TRINITY EPISCOPAL CHURCHINDIANAPOLIS, INDIANA

OPUS 78 : 3 manuals, 65 ranks

COMPLETION, FALL 2020

In April, 2018, Quimby Pipe Organs, Inc. entered into an agreement with Trinity Episcopal Church, Indianapolis, Indiana to accomplish an extensive tonal rebuild, including complete revoicing of all flue ranks, replacement of 25% of the flue ranks, and replacement of all Chorus reeds.  Upon completion of the work, the instrument will sound as if it were a new instrument.

1. Removal of existing pipework for transportation to our shop in Warrensburg, Missouri, for cleaning and revoicing as outlined below and in the accompanying Tonal Specification.

2. Regulation and revoicing of large-scale bass pipes on location; for instance, those from the lower range of the 32’ Bourdon and 16’ Principal, which will remain in-situ at the Church.

3. New or restored to like-new condition windchests for the new Great 8’ Harmonic Flute and 8’ Trumpet, built with our standard electro-pneumatic action with a valve for each pipe, and primaries as required. 

4All new wiring, relay components and winding components required for addition of Great 8’ Harmonic Flute and 8’ Trumpet.

5. Ranks of pipes from QPO inventory, as indicated on the Tonal Specification, for substitution with existing Schantz ranks.  Any existing Schantz ranks of pipes not reused in this project will be taken in trade for material salvage.

6. All existing pipework from Schantz Opus 1731 and selected restored vintage pipework from QPO inventory to be reused will be thoroughly cleaned and restored to like-new condition and appearance in our pipe shop and will be revoiced and rescaled as required to form cohesive and flexible ensembles.  Where existing tuning slides provide a good fit on any given pipe, they will be retained; loose or problematic tuning slides will be replaced in order to ensure tuning stability.

7. Where new pipework is required, it will be constructed as follows:
     a. Scales, mouth widths, languid bevels, and metal gauge for any given rank and metal content will be determined to best fit the tonal design.
     b. Spotted metal will be of approximately 40% tin and 60% lead, and will contain at least 3% antimony.
     c. Any new flue pipe longer than 4’C speaking length, except for façade pipes, will be constructed of zinc with pipe metal mouths.

8. Replacement rackboards as required for rescaled or replaced ranks of pipes.

9. Complete cleaning of organ structure and windchests prior to reinstallation of revoiced or new pipes.

10. Following installation of revoiced and new pipes, complete tuning and on-location regulation of the organ as required to correct any loud/soft notes and/or balance issues.
