This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I noticed that a checking of the centers heights and position on many action stacks, but particularly Steinway, will show that there are disprcrepancies. Correcting them with little papering , made in the cross direction of the usual one, allow for a smoothing of these, I felt it immediately and it can be measured in the DW UW relationship also. Gluing himself the new rollers when changing shanks (with they shanks yet on the rail and the centers checked) seem to take care of a lot of these differences. Rollers may be aligned with a rule - gluing time 30 min approx.. I've heard of some using a gig for that job, a picture would be appreciated . Thanks Best regards.

Snook Envoyé : mercredi 14 mai 2003 07:28 À : Pianotech Objet : Action Geometry Consistency When I do concert level regulation, I try and get key dip, aftertouch, letoff, and blow distance as even as possible (in that order). As a general rule, I try to maintain evenness in aftertouch and key dip, which forces me to distribute the majority of the inaccuracies between the blow distance and the letoff. Every once in a while I come across a note where something in the action geometry is obviously wrong (e.g. to get everything else correct, the blow distance would need to be in excess of 1/8" higher/lower than the rest of the hammer line). What do I do to fix this problem? Bradley M.
