Now the black wire will be soldered to the bottom center of the ribbon element. What I did was pull the wire
back out, and trimmed, stripped and tinned it. The red wires will go up the channels on each side of the bracket,
and to the center top of the ribbon element. What I did was push them into the channels, sorted out where
center approximately was, and then trimmed, stripped and tinned them.

You are now ready to install the ribbon element.
Putting the Ribbon Element (Motor) together
15.
Ribbon Motor – Follow Rick’s instructions (pages 9 through 13 of his instruction PDF) for building the motor.
Glue the two magnets in using the spacer, with the proper polarity. Remove the spacer when dry. HOWEVER,
do not solder the connection wires to the motor. You will solder the motor while it is in place. But you can tin
the copper. But remember to mark the back of the body with a nice red plus + sign to indicate the plus end of
the element. It will make things easier later.

Prep for dealing with the Ribbon using the cutting guide PDF
a.
Use the ribbon pocket guide to 1
st
cut a number of pieces of parchment paper. This will create 20mm
wide strips. First cut a strip of parchment paper to be about 145mm wide. Tape the cutting guide onto
the piece of glass, and then tape the parchment paper on to the glass on one edge, and using a steel rule
(cork side up if it has it), using a brand new exacto or razor blade, cut them into strips. These will give
you 20mm wide strips, which are around 145mm long. Then fold them in half long ways. You will use
these as pockets to place the recently cut ribbons into them.
b.
Select and cut the ribbon cutting guide. There are several difference sizes to choose from. The closer
the ribbon is to the magnets the better, but you don’t want the ribbon to actually touch the magnets.
While Rick suggests basically a 4.75mm wide ribbon, I’ve found that using the ribbon alignment jig, I was
easily able to keep the ribbon centered, and have been able to easily do 5mm and carefully 5.25mm
wide ribbons. So pick the ribbon cutting guide you want to try, and tape this to the glass.
