>Do/did some manufacturers bore their upright hammers >such that the hammers overstrike the string... Yes, supposedly for the whip of the shank to flex and the hammer strike perpendicularly. Evidently, most player don't use that much force; so I bore hammers to understrike just a bit so that they will wear in to perpendicular and not spend their life going further and further away from ideal. Same for grands. Recently did a 40" S&S console, had to shorten the shanks to maintain strike point. the original hammers had a definite overstriking wear pattern, flat and highly angled. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
