The interchangeable mandrels are designed to easily make bassoon reeds.
They are available in 3 different designs:
01 for assembly (leaves a concavity at the height of the 2nd wire)
02 for adjustment (helps position the 1st wire from the inside, without affecting the 2nd wire)
03 for work (designed to refine the reed without modifying the 1st and 2nd wire)
Price for one unit, not a kit of 3 models!!
