Schwander return spring loops

[Bruce Browning - The Piano Tuner]

List,
If you replace the flanges on the first job, this gives you a spare set to
replace loops at your leisure.
Sort of one-ahead principal.

>       3) Most Yamaha consoles have flange plates, so you can leave the

> butts/hammers.
>       4) Use a thin saw blade to scrape out the silk cord from the slots
> in the flange.
>       5) Use a 5/8" dowel and wrap your new cord (recommended "spiderwire"
> ) fishing line around it, then slice all the loops at once with a
> razor blade.  The diameter of the rod makes the loops uniform size.
>       6) Use your glue of choice to secure one end of the loop to the
> flange slot.  Go back and glue the other side.  I've used CA gel
> glue, using an accelerator.  Sets up fast, but use care it doesn't
> gum up the flange bushing or leave buildup on the flange surface
> that will interfere with the butt when you reassemble it.  I've also
> used pvc-e glue.
>       7) Reassemble the butts/hammers, bridle tapes, rest rail.  Done.
> I'd estimate 4-6 hours.
>       Play some music or books-on-tape while you do a tedious, boring job.
>  Have fun.
