This is the aforementioned homemade carbon soldering gun.
The "D" cell battery carbon is long gone, and
I borrowed the large alligator clip that hooked up
to a 12v battery, long ago.
For example, I stuck a rod in the unit where the carbon
would go.
I haven’t opened up a battery in 40 years, but guessing
that it may be more difficult now days, and not
sure the modern battery carbon (if they even have them)
would work. Presume a person could find something
suitable without dissceting a battery.
quote Buccaneer:
In searching old threads, it was mentioned it was
problematic un-soldering the “hot” brushes from
the fields. Back in Vo-Tech in the 70’s, the instructor
had us all make a carbon tipped soldering gun,
that worked slick for this purpose. Basically, it
was a chunk of broom stick with a piece of all thread
inserted through it. On one end a wire and alligator
clip was attached, on the other end, a nut with a set
screw was welded to the all thread. In that nut
was the carbon (which we removed from a D cell flash
light battery. You’d hook up the rig to a 12 volt battery,
(and a ground wire from the battery to the starter)
and that carbon would get “red hot” when touched
to the brush retainer, melting the solder in a couple
of seconds. I’ll have to look to see if I still have this tool.
Thanks!
