Thanks, Cy. Actually I eliminated the key from the equation by activating the whippen at the heel with my finger. There still exist some other possible causes: 1) the rep spring coil itself 2) rep spring segment where it enters the hole in the back of the jack Need to run some other tests. But the sound is most characteristic of a loose hammer head or center pin issue. The hammers seem to be quite solid on the shanks, and I did reinforce with thin CA (to fill any tiny unseen voids) followed by accelerator. Anyone ever popped off a glued hammer from a hollow WNG shank? On Tue, Jun 22, 2010 at 11:55 AM, Cy Shuster <cy at shusterpiano.com> wrote: > Any chance loose key leads are clicking?
