Front rail punching change

Hi Barbara,
                        This problem is quite endemic on many piano 
brands.  The last few years I have been using my Yamaha reaming less 
frequently, and the height reaming tool far more often.  You will 
only have to do one piano to be a convert.
I make it a habit of checking every piano that I pull the stack.  You 
would be surprised how many times I end up looking like a hero ;-)

On Grands, I have found it has an effect, on dip, after touch, 
checking height, and repetition.   Most common complaint from 
customers is that the action feels heavy.   It's not so much heavy, 
but the fingers really feel the resistance at the let off point, as 
the BR pin starts to bind in the hole.

On some pianos, after reaming, I have had to  steam the BR hole to 
get rid of some chucking.

A Golden Nugget of advice:   Check the height of the hole, before 
enlarging the hole.

Regards Roger
