Hi Jerry thanks for the break down and repair story on this chilli dipper , I have one that came with a hardish case made of cardboard covered leather. With shaped side section slab top and bow bottom-with blue velvet type material inside a case latch flip type lock and a small flip lid section for plectrums and bits inside It is very old and has suffered over time but I have had that since the late sixties , it’s a bit battered still protects the instrument tho. I am left handed and changed it round but I think with a bit of patience I can make a better job of it thanks to your videos. Another project to keep me occupied wjhile fighting cancer , I also have a 9 foot RC. Sailplane to enjoy when the weather gets better thanks once again Bob from Barkingside ,England

[@Road_Rash]

I love the sound of my bowl backs...I solved the rolling issue by putting a strap on them & not just letting them rest on my lap...if they're suspended it keeps them in a more stable position...& I play a variety of styles of music on them, rock, country, blues & even some bluegrass, though I'm not much of a bluegrass player...I think they're very versatile & they're my favorite mandolin sound...I do need to learn to work on them though...I want to buy more of them, but most of the ones available on Ebay are damaged, so I'd like to be able to buy them & fix them...I'd really love to build my own...if I fix enough of them to where I understand their construction, maybe I can make that happen one day...they do make hard cases for them, I have 2 of them...👌🏿😎👍🏿

[@sukkopera]

When in Italy you hear talking about a "Mandolin", this is the instrument you picture in your mind. I had no idea other types of Mandolins existed and only found out when I started watching your channel. So I guess it depends a lot on your culture.

[@georgetempest9627]

same here, I had never seen Gibsons or Kentuckies until the late 70's. Mandolins were always bowl back to me like the Bousouki from Greece or the Saz from Turkey. Everything around the Mediterranean was bowl shaped, with the exeption of Portugal where the A-type mandolin originated.

[@jamiej14544]

The bowl back design was the original design of mandolins in the 1880s, when they were made mostly in Europe, in Italy. Bill Monroe's first mandolin as a child was a bowl back, which he called a "tater bug". In the late 1800s, Orville Gibson redesigned the mandolin to eliminate the bowl back, which he thought was not the best design acoustically. In the early 1920s, a young college student and musician, Lloyd Loar, convinced the President of Gibson to redesign the mandolin further by emulating the features of the Strativarious violin. This was thought to be the best sounding acoustic instrument of its day. That is how we got the F-style mandolin which is the bench mark for modern day luthiers.

[@budallen1376]

Great job of researching, my friend... I think Orville vastly improved the instrument, and that student named Loar... Made the instrument a legend...

[@DavidMFChapman]

Jamie Jones Very nice history there. I’d like to make a tiny correction: the F in the F-style refers to the Florentine scroll at the top of the body, not the f-hole design of the top inspired by the violin. I know that because I briefly owned a Gibson F-2, which had a round sound hole and the scroll feature.

[@jamiej14544]

@@DavidMFChapman You are right about that! Orville Gibson originated the F style with the scroll with round sound holes. Further improvements and changes were originated by a very young Lloyd Loar in the early 1920s to emulate the Stradivarius violin. That was - effectively - the end of the bowl back design which are used these days, mostly, and perhaps only by classical musicians. Mike Marshall's wife, Katarina, is an example. A friend of mine has a bowl back mandolin with a collapsed soundboard. Maybe I will have her send it into Jerry to be fixed!

[@fongy200]

Great stuff Jerry, for all the tips and knowledge you have taught me via your channel here's a tip for you. When sanding a very thin piece protruding, use an old store card or credit card to wrap the sandpaper around. Very stable and precise. Thanks again Mr. Rosa.

[@TheGuitologist]

I've owned several of these over the years. They are good for sitting around playing solo or maybe in a duo. They aren't real loud but some have good tone. The amount of work that went into making them is a lot. Many have elaborate inlays also. BTW, "wallered" is a real word here in Kentucky too. If we say it enough, they have to add it to the Oxford Dictionary.

