The Bob Crump (Asylum) Power Cord
| (page 2) |
| Assembly |

This cord is very easy to assemble. The only
potential "complexity" is that you will have to
solder a bit. The IEC end requires you to solder the wires
directly to the metal connectors in the interest of improving
the contact between the two. The Schurter IEC has screws to
tighten the wire in place but the resulting contact is not
that good, hence the need to solder the wires on. If you have
never soldered before, or if you want to avoid soldering
altogether you may opt for a different IEC, like the Marinco
one used in the VenHaus Power Cord. But then (strictly
speaking) you are deviating from the "recipe" of the
designer. Personally I think the Marinco is a better quality
IEC but it's also more expensive. At the end you may not be
loosing anything if you do decide to use other IECs so feel
free to experiment.
The Belden 19364 is significantly more flexible than its
brother, the 83802 used in the other project. The 19364 also
sports a ground wire as an integral part of the cord, so you
will not have to wind an additional length around the cord as
you had to for the VenHaus Power Cord project. 19364 is also
shielded with an aluminum foil that conveniently has a drain
wire for you connecting needs. All in all it's an easier cord to
work with and one that will be ready "as is" for power
cord assembly. |

| Cut the cord to the desired length. In my case
I cut two pieces to standard lengths of six feet each. Strip
off an inch and a half of the outer jacket and separate the
color-coded wires within. Do this at each end of the cord.
Just score the cord and work your way around being careful not
to cut the internal wire insulation in the process. The
aluminum foil is very thin so you will probably cut that with
the outer jacket too. That's OK you don't need the foil anyway. |

At the wall plug end (Pass & Seymour plug
end) cut off the re enforcing rope ends but be sure to leave
the drain wire intact. The drain wire is the thin braid of
silverish wire strands that have no insulation around them.
This is because the drain wire is meant to be in contact with
the aluminum foil shield, and instead of having to twist the
shield into a drain connector you just use the drain wire to
the same effect. It just makes the whole assembly much easier.
Cut away one half inch of insulation from each wire exposing
the 14 AWG multi-strand copper wiring. Make sure you don not
snip away some of the strands in the process. Twist the drain
wire snugly around the ground wire strands. Twist the other
two as well so as to make them easier for insertion in to the
plug. Avoid twisting with bare hands/fingers, use gloves or
lint free cloth - this will prevent you depositing moisture
and natural oil of your fingers on to the copper strands. |

| Align and insert the wires into the plug making
sure they go fully in. Tighten the plug connector screws and
slide the back end of the plug into place. Close up the plug
and tighten the cord relief end too. |
