CNC carving a violin out of olive wood with the Shapeoko XXL

[@James-gg4ld]

I think it important to keep in mind the original premise as stated by Dennis at the beginning of the video. He wants to break with traditional violin crafting methods and craft a violin with a CNC. He also acknowledges the traditional woods that the masters used in their violins but, again, breaking with tradition using olivewood. At the very least Dennis has crafted four beautiful pieces of art that would grace any home or office and what a conversation starter! Watching the care Dennis takes with the string components [fingerboard et al] I find it hard to believe the sound will be 'horrid', but certainly as good as, at the very least, as a mass produced student violin, hopefully better. Remember, Dennis never stated that his quest was to produce an instrument rivaling the sound of the masters. What I think would be interesting would be to compare the sound of the four. I say well done, Dennis! You are to be congratulated for your CNC and hand crafting skills.

[@dennisvanhoof9958]

Thank you for concisely reiterating what others may have missed or forgotten (or maybe some chose to ignore) by the time they got to the end of the video. You sum it up quite well, and I appreciate you pointing that out. :) I think I'm just as curious to know what they sound like in the hands of a skilled violinist, and I'm working hard on that most frequently asked question answered. But the pandemic hasn't made it any easier to reach out to orchestras and professional violinists. A follow up video will be posted... some day...!

'Magic Woods' are overrated. It's like winemakers talking about tasting 'the soil' in wines. Geometry of the parts is most important, which a CNC can excel at repeating. Blind professional player tests of Strad vs modern made violins reveal over and over they can't tell the difference, which is better/worse. People listen with their eyes and there is magic in marketing.

It wouldn’t make a sound or be dull and scratchy Imagine a violin being a finely tuned automatic wristwatch compared to the watch from the dollar store Yeah, might make a sound.... but not one you’d want to listen to Also.... I’d expect it to just rip apart The strings of a tuned violin have a downwards pressure of around 27kg and the vibrations are extreme. It also looks like he didn’t install a sound post (a vertical piece of wood, roughly under the bridge that makes sure the instrument doesn’t collapse) It’s nice to look at, but as someone who plays the violin.... that’s not gonna happen

[@d1oftwins]

@@arwo1143 You are making a lot of assumptions without even a test. Yes, all of what you said is true and the violin might explode when you look at it the wrong way, or it might also not. Hence why we are asking for a test with a professional. You on the other hand are trying to sell the fur before shooting the bear, or in this case you are judging the violin before it got a chance to explode and rip apart on us while playing.

[@Dolzinfant]

@@arwo1143 He sure did install a soundpost starting at 26:55. All the same this violin will not make a great sound because the top is of hard olive wood which will not resonate in the sound range of a violin. The top is usually made of spruce, sometimes fir or similar. This is for resonance reasons. The rest of the instrument is usually made of maple. Dennis mentioned both in the video. I believe these violins were made for the fun of building some string instruments with modern tools and remarkable looks.

@@arwo1143 "finely tuned automatic wristwatch compared to the watch from the dollar store" A dollar store watch is more accurate. Actually, a cheap watch is almost as consistent as an atomic clock the size of a bathtub (consistent and accurate is not the same). No comparison to a mechanical watch.

Although I am not a violin maker, my dad was, and I learned a lot from him, and even with the background of having observed a violin maker growing up, I am impressed by what CNC can do. I think the integrated bass bar is brilliant. Also, CNC-cutting the scroll is brilliant as well. The scroll is incredibly skill-intensive to carve properly. The idea that a CNC machine could give you a nice scroll without that kind of difficulty is fantastic. I am persuaded that there's no good reason a CNC'ed violin can't be just as good as an old fashioned hand-carved violin. I also learned a tremendous amount from this video about CNC wood carving methods. Thanks for making this video.

