THE TESTER CAN BE USED FOR EVERY REED:

Bassoon, Oboe, Clarinet.


operating instructions


The 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.


Before 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.


According 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 "dream - reeds".


You 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.

Professional musicians save a lot of time because they have to build less than before.


THE PRINCIPLE


A 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 thickness.

scale 0 - 2,5 mm reading 1/100 mm



THICKNESS MEASURING


a) reset the scale to 0

  1. press the lever on the right side down

  2. put the cane under the feeler on the left

  3. release the lever

  4. The micrometer now indicates the thickness in 1/100 mm


HARDNESS TESTING

  1. put the cane under the feeler on the right

  2. lay down your left hand next to the instrument on the table

  3. press with your forefinger the lever slowly and carefully till the cane is touched. You feel it like the trigger on a gun.

  4. stay in this position and reset the scale to 0

  5. now press the lever totally down. The wood gives way about 10 seconds.

  6. The micrometer indicates the way the ball enters in 1/100 mm.


Hard wood has about 10/100 mm,

soft about 20/100 mm

14/100 entering way corresponds to hardness 14.

You 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.


RECOMMENDATION AT THE BEGINNING

  1. plane any 20 planes inside

  2. measure and notice the hardness

  3. build the reeds and try them

  4. chose the ones

  5. now look at the hardness and memory


According to experiences pupils and students use a hardness of 14 - 19, professional musicians a 10 - 13.

The instrument is small and handy, uses a German mark dial gauge, is maintenance-free and made of rustproof material.
