SCVMW 2015 – Wrap Up

Pomona College in Claremont, the location of the Violin Making Workshop.

I made it home after a great week of violin making. The workshop will continue for two more weeks, and some of the attendees will stay for the remaining sessions. Others will come and go.

This year marks the 10-year anniversary of the workshop, three of which I have spent in attendance. For the anniversary, a number of us who had attended in prior years submitted “personalized” wood curls and chips to be framed and presented to Jim Brown and to Michael Darnton.

Also for the 10-year anniversary, Jim arranged for a special concert to be held on the Saturday following the first week. Unfortunately, I was travelling home and missed my opportunity to attend that event. But the concert made a little splash in Claremont and came out in the local newspaper:

Dr. Sloan, pictured with Jim Brown on the cover of the Claremont Courier, occupied a workbench that neighbored my own. I watched with interest as he set the neck of the violin he has been making.

The best aspect of the workshop, by far, is the diversity of the people that I get to meet, and the stories and experiences they bring with them.

For instance, I met a woman who grew up in Berlin–a fine violist–who had once been an airline pilot. She married a violinist who plays with the LA Philharmonic, and he came along to the workshop with her and filled the halls with his violin music (plus, I got to hear a story from him about working with Yo Yo Ma).

There was also the British engineer who had lived in Chiswick in London, and he found that he couldn’t just sit at a computer all day long. So he bought an “old” house in the midlands–in some little village the name of which I can’t remember–where he set up a violin shop of his own. I said to him, “when you say ‘old,’ you must mean something different than when I say ‘old.’ I live in an ‘old’ house, you see; and it was built in the ’50s.” And he told me about his house, built some time around 1700, and the roof leaks into his attic bedroom. He has a little bay window in the front, just big enough for a single violin to stand in; and people can pass on the High Street and look in and see him working. All of his advertising is word-of-mouth–there is no web site or social media or facebook answering the needs of his business. The butcher is his neighbor and wakes him each morning with the pounding of the cleaver. I picture Doc Martin or Peter Kingdom from the BBC shows I see on television, and I have nostalgia for something I’ve never even experienced. Well, now I know an English maker, and he clued me in to François Denis and the Traité de Lutherie, for which I am grateful.

There was another woman who owns a foundation to help give music to those whose means do not allow for it, and she does work with Luthiers Without Borders, teaching the people of Haiti how to set up and maintain their own instruments. She first spent, I think, a dozen years in Cremona teaching herself the art of making and learning from the violin makers there. She has faithfully reproduced no less than Stradivari’s own personal masterpiece, the Hellier. There she was in Claremont, occupying the bench directly behind mine.

Of course, we had Dr. Sloan and his famous instruments; we had a Puerto Rican software engineer, a school teacher, a biologist who owns a sheep farm, and various others besides. One need not be a violin maker to take one’s fill of the lore and wisdom offered up by a dozen or more personalities, all of them different. And so my time was well-spent.

In the end, I made new acquaintances, learned new skills, and worked on quite a variety of different little projects. I snapped this rather blurry photo, just before leaving, of all the stuff I did work on during the week:



SCVMW 2015 – Friday

It’s my last full day at the workshop, and I worked until late tonight. I managed to get another bass bar clamped, this time on my del Gesu top. For some reason, this one gave me a lot of trouble and wouldn’t sit right with the glue on it even after it seemed like it fit. After about three tries, I finally got it installed.

Before I could glue that bass bar in, I had to graduate the top to the right thickness. After roughing out most of the wood, I used a kind of hand-punch similar to what Stradivari had in his own workshop to establish the graduations. How it works is this: You first screw the punch down to the right depth, then you put the plate under it and press the punch in various places around the violin plate, poking little holes into it. The plate is then planed down until the holes all disappear.

2015-06-05 14-52-55

Punching the top plate is easier than the back plate, for two reasons. First, the top is spruce and it punches easily. Second, unlike the back plate, the top is typically a uniform thickness all around, within a small margin to account for random human variation. Some makers take these random thicknesses very seriously and imagine that they are deliberate, trying to reproduce the exact thicknesses to within fractions of a millimeter in the belief that it is critical to a good-sounding instrument.

I follow Michael Darnton’s thinking and agree that the old masters probably did not intentionally do this. They simply didn’t have the precision measuring tools that we have today. In looking at the dimensions of various old violins, where the graduations have been exactly measured, we find a high degree of randomness. There are some general things, such as keeping the plate thicker in the area of the sound post, or the back plate that is generally thicker in the center than at the edges; but within the general guidelines, it is likely that the minute fluctuations we see in plate graduations can be chalked up to sheer chance.

In fact, Michael is convinced that the industrial revolution and the invention of the caliper are directly responsible for a general decline in the art of the violin– by producing copyists that unsuccessfully attempt to reproduce old masterpieces in every possible regard.

