Handmade Custom Choices

If you are thinking about purchasing a Powell Handmade Custom flute, there are several options and material choices that truly customize the instrument to your preferences.  Today's choices go well beyond silver and gold to include grenadilla wood and eight different metals.  In addition to the body choices, you also have different options for the mechanism material on flutes with 10k, 14k , 19.5k, platinum, and grenadilla bodies.  Whereas soldered tone holes are available on all metal flutes, drawn tone holes are also an option for silver flutes and most gold flutes (with the exception of 14k white gold).

Each Handmade Custom flute is also made with your preference for key cups (French or American), G keys (offset or inline), pitch (A-440, 442, or 444), and footjoint, (B foot with or without gizmo, or C foot).  Metal flutes may be ordered with either a pinned or pinless mechchanism.  Further customizations include the option of a C# trill, D# roller, split-E,  and G-disc. engraving, 10k or 14k tone holes, and a 14k "package' of 14k tone holes, posts, and rings.

The chart below (click it to enlarge) lists materials, options, and customizations for Powell's Handmade Custom flutes.  To view more information, download the full Powell brochure at https://powellflutes.com/sites/powell.mervideo.com/files/2015_vqp_brochure_1.pdf.

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."

Inline or Offset G

Left to right: 14k Custom with inline G, 19.5k Custom with offset G.

One of the standard options for a Powell flute is to have either an inline G or offset G.  For some, the choice may be simple.  For instance, if your fingers are not long enough to play an inline G flute comfortably, you'll probably choose the offset G.  But, is there a difference in sound between a flute with an inline G and one with an offset G?  We asked Steven Wasser, President of Verne Q. Powell Flutes, if he could shed light on this topic.  His response is as follows:

Because a flute is not an efficient converter of your air stream into sound, the tiniest things can make a difference in response and acoustics.  If we had a keyless flute where the only choice was to position the G tone hole in-line or offset, there would be no difference in intonation or response.  However, the presence of the offset G key requires a small additional rib, and additional keywork.  The independent G keys, with their additional mechanism, add a small amount of mass to the flute.  All other things being equal (ceteris paribus, as the economists like to say), there will be a slight acoustical difference between an in-line and offset G flute.  The difference is likely to be so subtle that it is not material, and my suggestion would be to go with whichever mechanism is most comfortable for you.

So, now we know the answer!  As mentioned in the introduction, the option of inline or offset G is available on all Powell flutes, including Powell Sonaré models.  Follow this link to view additional information on the Powell and Powell Sonaré flute models.

Building Bridges

Powell's pinless mechanism is found on the Handmade Custom and Handmade Conservatory flutes.  It is a mechanism that allows for different movement of multiple keys on one steel. As opposed to being pinned to the mechanism, keys on a pinless mechanism are connected by bridges.  You can read a previous post on the pinless mechanism, complete with links to video demonstrations by Powell's president, Steven Wasser, by following this link.

We stopped by the stringing department to visit with Stefania Iamandei as she was building bridged mechanisms for Conservatory flutes.  

The bridged mechanism is comprised of several different parts that vary depending on the specifications of the flute.  For instance, the left hand piece is different depending on whether the flute has an inline or offset G.  The right hand has an additional piece for flutes made with a split-E.  You will see the bridge components in the photo below.

Stefania was putting together the mechanism for a flute with an offset G and split-E when we stopped by.  We outlined the components in the photo below (left hand piece is red, right hand piece is yellow, split-E piece is light blue). The split-E section that is "upside down" on the bench does not have the long piece yet that is located between key cups, so we have that piece outlined in a darker blue on the mechanism in the photo below.

The two bridges are outlined with red boxes in the photo below.

The next photo shows a close-up of the bridges.  As Stefania builds them, she has to make sure that they have the correct fit and that they function properly.  She also has to check that the bridges (and the entire mechanism) open to the correct height, because once she is done, the flute goes to the finisher.  The finisher ads foam and cork adjustment pieces to the bridges to prevent metal-to-metal contact.

Below, we see a close-up of the left-hand bridge.  Once the mechanism meets the correct measurements and is functioning as it should, Stefania adds beveled edges -- purely for aesthetics.

The photo below shows the left-hand bridge as it will look when it is open.

In the photo below, we see another view of both bridges.  You can clearly see the tabs that function to create key motion.

Finally, we see a photo below of the bridges on a finished Handmade Conservatory Aurumite A9 flute.

Close-Up on Split-E

Split-E allows G keys to operate independently to facilitate high E.

Flutists have several options when ordering Powell flutes, and many of these are mechanical options like the split-E.  Flutes that are built with the split-E have upper and lower G keys that operate independently instead of together. When the player depresses the E key, the lower G key closes to help facilitate the high E.

Flutes with a split-E will have a few differences in the mechanism to allow the split-E to function properly.  In a previous post, we took a detailed look at the differences in mechanism tubing on flutes with a split-E.  You may read that post by following this link. Along with the tubing, there are other additional mechanism pieces for the split-E.  The most noticeable is the long, slender piece next to the lower G key.  There is also a small metal tab that extends off of the lower G key cup and a slightly different key arm, with additional pieces next to it on the mechanism tubing. These additional parts allow for the independent motion of the lower G. Because of the mechanical differences between flutes with a split-E in comparison to those without, if you are thinking about purchasing a flute with a split-E, you will definitely want to try one first to see how the different mechanism feels.  Most flutists will, of course, try flutes before buying them.  However, if you are about to purchase a flute with mechanism options that differ from the flute you currently play, you will want to make sure to test the new flute, paying close attention to how it feels.

