Oud building: step-by-step

sabbassi - 10-14-2010 at 10:22 AM


I would like to share what I have learned in the past and still learn everyday with all the oud lovers and builders.
My special thanks goes to Khalid Belhaiba in Morocco, he is real oud master builder in our time.

There will be many aspects in my oud building process that other builders may have different opinions about, any critisim or advise is welcome as long as we respect each other opinions an way of working.
Also, In my opinion there are no oud secrets, every oud maker build the way he think is best of course by respecting some basic rules that are common in in the oud. like measurements, wood quality etc. (my couscous will not taste the same as my mother's, even If I robocopy here)


The purpose of thisproject is to build a good looking oud that sound like an OUD. I will talk about wood, glues, hideglue, soundbaords...

I will make as much pictures as I can and even some videos from time to time. (difficult to hold the camera and work :)

So let's get to business.

This will be a very interesting thread Samir...thanks for sharing and looking forward :applause:

The Wood


I will not talk about all types of wood that are good for oud building, simply because there are so many.

a good wood for a first time oud builder, would be African mahogany or simillar wood. but there some expensive type of mahogany, like Cuban and Honduran. any accoustic wood that can be bent is fine.

there some kind of woods thar are famous for the accoustic quality like, Brazilian rosewood, Indian Roswood, Maple, High grade walnut etc.

for this project, I have chosen, High grade Indian rosewood and Flamed maple for the bowl. I will talk about the other components as I progress.

I have purchased a nice block of aged maple like this one:



aged maple.JPG - 74kB

so you need a good planner and and a saw table of course:

Final measurement as you see in the picture;
length: 70 cm
thick: 4 cm
wide: any one will do: I think this one is 18 cm. enouph for one oud. I have a professional thin kerf blade that save money and wood :)

ribs sawing

sabbassi - 10-14-2010 at 10:56 AM

Sawing the ribs out of the block.

This wood is already couple of years old, this is very important or it need to be dry enouph so the wood will not move much when the oud is finished. the wood is always a life.

after sawing the ribs, I leave them in the working room for 2 or 3 weeks before starting the oud build.

The thikness of the ribs is about 3 mm when resawing. by the way, this is a dangerous mater as the wood block get smaller, the hand and finger are closer to the blade. I always use wood pushers, safety glasses and dust mask. you should take all the security mesures or have at least some experience with wood sawing.

I will reduce the thikness to 2.5 mm later with a small thikness planner.

saw ribs.jpg - 65kB

I will do this for the maple and the Indian rosewood.
I need about 21 ribs(2 extra). The bowl will be made out of 19 ribs. 11 Rosewood and 8 maple.



21 ribs.jpg - 78kB

You notice some pen stripes on the maple. I have the same on the rosewood. Before I saw the ribs I design a triangle on the wood, this way I know which rib is which for the esthetic of the oud later(like book matching). I will come back on this one later.

Danielo - 10-14-2010 at 11:26 AM

Great idea Samir !

I'll follow closely this thread.. It'll be a classic for sure :xtreme:

sabbassi - 10-14-2010 at 12:15 PM

Thank you guys,

Working with flamed wood is always a challenge, specialy maple. Maple tend to bend back after a while. so it need always some adjusements when mounting the ribs.
Issue number 2 is thiknessing. a thikness sander would be perfect but as I dont have one, I use a miniature thinknesser, but it damage the flamed wood sometimes because of the structure (waves). so the trick is to wet lightly the wood and wait 10 min before thiknessing.

issue number 3 is flatening the ribs with the planer. the edge of this waves becomes little holes if the planes is not rasor sharp and just about extended for shaving.

Preparing the purfling

sabbassi - 10-15-2010 at 03:54 AM

I have also have cut some Cherry and ebony blanks to make the purfling for in between the ribs:
the cherry will be used fot the roswood\mapel oud, the ebony will be used for another flamed maple oud I'm building at the same time.

this purflings are about 0,9mm. the smaller and finer they are the nicer the oud will look. It's like jewelry.

purfling.jpg - 80kB

Bending the Ebony is difficult and time consuming. ebony is very breakable, so you need lot of heat and patience.

