Piano Tuners Grand Piano String Height Gauge and Regulating Jig
Here is the easy answer to grand piano regulation! Two simple devices together make the job much easier. 1 - A string-height gauge that only requires putting the gauge through between the strings to the key bed, sliding the t-bar to the underside of the strings and reading off the measurement (in millimeters) of the keybed-to-string height.

2 - A 2-piece jig which affixes to the grand action standards , providing a'virtual string' used to set string height to the outside two trial hammers of each section, taking the measurement from the vernier to set the blow distance and the regulation for that section, then repeated for other sections of the piano. Picture descriptions show; though I've put the described depth jig (4) and reg jig (12) in positions 1+2 now. Removal of the key blocks. Removing the action (be careful not to to touch any key when withdrawing the action to prevent snapping off hammer heads). Inserting the height gauge between strings at the start of a section (you will need to do two measurements per section - first and last note of each).

Frame position relative to a string may dictate using the second note in from the end of a section. Sliding the t-bar up the post to sit under the string. This shows the correct position of the stop under the strings ensure the post is vertical and on the key bed, not the lower gaps in between, which some pianos have. Close up of the gauge showing the vernier scale (measurements between 150-230mm). Loosening an action standard screw of one section..

And the next of the same section. This is so you can trap the foot of the jig under the SCREW (not the standard) to hold the arm in place. Tightening the screw to hold the foot.

Placing the'virtual string' between the two arms. Using the gauge to set the underside of the'virtual string' to the piano's string height. View of the jig in place on an action showing the'virtual string' over the hammers. If you're using this jig on a Steinway then you have to mount the feet on a wooden block as the action standards won't permit the foot to be trapped under the securing screw. It's perhaps more practical to mount the jig on a sturdy wood block the width of a section of hammers anyway.. (make it suitable for the widest section) otherwise it's difficult to transfer the string height measurement when the jig is on the standards as the action gets in the way of planting the gauge on the base surface.

Once you've done this, set the trial hammers (first and last in the section you're working on) then with those at the correct height relative to the string, mount the jig on the action standards and set the rest of the hammers level to the first/last for an even line in the section. Repeat for the other sections. Now you're ready to regulate the action clear of the piano using the freedom of the bench (or top of the piano) rather than in/under the restricted inside of the instrument.

Final setting up can be done in the piano but this makes the general regulating so much easier. Gauge made from stainless steel by a local engineering firm in Sheffield (UK) where tuning forks are also made. Jig design probably originated at LCF but this is hand made by me in aluminium from a drawing.
