In 2016 the “Hersteld Hervormde Kerk” is building a new 900 seat church. The traditional design of this church is made by the well known Dutch architect Marco Born.

The church committee decided to install a fine pipe organ. Since many churches are closing in the Netherlands the best quality organs are quite often sold to Van den Heuvel-Orgelbouw. Van den Heuvel (trained by Dirk A. Flentrop) bought the last few years, among other organs, 5 important Flentrop organs, and just purchased a well known Flentrop-organ from the Maranatha-church in Amsterdam. The measures of this organ were suitable for the church in Ouderkerk. The customer however requested Van den Heuvel to make important improvements, alterations and to include additional (wider scaled) stops, as well as a completely new traditional organ case design with wood carvings. The organ has to be delivered in 2017.

The Flentrop organ had a traditional winding system with 4 folding bellows. The windsupply is redesigned and includes an additional wind motor and one additional bellow. The Flentrop bellows are re-leathered, also the wind trunk system will be renewed.

Pictures of the re-leathering of the bellows (7 pictures):

For the added Bourdon 16' wooden bass pipes were made (10 pictures):

To facilitate the new stops additional wind chests were made for the Hoofdwerk and Pedaal. For the additional stops on the Rugwerk and the Hoofdwerk Cornet side blocks were made to the wind chests (16 pictures):

The traditional organ case is made from mahogany wood. For this case we selected a 11 meter long mahogany trunk which was sawn to our specification (23 pictures):

 The new lower case with the pedal tower consoles is already assembled in our hall:

The console by Flentrop will be thoroughly cleaned and new bone key covering will be applied. Also new key cheeks will be made.
