Introduc on Make Certain that the Kit will Fit! All kits play 80 notes, excluding the first and last 4 keys of the standard piano keyboard. The following ques ons should be asked before beginning an installa on: 1. Is it a grand or upright piano? The kit will not fit into a spinet piano. 2. Is the keybed made of wood or a wood‐veneered laminate? 3. Does the piano have a range of 88 notes, extending from low A to high C? 4. Is the keyframe made of wood? 5. Is the piano well‐regulated and in good mechanical condi on?. ...
Introduc on Piano Ac on Regula on This discussion is not intended to be a complete course on grand ac on regula on, but rather may prove helpful in restoring the ac on to proper performance. Proper alignment of ac on parts, and key easing are all very important steps in the regula on procedure. The following procedure assumes that this preliminary work has been checked and performed as necessary. Before removing the ac on from the ac on cavity, evaluate ac on regula on. If the ac on is not well regulated, proper perfor‐ mance of the system cannot be expected. During the installa on process of the PNOma on II Player System, it is quite possible that ac on regula on will be directly affected. A por on of the keyframe and back rail cloth will be removed so that the note solenoid plungers can contact the keytails. This opera on may cause the keytails to be lower than their original posi on. The result of lower key tails is an increase in both key height, and hammer strike distance. Restoring the strike distance to specifica ons by turning out the capstan screws is not the proper remedy. Always re‐work the back rail height so that the key height is at its original posi on. ‐ Are the keys level? ‐ Do the hammers let off 1/8 in the bass, tapering to 1/16 in the high treble? ‐ Is the drop 1/16 below the point of let‐off? ‐ Is the hammer line straight? ‐ Are the hammer shanks approximately one shank thickness above the hammer rest rail? ‐ Is there adequate a er‐touch? ...
Installa on Procedure Upright Piano Installa on ‐ Recommenda ons... This sec on outlines the differences between the installa on of the QRS kit in an upright piano versus a grand. The differences are rela vely small, and an installer familiar with the installa on procedure for a grand piano should have no difficulty installing the system in an upright. The differences are as follows: On a grand piano the slot cut into the keybed is determined by the loca on of the keytails. The posi on of the ac on determines where to cut the slot and you mount the rail to the bo om of the keybed accordingly. On an upright piano, with limited space for the components, the slot loca on is determined the posi on of the key solenoid rail assembly. Begin by determining how close can you mount the rail to the plate and s ll have the plungers strike the bo om of the ...

Installa on Procedure Key Solenoid Rail Assembly ‐ Solenoid to Key Alignment With the piano ac on on your workbench and the fronts of the keys facing away from you. Place the solenoid rail on the workbench in front of the keytails and put the plungers inside the solenoids. Turn the solenoid rail assembly on its side, so that the plungers are now parallel to the workbench surface and the felt plunger ps are touching the back ends of the piano keys. The first plunger should start all the way to the le side of the rail. Secure the rail and ac on with the two clamps so they will not move during the alignment process. Mark which side is bass and treble. Make sure all the solenoid plates are free moving. If they are not, use an 11/32” nut driver to loosen them. The spacing between sec ons has been held in check by the introduc on of solenoid assembly pairs adjacent to the breaks. Because not all sec ons on a piano will have an even number of notes played in them, those which have an odd number will require a modified solenoid assembly to provide the addi onal note required, and this modified note will be placed adjacent to a sec on break or at either end. Count the number of keys to be played in each sec on. If there is an even number, align the solenoids with plungers already on the rail with the centers of their respec ve key tails. If the number of keys to be played is odd, simply re‐ move one of the solenoids from the double moun ng bracket and con nue to the alignment of the next sec on. If necessary, cut away the unused por on of the rail ends with a hack saw and file off all burrs with a metal file. Be careful not to cut away the rail bracket moun ng holes, or cut any solenoid wires. Mount all 8 rail support brackets to the rail with the 10‐32 X 7/16" screws and #10 external star washers. Note: The distance from the bo om of the keybed to the bo om of the keytail felt should be equal to the distance from the top of the solenoid plunger to the top of the rail moun ng brackets. ...

