1. Sketch

Draw up a diagram localising and pointing out the damages

2. Survey

List all damages with accompanying photographs

Formulate an action plan for the restoration

3. Dismantlement

Disassemble the instrument to all its individual components

Test each of them to judge its potential to be reused 


  • Locate historical documents, images, patents of the instrument or similar variations
  • Undertake an XRF-Analysis
  • Measure the thickness of the tube walls

5. Cleaning

Clean each component with either one of the following three methods, depending on level of contamination:

  • cuproten bath and sodium carbonate neutralisation
  • mechanical cleaning with nylon or wire brushes or
  • ultrasound

6. removing dents

7. Laser Soldering

Punctual soldering the damaged parts can fix the instrument without interfering with its tension

8. Replacing heavily damaged parts 

As much as possible we'll try to use original materials and tools that correspond to the history of the instrument

9. Reassembly 

The instrument is reassembled and rough marks from the restoration are removed without erasing characteristic features relating to its history and restoration
