I started a project this fall to better understand wood organ pipes made with triangular cross section. I produced a number of triangular shaped pipes last fall after seeing a triangular flute rank up in the pipe chambers at Northrop Auditorium belonging to Aeolian-Skinner Opus 892 located there. Those pipes I made one year ago were my first introduction to building organ pipes with triangular cross section, and I wanted to take on a new project this fall to further investigate the effect of base angle and scale on tonal result.
The triangular cross section may have an actual application if the availability of the first instrument I built becomes a rebuild before relocation. Triangular cross section allows pipes to nest compactly on a windchest. Replacing the rectangular shaped wood Flaut 4' pipes of that organ with those of triangular cross section would free up space on the windchest to address a tonal deficiency by allowing the inclusion of principal scaled stops at 8' and 4' pitch in the treble sharing the first seventeen bass notes with their respective flute counterparts as was sometimes done in the nineteenth century with small instruments. I would only need to retable the windchest, not trivial in and of itself, but still so much material from the original instrument could be used in the rebuild to make cost attractive.
The triangular pipe project I completed this fall has an accidental and potentially significant outcome. I produced a pipe with very narrow scale not really knowing what to expect, and found that it became harmonic effortlessly on lower wind pressure. This needs more investigation because having a harmonic flute available to me that overblows on lower wind pressure would give an additional and useful tone color to include in the design of a small cabinet organ. And its ability to save space makes additional space available to another stop whose inclusion might not otherwise be possible.
I know of no documented example of a harmonic stop whose pipes are made of wood with triangular cross section. Let me therefore introduce you to the Flûte octaviante triangulaire as it might have been named had it come from the shop of Aristide Cavaillé-Coll.
A short video demonstrating the harmonic triangular flute and a normal length pipe speaking the same pitch can be found here.

A major source of hardwood lumber to the artisan community in Minneapolis was Youngblood Lumber which suddenly closed last April after serving the area for generations. I wrote about it in a previous blog entry. Another independent business important to me is closing at the end of the month. I was interviewed for an article that appeared in the campus newspaper two weeks ago. You can read it here.
The closing of Youngblood Lumber is obviously important to me as an organ builder. It might not be so ovbious why the closing of an independently owned bike shop is equally important unless you read the article linked to above. We in the organ community know that the pipe organ has had its own sustainability issue for some time. My experience with the 1802 Tannenberg organ at Hebron Lutheran Church in Madison, Virginia let me see an approach to sustainable design through the work of a builder living through the constraints of frontier colonial America. I believe the work of Tannenberg is applicable to my work today.
I am in the process of collecting the Tannenberg experience along with some of the reading I did to inform that experience into a coherent digital story. I hope to have it posted here in the near future.

Leaving Spyhouse Coffee today, I noticed that for the second straight week, the main entrance to Youngblood Lumber was closed. Worried, I looked at their website and found out that they are closing for good.
I built a solid woodworking reputation after moving here to Minnesota by opening a workshop on Hennepin where I built objects using wood often sourced from Youngblood. Everything built here in fact contains some type of wood sourced through them. They were a trusted partner. Even though visibly impacted by the financial and housing crisis, they continued to operate, at least until now.
The loss of Seven Corners Hardware in St. Paul was difficult enough for those of us who equipped our shops through their immense tool selection, but this is equally sad. Another tradition lost.

My design language is restrained, though my instruments are larger than chamber organs or portativs. I talk about what first formed my design language in the story linked to below by introducing two instruments that had a strong impact on me during my formative years. Those were years where I found out how I wanted to be different from other organ builders and go in my own direction.

I had been keeping a few sets of pipes in workshop storage since I began organ building. Those in the foreground of the photo above are a partial set from a vintage 4' harmonic flute rank. The pipes came from the same source I obtained the three sets of pipes I used in the first organ I built. Many of those pipes gifted to me then were damaged beyond repair because they were packaged and stored improperly by the church that originally owned them. Those who dismantled the organ unfortunately used bubble wrap. Packing straw like that which is used to store and ship wine bottles also properly cushions organ pipes when crated for storage or shipment.
In the background of the photo and mostly under packing straw is the front pipe set of a principal 2' rank I had made by a pipe maker in the Netherlands for a small organ I was going to build on spec when starting out. I got my first commission before I began building that spec organ, and these became archived material.
I really thought the stored pipes would not be of value to an organ I would build, but I held on to them anyway. Having the opportunity to deconstruct the work of Ernest M. Skinner by having the opportunity to play and research his firm's orchestral Opus 892 at Northrop Auditorium on the University of Minnesota campus places this archived material in an altogether new frame of reference though. As I think about designing a new cabinet organ for client commission, I now believe the pipes could form part of that instrument in interesting and creative ways.

A unique feature found in many of the larger Skinner instruments is a rank of open wood pipes with triangular cross section. With regular playing time on the Aeolian-Skinner Opus 892 at the University of Minnesota Northrop Auditorium, and having built wood pipes for my own instruments, I wanted to know what it would take to build a wood organ pipe with triangular cross section.
This blog entry introduces my triangular wood organ pipe project published in the story linked to below with additional entries to follow that explain various aspects of the project more in depth.

Most people who know me know that I am a pragmatic person. I build organs limited to five or six stops. To do so in a valid way requires not only good tonal and visual design, but good mechanical design as well. The organ is both significant parts art and engineering.
This blog entry introduces a story linked to below that I wrote to explain two ways in which computer technology assists my design process.

I took some time when I first set up shop here in Minnesota to develop a design language that I describe here as influenced by the Grand Avenue, Macalester College area of St. Paul, one characterized by early-century, industrial-agricultural affluence. My studio work began to take on that influence which could be described by contrasting dark woods with light, and the use of mechanical joinery apparent in dovetail or box joined constructions.
I then set out to create a structural design architecture that would form the design foundation for a family of cabinet pipe organs. I talk some about that process in the following story linked to here.

You cannot escape math and physics when designing a pipe organ. My engineering education and background lets me see important relationships between energy and sound, between structure and applied forces. Yet I consider my work to be historically referenced where to me it matters. I talk in this design blog entry about the methods I use to develop the tonal design of an organ that rely more on the work of the old masters rather than emperical relationiships.

I started the processes of designing a new organ about five years ago. I write about that here in this design blog entry on my approach to tonal design. I was thinking about building a small recital organ back then. The availability of my first organ may take me in any number of directions with the building of a new organ.

A church can often be an organization without individuals united by a common goal or purpose. No wonder then that I think about the design of a cabinet organ for a unique recital venue like an art gallery space for instance. The structural difference between an organ designed for church use and one designed for recital use is not all that different. The difference lies in tonal design as each are built for a different purpose.
Here I wrote a blog entry that took me back to an original idea I had when first starting out.

I write about the use of technology in this entry from my design blog that assisted me in the complex process of designing pipe groupings for organ case pipes. These are the pipes that you see laid out in some geometric form in the front of an organ case. I use examples from the first organ I built to describe the process and tools I developed to create a three-section front pipe grouping for the instrument.

This entry is especially relevant as I wrote about the motivation behind the organ I built now made available by the closing of a church. I write elsewhere about how the instrument may actually provide material for a new instrument. This entry details how the organ itself is the result of repurposed material designed into what became the first instrument I built as an independent builder.
