Production of an organ


Consultancy/Planning - Manufacturing - Delivery/Assembly - Voicing

We are often asked how to start an organ project, or how to proceed, in order to bring such a project to a successful completion. The following lines will take you closer to the complex stages in organ building.

At the beginning of each organ building project stands the organist. He either complains about the condition of his old instrument or works on an artistically unpretentious electronium. His complaints finally reach the responsible church committee. The church committee then contacts the responsible organ-expert. After the organ-expert has confirmed the need for a new organ a concept has to be developed. Depending on the possibilities the concept is prepared by the organist and then examined by the organ-expert. Or the concept is directly worked out by the organ-expert. Sometimes the church committee approaches us directly and asks for advice and drawing up a possible concept.

When developing the concept the needs of the church community in liturgy as well as the musically artistic wishes of the organist are taken into account. If the fundamental issues such as the possible stop-list (number and type of the different stops) and the technical specifications (e.g. mechanical or electrical key action) and the desired location are fixed, we can create a façade design. If the new organ is attempted within the fundamental reconstruction of the church, cooperation with the architects commissioned by the church committee may also occur. We are very positive towards such collaborations and have had the experience that it can be very instructive for both parties.

Often it is necessary that the entire organ technique has to be drawn up at least structurally for a façade design. Together with the façade design and a possible technical design an offer can then be submitted to the church committee.


Technical design


Sometimes, however, the space situation is so difficult that it is necessary to create a visualisation. Such visualitions allow the precise presentation of the new organ in the room.




When design and offer are approved the production of the organ can start. At the beginning of the production, the exact construction drawings and the determination of the pipe designs and dimensions (pipe scales) are laid down. In jointly sound discussions, the sound details of the various stops are determined.

Our metal pipe shop will then receive the corresponding scale lists with details about alloy, design and further details. At the wood shop the construction of organ case, console, wind chests, key and stop action and wind system will start.

In the large assembly hall the organ parts are assembled and the entire organ is preassembled. Aim of the pre-assembly is to keep the installation time in the church as short as possible so that the inevitable restrictions for the community can be reduced to a minimum.



 Assembly of the organ in the assembly hall


When the pre-assembly is finished the organ is dismantled and prepared for transport. As soon as the required preparatory works in the church, such as the examination of the statics of the organ stage or a possible new paintwork, are finished, the new organ can be delivered. The number of trucks required or the number of delivery days is determined by the size of the organ. We place great importance on the fact that the employees who have built the organ in the workshop also carry out the assembly on site.

After the technical installation the time intensive voicing, the sound harmonisation, begins. A special feature of Weimbs Orgelbau GmbH is the exclusive voicing in the church. This is the only way to optimally respond to the respective acoustic characteristics of the room and to act accordingly with the pipes.

The whole building of the organ and also the voicing are accompanied by the organ expert. Parallel to the technical completion of the organ we give guidance to the community regarding a possible commemorative paper and inauguration ceremonies.

In addition to building new organs, optical and new sound designs or reorganisations of existing organs are hardly less consultative and planning-intensive.

The process described above is certainly a very ruffled presentation. Each project requires special procedures and special advice. It is not unusual that ten or more years go by from the date of the determination of the needs until the realisation date.

If you have any questions regarding a new project, a restoration, a reorganisation, a mold control, a unwrapping or the maintenance and care of your organ, we would be pleased to advise you free of charge and without obligation.