[@georgetempest9627]

Hey again Jerry, my mother was from Germany and studied at a textile engineering university, the little tool you have there was called a Fadenzähler (string counter) to check the quality of fabric, the world still goes by measuring strings per centimeter or inch when it comes to high quality fabric like Egyptian cotton bed sheets :o)

[@craftyria]

I enjoyed watching this. My father had a bowl back mandolin that looked just like this one. I remember he used to play and sing Way Marie (Oh Marie) to me when I was a little girl. I remember holding that mandolin and trying to play it and, yes, it was very awkward. However, I really wish I had that mandolin today. My father passed away when I was 13.

[@garyyeigh6098]

Those little strips are usually holly wood, these are works of art. Nice work Jerry.

[@brianroscoe239]

I have almost the same mandolin as this, It was given to me when I was about eight years old (now eighty-one) It is in the same condition as this, although I have just repaired it where the top came away from the bottom corner. The problem of it being stored for many years, It has a hard case now looking very tatty, Agree with you not easy to play, much easier to tune now that you can get the app on the mobile phone, you did a great job on that one, as stated earlier it has a form of paper lining blue in colour on the inside.

[@micheloderso]

Jerry, this type of instrument is the archetype of all mandolins. The outer form is like a almond and the name mandolin comes from it. Greetings from germany millimeterland ;-)

[@georgetempest9627]

Mandel, you use it for making Marzipan, yum yum!

[@shaneharrison4775]

Hey Jerry an old friend of mine did some work on one of those when I was a kid he was so fed up trying to hold it steady doing the best he could with it he ended up putting the body of the old European mandolin in a bedpan which he bolted to the work bench and cushioned with a packing blanket it did fit well and he did fit it with clamps as well and made a jig for the neck rosette keep everything where it belongs

[@edjohnson2828]

I'm addicted to your videos. I appreciate great craftsmanship and ingenuity your repairs require. I'm speculating that those stains on the top look like rust stains from old strings sitting on the top for a long period of time especially since the bridge was missing. Looking forward to your next challenges.

[@kimnoragay8639]

Jerry Lived in Japan in the 80’s. Universities often have Mandolin orchestras. Went to one…all sizes of mandolin family. There were all men and each one sat with legs crossed to hold their instruments. The concert was very nice. The Suzuki company made the bowl back then for about $100 I think..

[@RandySchartiger]

not a bad sound little bug at all! and plenty of nice work done here on it, should be good to go for a long time!

[@denniskaiser4903]

I enjoyed the repair job on the pear back mandolin that is what we Canadian call them . Great job !!!

[@alpharomeo15]

I had one of those styles of Mandolin back in the '70s! Don't remember the exact brand name but it was European! It actually had a great sound and I wish I still had it today! Oh, the memories of fleeting youth! 👏🏽 👍🏼☺ As defined in the finished product, your skillful patience is what I admire the most about your workmanship!

[@budallen1376]

The "Tater Bug" brought back some old memories for me... It was the mandolin that I learned on. I fairly hated that monstrosity!. Very aggravating to hold; practically had to sit, to play it. But, it was the cheapest mandolin at the music store in 1976... I persevered; learned what I could with it, then traded it for a Harmony Monterey A style mandolin. Then my playing took off! Going from something; difficult to play, to an instrument that was an absolute joy to work with... made you put in the extra time..because you weren't fighting to play the instrument. Thanks for the trip down "Memory Lane", Mr. Rosa... and, as always... Great job!!! Until we speak again, my friend...

[@MrBmgbluz]

Jerry, I really appreciate no matter how crappy a instrument you are repairing, you respect it. Kudos to you for being true to your profession. Great video!

[@chriswareham]

When you first posted this video I meant to add a comment describing the Turkish Baglama (often known as "Saz" in the English speaking world). It has the same flat soundboard with a domed back of ribbed strips and are amazingly cheap to buy new in Turkey, especially when you consider how much craftsmanship goes into their construction. They have three courses of strings in sets of 2, 2 and 3. The set of three is mostly for melodic lines so the extra string adds volume. The neck is like a broomstick with a flattened side for the fretboard and frets made of mono-fibre that's like fishing line. As well as the western chromatic scale, there are intermediate notes that give the true Turkish flavour to songs. Check out my favourite Baglama player Neşet Ertaş for how it sounds!

[@motorcop505]

Thanks for taking the time to explain about the Saz. I believe this instrument takes cues from the saz, oud, and gusle.

