tech problem: something with foil causes white light

Post by Jean-Charles Gregoi » Wed, 11 Jan 1995 13:56:34


        I have been fencing for many years and have been able to fix all
my technical difficulties with my foils up till now;  both of my foils
have the same problem;  the barrel is loose.  I fix it on a vice and then
I tightly tighten the barrel as hard as I can with pliers.  Then when I go
to fence, after 2 min. my barrel becomes a bit loose again, and that
causes the white light to go on the machine.  I then tried to, after
tighening it, glue the barrel with the foil (using the glue I use to glue
my blade wires to the foil.  It is a rather weak glue;  nothing like crazy
glue.).  This allows me to fence for 30 min. before the barrel goes loose
again.  Either I don't tighten it hard enough (I try as much as I can), or
the "screw paths" on the foil are broken, or the barrel's "screw paths"
are broken.  What should I do?  I have a very important competition coming
up in a month and I would like to know how to fix this problem because I
can't fence electric with it.  The best I can do is fix it for 2 minutes.
What do I do?

If you've stripped the***or the tip by overwinding, then you're
probably screwed, no pun intended.  The barrels usually take a lot of
vibration stress, and what seems like overtightened will quickly vibrate
loose.

What you need to do is put a small (very small!) drop of SuperGlue or
Loctite on the***thread.  Not enough that it wicks into where the
spring/cup assembly is, but enough to moisten the "screw path" as you put
it.  

The little bit of chemical help keeps the barrels from coming loose, and
if you ever need to remove the tip, its still ok as the drop of glue is
easily overcome with a pair of clamps etc.  

Remember to orient the blade, tip up during the drying phase, so that any
possible excess runs downward, and not into the barrel.

I always use crazy glue on the barrels of my foils to avoid this kind of
problem.  It makes it a little messier when it comes time to rewire the
blade, though.

In your situation I run would try to run a little crazy glue under the barrel
and then tighten it fairly tight with pliers.

Good luck.

I've found that some foil blades have rather large shoulders between
the threaded tip and the body of the blade.  Compare these two defective
blades with a blade that doesn't have a loose barrel problem (even a broken
one).  If the shoulders of the problem blades appear larger than the good
one, there's your problem.

If you look inside the barrel (from the threaded side) you will probably `
see a space of about 1mm before the threads start.

If the shoulders of the tip are too wide to fit inside this space (at the
base of the barrel) then the threads aren't getting a full grip. Loc
Tite or super glue won't help.

You can use a barrel that has threads beginning at the bottom (some
German barrels are this way), or you can use a fine file to carefully
remove some of the excess metal from the shoulders of the weapon, being
careful of the threads.  I have had to do this to many Russian blades, and
quite a few Chinese blades.  I've seen it in a few French blades, recently.

I would rewire the things, this time using blue LocTite on the barrel threads
before tightening.

If it were only for club use i would try red LocTire and retightening.  Since
the meet is a month from now that might be worth a try, but it wouldn't be my
first choice.  Do untape before tightening a barrel if you decide not to
rewire, lest the tape's elasticity attempt to loosen the barrel.

LocTite can be gotten at auto parts stores and hardware stores, at least in the
US.

If you wish to fence electrically in competition, get a couple of
NEW BLADES, install them in proper fashion and check them out before each
competition.  The problem you are having with continually loosening tip
is probably due to improper threading of the blade.  DO NOT USE ANY TYPE OF GLUE
TO SECURE THE SLEEVE to the end of the blade. The glue will insulate the sleeve
from from the blade causing a break in the normal closed circuit, hence the
"off target" white light.  

Either learn to rework the blade threading yourself with proper tools or engage your local
division armorer (or a competent equipment supplier) to rebuild your old
weapons.

Good luck!
