[pianotech] bass strings installation / coil direction

[David Love]

If it's a set, look at the larger strings where you can see it.  Different
string winders go in different directions.  You can also ask the
manufacturer in which direction (clockwise or counterclockwise) the twist
should go.

Subject: [pianotech] bass strings installation / coil direction

 

As long as we're on this subject, I'd love to hear from ya'll on this one:
When replacing bass strings in the field and putting that final twist in the
string, I've always relied on my Clark Kent vision to look at the end of the
winding to reveal which direction the copper winding is going.  ... Last
week, I replaced an uber-fine bass string on a CP-70 and it's winding
direction wasn't immediately obvious.  I put on reading glasses, still
questionable.  I got a magnifying glass and after a couple of minutes
finally determined the direction.  It was NOT, as it happens, the same
direction as the original strings on this beast.

SO... I humbly ask my colleagues -- short of lugging around your handy
electron microscope, as was needed in this case -- do you have any tricks
for determining coil direction?  Is there a different method to each
manufacturers madness?  (In this case, it was Mapes.)

Thanks, ya'll,
Jim Wilson
