DIY etching tool electric engraver project for electroplating and stencilling

electroplating stencil, engrave into metal with electricity, electric engraving toolCheck out this old school electric engraver diy project kit.

You can easily—and safely—put electrochemistry
to work “branding” your name
on tools, or decorating aluminum sheets.
The stencil pad consists of a metal plate
(copper, aluminum—even a scrap of tin
can) covered with felt that’s saturated
with a solution of table salt (or with
liquid Sani-Flush).
Over this pad you smooth a section of
an ordinary mimeograph stencil (available
at any office-supply store) which you
have typed on a typewriter set for stencil
cutting, or with a hand stylus—just as if
you were preparing it for inking.
Clip the leads from a DC power source
to the stencil pad and the workpiece and
press the two together for 10 to 90 seconds.
This power source can be your auto
battery, a battery charger, or an electroplating
unit. Or, to use house current, you
can easily assemble a unit costing under
six dollars from a small transformer, a silicon
rectifier, a few feet of insulated wire,
a male plug, and two alligator clips. The
power needed is at only six to 12 volts low
amperage. I use a filament transformer
from Allied Radio (their stock number
54C1420) that’s rated 110-120 volts primary,
and 12.6 volts at two amps secondary.
I get about 12 volts, which speeds
up etching jobs.
I made two types of stencil pads—a oneliner
to hand-hold against tools and a
block against which metal plates can be
