Grand Regulation Compromises

[Farrell]

Thanks Kjell.  10mm equals about 0.394 inches. Believe me, I agree that the
english system of measurements is quite a bit goofy. I was a scientist in a
previous life and fully appreciate the simplicity and utility of the metric
system. I also agree that regulation in the piano is best - but when you are
starting out with a train wreck that needs repairs, etc., I like to do it in
the shop.

Hi, Terry!

I have been waiting for someone to comment "bench-regualtion", but it seems
I have to do it ...;)

First of all: I prefer to regulate the grand-action in the piano. This is
the only way I feel I can do the best job. Two reasons for that: a) the
keyframe is (in some cases...)fitted to the keybed, and not to my
work-bench, and b) I can make decissions on how to regulate by making
samples, and then play the piano to see how it worked out.

If I have to do a "low-budget-job" (is this the case here?), I prefer to
make samples in all sections (filing test-hammers, then doing all regulating
and testing) before I take the action to my workshop and finish the work
there.

All these inch-measurements doesn`t tell me very much (I prefer mm !), but
as others have said, I would give key-dip a certain priority (max. 10 mm on
a small grand), and then make the compromises with blow-distance AND (if
nescessary) let-off, to get the aftertouch you want.

My motto: "The best action-work is done in bed"    (keybed  :-)

Just some thoughts from another Norwegian...

Thanks Phil, that's the way I am leaning. But not being a player, I don't
have a great feel for how much dip is too much dip. To the best of my
knowledge, 0.375" to 0.44" would be the normal range of dip, with most
pianos specking out around 0.4". Where do you draw the line on the high
side? If I set dip at 0.4", my blow distance will be 1-1/2". If I set dip at
0.44" or 0.45", I can accommodate a blow distance of 1-3/4". But isn't a dip
of 0.45" a bit much for most players? Does this depend on the size of piano?
Is it maybe that professional musicians that are capable of taking control
of the keyboard may like a deeper dip of say 0.43", but little Mrs.
Playlightly-and-not-too-good-at-that may prefer a more shallow dip???

I guess that is what my main question is, where do you draw the line on dip
in a case like this (spec at 3/8" - who knows why - little crummy piano - no
professional musician involved)? Thanks

Terry Farrell
