Broadwood Rectangular Tuning tip

[Maxpiano@AOL.COM]

Lance,

You're welcome for the suggestion.  Did you say you have seen the piano?

Those Broadwood grands that I have worked on in the past have not only had 
oblong tuning pins, but the pins instead of having the fine multiple threads 
of our standard tuning pins, have coarse sharply defined threads.  Rather 
than the holes in the cast iron being larger than the pin, they are small and 
tapped to fit the thread.  Invariably, I have found slipping tuning pins. 

Since there was no opportunity to use oversize pins, I was stumped on the 
first one.  It appeared someone had already treated the pin block by turning 
it over and treating from the underside.  The treatment no longer held.  The 
customer eventually sold the piano.

I am not keeping one up that I treated with thin CA after removing the felt 
collar around each tuning pin.  Used no accelerator.  The pins now hold 
acceptably.