Installa on Procedure Modifying the Keyframe ‐ Grand... If you are installing a QRS PNOscan III record system you should incorporate it’s installa on while modifying the pi‐ ano ac on. The PNOscan III has it’s own installa on manual. The Keyframe will probably require modifica on to accommodate the Key Solenoid Rail Assembly. The key tails must protrude over the back of the ac on frame, so the rear of the key frame must be cut away. Tools needed for this chapter: pencil, paper, wood chisel, straightedge, jig saw, palm sander & sand paper, u lity knife, wood glue and an assortment of screwdrivers. At this point in the installa on, the piano is on its legs, the fall board, keyslip, and cheek blocks have been removed, and the lyre is s ll in place. The piano has been measured to verify that the Note Rail Assembly will fit. Measure the distance the ac on shi s when the le (una corda) pedal is pressed. (If a hammer li rail is installed, measure the distance the hammers li for a given movement of the so pedal lyre li rod.) Measure the distance the ...

Installa on Procedure ...Modifying the Keyframe ‐ Grand... The key frame must now be cut. Remove all keys. With a jig saw, follow the pencil line and cut away the frame in each sec on between the breaks. With the palm sander, clean up all the rough edges. The ac on is now ready to be used to locate the posi ons of the slots through the piano's keybed. Place the keyframe into the grand piano case and secure it with the right and le cheek blocks. With a short, sharp pencil, reach into the keyboard compartment and mark the notched rear most limits of the keyframe, including the right and le extremes of each notch. These lines will be used to iden fy the exact loca ons of the keybed slots on the underside of the keybed, so be certain to make well‐defined pencil lines. Remove the keyframe and reglue the keytail felt flush with the back of the keyframe. Measuring the key dip before and a er reposi oning the felt is recommended. If it is the same, less regula on will be required. If it has changed, ...

Installa on Procedure Cu ng the Keybed Slot... Tools needed for this chapter include a circular saw (sabre saw with a sufficiently long blade/ router may be used), a power drill with a sharp 1‐3/4" Forstner bit (or wood boring bit), various screwdrivers, a frame square, a pencil, a tape measure, and paint that matches the underside of the piano. At this point the piano is on its legs, the ac on is outside of the piano case and has been modified to allow the key tails to protrude over the rear of the key frame by 1‐1/4". Felts are a ached to the undersides of each key tail, and the original trapwork is s ll in place. Next, have an assistant press the sustain pedal. While he depresses it, measure the distance the pedal lyre li rod moves and write it down. Likewise, measure the distance the damper li rail rises when the pedal is pressed. This measurement can be taken from inside the case. Next, mark the exact loca on of the upward extension of the pedal ...

Installa on Procedure ...Cu ng the Keybed Slot Taking into account any varia ons in the contour of the front of the piano and using the frame square aligned with the mark just made on the front underside of the keybed, measure and mark the depth measurement on the underside of the keybed. Next, measure 1/4" toward the front of the piano scribing a straight line between the bass and treble notes. Then measure 1‐3/4" toward the rear of the piano from the newly scribed line. Whenever possible we recom‐ mend keeping in the breaks. Each slot should be at least 1‐3/4" wide (2” Maximum). The longitudinal center of each slot must correspond to the center line of the felt padded key tails, which is 1/2" in from the end of each key. Verify the marks just made. Drill a small exploratory hole within each slot and compare the posi on of the slot with the marks made inside the case. Correct each slot posi on as required. Using a 1‐3/4" Forstner bit, drill holes centered at the ends of each slot. ...
Installa on Procedure Installing the So ‐Shi Lever The So Shi (una corda) pedal mechanism usually includes a long, cast‐iron bell crank lever whose short arm pro‐ trudes though the keybed to engage a groove cut in the bo om of the keyframe somewhere beneath the treble sec‐ on. The shi pedal in this configura on does not have to pass through the solenoid rail and, therefore, may o en be le untouched. However, on some pianos you may have to move the so shi toward the front of the piano to accom‐ modate for the width of the rail. For the pianos that need modifica on, brackets have been included in the kit for easy readjustment. It is a good idea to leave one of the original wooden blocks a aching the so shi lever to the key bed, and only use one of the brackets supplied. This will make adjus ng the So Shi lever much easier. The brack‐ ets can be a ached to the keybed with four #10 x 1” moun ng screws. The pedal must shi the ac on the same dis‐ tance as before with the same pedal movement. Refer to the measurements taken when the trapwork was removed to verify that this behavior has been retained (See “Modify the Piano Ac on” sec on). Measuring from the front edge of the slot there should be 2‐1/4 inches to the front edge of the so ‐shi hole. Slot 2-1/4”...

