Michael, now that I've answered all your questions, are bonus points, a
cookie,
or other perks applicable? You've obviously given a lot of thought to the
questions. No offense, but you must not have given as much thought to the
answers. They're so easy, I felt like I was cheating while responding. Even
with no cookie, this was much more fun than 200 people guessing what one
person
did to find or correct a problem. In spite of bandwith that will swamp servers
for months, thanks for thinking up all this neat stuff! Next round, maybe one
or two questions at a time...? Here are my thoughts:

Q: Why do they design pianos which are hard to figure out how to get 
open, humiliating even the most experienced techs? 
A: Haven't thought of Alton Suggs in years. Factory workers (particularly
finish repair) also complained about this, and Alton wasn't with Kranich &
Bach
too long afterwards. He also installed pinblocks for Chickering for a while,
and later worked at Gulbransen and Winter. By then, his reputation had spread,
and no one in the piano industry would hire him. The last I heard, Mr. Suggs
had passed away, but his grandson was working for Ford, installing transverse
mounted engines in such a manner that it was necessary to remove the engine to
install a spark plug on the firewall side.

Q: What's the real reason they invented the sostinuto? 
A: If the sostinuto is in the same family as the sostenuto, the reason for
development was to provide the ability to play the twenty-seven pieces of
music
that were written and notated specifically for the device.

Q: Why are lid props placed so you can't put even the shortest tuning 
lever on the top pins parallel to the string? 
A1: On toy pianos, when the rim starts to curve immediately at the capo
bar, it
becomes a logistics nightmare to find a place to install the prop stick.
Considering the size and weight of the little topboards, sometimes its faster
to remove both the lid and the lid prop.
A2: In earlier times, left-handed tuners were far more common than today.

Q: Why are console lids designed to go "Bang" when you close them so 
the customer thinks you hit their piano with a sledge? 
A: This wasn't an intentional design characteristic, rather a by-product of
installing a 100 pound topboard on a 300 pound piano. That's the nature of 
beaverboard, and that's the way Kimball decided to do it. The special Harley
Davidson tool mentioned is also useful for correcting lost motion on that same
model, after the action is removed for work that had nothing to do with lost
motion.

Q: Why do they always play around with the specs on action replacement 
parts just enough to fool the tech into still using them, yet just 
enough to cause all kinds of problems? (that must have taken some 
careful study!) 
A: Excellent question, but more appropriate for Economics 101. Say that
original parts work flawlessly for 20 years or more. This does not provide
sufficient incentive or cash flow to keep designers, draftsmen, labor, and
other support operations busy. Instead of cutbacks and layoffs, another viable
option is to simply make parts with problems already built-in, sell those,
then
sell improved versions with the inherent problems retro-designed. This
phenomenon is not exclusive to the piano industry, therefore our little corner
can only accept minor responsibility.

Q: Why do they design fall boards to catch pencils and shoot them 
right into the capstans where they can do the most harm? 
A: Without this important safety net, there are no other conditions that
qualify as an emergency condition on a piano. The possible exception to this
would be captive cat removal, but even this permits a casual hamburger and
shake on the way to the call. Otherwise, we would have to create other reasons
to charge for basic service calls.

Q: Why do they have sixteen screws to remove an action with the two 
fall board ones too close to the the case with end blocks carefully 
designed to bounce these microscopic screws on the floor to hide in the 
shag rug or down the crack along the key? 
A: I may have misunderstood this question. Fallboard screws, once found (see
thread on brass magnet), can be tossed. They are a shipping expedient, after
which (a) their service is no longer required (b) with or without, no piano
mover trusts the screws. (See 'Extra stuff during removal') 

Q: Why do replacement hammer shanks have extra long drop screws to hit 
the pinblock and give you three choices--cut em off, plane down the 
pinblock or lower the drop one inch? 
A1: These post-production assemblies are provided with many more options than
the originals. They fit nicely in glue sandwiches; i.e., pinplank stock
that is
=thinner= than the original block, and with a little luck, the screws do very
little damage to the stretcher.
A2: The additional one inch of drop provides an additional element of control
in the field, especially on pianos with severe gospel damage. The drop being
lower permits an even lower let-off.
A3: I prefer too long to too short -- I submit that silver-soldering tiny
extensions on 88 little screws would be far too labor intensive.