Hello! so first off, as a violinist (non professional) and carpenter, I love that you are bringing a modern edge to this craft. A few things I noticed/information that may be helpful to you in future instruments. The ribs being milled from a single piece instead of bent into shape may affect the tone. (won't know if its good or bad until we see an expert play it!) you didn't clamp the neck. I understand the clamping issue, but without any clamping force, the glue may not have set properly, there could be small air pockets, or it could potentially just be a weak joint. on the next one, you could use some string or rope to bind it while the glue cures. you used Deft brushing lacquer for your finish. It's a great product, but its technically a lacquer, not a varnish. It's solvent based, and is effectively cured in 2 hours. I'm sure there are alternatives for animal hide glue, but every good violin will need to be taken apart at some point in its life for repairs. Last, but likely not least, I noticed that you have no purfling. (those thin black lines on the edge of a wooden violin) while it is there for aesthetics, it's also there to prevent cracks traveling from the edge through the body. Other than all of that, I think you made a beautiful instrument, and I'm excited to see a professional play it some day!

[@dennisvanhoof9958]

Thank you for your extensive and constructive feedback! Most "wrongdoings" were intentional (no purfling, the ribs out of one piece, the choice of lacquer, which is indeed not varnish, but you really don't want to hear me trying to pronounce that word with my Dutch accent, without the need for subtitles of closed captions); I consider them to fall within the artistic freedom that a non-luthier woodworker has. ;) I've used clamps for the handful of violins I made after this (final) prototype that I show in the video (including special fingerboard loop clamps from StewMac), but have moved on to completely different projects that are not even remotely related to musical instruments since then.

I question your aversion to the use of the CNC. It is capable of more consistent and reproduceable work than a human can do over a run of production numbers.

This can drastically reduce the cost to consumers for fine instruments. It is the future...

What Dennis has made is a piece of art, and as I understand is not meant to be comparable to a real violin. The reason that violins aren’t normally made with machines is that they are pieces of art, not a product. Every handmade violin is unique, and the process for making a violin is a beautiful and precise process. If we use machines to make violin making easier and more efficient, we lose sight of what a violin really is. Dennis is not trying to make a real violin, what he’s made serves a completely different purpose.

The means you use to achieve this are mere means to achieve this goal. If plastic violins sounded better than wooden ones, they would all be plastic.

[@michaelfrank4922]

@@jazzman_10 yes, technology is progress. But when you industrialize the production of many things, everything becomes the same, and part of what makes some violins and many other things so much more expensive or beautiful than others is their uniqueness, and the uniqueness of violins and other such things is so important because each player is different and needs different qualities in their instrument to be able to play the best they can. Some things should not be industrialized. That being said, factory made violins are much more accessible and cheaper, which is better for people who can’t afford a 20,000 dollar violin, but they simply just aren’t as good.

Hell, I'm a tone purist when it comes to my own instrument, and I wouldn't even dream of putting on synthetic strings and completely ruin and kill my tone and therefore the joy of playing. I recognise how to achieve the sweetest tones possible, and what it takes, and that traditional purists aren't wrong. However, even though I'm really purist with my main instrument, I believe in general that violins should evolve and develop. This is a really cool step in developing it further, and I can already tell from the sound of it that it has potential to be a really nice sounding instrument for certain kinds of music. Also, it looks great! I wouljd have loved to have one of them to use for just having fun playing at home or if doing some other, more contemporary types of music. Hell, I'd even try removing all the modern hardware and put on some proper gut strings and see what it could be capable of as a pure, untouched violin. Maybe I would be surprised? My backwards peers wouldn't even consider that possibility though. I love when people do these kinds of things. We need old masterbuilt instruments to get some of the sweet and complex tones we need for early music etc, but we also need a luthier community that is alive, and not just filled with people copying the old styles perfectly for the entirety of their life.

