When I take out my spring from my foil, the little wire head often comes out
with it! The wire is then useless. Why does this happen?
Jean-Charles Gregoire, | . o c ,
When you wire a foil you solder the wire to a the flat side of the
contact. You then thread the wire through the plastic "cup" in which the
contact is supposed to sit... The wire should be soldered in such a way
that no uninsulated wire is exposed below the the insulating contact cup.
I'm assuming that the old wire has been removed from the foil's wire goove
(as well as as much of the old glue as is possible - I scrape it out with
an jeweler's screwdriver - there are probably better and more appropriate
tools). Screw the barrel onto the tip of the blade, then thread the wire
(unsoldered end) through the small aperture in the barrel where the wire
grove is... If you sew and thread needles on a regular basis this will be
a piece of cake for you, but I don't sew and it usually takes me three or
four attempts. Gently pull the wire through so that the plastic cup, with
the contact sitting in flat side down, enters the barrel from the top and
rests in the bottom of the barrel. I usually use a jeweler's***driver
to ensure that it is firmly set in the bottom of the barrel. Glue the
wire into the grove (this can be an art in itself). After that, insert
the spring. Insert the point top, and... well if you got as far as
removing the spring before, you know the rest.
If the tip is assembled in this way, you shouldn't have any extra pieces
falling out next time you need to remove the spring. And hopefully,
you'll only need to do that if it gets too weak to pass the weight test.
Hope this helps.
(1) The wire had already become detached from the little contact.
(If this is the case, the wire was already useless - you just
didn't know it yet.)
(2) The spring is a little too small, and instead of sliding onto
the contact easily, it has to be jammed on. When you pull the
spring out, the contact gets tugged off the wire. This could be
caused by mixing different brands of springs and wires - they
are not all the same dimensions.
