Hello again,
Well, when you twist the wire ends together that gives it the mechanical
support it needs while the wire glue is drying. It's that simple. First
strip maybe 3/4 inch from the ends of both wires to be joined, then
twist them together maybe 5 turns or more. That puts them into
good contact to begin with, even without the wire glue. Then, dip
into the wire glue container and that coats then entire joint. You
will then have to give it time to dry during which time the joint should
not be moved at all.
The next step, should you want to add more mechanical strength, is
to add some 5 minute epoxy over the wire glue, plus a little more
over the leads that still have insulation. This will add to the mechanical
strength despite what that eBay'er said. Just make sure the epoxy
also coats some of the leads where there is still insulation.
The more epoxy the better here, and another idea is to tape the wires
before the epoxy dries to something solid, like the guitar wood sides or
bottom. Two small pieces of tape even better, one on each side of the
joint (not over the joint). This will hold the joint with epoxy onto the
wood which when dry will keep the joint from moving. This wont always
be possible of course, when the wires are not long enough to allow this
or they have to be able to move after the repair anyway.
If you are really concerned about the strength, after the epoxy is
applied before it dries wrap several turns of heavy duty 'coat' thread
around the joint. The epoxy will soak into the thread and form a nice
solid mechanical structure. You can even coat the joint a second time
with the epoxy to get a stronger joint.
Let me see if i can draw a picture of this...be right back...