I neglected to photograph my progress on the back plate. I’m happy to report that I got it arched and am now refining the scoop and am about ready for the tedious hours of scraping ahead of me. I did, however, get this picture of the tool I spent most of my time with today:

Thumb planes are especially useful for carving arches and graduations.

Sometime tomorrow I’ll post a wrap-up and include more pictures of the work I accomplished this week. I didn’t finish a complete build, of course (not even in the white); but I should be able to finish these instruments pretty easily once I am back home in my own workshop– so long as I can keep up my momentum on them! I’m also working on a commissioned project at the moment, so I’ll post more about that as I get the time.

SCVMW 2015 – Thursday

Blister day today. If I carved plates every day, maybe I’d get callouses there, but it’s the same story every time. Most of the makers wear gloves when they carve plates, but I just put on band aids once the blisters get too sore. Band aids are the poor-man’s gloves.

Plate carving begins with the outside scoop:

2015-06-04 11-06-31

Then I make lots of wood shavings doing the long arch, down to the template:

2015-06-04 14-20-32

Next comes the five template stations for the curtate cycloids. I designed and made my own templates for this build. I’ve managed to carve about four of them here, and then they’ll need to be blended. After this, lots and lots of scraping and refining. But you can see that the plate is beginning to look like a proper violin back:

2015-06-04 20-16-48

I also carved the bass bar today. My original system pretty much entailed looking up the measurement for the bass bar, then imitating the curves I saw in other bass bars. Michael had me subdivide the bar into nine stations, then he gave me measurements at each station that include plate thickness. My plate is kind of thick, which makes for a shorter bass bar. Here is all laid out:

2015-06-04 14-34-21

And this is the result. I might still clean it up a bit, but you get the idea:

2015-06-04 15-21-18

Those two projects took all day. Carving is especially time consuming.

There were some other events worth mentioning. We had a group of homeschool kids come in on a field trip. My workstation was especially interesting, as I had all of the principal pieces of the violin represented: Ribs, neck and scroll, top and back. One of the homeschool moms asked if I drew the line around the edge of the plate I was carving and how I managed to carve over it without erasing it. So I got to explain that the lines aren’t drawn or painted but rather strips of wood that are bent and inlaid into the edge of the plate itself.

There is also another conference taking place here in Claremont, and many of the attendees of that event have wandered in, quite interested in what we are up to.

For our lecture today, Michael showed us a video on YouTube of Chinese workers churning out factory violins at lightning speed. It was a very ambivalent experience. On one hand, there were a lot of great things going on; ideas that we could benefit from. On the other hand, it was also discouraging to see. In the first place no violin maker will ever achieve the combined skills of a dozen assembly line workers who specialize in a single motion. One person installs purflings all day long, another bass bars, another graduations. Since they do no other job, their skill in that single aspect is insane. They work on dozens of instruments every week.

Michael pointed out that they had become machines, churning out tools. There was no joy in it, no preciousness nor thought nor care. Chip… glue… rub… done. Toss on the pile for the next guy.

I got thinking that I’ve made some pretty amateur violins, and they took me a long time. But an amateur instrument like mine can still be a surprising thing. Who knows what it might do, or what a musician could do with it. Those factory things, though… there are no surprises there. There is no chance that perhaps a great one is lurking among them. They are all the same, all official, all standard. How does a musician mold such a thing to his or her unique expressive needs? There are no stories and no muses that might come dancing off of those assembly lines, but in Claremont we are makers of talismans to inspire music.

Still, Michael encouraged us to push ourselves and, most especially, to finish what we begin, mistakes and all. You never know when a mistake might be a happy one.

SCVMW 2015 – Wednesday

It was a busy morning with a couple of lectures/demonstrations. The first came in response to my question about placing the corner purfling channel. Michael showed me how Stradivari pointed his purfling toward the lower quarter of the corner, and not in the middle as I had planned to do:

2015-06-03 09-29-29

You can see in the above photo how my original line was nicely centered, but Michael’s more forceful gouge mark demonstrates where the line of the purfling should really run. This gives more room for the “bee-sting.”

I used this long knife to score the purfling channel, then I removed material with the purfling pick.

2015-06-03 13-47-15

Since my knife blade is so symmetrical, I lost track of which side was the sharp one and earned my first cut at the workshop.

2015-06-03 13-32-37

Here is a picture of my purfling channel, all cleaned up:

2015-06-03 15-54-44

Some makers wait until after the plate is completely carved and sometimes even until after is has been installed on the ribs before doing this work. Waiting until the end seems a more natural approach, since purfling is, after all, finish work. But I do the purfling immediately after establishing the edge thickness.