Q: Why do they put any locks on pianos? 
A: This feature was implemented due to the lobbying efforts of finish repair
professionals. By installing a lock that is just slightly harder to defeat
than
no lock at all, the resulting damage to the lock assembly, the hinges, the
stretcher, and sometimes the lock bar provide additional income opportunities
for those who have contracts with junior high schools.

Q: Why do console/studio fallboards have to make it impossible to 
regulate capstans without removal and then be a mental test on how to 
put them back? (afew you can tip up, but watch out they're designed to 
fall and kill your wrists) 
A: I agree that all verticals should have a service door. Meanwhile, it's
easier to remove the fallboard. I'm still waiting for a gas-filled, slow
release shock absorber on console fallboards. I guess no hatch-back car maker
has needed one quite this short.

Q: Why do they design lids and capo bars to force us to use longer 
tuning hammer tips and get poorer results? 
A: One thing led to another in initial design; the opposite condition of
cutting the same board too short two times in succession; some of these pianos
are actually improved when tuned with a modified floor shift from a Kenworth.
(If answer wrong for question, see next)

Q: Why don't they use the right amount of counterbearing so the piano 
can be easily tuned and stable? 
A: 18~22 degrees; pick one or invent another; diminishing returns on either
side of this window. Other than that, Mason & Hamlin, Knabe and certain others
require alternate methods to assure stability. (Also see Harley tool above)

Q: Why design an action so you can't get a wippen out without removing 
all kinds of stuff? 
A1: For verticals, there was at least one piano that the front rolled away
from
the back on built-in steel ramps, but they're not that common in many areas.
Careful with that 'other' stuff. I discovered that some of it may be useful
later on. The rest can be cleverly hidden in nooks and crannies of your
service
vehicle.
A2: For grands, the entire process goes much faster when movers use the right
screws in the lyre, or when a previous technician resists using plate lags
through the lyre into the keyframe. An air impact driver is yet another
expedient, but not everyone has space to carry the compressor.

Q: Why do they design music racks held together with microscopic screws 
which can't carry any load and cannot be "redesigned"? 
A: More is better; it's hard to install #10 or #12 screws into the edge of a
board that's only 1/4" thick without creating additional damage. Two 2x12's
edge-joined/doweled work pretty good for large format orchestra scores, but
some folks can still find heavier music and defeat the best of designs.

Q: Why do they design the tenor strings to have such low tension they 
go wild one month into a weather change? (Who cares about an even tenor 
break if the thing is going to have bar room octaves that fast!) 
A1: Those offerings were not intended for bar rooms, or pianists. They were
originally meant to hold freshwater aquariums closer to eye level, and
never be
opened. The recent thread on having a 'flag' on the becket is further
testimonial that these pianos were just to fill empty spaces in rooms. An
additional clue were tuning pins that were too close to each other or to a
plate strut to accommodate a tuning lever. The pricing structure no doubt
caused their overwhelming popularity in many homes... and nightclubs. 
A2: In at least a few instances, rescaling was done on extant backs to
minimize
the effects of the crossover area. Cost to change was a matter of substituting
a few strings, and possibly the hammer strike point in the affected area.
Upper
management denied permission. (See -anything- authored by Del Fandrich,
[although he's not my reference on this]).

Q: Why use those buzzy continuous hinges anywhere on a piano? 
A: Cosmetics - the Stanley garage door hinges didn't look as good, required
too
much space, and rattled worse. (Note: there are three fixes for this, none of
them involve the use of  felt).

Q: Why don't they support a grand music desk somewhere along its 
length instead of just the two ends using only a quarter inch of wood? 
A1: This has been tried, most recently in one Baldwin model, by screwing the
desk into a plate strut. Early evidence indicates that ambitious seventh
graders can defeat (destroy) this as easily as a lock assembly.
A2: Bonus answer. I originally read the question as music -rack- support. The
center-mount, quadruple fold, easily bent, single-position and incorrectly
angled style requires post-graduate work to learn how to install. The
multi-adjustable, easily broken end mount demands no extra training.

