[Land-speed] Plating

[Robert J. Denton]

Dick, I'm a gun collector. Specifically Colt Single Action Army. (cowboy
guns). I went through some stuff for you. Here is the recipe.

Glass container, big enough for the part to be deplated, suggest small parts
only, not bigger than pistol parts.
Batteries, 12 volt, can use two in series,
Cables, insulated with good contact at the copper rods and at the battery.
Copper rods, connect to cables for cathode, lead plate (-) and anode, part
to be deplated (+).
So3, sulphuric acid, one gallon of acid to one quart of water.
ACID IN TANK FIRST, ADD WATER TO THE ACID SLOWLY
All other acids add acid to water base.
Cathode,-(neg) lead to lead weight or sheet with a surface area that equals
or exceed surface of the gun part to be deplated. (can be a lead weight)
Anode, to pos. of battery to gun part to be deplated.
This process will deplate nickel, chrome and cadmium, but not gold or
silver.
Stripping time is from 5 to 10 minutes.
Switch, on-off to prevent spark.

If the acid is not stored in a sealed container, leave room in the
container, (so3) acid absorbs water and will increase the quantity in the
open tank and as a results the solution will be weakened.

As the battery discharges, (water separates H2S04) oxygen and hydrogen is
given off as 2 gases and to reunite a spark is required. When the two gases
ignite, there is an explosion, if this occurs at the battery, the battery
could become a bomb of sorts.
Do not smoke around the battery, do not make sparks when making connections
at the battery.

Safety glasses and gloves, use them.

2 Batteries (12 volt) in series, increases the voltage by 2=24 volts, the
amps decrease if the work to be done stays the same.

Series connection, positive of one battery is connected to negative of other
battery. This leaves two unconnected post, one on each of the batteries, as
a results connecting to the two remaining post makes a circuit. Without a
way of controlling the flow of electrons, it is a dead short and will melt
the wires and could cause the batteries to explode and or cause a fire.


Probably best to get a chrome shop to do it for you.
