The cord in question is similar to the cord which operates the blinds on
your windows.<br>
It is a multi strand core with a woven covering. To facilitate the
threading of the cord in<br>
the flange, it is necessary to attenuate the leading edge.<br>
<br>
This is accomplished by the method described be Bill Spurlock:
(paraphrasing:)<br>
Peel back the covering a bit and pull a few strands out 1/2" or so.
Pull the entire<br>
group of strands out another 2". While securing this end of the
covering and strands,<br>
slide you hand along the covering to allow the other end to extend beyond
the strands.<br>
<br>
This will produce a narrow leader to thread through the flange. The
reason to pull a few<br>
strands through first is to allow a gradient to the cord substrate.<br>
<br>
Pull the covering tightly and apply CA or hot glue to solidify the
narrowed covering.<br>
(spring clamps at each end and hang until dry). Trim accordingly.<br>
<br>

(WOVEN jacket cord?) As opposed to what kind of cord? And what size do
you<br>
drill the hole in the flange reletive to the cord (my flanges had the
metal<br>
center pins)? I would assume just the "right" size? Just
to make it nice<br>
and snug, but not requiring desruction of the flange when trying to pull
it<br>
through, i.e. just snug enough so that it won't fall out?<br>
<br>
Thanks.<br>