Installa on Procedure ...Installing the Sustain Pedal Solenoid ‐ Grand... You can now turn your a en on to the installa on of the sustain pedal solenoid assembly. This procedure is not required when sustain pedal is not installed. Because there is a certain amount of varia on in the architecture of grand pianos, you will probably have to custom‐tailor the following direc ons to suit the mechanical dimensions of the par cular instrument you are working on. The key elements to focus on here include the sustain pedal lyre rod's upward projec on onto the keybed immediately above it, the loca on of the large hole through which the original sustain pedal pitman dowel projected to reach its corresponding hole in the wooden or aluminum damper tray (which li s all of the piano's dampers simultaneously), and the rearmost OUTSIDE ver cal wall of the keyboard compartment, called "the belly rail." The proper installa on of the sustain pedal solenoid assembly takes into account the dimensional rela onships of these three elements. In addi on to providing for both the manual and automa c opera on of the piano's dampers, you want to give the sustain pedal solenoid as much mechanical advantage as possible in order to minimize the power required to ac vate it. Despite the excellent design of the sustain pedal solenoid assembly, its long term opera on depends upon your skill in loca ng the various leverage‐points which enable it to func on both manually and auto‐ ma cally. Op mally, the sustain pedal solenoid assembly will be mounted on the belly‐rail immediately behind the sustain pitman dowel which formerly con‐ nected the old trapwork lever's far end to the damper tray in the keyboard compartment. This arrangement provides the shortest distance between ...

Installa on Procedure Install the Universal Sostenuto Assembly... Not used Iden fy the piano’s Sostenuto type. Push ‐ The Sostenuto is engaged when the actuator rises toward the strings. Pull ‐ The Sostenuto is engaged when the actuator descends away from the strings. Steinway ‐ Part of the assembly is built into the ac on. You will need to order the Steinway Sostenuto Assembly from QRS. Part # 70897 These instruc ons explain a Pull Type Sostenuto installa on. Remove the exis ng actuator a ached to the Sostenuto blade. Drill a hole in the new actuator for the staple. Clamp to the Sostenuto rod here. Use one of these three holes for the “L” shaped thread-rod.
Installa on Procedure ...Installing the Universal Sostenuto Assembly... Install the push lever which consists of the Push Block, the Main Sha , the Sha Bearings and the Swing Arm. Determine placement of the push lever by first installing the pedal lyre on the piano. Place the push lever so that the end of the lyre’s Sostenuto rod is on the outer edge of the push block when the pedal is not depressed. Make sure that there is clearance as the push block travels through its arc as the pedal is depressed. The push block posi‐ on is adjustable by loosening the set‐screw. There are several indents in the sha for posi oning. Also note the posi on of the sha bearing and bushing has been placed as close to the bend in the sha as possible to prevent the bushing from working its way out during opera on. Only this sha bearing should be fastened in place at this me. It is OK for the sha bearings to slightly overhang the slot. The assembly may need inset into the keybed to accommodate the key solenoid rail and rail cover. “L” Shaped Thread-Rod Shaft Bushing Main Shaft Swing Arm Shaft Bearings Push Block & Felt Pad Insert the second Sha Bearing and the Swing Arm to the Main Sha .
