<DIV style="FONT: 10pt arial"><B>Subject:</B> Re: Lubricating V-bar</DIV>
<DIV><BR></DIV>The other day, after having a wound bi-chord string break
during a 25c pitch raise, I touched the V-bar with some Protek for other
strings that looked a little rusty. I did my best to prevent creep into
the windings, but hey, who knows what might happen, microscopically and/or
over time. <BR><BR>I'm thinking maybe it's a good idea to carry a brass
brush (another ~50grams!?!?) with me for these pianos. Would it be ideal or
necessary to lower tension on the string before brushing the V-bar? If
so, should they be so loose as to move freely side-to-side? (I'm thinking
primarily bass strings.) Loosen a half-dozen at a time, brush, PR, lather,
rinse, repeat?? Brush parallel to the strings, or parallel to the V-bar? Take
precautions to keep rusty dust from contaminating the
windings??<BR><BR>Thanks,<BR>Paul Bruesch<BR>Stillwater, MN<BR><BR>
