[CAUT] balancier/wippens report

[Ric Brekne]

Susan -
can you explain how loose pinning would create such a condition?

Hi David

I'm not entirely sure I understand exactly how this works either... but I can attest to the fact that it does. I have solved many a poor checking hammer especially in the lower bass by making sure the hammer center is on the tight side of acceptable...i.e. 4 swings and good on both bushings.

I THINK... its because the more unstable the hammers travel is the more likely it can find a way to wobble its way out of check.

However.... if I remember Wims earlier description... he was not sure that the hammers were even reaching the checks.  This seemed to conflict with the stated problem that no matter how hard he played the hammers would not check... but there were so many posts going back and forth I never  got a clear reply on that... or if I did I didnt notice it.

I'll be interested to find out what the end problem turns out to be.  I dont think it has anything to do with the balancier pin tightness myself.... but  time will perhaps tell.

Cheers 
RicB
