V-Bar question

[Farrell]

I have never seen a V-bar on a vertical that was not part of the plate casting. I have, as Wim describes, seen rods that sit in a groove in many verticals. However, on many grand pianos I have seen a variety of string thingees - mostly duplex-type things that just sit on the plate - they are not part of the plate, nor do they sit in any kind of groove. Once properly positioned, they seem to stay quite well. I often eliminate front duplex hardward and replace with a half-round brass piece that I do glue in place, but I think mostly is held in place by string pressure.

My suggestion is to determine the proper position of the V-bar, temporarily tack it in place (tape? glue? wedge of some sort?), string it and you will likely find that the piece just sits wherever you put it - just like duplex aliquots do or my half-round does.

      I'm writing for one of our sight impaired chapter members who is having trouble restringing a 36" Sabel 85 note vertical c.1953, European.   He indicates the treble V-bar is not cast into the plate and is free to move around.  His question is how does the V-bar remain in one place as he puts tension on the strings?  It seems to be shifting as the strings are brought up to pitch.  Does string pressure alone keep it in position?  Does the pressure bar have any bearing (pun) on this?  Anyone run into this before?

  I wonder if he is talking about a rod that fits into a groove, similar to some grands that have this kind of set up. On the grand, however, there is a slot into which the rod is held in place. I use masking tape the hold the rod in place until after a couple of strings are put on. But on a vertical, the masking tape might not be strong enough to hold the rod in place until the strings are put on. This might a 2 person job. 

  Just my 2 cents worth.
