    Hello Jim, I regret not being able to contribute a little bit earlier but it's been (and still is a busy week). First, markup and Gross profit margin (GPM ) are 2 different things. They are different ways for determining the amount of gross profit ...

    Bill Instead of plugging the hole, have you thought about using CA glue? It has been found to be an excellent alternative to lose tuning pins. You don't even need to remove the pin, but I would recommend you put some newspaper between the pinblock ...

    Hello, I am trying to repair an oversized tuning pin hole in a Steinway grand. I have tried gluing wood veneer shims to the sides of the hole, to no avail. At present I have a 5/0 tuning pin in there that is not holding pitch. I think my best option ...

    Couple of considerations to add: 1. The return spring applies pressure, friction, and influence. It may not bear straight into the keyframe - check for indentations in the keyframe, check squareness to keybed. I take the spring out when regulating, ...

    Tim is right on the money. I was told years ago though that Bosendorfer recommends that the front casters be oriented pointing inwards, so that if there is going to be any flex in the bed, it would be to flex the middle upwards (theoretically always ...

    Wheels do not sit directly centered under the legs. Incorrect position of the wheels can cause the keybed to be torqued. People may scoff at this protocol, but I find it critical as a starting point: the wheels need to be set so they are facing either ...

    Joe, Actually no. Once the studs are set they're set. I "rarely" have trouble after that. Having said that, on a rare occasion I will notice the need to readjust one or two but it is ever so slight and quickly accomplished just on the offenders. ...

    Something is strange. Dip is certainly affected by changing the glide bolts. Steinway factory even refers to them as touch regulating bolts. But to keep changing after you alter the bolts' position, and that happens not through seasonal changes is ...

    Hi Keith, Sorry, I should have mentioned that I already checked the damper upstop rail - it is not too high, barely above the damper height when a sharp is depressed all the way down. Also, I can make the noise by quickly releasing the pedal completely ...

    Are all the stack screws absolutely tight? Does the stack sit squarely on the feet of the keyframe? Is the hammer rail straight when it's screwed down? I suggest that the stack is influencing the flexing of the keyframe so that when you put it in ...

    The upstop rail in the bass has more than a mm in clearance. LaRoy Edwards said if that happens the damper lever has too much room to accelerate at the end of the keystroke. It gets "flung" and rebounds off the upstop rail instead of dropping slowly ...

    Yamaha keeps track of their parts by part number. If the GP1 and the GH1 use the same size hammer shank, then they would have the same part number, which means that they would both be on back order. If you can't wait, then you would need to get them from ...

    Peter On a 25 year old piano, the bass dampers will have gotten pretty hard. Try voicing them first, by literally using your voicing tool to fluff up the felts. If that doesn't work, yes, replace the damper felts. Wi

    Hello all, I tune a 1998 Yamaha C2 for our music festival that has a noticeable thumping sound as the bass dampers hit the strings. It is not coming from the trapwork - if I hold down the keys on the bottom half of the piano, lifting the bass and treble ...

    For both "fine" and "coarse" it is possible to set the spinner speed. Try various settings - I leave "smoothing" on for both. The only needle/stability control is the smoothing on or off, so it is pretty limited amount of control. The frame rate ...

    By adding mass to the hammers and leads to the keys to compensate BW increasing you will increase dynamic resistance of the action which will make pianist feel the action even heavier. Alexander Brusilovsky