[@stephengent9974]

I guess folks were a different shape back then! Nice job. I kinda like the look of em.

[@reywashere5284]

I love how your first reaction upon getting a new blade is to try it out on your finger. Tougher than most.

[@jenniferwhitewolf3784]

I like the side trip to look at the tools in depth.

[@petery30]

Hello Jerry,thanks again for this very interesting video. This mandoline,usually called deep bowl mandoline,is the ancester of all mandolines.It was created in Naples/Italy in its final form around 1750 and is also called "mandoline napolitaine" (mandolin from Naples).It became a very popular and famous instrument all over Europe being built by extremely famous luthiers such as Amati,Stradivarius or Guarnieri. Wellknown classical composers such as Vivaldi,Mozart or Haendel have composed a lot of concerti for deep bowl mandolin which are famous. It is still very much played in Europe thanks to all these concerti and you still have,mostly in Italy,some famous luthiers building up this type of mandolin. And to play it,you need to play it sitting,not standing up! Thanks for all your interesting and passionate videos.I am an early hours fan.Pierre from France

[@thiggy1249]

Jerry, I've recently found your videos and really enjoy your patter, skill and craftsmanship. Of those tools given to you recently, the brass depth gauge is used by me in setting up depth of cut of my table saw, as well as adjusting my router cutter depth. Those three tiny Indiana planes are called infill planes due to the use of the wood which fills in the body of the plane. The plane which has the blade at the extreme end of the plane is called a chisel plane, as it is used to plane up flush to the end of a box, drawer, etc. Stan in Birmingham

[@freetdg]

I am not a musician, am generally tone deaf, and have no intention of ever building musical instruments; But listening to you, and watching you work and play is like being in the company of an old friend. Choir directors could occasionally coax what they called a tenor voice out of me.

I’m n the southern MO Ozarks also, I have a chili dipper but it’s in horrible shape. The back is split in two places from end to end. We bought air plane glue and we are going to try and fix it. It’s such a mess we aren’t sure we will succeed,but if not we tried. Lol. I recently bought an Eastman Nee Mandolin which I love. I enjoy your videos

[@PatriciaDavidsonPhotography]

I have a similar mandolin handed down to me after my dad died. It belonged to my great-grandparents. I recently had work done. It's pretty cool but like you said, difficult to play because it rolls!

Many thanks.

[@daveyjoweaver5183]

Thanks Much for another appropriate for me great video! This was great for me since I have one very much like this mandolin. I am a cabinetmaker by trade with lots of hand tools. There is separation in the back about a dozen places and much of the inlay is missing. Very nice perfiling though. Mine has three strings per note and the tuning peg knobs are pewter. I've had it since the 70s when I purchased it for $35. So this is how long my one day I'll fix this time has been. May be now you have inspired me to finally get this "wall decoration" finished. I don't know if I want to spend the time restoring the inlay or not. This one is real tortes she'll and ivory. I do have some piano keys from a 1860s rosewood piano. Many years ago it was in a falling down house, veneer mostly off but a very elaborate Victorian Civil War period piece. What it was doing in a old simple frame house? Who knows?

Hi Jerry, I have a mandolin similar to that, made by Cesare Montaldi in Italy, just needs a little work to make good. I must get round to it one day. Keep up the good work.

[@joesimon2018]

Sometimes I work spruce sawdust into a crack and then wick in thin cyanoacrylate into the crack filled with spruce sawdust. The fibers and glue fill in the crack creating a dark line that looks like a heavy grain line that's as strong as the wood but might not be cosmetic on light wood. But it's invisible on dark wood and might be better looking than a splint of wood

I made those kalimbas for each of my two sons. After seeing Jerry's first mando I realized that those kalimbas have never been played.

I'm just use to playing these gals because those are the ones that I have always played. Tom's belly gets in the way when he plays my gals so he usually sticks with the mandos that he has and one of them he made he made himself! Its peas and carrots at our house or apples and oranges. If someone is desperate we can play each others.🤠🤠

Jerry, the depth gauge at 49:00 is to set the height of router bits or table saw blades. Yours looks to be brass. They are typically aluminum to prevent damaging the cutting blades.

