Inspection Criteria for Accreditation

Rebuilding Category

This category covers any reconstruction, large or small, with substantial tonal and/or mechanical changes. A rebuild will not necessarily aim to retain an earlier style of the instrument and in some instances may result in what is virtually a new organ incorporating exisiting material.

It is understood that accreditation in this category requires that the skills identified within the Tuning and Maintenance category are in evidence.

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.