After the channel is cut, I bend the purfling and set them in place to test for fit:

2015-06-03 16-39-17

Once I’m happy with the purfling in general, I spend time mitering the corners and lapping the pieces at the upper and lower bouts. The lap joint is nice, because that way you don’t have to measure the upper and lower purflings exactly.

At last, the purfling is installed. Note how the purfling overlaps at the top and bottom of the plate. I’ll just trim that flush tomorrow and you won’t be able to tell there is a joint there at all:

2015-06-03 19-20-17

Here is a close up of my corner work. It’s not up to Stradivari standards yet, but it is quite serviceable and will clean up nicely once I get the scoop in and scrape it all down (and add any necessary fillers):

2015-06-03 19-20-35

As you can see, my “bee-stings” are not too bad at all.

Next, I’ll carve the scoop and then work with the templates to get the plate down to the right dimensions and proper arching. At that point, it will look fairly finished, except for the hours and hours of scraping required to get all the little bumps out.

Also today, Michael and I discussed bass bar measurements and how to finish that particular piece in a deliberate and systematic way. In the past, I have simply imitated what I have seen other bass bars to be like, not understanding the system employed to reach a consistent and rational result. Michael was quite happy with the fit I got for my bass bar–since that is a difficult project to accomplish correctly–but I needed additional instruction on the shaping of the bar after it has been successfully glued to the top. I had hoped to get around to actually doing that work today but did not have the time.

There was also a good demonstration of re-setting a neck. Michael’s system for finding the exact center line, taking into consideration the idiosyncrasies of the f-holes and so forth, was quite involved and lasted over an hour. I have not taken such care in the past and will have to pay closer attention to this aspect for future builds. In practice, the system was much simpler than the explanation. 😉

In general, it was quite a productive day, and I have met a lot of extremely talented luthiers outside of my interactions with Michael Darnton. The Claremont workshop attracts the finest talent from across the world, and it’s a lot humbling to rub shoulders with them; to see and handle real instruments made by Stradivari himself, or by Guarneri del Gesu (the Jackson Strad and the Sloan del Gesu have been at the workshop every year since I began attending). I have a feeling that relatively few violin makers get such opportunities during the span of their careers.

SCVMW 2015 – Tuesday

Well, it’s time once again for the Southern California Violin Makers Workshop, hosted by Jim Brown and instructed by the prodigious Michael Darnton of Darnton & Hersch.

2015-06-01 11-56-56

This year, I’ve brought a couple of projects to work on. I’m fitting a bass bar and carving a violin neck and scroll.

Here is my bass bar in progress:

2015-06-01 11-56-25

Michael’s advice for the bass bar is to carve it well enough that you don’t have to press it down to get a good joint. It should be good enough that it could be attached with a “rubbed” joint, although we clamp bass bars traditionally.

2015-06-02 18-43-52

The bass bar stuck fast to my top after only two short rubs, then I clamped it for the night. I’ll carve it down tomorrow.

My other project is this scroll:

2015-06-01 14-46-21

Pictured above is the volute as it looked when I arrived at the workshop, and I was rather unhappy with it. The profile reminded me of a wedding cake with layers of even thickness, with a shallow slope that lacks in elegance.

2015-06-02 10-27-25

In the above photo, you can see how I have begun to put a more pronounced angle on the right side of the scroll.

2015-06-02 10-48-33

The scroll is pictured in process and is starting to look better. In the photo below, it is pretty much finished (for the record, this piece of hard maple was insanely difficult to carve. I’ve never had one give me so much trouble! It tore out like crazy, and I could never figure out the run of the grain. Look at all the flecks in it, though.):

2015-06-02 19-37-11

Michael said this looks pretty good and that I’ve got the right feel for it. That’s a good compliment. However, he also suggested that I might further improve my work by making the scroll a bit smaller. The problem is that we use templates and tend to cut to the outside of the line, which is outside of the template, which is often itself cut ever slightly larger than necessary. These little things add up to make a larger reproduction than what was intended. This scroll is almost 3mm taller than Strad’s version, and the throat gap is a bit too pinched.

Still, this is good quality carving and quite up to snuff for a violin’s head. 3mm would be a fatal discrepancy in other, less forgiving areas; but a scroll is mostly pure aesthetic, and this one looks pretty nice.

One thing that I find I am developing as I carve each new scroll is a technique for the gouge. I used maybe three gouges on this scroll, and I find that, in addition to gouging, I use them to slice like a knife and even to scrape. I can get a lot of mileage without having to switch to another tool.

Tomorrow I may have time to dove-tail this neck and prepare it for setting. I left my block planes at home though, so I’ll have to borrow some. I also hope to do some purfling and arching, if there’s time. I made up new cycloid templates for this project, and it would be a pity if I didn’t get to use them while I’m at the workshop. I need Michael to check my corners, though. Those are still dreadfully difficult.