Building the White Gold Flute - Part 7

In our last post, we followed the white gold white flute into the polishing room, where we had a chance to see Alex and Galina. Galina was the finisher for this flute, so after the polishing was done, we spent time with her at her bench.  In the video below, you will see one of many steps in the finishing process -- hand shaping corks.

The finisher plays an important part in the process of bringing the flute to its finished, playable stage. We've written a two-part overview of their role in previous posts which you can read by clicking here for part 1 and here for part 2.  We've also written about many other parts of the finisher's role, including leveling keys and tone holes, undercutting tone holes, fitting keys, installing springs, and fitting the headjoint and footjoint.  One of the central parts to finishing the mechanism is padding and shimming, which you will see in the video below.

The photo below shows the flute as it looked after Galina finished it.  You'll notice that the blue protective tape is still on the keys. This is because the flute was on its way to testers for play-ins and play testing, and the tape protects the keys from any cosmetic damage during those processes.  If the testers find that the flute needs additional adjustments, it goes back to the finisher for the adjustments to be made.

Finally, a flute would certainly not be playable without a headjoint, so we met with JoJo as she brazed the riser and lip plate onto the headjoint and cut the headjoint to length, as you will see in the video below.  After this, the headjoint is sent to a "headjoint cutter," who is the person who hand cuts the headjoint to the shape and specs of the headjoint style (Signature, Soloist, Philharmonic, or Venti).

Building the White Gold Flute - Part 6

Last week, we spent time in the stringing department with John Colvin as he fitted the keys and began building the mechanism. This particular flute has engraved keys which went to our engraver, Weiling Zhou, after John soldered the key cups to the key arms.  After the keys were engraved, they were sent back to John to be fitted to the mechanism.  In the video below, you will see a compilation of photos of the engraved keys and John finishing the mechanism.

Once the keys and mechanism are built and fitted to the body, the mechanism components (keys, mechanism tubing) are sent to the polishing room.  The body and foot joint are polished at this time as well.  The keys go through a pre-polishing step followed by two additional polishing steps.  Between each step, the keys are cleaned in the ultrasonic cleaner.  In the photo compilation below, you will see the the polishing process with Alex polishing the body and footjoint, and Galina Lavrishina polishing the keys. Galina is also the finisher for this flute, so we will take a closer look at the finishing process with her next week...

Building the White Gold Flute - Part 5

This week, we follow the white gold flute into the Custom flute stringing department, where stringer John Colvin works on building the mechanism.  Building the complete mechanism takes quite a bit of time, but we had a chance to capture a bit of the key making process.  For each key, John must take the individual arm and the individual cup, prepare them for soldering, solder them, and then fit the finished key to the mechanism.  In the video below, you will see John preparing a French (open hole) cup and arm. 

After everything is prepped, it's ready to solder:

For the cups with pointed arms, we have a few photos below of the soldering process.  The actual arm and cup are separate (just as in the videos above), so they must be prepped and soldered as well.

Building the White Gold Flute - Part 4

In part 4 of our series on the gold flute, we meet with Alex Shtyrkov, Dennis Williams, and Weiling Zhou as several steps are completed.  In the video below, Alex finishes his work in the body making process by soldering the posts to the ribs, the ribs to the body, and the rings to the body.

In the next video, we visit with Dennis Williams and Weiling Zhou. The video begins with Dennis, who is fitting the mechanism steels.  Dennis must make sure that the steels are the proper length, shape, and that they run smoothly through the posts.  In the second part of the video, our engraver, Weiling Zhou, engraves the logo on the foot joint and body.  The engraving we see in this video includes the triangular VQP logo and "Verne Q. Powell Flutes." When the body engraving is complete, it will have the following, each on a separate line: triangular logo, "Verne Q. Powell Flutes," "Boston," serial number, and karat.  The foot joint will have the same with the exception of the serial number.

Numbers in the Cups?

If you have a Powell Signature or Conservatory flute, you may not have realized this, but there are numbers engraved in your key cups and on certain parts of your mechanism.  What are these numbers for?  Well, they are actually the serial number.  The reason for this is quite simple, actually.  You see, all Conservatory and Signature flutes have silver key mechanisms, so keys and mechanism components from several different flutes may be sent to the polishing room at the same time. 

Initially, each key mechanism is fit to a particular flute during the "stringing" process.  The key mechanism and body components of an individual flute are kept together in a tray in the stringing department.  However, the keys and mechanism components are removed from the trays when they are sent to the polishing room.  After polishing, they are returned to the stringing department in preparation for the flutes to then go on to the finishing department.  So, in order to insure that the proper mechanism (which has been fitted to the flute) returns to the corresponding body after polishing, the serial number is engraved in the key cups and other areas of the mechanism.  In the photos below, the blue Sharpie marks point to the areas where the serial number is engraved:
