TESTER CAN BE USED FOR EVERY REED:
first implement to determine the hardness of your canes. All
criterions you know so far (fingernail-test, twist-test. Colour,
etc.) are irrelevant. At best you can use these criterions to chose
the cane tubes.
building your reeds you should grade the canes by hardness. The
probability to get fine reeds from a sort of one hardness is much
bigger than otherwise. Especially for beginners this tester
absolutely necessary. Even en experienced reed-builder might be
astonished how often he has failed before. The different hardness is
also the explanation why each of ten reeds has another quality.
to latest relations does one definite hardness belong to each blower.
When you work with precision and care under keeping your measures
your reed manufacturing will produce a very high rate oafs called
measure inside planet canes dryly. (Because of the little thickness
oboe canes can be measured after splitting) It takes you only some
minutes to operate this implement.
musicians save a lot of time because they have to build less than
halfround ball is pressed into the cane with constant pressure that
can't be influenced. The softer the wood is the ball enters the cane.
The scale indicates the ball's way in 1/100mm. Besides the hardness
tester the implement has a measuring instrument to find out the
0 - 2,5 mm reading 1/100 mm
reset the scale to 0
the lever on the right side down

micrometer now indicates the thickness in 1/100 mm
the cane under the feeler on the right
down your left hand next to the instrument on the table
with your forefinger the lever slowly and carefully till the cane
is touched. You feel it like the trigger on a gun.
in this position and reset the scale to 0
press the lever totally down. The wood gives way about 10 seconds.
micrometer indicates the way the ball enters in 1/100 mm.
wood has about 10/100 mm,
about 20/100 mm
entering way corresponds to hardness 14.
will notice astonishedly that most canes thought to be hard turn out
to be soft. Other grades aren't worse. Either you use other measures
or you leave them to a colleque.
AT THE BEGINNING
any 20 planes inside
and notice the hardness
the reeds and try them
look at the hardness and memory
to experiences pupils and students use a hardness of 14 - 19,
professional musicians a 10 - 13.
