A visit to Quimby: Organ Update

Quimby Workshops
In late June I had the wonderful opportunity to visit Quimby Pipe Organ's shops in person. In this article, I'll take you along with me as best I can on my time spent there alongside some of the most talented pipe organ craftsmen in the United States.

The Quimby Pipe Organ (QPO) facility comprises several structures in multiple locations throughout Warrensburg, Missouri. The main workshop facility and office are located just a couple of blocks away form the University campus and what I'll call "downtown" Warrensburg.

After flight and rental car delays, I finally made it to Warrensburg - arriving at the motel at 3.30 am (not the original plan!) After a few hours sleep, I arrived at their main workshop and office building and was greeted by Michael Quimby and got to meet most of his crew.

Some re-leathering is taking place on
the work tables.
Inside the main shop building there is a lot of activity. There are several workshop areas, each dedicated to different tasks, and two soundproof voicing rooms. Racks of pipe crates (mostly from our instrument) fill almost all the remaining space.

After touring this main shop facility, Mr Quimby took me on a tour of his other facilities. One of the first buildings we saw was an immense structure that houses his inventory of vintage pipework and other components, including a few complete instruments. Quimby Pipe Organs has one of the largest inventory of vintage pipework in the country, and much of it comes from Aeolian-Skinner or earlier E. M. Skinner instruments.

components for our instrument.
The next stop - just a few blocks from the main workshop - is the woodworking shop. This building is a former auto body shop, and came complete with the paint booth area and ventilation equipment so that they are able to apply beautiful finishes to the wood components, even things like the tuning access ladders they were building on the day of my visit.

Then next day was one of the most fascinating of the whole trip (granted, in an extremely nerdy way!). I was able to spend the majority of the day with Tim Duchon, the Pipemaker. He works offsite from the Quimby shops, but nearby. I came to learn that Tim is one of a very few people crafting pipes by hand in this country. I also quickly gained enormous respect for his skill (just like the rest of the QPO crew) and his mastery of his craft.

 to cut sheet metal down to size.

While I was visiting, he was making some pipes for one of our reed stops that need to be replaced. The walls of his workshop are filled with templates, forms, and many handmade tools for every conceivable type and size of pipe. In the center of the room is a large worktable where the pipes are rolled out.

This process starts from blank sheets of metal. Various alloys are used in the construction of different types of pipes; some quite soft, others hard. The large piece of sheet metal is cut down to size to fit the form for the pipe to be made.

After cutting, the sheet metal is bent around a form to make the basic shape of the pipe. This is done by hand whether the pipe is only a few inches in length or over 16 feet!

for a first attempt!
After watching this process for a few minutes, it was my turn! Tim walked me through the process of how to form the pipe, and then turned me loose to try a few on my own. Trust me - its much harder than it looks.

After further preparation work and soldering the seam closed (a task I was not able to get very good at....) we end up with completed basic pipe lengths. These will still need to have the reed assembly made and attached and then cleaned and finished in a lacquer coat.

The next day was my opportunity to watch the voicing process of reed pipes up close and personal. This was the perfect complement to spending the previous day working with the pipe maker. The voicing of reed pipes is one of the most mysterious and painstakingly meticulous arts in the realm of organ building.

 be some of the new pipes for the 4' Clarion
stop on the Swell division of our organ.
Eric Johnson is the Head Voicer for QPO and is personally voicing every reed pipe in our instrument. Eric is widely regarded as one of the best (if not the best) reed voicer in the country and I couldn't be more thrilled to have him working on our instrument!

pipes to set up in the voicing room.






When the process of voicing begins, the pipes have already been thoroughly cleaned and inspected for any flaws, and necessary repairs made by the pipemaker. After setting up a rank of reed pipes in the voicing room, Eric goes through and listens to each one, carefully analyzing many factors - its tone quality, volume, rate of speech, just to name a few.

One of the most fascinating steps to watch in the process was the work on what is called the "tongue". (This is the part of the reed assembly that actually vibrates, just like in an orchestral reed such as a clarinet or oboe, creating the reedy tone for the particular stop). These are all formed by hand from brass and range in size from several inches long to quite small, depending on the pitch of the pipe it will be used in. He then polishes and sets the curve (a slight bend) in each one by hand.

 table surface before being worked by Eric Johnson.
Adjustments measured in fractions of millimeters are what happen here, and the difference these nearly invisible adjustments make in the sound of each pipe is astounding.

Throughout the course of its history, the people of St Paul's have always been proud of its music program and desired the best organ possible, even from day one. This is evident in looking at the lineage of the St Paul's Memorial Organ from its beginning as a small, 2-maunual instrument by the venerable Hook and Hastings Organ Co in 1887 through its move to the present site and its major expansion and rebuilding by the Aeolian-Skinner Organ Co in 1969.

After my first-hand experience in Warrensburg I can say without hesitation that this tradition of obtaining the best of the best will be carried on, if not improved upon, in the present project by this amazing group of artisans that makes up the Quimby Pipe Organ Co.
