Re: Life inside a guitar case... |
Dear friends;
Thank you for the replies. It was excactly what I was looking for: The
physists explanation, - not the everyday assumptions of some music
department salesman, or some nerd-like musician like myself.
The egg-story is interesting, though the succés-criteria of the egg is quite
simple to tell: Even it breaks or it doesn't..
Another story is maybe the state of a $ 15.000 classical guitar when dropped
once,
twice or 10 times from 1 or 2 meters by airline staff. It may not brake, but
could get unvisible, but hearable damages. Wood is alive. The instruments
improves over the years when played regularly. In the same way could it lose
quality when dropped.
I presently have a "Liteflite" hard case made by Hiscox in England.
The guitar is fixed inside the case. The plasticlike material on the outside
is
probably 5 milimeters thick and the layer inside about 1cm. I think there
must also be a 1-2 cm layer of flamingo between the plastic outside and the
teddy layer inside. I now found this link about it.
http://www.hiscoxcases.com/construct.htm
I wonder what would happen to the guitar if it was dropped from 1-2 meters
protected by this case, which I believe is not the same as having a 90 kg
(180 pounds) man sitting on it. It may be a lot worse.
Some professional guitarists refuse to hand over the instruments to the
airlines, but insist on carrying it with them in the
cabin. This is much harder nowadays after 9.11.2001, and more so with the
new wealth of discount airlines who must be stricter about everything in
order to cut prices.
Others, who travel very much with the guitar have enormous flight cases
which seem to combine stiffness with very thick inside blow absorber. I
think they must be extremely heavy though.
The great Spanish guitarist Andrés Segovia always bought 2 seats: one for
himself and another for the guitar. But I think he could afford it.

To borrow a concept from automotive safety engineering, there are two
collisiions to worry about: the case with the ground and the guitar
with the case.
High speed racing automobiles are designed to be frangible - in an
impact they practically disintegrate while absorbing all the energy of
a high-speed collision as deformation of expendable body parts. The
driver is restrained within a rigid cage that the rest of the car is
literally built around. This allows the driver to literally walk away
from a crash at over 250 kph.
Extending this idea to your guitar case, I would suggest using a
slightly oversized case and wrapping the instrument in a layer of
padding something like bubble wrap. At an absolute minimum you would
want to enclose the head and to pad the heel, shoulders, hips, tail,
and bridge.
If you wish to protect your guitar from direct contact with the plastic
of the padding you could fashion a drawstring sack out of fabric.
If you are able and willing you could also include sensors to indicate
if the package has been shocked in handling. Google "shock sensor" and
'packaging'
Always insure it.

If you can afford this instrument you can afford to buy it its own
seat on the plane.
Or take the bus.

Ehh... $ 15.000 is the price of a cheap car. So according to you, everybody
who can afford a cheap car, can also afford to buy 2 seats everytime they
fly.
