[pianotech] was curve now glide

[Piano Boutique]

What about Yamaha that levels one octave at a time.  If played in the center the most, they would have a valley in no time at all.

  Dittos on this practice David.  That's one of the methods I was taught, as well, and the one I stick with when possible.  I think if nothing else is clear, we have resolved that what "Steinway" does seems to be somewhat ephemeral in nature.

    Not to be a contrarian but I bed keyframes with everything together.  The technique I use was presented by Steinway’s John Patton at one of the conventions.   Can be done in a couple of minutes or less on a Steinway.  Pianos that have glides that are buried underneath the keys require at least the removal of the covering keys naturally.  The process is simple and requires you to just back off the glides enough to be sure that none are touching the keybed which you can test be pressing down on the glide bolt with a wrench (or a screw driver if it’s a screw type) using the back of your hand against the pinblock as leverage.  You will be able to see the keys flex downward when there is a space there.  When they all produce a bit of flex then start in the center and turn each bolt down until there is no flex, backing it off just slightly in order to produce that telltale knock and then just setting the bolt down to eliminate the knock/flex.  Go alternately outward until all are bedded.  Then go back to the center and make sure you haven’t “unbedded” the center glides by turning the outer bolts down too far.  If you have then start over.  It requires a bit of touch and sensitivity but it can be done quickly and accurately with some practice.