@@FatherSaccharine Yes you can, actually. That test (and EVERY SINGLE OTHER TEST LIKE IT) is performed on rebuilt Strads with modern strings and modern setups, identical to pretty much every violin being built today. It is no secret that synthetic and steel strings take away quite a bit from the tone of the instruments. Modern strings are NOT made to sound "beautiful" or "rich" or "complex". They are made to be LOUD. That't it. To have a violin setup in a modern manner, you gain a lot of volume and projection, but lose maybe 20-30% of the complexity and richness of the instrument. For baroque violinist, volume - and to a certain degree depending on situation - is worthless to us. We only care about tone, which is why we use different setups and different strings, not necessarily just because it is traditional. And when you play with a neck with no steepness to it, a different bass bar, pure gut strings and no hardware like rests attached to the violin, it will sound completely different than it did before, and each violin will sound WILDLY different from eachother. But if you set up the same instruments in a modern fashion, they will sound pretty much the same with just small differences. The modern setup narrows the tone of the instrument to gain volume, and makes each violin sound similar. Which is why these tests mean nothing unless you play on a modern setup. If you have a modern setup and modern strings, a Strad will sound like any other modern built violin.

I doubt the review from TwoSet would be good. The use of olive wood is a bad decision for making a playable violin because it has high density and irregular grain, thus not being resonant enough. Gluing the violin together with permanent wood glue is also a bad call, because as he noted it can't be opened in the future for any repairs. The wood-glue mistake in particular makes me wonder if the creator did much research on how to build violins at all. After all, you need to know why things are done a certain way before you change them. These creations are wonderful works of art, that's for sure, and I find them beautiful. But in all honesty they are VSOs - violin shaped objects - and not real violins.

Fine violins, guitars and pianos all use spruce as the tone wood for the sound boards. On violins and guitars that is the tops. The sides, ribs, the back and the neck, you can use the pretty woods. But pretty woods don't vibrate like spruce (light with a strong. tight, straight grain to carry the vibrations). Your violins are beautiful!!!

[@abz124816]

At some point, if it is financially profitable, someone will invent a polymer that mimics all the characteristics of spruce.

[@kylelambert8322]

I like the non-traditional methods, but I still think using the traditional glue would have been beneficial! (For repairs and whatnot)

[@michajuszczak5261]

I couldn't possibly imagine any professional violin shop taking in these pieces for repairs, so the point of using hide glue absolutely beats me

[@daviddillard4617]

I came to the comments to say this. The guy did an awesome job with the rest of the piece, the only thing that looked off to me was the thickness of the fingerboard and the use of regular wood glue. If some part of the instrument breaks, it's impossible to repair. Use of melting glue allows the pieces to be disassembled, repaired and replaced as needed. It sounded pretty good at the end.

[@mikeboyd21]

I enjoyed watching you make this!

[@banjoist123]

I know a lot of traditional luthiers consider CNC cheating, but they didn't use to accept CA glue, either, now we all use it. Believe me, if I could afford CNC, I would! As a much younger man, I hand cut the pearl for an F5 mandolin torch peghead and will never, ever do that again. A friend of mine put his kids through college doing CNC pearl for Gibson and Fender.

[@gittar]

Wordlessly, incredibly beautiful.

[@ps7880]

It was so cool seeing the violin being shaped as a piece of art work, though the sound may not be as resonant as the traditional ones since the olive wood probably won't vibrate as well as the maple wood. Great job!!!

[@nerdsunscripted624]

Original soundboards aren’t maple, they’re spruce, either Sitka or red spruce, sometimes englemann spruce. The back is maple to keep the violin strong. The olivewood may actually be better than maple in some ways (new growth maple is softer than traditional old growth) however using olivewood instead of spruce will ruin the sound

[@cosmeticdentalcare]

Wow increíble violin. You are good modern luthier

[@CaliforniaEBRDude]

Very interesting project! It seems kind of heretical in a way because luthiers have for centuries used only purely natural materials and hand work; but it is an impressive demonstration of Mr. van Hoof's understanding of the mechanics of the instrument. As some others have commented I would also like to see a master violinist play and evaluate the instrument. Thank you very much Dennis. I appreciate your work very much.

[@dalgguitars]

When you were gluing on that finger board you could have used a little pinch of table salt. The table salt keeps the boards from sliding around while clamping. Clamping pressure always makes a better joint, even though you don't need heavy pressure. An old wood worker's trick for those interested. I use it to glue on guitar fingerboards with success.

