chickering surprise

[Ron Koval]

Hi all

I've got a old chickering grand I'm regulating.  I ran into something to 
watch out for in the future.  The main complaint was that the piano was real 
uneven.  This action had some work done years ago. (new hammers and a few 
replacement parts that didn't match!)

So the surprise for me was that the single repetition spring was a double 
string attachment, not just into a slot. (one on the jack, the other on the 
balancer)  The previous tech must have worked from above to strengthen the 
springs, and missed the string loop.  About 30% were out, causing all manner 
of strange friction readings.

Hope your weekends are enjoyable!
