Inspection Criteria for Accreditation

New Organ Construction -

Tracker, Electric or Electro-pneumatic actions

This category refers to instruments that have at least been designed and largely manufactured by the applicant, though they may include some bought-in parts. Some new organs may include older casework or a small proportion of other materials from an earlier instrument.

Important

There are five main sections required to be inspected to succeed in this category. The significance of the details within each is that, while examples of workmanship may have been witnessed over and above, in every case these items will have been inspected as a minimum requirement within this category.



 

The Workshop

Casework

  • Appropriate facilities for new organ work to be carried out
  • Quality of design
  • Timber selection
  • Timber surface finish
  • Moulding and carving/fretting finish
