Sonaré Flutes - SF and PS Models

Powell Sonaré PS-601

We recently had a customer inquire about the model number of his Powell Sonaré flute.  Going back through our serial number files, we discovered that the model he owned was the Sonaré SF-5000, which was actually a very early Sonaré model.  We knew this from the model number and prefix, which have changed over the years as the line itself has...

Powell introduced the Sonaré model flutes at the NFA Convention in 2002.  The history behind the concept is explained by Powell's President, Steven Wasser, in a previous post here on Flute Builder titled The Sonaré (R)evolution (click here to read the post).  The very first Sonaré model was the SF-6000, which had a sterling silver body and Y arms.  Two SF models followed -- the SF-5000 and the SF-7000.  The SF-5000 had a nickel silver body with Y arms, and the SF-7000 model had a sterling silver body with pointed arms.  Each of these models had a Powell headjoint which was made at the Powell shop in Massachusetts.  The bodies for these instruments, which had drawn (or extruded) tone holes, were made overseas in China.  In 2006, Powell developed a new patented technology for extruding tone holes.  The new patented process, named "Zinki," was then used to produce the Sonaré bodies at Powell as well.  Powell's President, Steven Wasser, wrote:
During the first few years of Sonaré’s existence we wound up using 4 different scales made by our Chinese partner.  We ultimately standardized on a single scale – the one we though was best – but were still not satisfied.  Since the acoustics of the flute are determined first by the headjoint and secondarily by the scale, we decided to focus our engineering talents on the body.  To make a long story short, in 2006 we came up with a technology we’ve called “Zinki,” that allows us to economically extrude tone holes at Powell with our Modern Powell Scale.  Since then we’ve used Zinki to extrude all Sonaré flute bodies, as well as our Conservatory and Signature flutes.  Even Custom gold flutes with extruded tone holes are done on Zinki
This body production change also marked a change from SF to PS in the model numbers.  Model numbers are engraved on the barrel of the Sonaré flutes, and you will see in the photo below of the PS-601.


There have been several Sonaré flute models over the years, including the 301, 501, 505, 601, 708, and 709, as well as the AF-60 and AF-70 alto flutes.  The 301, 708, and 709 have been discontinued.  Additional options for the PS-705 models will be announced in the next few weeks.  For more information on the Powell Sonaré models, visit https://powellflutes.com/flutes/sonare-flutes.

Steels -- What Are They? What Do They Do?

Steels are not visible from the outside -- they are inside the mechanism tubing.

We've written several posts that include the term "steels," but have you ever wondered what "steels" are exactly?  Well, steels are a very important part of the flute mechanism, but, once the flute is finished, you really won't see them -- because they are inside the mechanism tubing.  In a previous post, Powell's President, Steven Wasser, summed up the function of steels quite nicely:
The “steels” for a flute mechanism are the axles on which multiple keys rotate so that tone holes can be opened and closed. If, for example, there are 4 distinct keys on the right hand of the flute, we don’t want all these keys going up and down at the same time, yet it would be impractical to have 4 separate steels, one for each key. There are different ways of creating independent motion of multiple keys on one steel, which include building pinned and pinless mechanisms.  (Follow this link to read the full post, "Pin Pals - Part I.)
We stopped by flute finisher Matt Keller's bench while he was finishing a 10k yellow gold Powell Custom.  This gave us the opportunity to see the steels completely separated from the rest of the mechanism.  In the photo below, you will see the complete set of steels for the 10k flute taped together with scotch tape in the flute kit:


As one might imagine, the steels are made of steel and are small rods that run through the inside of the outer mechanism tubing. As you can see from the photo above, there are several keys, and these keys are soldered to the outer mechanism tubing.  The keys (with tubing) must be aligned and positioned properly for the mechanism to function.  So, the steels are threaded through the tubing and then held in place at the posts.   Pinned mechanisms have pivot screws that screw into the posts and then into the ends of the steels to hold the steels in place.  For pinless mechanisms, steels have a screw-type head at one end of the steel to hold them in place at the posts.

The steels are inside the mechanism tubing, so when you press the keys, the keys are rotating on the inner steels.  How can you tell the difference, visually, between the steels and outer tubing? Well, the steels are steel, and the outer tubing is made from the same metal as the rest of the keys and key mechanism.  So, in this case, the outer mechanism tubing is 10k like the keys.  In the photo below, you will see a green arrow pointing to the steels, and yellow arrows pointing to some of the outer mechanism tubing.


As mentioned in the top of the post, you won't see the steels since they are inside the mechanism tubing, but they play an important role!  Steels are cut and fitted to each flute individually. They must be straight and run smoothly through the posts.  For more on steels, follow this link to watch as steels are cut and fitted to a 14k white gold flute in the previous post titled, "Building the White Gold Flute - Part 4."

