my first oud

nati - 1-11-2015 at 04:24 AM

helo everyone
after 2 years of oud playing and the comeback of an old old dream to build an instrument, i decided to start building my own oud.
i dont have any woodworking experience but i have a dream..
so, first step accomplished this morning- i went to the post and i picked up
richard hankey book...
i will read it to understand what shuld i do first..
any tips for beginning??
thanks a lot

welcome Nati
This forum will help you a lot.
I too, like you, I had the dream of building my oud and I started a few months before you.
in my argument you will find many suggestions of wise people of this forum.

if I can be helpful to you in my small experience I will do it gladly.
good job

nati - 1-12-2015 at 02:03 AM

thanks a lot eldad and faggiuols
i have sukar oud and i want to take it proflie Measures and start doing all the calculation for the end blocks.
is that ok to draw the outline of my sukar oud on a paper and take half of it for the profile?
can i be sure the measures will be precise to calculate the end blocks?

if you want to recreate an oud identical to what you have, you can proceed so.
if you want I can send you by e-mail my project (pdf or dwg as you want), made according to the rules of the book of Hankey.
let me know
bye

thanks faggiuols that will be grate. my email- netanelcohen328@gmail.com
i see you use a mould it different from hankey book isnt it?

I think you are referring to my thread that I have reported.
my oud is not built to the exact rules of the book.
I made some changes.
important is that I built neck and the inner block in one piece.
Also the mold is different.
the size of the design are those of the drawing (except for errors!).
I suggest you look on the internet, you will find many interesting sites.
read this for example ...

faggiuols - 1-12-2015 at 03:03 AM

I sent the email with a pdf.
Also let me know if you want cad.

nati - 1-12-2015 at 03:03 PM

wow impressive.. thank you
the truth is that i dont know exactly how to read it and draw it to profile pattern..

nati - 1-12-2015 at 04:50 PM

o.k! i got it and i drew the profile pattern.
next step- to buy woods.
im thinking of walnut for the ribs, the american is better then african?
any sugestions for end blocks kind of wood?

you can find measures of patter in the book.
if you are comfortable with software cad you would be facilitated.
regarding the wood depends on the idea of oud in your head.
maybe you'd look on internet which oud you like.
in the book you can find advice about wood.
for blocks I used cedrella. in general using wood not heavy and not too hard.

faggiuols - 1-13-2015 at 12:21 AM

I advise you to study a bit '.
on the internet you can find many sites where you can get information on the construction process of the oud, youtube also.

nati - 1-14-2015 at 06:22 AM

thank you faggiuols, your advice helps a lot.
i have much to learn so i will do my research to be smarter..
the construction you gave me it without the extra depth of the back is that correct?
i have read in the forum about your process with your first oud thank you for shearing with us.
so after all, what do you think it the best way to bend the ribs?
and one more question- how did you made the pattern for the ribs?

dear Nati
answer any questions via the forum is difficult.
I suggest you read the whole hankle's book that explains quite well all procedures.
as I told you before also looks my topic http: //www.mikeouds.com/messageboard/viewthread.php?tid=15214#pid10
many of the things you ask now your can understand from reading.
to bend the ribs the best method in my opinion, unless you have a special tool, you bend with the hot gun. you can find the video on youtube.
I did the patter of ribs with autocad cad. I use autocad for work for which it was simple. in each case depends on the number of the ribs of your oud. my oud is 19 ribs.
if you want I can send my draw of my rib!
do you use autocad?

eldad - 1-14-2015 at 07:51 AM

dear nati sorry for my english if you questions you can call me i live i tveriya and i will answer you

nati - 1-14-2015 at 08:22 AM

thank you faggiuols! i dont know how to use autocad i never build anything before, but maybe i will try it i see it can make life easier..
eldad it fantastic i sent you an email!

nati - 1-26-2015 at 02:34 PM

back is complete!
huge thank to eldad..

faggiuols - 2-12-2015 at 08:08 AM

great Nati

the images are not very clear, but the job looks very nice!

nati - 2-12-2015 at 03:21 PM

thanks faggiuols! i had problems with pictures size..

abc123xyz - 4-3-2015 at 12:42 PM

I'm confused by the fourth picture. It appears that you've somehow applied the edge tiles before the soundboard is on ¦ :·o

How/why did you do that?

David

nati - 4-5-2015 at 10:17 AM

helo david, what you see in the fourth pic it is not the edge tiles this is kerfing- the top will be glue onit. it guitar teqnic and i dicided to use it for the oud
all the best

Dr. Oud - 4-18-2015 at 03:36 PM

This is an oud, not a guitar. Part of the characteristic sound of the oud is because of the fragile construction with the face almost floating on the braces, but not connected directly to the rib top edge. Guitar construction belongs on a guitar. You might find your oud sounding more like a guitar.

nati - 4-19-2015 at 12:18 AM

hey richard thank you for reapleiyng!
well.... i had to learn it in the difficult way/ the sound wasent good and im taking out the face now:(:(:(:(
the reason i decided to do the kerfing is because i sew sabasy recomendeition for that and i realy like sabasy ouds..
i will take the kerfing out now and i hope i wont do any demege for the oud.
i also thinkung about to more rose holes what do you think?
all the best
neti

Dr. Oud - 4-19-2015 at 08:55 PM

how many holes does it have now? Many old ouds had only one, later the three hole pattern was used, I have seen other patterns, buy do not know what the effect is. The face produces the sound, and it seems it doesn't take much to do it as the three holes demonstrates. More holesthan three? I'd rather not.

jdowning - 4-20-2015 at 06:46 AM

Sound hole geometry may have a significant influence on the acoustic properties of an oud (or any stringed instrument). An oud acts like a Helmholtz resonator producing a fundamental frequency - due to a slug of air oscillating or vibrating across the area of the sound hole - an 'air resonance frequency' that acoustically reinforces a limited range or bandwidth of frequencies of the oud - usually in the bass.

The calculation of the air resonance frequency of a true Helmholtz resonator is well understood and is basically dependant upon the trapped air volume of the resonator, the area (or diameter) of the vent (or sound hole), the equivalent length of the vent and the speed of sound in air. A Helmholtz resonator is a rigid sphere with a rigid vent at one end.
An oud - although behaving like a Helmholtz resonator - is, of course, by virtue of its geometry and construction not a true Helmhotz resonator - it is not a sphere or even perfectly rigid in construction due primarily to the flexible sound board and the sound hole is not centrally positioned or perfectly rigid. For this reason accurately calculating the air resonance frequency of an oud is not a straight forward matter and the physics is still not perfectly well understood. The physics of multiple sound hole arrangements is even less well under stood as not only does the number of sound holes and their diameters play a part but also their relative positions on a sound board and to each other.

If you have built your oud to the proven single sound hole design provided by Richard in his book - based upon successful instruments of the past - then your best bet would be to stick with this single sound hole arrangement rather than venturing into the fuzzy acoustical territory of multiple sound holes (although experimentation is not to be discouraged!). The addition of two small sound holes will have an influence on the air resonance frequency.

Removing the guitar like kerfing should result in greater sound board flexibility and a corresponding lowering of the air resonance frequency.

Good luck.

nati - 4-28-2015 at 05:51 AM

this is it, just finished my first oud.
i took out the kerfing and made some changes in the braces and the sound is very nice now.
thanks everyone foe edvices
