v-bar/capo repair

[Delwin D Fandrich]

Drill through and install spring pins. Or simple bridge pins. It doesn't take
much.

I had a problem keep a length of brass half round in place. I'm interested in
knowing what people use to make sure it doesn't move.  It was a longer piece
that extended the entire treble area.   It was a slippery little thing that
moved when the tension was brought up to pitch.

Hi David,

 

When experimenting duplex length with brass half or oval round, would you, in
this case, place anything on the bottom of the brass to avoid scratching the
plate?   Or isn't it a problem?

 

Thanks,

 

Barbara Richmond

Like Ron N. says, I think it's likely it has to do with the front duplex and you
may be able to shorten, detune and increase the deflection angle by inserting
some brass of appropriate dimension-at least you can experiment.  If it turns
out that that's the problem, it's not that big a deal to remove the strings from
one section and insert the new counterbearing piece and then replace the strings
(the same ones you took off).  Unhook them from the tuning pins slip in the
brass or whatever and then reattach-if that proves to be the problem.  I get
brass of varying sizes from www.rjleahy.com <http://www.rjleahy.com/> .  They
will cut to a reasonable shipping size.  I don't know the configuration of this
piano but maybe you can send pictures and some suggestions could be made by
various people, I'm sure.  If the noise disappeared originally by muting the
front duplex, it is likely that there is leakage occurring and that's what you
should address.  Shortening the section and increasing the deflection can do
that.  You do want to be sure that the angle and deflection work together.  The
longer the duplex the greater the deflection angle.  Similarly, a shorter duplex
requires smaller angle.
