Frequently Asked Questions

What is an instrument repair mandrel used for?


A mandrel provides internal support or a shaped working surface during straightening, sizing, forming and fitting procedures.

How do I choose the correct mandrel size?


Measure the internal dimensions and profile of the component. Compare those measurements with the mandrel specifications, including its diameter, length and taper.

Can one mandrel be used for multiple instruments?


Some mandrels may support several compatible instruments or components, while others are highly specialized. Compatibility should always be confirmed by measurement.

About The Collection

Mandrels for Musical Instrument Repair

Shop instrument repair mandrels for controlled shaping, straightening, sizing and internal support during brasswind and woodwind repair. Mandrels provide technicians with a stable form for correcting or maintaining the shape of tubing, components and fitted parts.

Mandrels may be tapered, cylindrical or shaped for a particular instrument or component. The appropriate selection depends on the internal dimensions, profile and repair procedure.

Select the Correct Repair Mandrel

Compare the mandrel’s dimensions and taper with the instrument component before use. A mandrel that is too large, too small or incorrectly shaped may fail to provide proper support or could damage the component.

Keep mandrel surfaces clean, smooth and free from rust or damage. Secure the mandrel appropriately and apply controlled pressure to avoid stretching, marking or distorting the instrument metal.