Microber - 10-15-2010 at 04:30 AM

Hey Samir,

That's the kind of 'feuilleton' I like to follow. :applause:

Furthermore, an oud made of flammed maple with ebony purfling... hmmm. It's gonna be a delectable one.

sabbassi - 10-15-2010 at 07:15 AM

Hi Robert,
Thanks, I Iike also the contrast black and white. I may call it black and white. :)

here are all the ribs for the 4 ouds I'm building this time. from left to right
Indian rosewood, indianrosewood/flamed maple, flamed maple, Brazilian rosewood

Neck and tail blocks

sabbassi - 10-15-2010 at 07:33 AM

the neck and tail blocks are also ready. you can also see the tools I have used to make the blocks. You also need a hand saw.
the neck block is made from high grade mahogany, the same they use for the guitar and the tail block is made from russian triplex beechwood, easy to work with, very strong.

neck block process.jpg - 155kB tails and neck block.jpg - 103kB tail and neck block.JPG - 48kB

the neck is 14 cm wide and high. the same for the tail exluding the space for the last 2 ribs that finish the oud at the end. so the tail is actualy 14cm + the last rib. the last pictures shows this.

Ribs layout

sabbassi - 10-17-2010 at 11:26 PM

The marks on the ribs I have made before help me recongnize the ribs and make the pattern I think would be nice on the oud.
Also drawing a line and numbers at the back of the ribs help outlining the ribs when mounting them, this way I will achieve an exact shape on both sides of the oud.

Continues

sabbassi - 10-18-2010 at 12:00 PM

the neckblock and the tailblock are mounted on the air-mould
the flat part of the neck block is at one level to the bottom of the tail block.



the first 3 Ribs are bent and cut close to the line drawed before and finaly planed smooth to 45 degree




The first 3 Ribs and purflings are joined with glue simply by a thin rope, this will be the base of our oud. the rope make a super join without any gaps. It was hard to learn, but with practice things become easy this way.



3 ribs are mounted, when the glue is cured, I added 4 and 5 eetc...
the neck block and tails are marked by pen and devided by exact space to the number of the total ribs. except for he last 2 ribs at the tail block

ExtreamTarab - 10-18-2010 at 02:17 PM

This is becoming very interesting...I think your "air-mould" way is the most challenging and needs lots of practice and experience, I'm not an expert it just looks like that.
Plus it's the first time I see the ribs being glued together outside the mould, pretty interesting as well...

However, did you skip the bending step...why ?!

sabbassi - 10-18-2010 at 11:20 PM

ExtreamTarab
I didn't skip it on purpose. mY camera wasn't ready that time. I will make new pictures of the bending process soon.
this building methode need indeed lot of practice, but it gives lot of freedome to make any shape (iraqui, Syrian, Traditional Arabic etc..). you are not stuck any more to the one or two traditional moulds you make.

Alfaraby - 10-19-2010 at 01:12 AM

Excuse me dear Samir, but do you think building a bowl is a "free" practice ? Would bending in any method bring up the same sound ? Isn't there any influence, as to the the sound, once you make this bawl or another ?
This is really confusing !

Yours indeed
Alfaraby

sabbassi - 10-19-2010 at 01:41 AM

Dear Alfaraby,

As I have satated before, the oud measurement need to be respected of course. like depth and lenght. this oud 2 ouds for instance will be 50cm long and 35 maybe 36cm wide.
In my opinion, no 2 ouds are the same even if you make them using the tradional methode, same wood, same workin process.
the soundbaord is the key player, the bowl also play a role in a the sound of the oud, but minimal. the wood used is more important, it define the oud charachter.

thanks

Samir

Flamed maple

sabbassi - 10-19-2010 at 11:51 PM

Thank you guys for you nice comments it encourage me ..
I couldn't resist finishing the maple oud first. I will continue with the other one with more pictures the construction.

I have finished he bowl 2 days ago, the paper strips with hot glue are in place after thoroughly romoved all the glue and dirt inside.
The bowl is sanded with 80 grid sanding paper and some scraping to remove little dunes where the ribs join.

The bowl is excalty 50cm long 36 wide and 18 cm deep. this measures could be changed a bit with couple of mm when mounting the sound board. I will aim for 50,5cm and 35,cm

the flamed maple waves follow each other and make nice circles all over the bowl. the ebony purfling and back circle add some extra to the oud.

The Bowl is also flattened to 100% flat table.

there is one thing that some LUTE builders in Belgium do, is to lower the area around the pickguard of the bowl by 1mm or two make the plucking area high enouph for the risha. but the sound baord will be little curvy at that place. I may try this another day.

I have showed in another thread before how the paper strips are glued:

SamirCanada - 10-20-2010 at 03:52 AM

You work soo fast man.
is that what you do for a living or you just have a lot of time after work?

How many days did it take you to finish that bowl?

sabbassi - 10-20-2010 at 04:11 AM

Hi Samir

:) no this is not what I do for living.
It take about two days to build a bowl. But there is lot of preparation to it, like measurements, sawing, tuning and planing. and don't watch much tv.