Introducing the Signature II Headjoint

In our previous post titled "Signature Spotlight," we learned that the Signature flute was designed to offer Powell's craftsmanship and the legendary "Powell Sound" at an affordable price, and the hand-cut Signature headjoint was crafted specifically to compliment the flute.  The Signature headjoint is identifiable as its name is engraved on the headjoint, three lines below the logo. You will find a Signature headjoint not only on each individual Signature flute, but on every Powell Sonaré model as well.

Over the years, we've received requests for a "more free-blowing" Signature headjoint, and this year, we set out to design a completely new style headjoint known as the "Signature II." Prototypes were developed and then tested in several phases by flutists on the Powell production and sales teams, Powell artists, and Powell dealers.  The resulting headjoint was not only free-blowing -- it was completely unique.  We sat down with Powell finisher and headjoint cutter, Lindsey McChord, to learn more about the Signature II headjoint...

The Signature II is the latest in Powell's offering of headjoint styles, which includes the Soloist, Philharmonic, Venti, and Signature.  Lindsey told us that the Signature II uses the Soloist wall and the Philharmonic lip plate, which is slightly wider than the current Signature lip plate.  Those who have tried the Signature II found that it is extremely responsive and allows for clean, crisp articulation while producing a full and focused sound.

Whereas the headjoint's sound and response are apparent to the player, Lindsey gave us a special inside perspective -- literally. She shared her mirror tool with us, letting us take a closer look inside the headjoint where the riser meets the headjoint tubing. She explained that the riser is cut very differently, and that the design for the Signature II is "all about round and continuous shapes."  It contrasts from the Philharmonic, Venti, and Signature, which are cut to be more angular inside.   When we looked inside the headjoint, we could see that the bottom of the riser blended perfectly into the tubing with incredibly smooth, rounded edges.  It was easy to see the roundness and continuous shapes that Lindsey explained.  She said that for other headjoint styles, the undercutting is traditionally done on the sides only, but with the Signature II headjoint, undercutting is done completely around the bottom of the riser to achieve this smoothness and continuity. Like the undercutting, the overcutting for the Signature II is also very rounded.

What exactly does the cutting style of the headjoint mean for a flutist?  Well, Lindsey tells us that the rounded shapes allow air to go smoothly through the riser and down into the tube without anything catching the air stream.  The rounded overcutting and undercutting make the headjoint "very smooth to play."

Lindsey added that she is "especially excited about the new headjoint because it is so different from anything else."  If you're interested in trying the Signature II headjoint, click here to find our list of authorized Powell dealers in your area or contact us directly with any questions.

Replacing Headjoint Corks

We stopped in to the headjoint room as flute finisher and headjoint cutter, Lindsey McChord, was installing a new cork in a piccolo headjoint.  She showed us how to install it and how to remove it, which was pretty interesting -- especially in contrast with the flute headjoint.  We say this because after we watched Lindsey remove the piccolo headjoint cork, we were anxious to see how it compares with the removal process for a flute headjoint cork.  In both cases, Lindsey has a special tool to remove the cork.  However, she told us that when you remove the cork from a piccolo headjoint, it is removed in the opposite direction than it would be with a flute headjoint.  In other words, when you remove the piccolo headjoint cork, the cork is pushed up toward the crown and out through the top of the headjoint. This is because of the metal receiver at the bottom of the headjoint (this receiver attaches the headjoint to the body tenon). As you can probably imagine, the cork assembly would not be able to fit through the hole in the middle of the receiver (see photo below):


However, when it comes to flute headjoints, the cork is removed by pushing it down through the bottom of the headjoint.  The flute headjoint tapers as it goes up toward the crown, so it's not possible to push the headjoint cork up through the top without severely damaging the headjoint -- which you do not want to do! Take a look a the photos below to see the process of removing the corks.

Lindsey uses a special tool to remove the cork.  She starts by placing it in the headjoint, starting from the bottom

This tool is also used to check the positioning of the cork, just like a swabstick.  There is a line in the tool that will be exactly in the middle of the embouchure hole when the cork is positioned properly.

Lindsey pushes the headjoint downward toward the bottom of the tool.

And the cork pops up through the top!

A different tool is used for the flute headjoint cork. 

Lindsey removed the crown and inserts the tool in through the top of the headjoint.

With the headjoint upside down, Lindsey pushes it down toward the ring on the tool.

The flute headjoint cork is out -- having come through the bottom of the headjoint.

