[CAUT] pinned agraffe

[Paul T Williams]

Our '56 Baldwin D was a mess of false beats, no sustain at all, and the 
whole mess.  We did a Wapin retrofit and I installed Ronson Wurzen hammers 
and new wippens too.  It came out wonderfully!  I would like a bit more 
depth in tone (in my ears) but everyone here loves the improvement. Beats 
a new board and bridges, eh?

Thank for your post Don – putting this issue into its larger, proper 
perspective. But one quibble.

>The tonal change is not dissimilar to doing Wapin bridge pinning, at 
least to my ear – brighter and thinner tone with a little more sustain.

This has not been my experience of Wapin at all. This past summer I 
installed a Wapin bridge on a Kawai GE-1 that had many bridge termination 
problems, as well as a weak and noisy treble with little or no sustain. 
After the Wapin treatment it now has a much fuller tone espcially in the 
troublesome capo regions of the piano. There have been some Wapin 
installations where I didn’t notice much difference, but this one was 
clearly a benefit, and more in the treble than the bass. 

Now, of course, I cannot answer the question, would this same benefit have 
occurred were I to have simply repinned the bridges and solidified the 
pins with epoxy. It’s never easy, for us in the field, to draw conclusions 
based on one-off applications. Maybe better to not reach for a conclusion, 
just keep eyes and brain open to possibilities.

The tonal change is not dissimilar to doing Wapin bridge pinning, at least 
to my ear – brighter and thinner tone with a little more sustain.
