Broadwood broken tuning pin

[Gevaert Pierre]

Hi, 

 

The Boudoir grands I know about have the (square)pins screwed for about 2/3
into the iron plate and 1/3 into wood.

I tuned several and some stayed in tune quite well (afther more than 130
years !)

Others had the pins to loose. I don’t know if it is possible to find such
tuning pins nor if it these would hold better.

There is some explanation on the lest front side of the soundboard near the
basstrings but I think this is only to explain how to change a string.

 I’m also interested to know how to make this kind of pins tight again.

 

Like some use ca glue for wooden pinblocks would it be possible to use a
kind of product like Locktite for metal threads ?

This is used for making the threads tighter and exists in several strenghts.


Of course this may sound stange for using this kind of stuff for historical
pianos but I can’t see another way exept maybe make threaded pins that are a
little bigger or maybe a better choise to change the wooden part of the
block (beech)so that at least the pins get some new grip there.

 

In this way it would be possible to clean and reuse the original pins.

There are many of those Boudoir grands remaining today so I would eventually
be possible to find another similar instrument for using spare parts.

Are you talking of the threaded pins that screw into an iron plate? 

If so, send a photo.  I can't help you but I'll be doing some work 

with a colleague soon who may have some.
