Hi- I don't think it's more momentum that allows the hammer to check, but that the hammer comes down to the backcheck much later thereby allowing not only the backcheck to be slightly higher, but also the jack to be more out of the way of the knuckle. > >Ed asks an important question here. If you don't use a string height gauge, >the hammers, when played, will go up further than they do in the piano, and >have more momentum coming back down into the backcheck. Thus, they will check better on the bench. -- Vince Mrykalo RPT MPT Senior Piano Technician Crane School of Music
