Thanks for the response.  I have looked at the relationship of the keys =
to the key slip and there was only about 5 mm clearance between the keys =
and the key slip when depressed even on the keys with the least dip =
which was 3/8.  The depressed keys are even cIoser to the key slip on =
the ends of the keyboard, due to the crowned Steinway key leveling.=20

    Thanks, Bob. Looking at where the keys end up at full dip is one of =
the things I was talking about when I said to check out the action with =
the hardware in place. Sounds like the keys may be getting a bit too =
close to the keyslip, and since you were concerned about not enough dip, =
this may mean that the keys are lower than they should be to start out.

 I do need to look at the fallboard/key relationship. It's doesn't seem =
to hit the key tops when closed.  As long as closed fallboard isn't =
touching key tops then key ht. is not too high, correct?  But how can =
you see how much higher they could have been once the fall board is =
closed?=20

    That's not exactly what I was thinking of. You don't have to worry =
about the fallboard hitting the keys when you close it, unless perhaps =
the fallboard is closing too far due to missing rubber button thingees, =
or something. With the fallboard up, look at the space between the top =
of the key and the fallboard. If there's a big gap there, it's a sure =
sign that your keys are too low and will probably need to be re-leveled. =
It's a bit harder on a Steinway with those dowels under the keys, but =
nothing to worry about.  I find, actually, that the Steinway specs on =
key height usually will work just fine, but you do want to check before =
you change it, to make sure you have clearance. I think I've seen maybe =
two where the specs wouldn't have been right.



     There does seem to be an abundant amount of balance rail key pin =
sticking up above the button but not hardly different from another M of =
same vintage with which I've done some comparison.=20

    I would think that that's another possible indication that the keys =
are low.  Conversely, if you put punchings in there to raise the keys, =
make sure that there is still enough balance rail pin showing above the =
bushing to hold it securely. Shouldn't be a problem.

I am working currently only with sample white and black keys in each =
section rather than trying to do all of anything and finding it to be =
incorrect. I know that specs are only guidelines and that individual =
pianos require individual specs.  But, aren't there some extremes in =
adjustment of things such as blow distance and dip that say - "there is =
another problem which you've not corrected" or, "this is extreme but =
necessary for this piano." ?=20

Bob

    I think that when you start to get things going on the regulation, =
that everything will start to work out, and that there won't end up =
being any extremes here.  I would start at the beginning and just do a =
sample regulation on a few notes and I think you'll see that it will =
come together for you.=20