[@dennisvanhoof9958]

Thanks for the tip! I purchased fingerboard band clamps from StewMac after I finished the violin in this video: www.stewmac.com/SiteSearch/?search=fingerboard%20band%20clamp

Hey, that is really exciting to know! Tank you for sharing this insight. I very much appreciate and highly value the constructive feedback from professional luthiers like yourself.

This violin does seem to have a nice sound. I also would like to see what someone who does know how to play can do with it. It doesn't even need to be a professional to provide significant insight into the tonal character of the instrument.

Absolutely fascinating! I am neither a woodworker nor a violinist, but I watched the entire 29:38! This is February, 2022. I hope you have been able to sell these beautiful pieces! As a musician - who does NOT play the violin (keyboard, piano, some occasional guitar) - I am extremely intrigued by the use of non-traditional materials. The original woods would have ben chosen for their functions, not their aesthetics, but, additionally, olive wood would - rats, I did it again! - impossible for Stradivarius et al to use , as clearly evidenced by your use of epoxy. I would love to hear these pieces played in concert, if not to hear them then to see them! (Waterloo, Ontario, Canada).

Very Very impressive. I thought you were some sort of avid fiddler but I was shocked to find out you didn't even play! How you pulled that off without having ever used one is really quite impressive. I've been asked to make guitar's but I have no idea what I need to do to create one properly.

[@dennisvanhoof9958]

Thanks, Dan! The best advice I can give you is to read a lot about it, ask experienced experts as many questions as you have, be very critical of your own work, and don't be afraid to make mistakes. I went through 5 prototypes before I finally built one that I believed was up to the standards. I learned the most from countless of failures. You can do it!

We had a local luthier that made Cellos. He couldn’t play, but he built very good cellos. LaMay Cellos.

This looks absolutely stunning. It would probably be a pain to carve olive wood by hand but if I were a violinist and the instrument sounded good, it would be such an amazing piece of art to play

[@dennisvanhoof9958]

Yeah, olive wood is incredibly hard. Even finishing it by hand after the CNC has done the brunt of the work is finger-blistering work!

[@KOLODNY95]

Well, it may look good, or interesting, but the proof of the violin is its song. Let's hear someone who is a violin virtuoso like Hilary Hahn play it in a concerto by Mozart or Beethoven. With all that epoxy how resonant will the instrument be?

[@clairedionne559]

@@KOLODNY95 Well yes, epoxy scares the "..." from my violin playing technique and "resonance". But then again, olive wood lines, though gorgeous to look at and admire, is tortuous to say the least; I don't know how it can carry the sound at it's best capacity. But again, how beautiful to look at!

[@binomesprite7829]

Beautiful and sounds great as well

[@paulgrosse7631]

Absolutely fascinating - a rarity in that I watched it all of the way through at normal speed. Beautiful work, creating some gorgeous artwork. However, just 3 points: 1 no varnish on the neck - people's hands stick to varnish too well and the back of the neck is bare wood (from violins to cellos and into the viol family with the double bass as well (I checked mine just to make sure and mine was made around 1880); 2 the front (the belly) is usually made from pine with a nice straight grain, running from top to bottom. There is a reason for this. The speed of sound across the grain is around a quarter of that along the grain and the distance between the f holes is around a quarter of length of the body. In this way, the sound gets to the f holes and the top and bottom at around the same time (research project for a PhD in music for somebody here, finding out the actual difference in sound from the differences implied here). With a beautiful piece of wood like the one you use in this video, they will arrive at different times and affect the sound. 3 you are using normal white wood glue. Apart from the effect that you stated in the video insofar as you cannot separate the pieces afterwards without leaving traces of glue filling the pores of the wood; PVA glue creeps. That is to say that if you have a joint under stress, it will move over time whereas the bone glue joints will not. remember these instruments will last for hundreds of years (my DB is over 140yo).

[@dennisvanhoof9958]

Thank you for your kind words and constructive feedback! I really appreciate the time you took to write this down and share your expertise and insights.
