For
several years I use to a home-brew tool, that I made by myself,
for puling guys. I made it of 8 mm of steel plate. The tool holds
any guys, for example,
|
bimetal
of diameter of 4-6 mm, steel rope, wire rope. Picture shows how
the tool holds the guy.

A
winch is attached to the hole in the tool and placed by the place
where the guy is fastened.
You
can very easy move the tool onto a guy. The tool does not bite
a guy at pulling. When a guy has been pulled, the tool removed
by unscrewing the bottom plate.
|
Everyone
can design the tool to needed sizes, proceeding from own needs.
Force of capture is defined by a difference of shoulders of cross
levers to which fasten plates. Plates have longitudinal gnowing
-through at the place where it hold a guy.

When
experimenting on the LF-band chokes with inductances of some mH
are often needed. They are not so easy to get in these days. Those
in the junk-box from the tube era are often quite big.
Do
you have low-energy lamps that are not working any more ? Before
giving them away to recycling do the following:
Carefully
disassemble the electronic part with a screwdriver. Inside there
(among some other things) is a choke with an inductance of 1.8-17mH
(depending of the power and the make of the lamp). They chokes
are very small, approximately
|
12x12x15mm.
I have measured the Q of some of them and it was between
10 and 25.
Caution:
Yes, of course you have to be careful not to apply any force
on the glass part of the lamp. I have taken between 5 and 10 lamps
apart and used the method of holding the socket with a glove firmly
against a piece of wood. Then using a small screwdriver to carefully
bend the socket into two parts. By doing in this way no force
is applied to the glass. When the socket is divided into two parts
it is an easy matter with a small sidecutter to cut the wires
going to the filaments.
Happy
recycling !
