One of the difficulties with the instrument in its location at Grazeley was that access to the Swell box for tuning required standing on the pedal soundboards, which resulted in serious damage to some of the pipes. In the re-build, there will be new soundboards for the Bourdon and the Violoncello stops, arranged to avoid this problem. The inner workings of the Bourdon soundboard are shown in this picture. The complexity of the mechanism to get wind into the pipes is staggering!
Meanwhile, the date for demolition of the present organ draws near. We are expecting to begin this work on February 9th (1 week away).
