Hammers

[Tony Caught]

So OK, I neglected to say that the pianos also go out of tune whilst I am
tuning it. And that under these circumstances it is virtually impossible to
tune a piano properly.

Both spruce and pine are both soft timbers, cut on the quarter which
promotes swelling of the soundboard.  The soft timbers will of course accept
moisture more rapidly than had woods.

Have a photo that I will send (when I get a scanner) of a Yamaha bridge that
opened up on a glue joint you would love to see. (Yamaha replaced the piano)
The piano was 8 years old.

If you look at the bridge joints in Yamahas you will notice that in most
cases the glue joint is very dark, waterproof glue. As against the lighter
colour joints in their non tropical pianos that are not waterproof.