That mandolin was made by the famous Larson Brothers. The fretboard and soundhole binding are dead giveaways (1/2 the thickness instead of full thickness). Actually, the binding is missing from the soundhole but you can see the shelf where it used to sit at 4:16 Look it up.

The Washburn book states that the 1630 became the 1636 after 1917- so that dates it as post-1917. It has 21 rosewood ribs- there was another model with 28 ribs and 36. Many Washburn mandolins were actually made by Regal for Lyon & Healy. It gets very complicated with L & H ultimately selling out their stringed instrument business and trade name of Washburn to the owners of Regal in the late 1920s- Tonk Bros who also outsourced production to other makers.

The top must have been under considerable tension for the crack to not want to close. Inserting the sliver of wood improves the appearance and probably relieved that tension.

Plus bamboo is free if you're willing to climb over a few razor wire fences and make no noise (I would saw the stalk when a plane went overhead). Free. You have to meditate (if you can) with the bamboo and ask its permission for a culm or two and it will let you know which culms (stalks of giant grass) want to be an instrument. Plus the music of bamboo leaves in the breeze is unparalleled on earth. Bamboo is considered a nuisance by many folk in L.A. because it grows like crazy and literally tons are cut down and thrown in landfills (Compost or Die) instead of making huts for the homeless. And yes a Sharpie is a valuable luthier's tool.

[@philipanastasi9840]

I had one of these which I bought 50 years ago for the equivalent of about 2 dollars from a pawn shop. I tried so hard to play it but it kept breaking strings. It was made in I think 1846. Finally, in a fit of frustration I hurled it a wall and it broke into a hundred pieces. The label inside said Amati. I shudder to think what it would be worth today. I wish there had been a Jerry Rosa then.

[@stevevaughn2040]

This is four years old and I was messing with my old mandolin. You are dead right about playing it, rolls around like playing a turtle. I need to open tuners, mine (May Flower) has metal shield on back. The kicker is the one I have was played during its career and sounds very good. It is simply difficult to hold, has to be laid face down cuz it rolls... I do want to put something on face of body to protect it because the finish was worn off from play. Any finishing suggestions would be appreciated.

Well, I got a book! If anyone is into the history of it along with Jerry's magic touch. "2044" is a special serial number, maybe because they were becoming kind of a specialty item. Mandolin numbers otherwise had climbed above 220,000 by 1915. The model 1630 was produced starting in 1917 until bowl-back mandolins were discontinued in 1924. Best guess: 1919. Thanks, Jerry!

Hey, I play these mandolins because I do not own a flat one. I have build my own one and the trick to play while standing is very simple: - Use a rubber-towel or window-lether-towel between the back of the mandolin and the belly. .. simple and standard in Europe. I prefer the german mandolins and build one by myself. Here You have to wait a long time to get one if You ask a luthier. They would like to get around 3000 - 4000 € for one. I have build my one in around 50 hours with less strips. The Bowl-back-Mandolins are based of the lutes. As the Strings were very expensive in the midage, so only very rich people or the family of a king was able to play a mandolin. The natural strings (cat-bowel) get broken very fast. The other people prefered to play the fidel. Because of the richness of these mandolin-players in the barock-times, mandolins are more decorated compared to other instruments. All these ornaments are based around this time. After the revolution in france, - I believe a lot of mandolin-players died under the guillotine. Some years later new metal-string get more popular and the fidel as a "violin" got its better popularity. much much later ... Folk-mandolins were born. Technically, these italien mandolins loook mostly awful inside. I have seen braces which look like a spline from a fruit-crate. The body is very small but they sound nice in a orchestra because the used flat-wound-strings and tone is very soft and has not that many overtones of bluegrass-strings which are made out of bronze. If You need a solo-instrument, You need an instrument which is a bit bigger than the neapolitan-mandolins or the back and top has to be improved. That way, I would say, the Roman-Mandolins ( Embergher ) have a worth pricing. German Mandolins with the much bigger Bowl sound amazing in an orchestra and as Solo-Instruments as long as they use the Flat-Wound-Strings. If You need an instrument which competes with a Banjo in a Bluegrass-band, then You need Bronze-Strings and a more open tone. I believe, the development of the mandolin-family has not stopped. It is still going on and more diverse than the development of the guitars or other String-Instruments.
