Christopher Brown RPT will be teaching at the National Convention in Lancaster PA. Please attend one or more of the 8 classes, which sequentially cover the Grandwork System of grand regulating. For demonstrating principles and protocols, Chris will employ a new Regulation Station, which will be on view at the Grandwork booth (#31).
The following lists the time, place, and general contents of each class:
1 Sell Your Grand Customers More Regulations - Wednesday (Period 1) in Heritage B
The Grandwork Regulation Protocol provides one-stop bench regulating for grand actions! Work done on the bench fits back in the piano and steps don’t undo previous steps. Good referencing prepares hammers to address their strings vertically, improving tone, power, and repetition. Consistent success with the Grandwork System brings confidence and enthusiasm that sell this work.
2 Short and Long Form Keyframe Bedding - Wednesday (Period 3) at Booth 31
Grand action regulating begins with keyframe bedding. Good tone, good power, and good repetition depend on it. Remove the return spring. Bed the cheekblocks. And test front and back rails. If they pass, WNG Keyframe Bedding Tool the balancerail. If they fail, the Grandwork Bedding Protocol guides you through what to do.
3 Bedding and Strike Sampling in the Piano - Wednesday (Period 4) at Booth 31
Learn a new, simpler, and more accurate approach to transferring grand bedding and strike information from piano to bench. Keys with Grandwork Keysteps memorize keyframe bedding. Hammers and the weight of a WNG Dip Tool memorize strike. And an additional mid-range Keystep maps the overall shape of the frontrail.
4 Bedding and Strike Setup on the Bench - Thursday (Period 1) at Booth 31
The Grandwork Custom Keybed provides all the features needed to recreate the piano’s keyframe bedding with stability. Elements fix position and support each rail to in-piano specs, including frontrail crowning. And the Grandwork Regulating Rack sets up a stable profile of strike that lowers to letoff, hammerline, and more.
5 Prep Parts to Vertical: Balance and Simplicity - Thursday (Period 2) at Booth 31
Fully regulate two samples on the bench, with a third to try new parts. File flared hammers with the Hammer Filing Jig. Travel shanks and square hammers to vertical at strike with the Squaring Platform, Shank Traveler, and Hammer Square. Discover how yes-no, go-nogo, and trial-and-error procedures produce superior results.
6 Hang Hammers Vertically at Strike - Thursday (Period 3) at Booth 31
The Grandwork Hammer Hanging Jig provides easy tail and shoulder positioning, with clearance for new shanks in the high treble. It coordinates with the Squaring Platform and Regulating Rack to hang hammers to be vertical at strike. Later, these hammers will accurately provide string leveling and mating in one step.
7 Fast and Precise Bench Regulating - Thursday (Period 4) at Booth 31
Square, space, and level keys in good light at a good height. Regulating Rack templates, fixed at strike, provide the perfect spacing scale to return to during regulating. Then, moving this strike profile to heights needed takes seconds. And steps proceed in an order that will not undo previous work.
8 Installation, String-to-Hammer Mating, and Voicing - Saturday (Period 4) in Heritage B
Back in the piano, after one trip to the bench, the regulation fits. Now, fine space hammers, settle wire, tune, and mate strings to their hammers. The strings will turn out parallel to the keybed, facilitating damper regulation and soft pedal voicing. And your vertical regulating will way simplify voicing.