Q: Why would anyone design a lid so to be opened the piano has to come 
away from the wall? 
A1: Obviously a trick question -- vertical pianos are not supposed to be flush
to the wall.
A2: This design serves as a gentle reminder. We're supposed to periodically
check the back of the piano, especially the lower liner area, for plaster
coated nails, marbles, rubber balls (minus the paddle they became detached
from), costume jewelry, or exactly two pennies. For other discoveries, latex
gloves are highly recommended.

Q: All pianos should have toe blocks! 
A: We're no longer in a war-time environment. Alternative methods have to be
created to control male population levels. It is unfortunate that curious
six-year old males were selected as token offerings, but that becomes a
parental control problem, and need not be addressed by the manufacturer.
Therefore, sales of Euro-styled pianos continues to grow.

Q: Why can't the Japanesse and Americans all use the same wire size 
number for the same size string? 
A: Another trick question. Many Americans are still waiting for the signal to
convert to metric. Still others saw the value and didn't wait to pass 'go'.
When this happens, the wire will have corresponding number to gauge
references.
What -did- ever happen to that initiative?

Q: Why do the Russians reverse the order of the tuning pins in the 
bass so the tuner gets confused about which pin to be on and breaks a 
string? 
A: Sigh. Refer to previous answers; i.e., if they put the tuning pins beneath
the bridge and installed remote-control power steering to turn them -- it
wouldn't make the resulting product any better.

Q: Why do they design trapwork to rub on each other? 
A: So Susan Kline has something to write about.

Q: Why do they design it so the pedal rods have to fall out of place 
when the action is removed? 
A1: So Susan Graham had something to write about.
A2: If anyone has failed to experience any pedal rods that =don't= fall out of
place -- things get real busy, real fast, and the situation has the potential
to turn ugly.

Q: Why do they design pedal lyres to come apart? 
A: A coincidental side effect to efficient manufacturing. Analogy: it's
okay to
hollow out a tree to build a canoe, but it's just bad use of resources to use
an entire tree to carve out one toothpick.

Q: Why do they design the braces to fall out? 
A: This feature encourages technicians to practice iso-kinetic exercises, use
of certain Yoga positions, and assume all sorts of other healthful positions.
It's also a good excuse for a quick nap while maintaining a work 'attitude'.
The downside is that it also encourages many technicians to use vocabulary
they
haven't used since the Navy.

Q: Why did they ever have to invent the una-chorda pedal? can't 
pianists learn to play soft without it? doesn't it add an awful lot of 
cost with very little gain? 
A1: A three-parter? The unacorda helped restore 'piano' after 'forte' was
introduced;
A2: Many professionals either abstain during formative years, or, are
currently
trying to quit;
A3: Not allowing for pedals, the unacorda costs far less than Orville's
popcorn, which, if TV marketing were eliminated, could be sold for around ten
dollars per silo. The action must be accessible for pencil removal, without
additional need for plate, belly rail, soundboard, or keybed removal -- so why
not make it 'fluid' at the same time.

Q: Then there's those fake pedals, connected to the same trap lever! 
A: Those pedal assemblies came already configured as a set of three from
Ramsey
& Co. Again, it's a matter of choices. (a) have one pedal flopping around, (b)
adding one additional prop bolt and nut; (c) taking time to change excuses
into
into a 'sales feature'. Item B was was finally agreed upon, following a close
contest with item C.

Q: Why do they design wood dowel letoff buttons coupled with extra 
long jack regulating screws? 
A1: Failure to compare sufficient samples to original drawings;
A2: Some tools are too big to fit between dowels to reach jack screws --
requires either Yamaha or Mehaffey drop regulator as work-around. 
A3: Care must be taken to assure that long screws are not jack stop rail
adjustments.

Q: Boy am I glad it's Friday!
A: Me too. You obviously had quite a busy week!
