"Wippen" (was "Whippen" cords)

[Roger Jolly]

>As for the chords, I agree with Wim

Perhaps the incorrect spelling, for a spelling cop??????

I would not recommend CA glue for gluing the silk cord, it will wick into
the material and rob it of the flexibility.  Hot hide glue would be
followed by white glue for field repairs.

Regards Roger.


(not "Whim"), basically.  I highly advise
