This complicated jig accurately drills out the wood for the clamp which will be attached to the back of the Swell soundboard, and carry the pipes for the reed stop. The exact design of the reed pipes has been a complicated business, as it must blend in appropriately with the French voicing of the rest of the organ. In larger organs there would be several reed stops, each serving different purposes in the overall sound. The risk of trying to produce a compromise in one stop is that none of the objectives will be adequately met. However, we hope that what is being specially made, modelled on a stop at Farnborough Abbey, will provide all that we need.
