Johan Jonker Saxofoons

Resaxing

Op deze site blog ik over mijn saxofoon revisie projecten en vooral over mijn "recyling" projecten (resaxing). Doel daarvan is afgeschreven instrumenten te redden van de sloop en ondertussen van alles te ontdekken en te leren over het restaureren van saxofoons. Op mijn andere site schrijf ik over basklarinetten. Het gebruik van alles wat ik hier schrijf is voor eigen risico ;-).

beaksMeasurement marathon part 2: Chamber height and angles

The second part is measuring the course of  the chamber height of the complete set of alto saxophone mouthpieces.

alto saxophone mouthpieces From left to right the mouthpieces under test:

  • Meyer 7M medium chamber
  • unbranded french?
  • Conn Steelay 5 (my favorit)
  • Pan American 3
  • unbranded 190
  • Selmer Goldentone 3
  • Yamaha 4c
  • Otto Link Super tone Master 7*
  • Selmer Soloist E copies (one red and two blue)
  • unbranded
  • Brilhart Tonalin
  • Selmer CS80 c*

 

The following information is derived from the measurements:

  • the internal angle of the chamber top
  • the length of the baffle
  • the angle of the baffle
  • the shape or course of the chamber top

 

 beaks

The picture above shows the results of the second serie of measurements. Along the vertical axle the distance between the table and the roof of the chamber is shown. Along the horzontal axle the distance in line with the table is show, The point where the horizontal axle is reached corresponds with the tip of the mouthpiece (see also the attached picture of the mouthpiece).

There appear to significant differences; some mouthpieces show a strong S curve while other show an almost straight chamber. The grafic presentation of the chamber top angle shows variations between 20 and 30 degrees and baffle angles around 10 degrees. A few typical examples:

brilhart

The Brilhart Tonalin has a steep chamber angle of 29 degrees that decreases gradually to 15 degrees at the tipopening. Most other mouthpieces have a sudden decrease in de angle that can be seen as the start of the baffle. With this mouthpiece the point of the decrease is almost impossible to detect. 

 

meyer

The Meyer chamber has a similar but smaller angle of about 22 degrees and a baffle of about 10mm's.

 

ottolink

The Otto Link chamber show a quit constant angle of about 24 degrees and a long baffle of about 12mm's.

 

soloist

The Selmer solist chamber is quite straight with  21 degrees and a baffle of about 5mm's.

 

selmer

The Selmer CS80 C* chamber has a light S curve with an angle of average 24 degrees and a baffle of about 5 mm's.

steelay

The old Conn Steelay Mouthpiece chamber has a very straight curve of 24 degrees.

 

yamaha

The Yamaha 4C chamber has a light S-curved mouthpiece with an angle of average 20 degrees and a baffle of 6mm.
