For three centuries, we have suffered the choice between working on grand actions in the piano (with issues of inaccessibility, poor light, and tough ergonomics) or doing this work on a bench (where the keyframe sits differently and our measuring has accumulated error). The traditional hybrid solution sends us in circles, working and reworking, until the best that can be done is accomplished. With much experience, fewer circles produce better results.
Grandwork™ tools and protocols solve, simplify, and enhance. These tools and protocols offer consistently successful outcomes. Grand regulating can now be a linear process with a predictable beginning, middle, and end. And the middle portion, from key leveling to aftertouch, can be performed out on a bench and result in work that fits back in the piano!
The tools offered on this website methodically prepare a grand action for string-to-hammer mating and the voicing that depends on it. The following tools have been designed and manufactured by Christopher Brown, RPT:
Check out our Regulation Station packages, but if they are too expensive for now, a Regulating Rack or a Keystep Bedding Kit or even a Set of Gauge Keys can make a difference.

Q. Thoughts on aftertouch affecting checking? A. Aftertouch directly affects backchecking. If we define aftertouch as key travel after letoff, this can translate to backcheck travel after letoff, since the backcheck is attached to the key. Further key stroke equals greater backcheck reach and less equals less. Imagine no aftertouch. The jack just clears the knuckle. As the hammer sets strings in motion and starts to bounce away, the backcheck is waiting below, stopped with the rest of the key at full dip. But think where it can be. In order to clear the tail on the way up, the backcheck can only be set so far forward and that position is the same regardless of blow distance, dip, or...
