers or your
pliers, anneal the piece. I use my trusty kitchen stove. Light the
burner and hold the end of the piece in the flame until it glows red.
Once it does, remove it. After it cools, use your pliers to bend the end
of the piece back across itself. Place the pliers about 1 inch back from
the end and bend that outer leg so it crosses over the wire. You can use
the shank of a drill bit as a former for the loop you want to make. Now,
you have the free end of the wire crossed over the standing part of the
wire that you are holding. With the looped formed, pry the free end of
the wire out a bit from the standing end of the wire so you can use your
end nippers to cut off the excess part of the free end. Again, over bend
here just a bit so after you snip off the excess, you can pull the free
end of the wire back a bit and have it close up against the standing
part of the wire.
