The rollers (Renner) where originally glued on the shanks - parts that are from the generation 1998 or so, actual rollers are better, don't know what happens to these series. I rarely found the core slanted on new parts, but it may happen under time only because of the misplacement or geometry issues within the action (or too heavy hammers) All Renner parts there , where are the hammers from ?. I've find you can have some issues with jack's length or whippen height when using those parts (and the edge of the jack is variable, need to be examined for decision about polishing/rubbing) The backchecks look interesting , are they inserted slanted on those pianos ? Looking at the letoff button one may see something wrong with the regulation or absence of it . Hard to see if those are 16 mm or 17 mm shanks, also. The hanks may well be on the cushion only due to compression of the roller (if 16 mm exacerbated of course) Isaac -----Message d'origine----- De : Avery Todd [mailto:avery@ev1.net] Envoye : mercredi 1 septembre 2004 04:11 A : Pianotech Objet : Re: Big hammers I guess I'm showing my ignorance but what are you talking about?

As you can see, it has some obvious issues--like, when it was having trouble, nobody bothered to regulate it! :-) Well, I'm off to put some new casters on a church piano. Later!