Finishing the Split-E


We've shared a few posts about Powell Handmade Custom flutes with a split-E, including a close-up on the mechanism and a quick snapshot from the finishing department.  You can find these posts by following this link to "Close-Up on Split-E" and this one to "Offset G and Split-E."

This week, we stopped by the finishing department as finisher Matt Keller was working on the split-E mechanism for an Aurumite 14k Handmade Custom.  So, we began to wonder... Are there differences between finishing flutes with and without the split-E? Matt told us that there are a few, and in general, a flute with a split-E takes longer to finish because it has more adjustments.  Of course, the adjustments are on the additional parts required for the split-E mechanism which you will see in the photos below:

Matt holds additional part of split-E mechanism.
The part turned over with arrows pointing to adjustments: 
felt (yellow arrow) and cork (red arrow).
Close up on cork adjustments.
Although it does take longer to finish a flute with a split-E, Matt feels that the independent motion of the mechanism's G keys can help with at least one challenge.  He explained that flutes without a split-E have two G keys that have to open and close together, as shown in the photo below:


Matt told us that the synchronized motion of these two keys can make padding them quite complicated!  With a split-E mechanism, the G keys are separate and move independently, which makes padding them a bit less challenging than when the keys move together.  To demonstrate this, Matt released one of the springs so that we could see one of the G keys open and one of them closed (as highlighted by the red arrows in the photo below):


In conclusion, we realized that there are differences in terms of materials (additional adjustments on split-E), parts, and the mechanics of the mechanisms, but the finishing process itself remains the same -- and the end result is a smoothly functioning mechanism!

Shaping the Lip Plate


This week, we stopped back into the headjoint room to meet with flute finisher and headjoint cutter, Lindsey McChord.  In a few previous posts, Lindsey explained some of the actual cutting techniques used in the headjoint cutting process.  You can review these posts by clicking here to read the "Cutting Headjoints" post and clicking here for "The Scraper Blade." 

In addition to the cutting, part of the headjoint making process involves shaping the lip plate, and this is done by exerting pressure on the plate to create the desired shape (or "slope" or "drop-off").  Lindsey uses a vise, which is a device that holds the headjoint in place and allows her to press areas of the lip plate to get the desired shape.  Although the vise is a piece of equipment, it is controlled not by a motor but simply by Lindsey turing a handle to push the wooden plate of the vise closer to the lip plate -- and this helps gently bend the metal lip plate to get the desired shape.  You'll see the process in the series of photos below:

First, Lindsey places a popsicle stick under the side of the lip plate that she does not want to bend.  This keeps that side completely in tact:


In the photo below, Lindsey shows us the space between the tubing and edge of the lip plate on the side that she needs to shape.  Ultimately, this space will decrease when the plate is bent with the vise.


Positioning the headjoint in the vise properly is crucial.  She told us that she positions it so that she can see straight down through the embouchure hole.


With her left hand, Lindsey gently holds the tubing of the headjoint, and with her right hand, she turns the handle of the vise.  The side of the lip plate closest to the handle is the side she is bending.  The opposite side of the lip plate (above her left hand) will not be bent because the popsicle stick is holding it in place.


Lindsey removes the headjoint from the vise to show us that the gap has become much less as she has bent that edge of the plate into the desired shape.


Lindsey checks the space between the edge of the lip plate and the headjoint tubing.  The popsicle stick comes into play once again as it serves as the perfect gauge for this measurement. She told us that although other commercial gauges have been made, she has tried them, and the popsicle stick really is the best.  It is the most durable, resilient, and accurate time and again.


Another nice thing about the popsicle stick is that it is wooden, so it has some give.  In the photo below, Lindsey demonstrates that she can also use it to bend parts of a lip plate very gently in the opposite direction.  In this case, she is working with a 14k lip plate.  She says that the stick is also a natural gauge for the amount of pressure she is exerting by hand.  "If the popsicle stick begins to split, I know I'm using too much pressure."


It's quite amazing to see the very simple and straightforward tools used for the lip plate shaping process.  Lindsey reminds us that, "It's because these headjoints truly are handcrafted.  There are no machines to do this -- it's all done by hand."  And, that is so very true.  With a little help from a metal vise to hold the headjoint, the actual pressure is controlled by Lindsey.  The measuring and assessment are done by hand, and then any additional "tweaks" are done by hand as well.

Shimming Pads

Shimming pads is something you may have heard about, but since most of us don't really take our flutes apart, it's sometimes hard to imagine exactly what is involved in the process.  Shimming is a technique that uses extremely thin materials like mylar to position and "seat" the pad properly. 

In the video below, we watch as flute finisher Matt Keller checks the pads on the footjoint of a flute he is padding:
