Fw: hammer replacement

[Erwinpiano]

    Wiw

 Please no offense but that advice is a recipe for getting just exactly or
probably the wrong bore dimensions every blessed time.Ask me how I know.
It's o.k. to send them hammers and shanks for angles maybe but  string
heights and center pin heights vary as do the accuracy of the original
boring. Measure the center pin height from then  Measure string height in
each section.Subtract center pin height from string height and it' that
simple and no disapointments later. Ding it the other way is a good way to
possibly compound errors and end up with a mess that won't regulate!  Take
measurements.

  Also,  Ask for Ronsens. It's a better hammer.  Just my opinion and the
flame suit is on.