In the summer it take take less time because of the warm weather, the glue take less time to cure.

there is a french proverbe: C'est en forgeant qu'on devient forgeron - it is by forging (i.e. making horseshoes) that one becomes a blacksmith.. :)

SamirCanada - 10-20-2010 at 05:40 PM

Justement c'est bien dit... et en effet mon homme, tu forge :)

2 jours... ca me prend 2 semaines... minimum.

You must have developed some techniques for speed because that is really phenomenal work rate.
Also, can you describe how you go about cutting, bending and fitting the liner strips in between ribs? thank you.

maker - 10-21-2010 at 02:09 AM

Hi sabbassi

Any kind of glue you using ?

paulO - 10-21-2010 at 10:34 AM

Dear Sabbassi,

That maple looks flamboyant and the ebony separator strips look so cool and rich. Excellent work, thanks for sharing.

Regards..PaulO

liner strips in between ribs

sabbassi - 10-26-2010 at 11:51 PM

Thanks paolo, it is indeed a nice combination.

maker, I use Titebond glue.

Here is a picture showing how I bend (very traditional), and how I put the liner strips in between ribs., I first glue both sides of the ribs (not the strip) and startjoining them using the tape. it is an easy process, as long as the ribs are 100% flat to eachother.

Flamed oud

sabbassi - 10-27-2010 at 12:13 AM

In between, I have cut the sound holes, mounted the soundboard and the neck for the flamed maple Oud.

scraping and sanding the flamed maple is difficult, but after couple of hours of intensive sanding up to 600 grid, the maple become very nice.

I have also appllied a combination of two light thin coats of stain . the wood came out beautiful (goldish), I have also applied some frensh polish.

The neck is also flamed maple....

Kelly - 11-8-2010 at 02:04 PM

Hey Samir
Beautiful work on those bowls. I love that flamed maple and the sound board looks great too.
Do you mount the bridge after fitting the soundboard to the bowl? is there any advantage to this- string height/string line?
What scale length are you making for?

Best regards

sabbassi - 11-11-2010 at 01:49 AM

Hi Kelly,

Thank you. I always mount the bridge at end of the oud building process. it gives much more flexiblity, as the lenght, lining etc...I don't think mounting the bridge to soundboard before fitting to the bowl is good Idea. it need to be adjusted also to the fingerboard.
the neck is 19,5cm, which mean the strings lenght will be 3x19,5= 58,5 from bridge to nut.

Soundboard

sabbassi - 11-11-2010 at 02:12 AM

I have choosen for this project an aged peace of cedar wood. I have sawed 4 peaces (book matched) couple of years ago and stored them in a dark dry spot in the basement and hope this will be rewarded with a nice sound.

g.jpg - 37kB

The sides are planed flat with a planner until there is no light gap between the boards.

ha.jpg - 46kB

Joined together with Titebond glue.

h.jpg - 46kB

Planned, scraped and sanded down to 2.0mm.

i.jpg - 68kB

The soundboard is cut following the bolw shape

ja.jpg - 51kB

I have choosen an oval design for the holes with a (not fixed) bridge this time. this is my first mobile bridge by the way. the centre of the big oval is 19,5 cm away from the top of the soundboard.

k.jpg - 33kB

3 holes open.

ma.jpg - 48kB

the holes are rounded (decorated) with 5 lines strips: Tulip/ebony macassar wood tripes

m.jpg - 46kB

7 braces are also in place.
5mm thick 18mm high at first place(all of them)

n.jpg - 35kB

The braces are then lowered and shaped to a pyramid shape
from top to bottom:


13mm,15mm,15mm,16mm,13-14mm,16mm,13mm

and lowered at both ends to almost 5mm, 4-5cm away to the ends.

Hi Yaron,

This oud wil be with a mobile bridge. But I can show you how to mount a fixed one. it easy.
I will post a picture.

SamirCanada - 11-11-2010 at 05:37 AM

Thanks for sharing ya Samir.

I also do my bracing in a similar way.

soundboard mounted

sabbassi - 11-15-2010 at 06:07 AM

before the soundboard is mounted to the oud bowl, a dovetail opening is made to the neck. the outlines of that frame is projected to the neck with an exacto knife for later.

p.jpg - 53kB

the soundboard then mounted, everything need to be alligned, the braces need to fit exact inside, touching the bowl but not pushing it.

the neck is then hand sawed to fit in the dovetail.

Beautiful work as always Sabassi.

This is your first floating-bridge right? Have you had to make any major changes in the design of the oud (i.e. braces) when using a floating-bridge as opposed to a fixed-bridge??

Keep up the good work.

Mehran

sabbassi - 11-16-2010 at 04:25 AM


Mehran, thanks
yes it is my first floating bridge. no major changes between this one and the fixed one. the braces are 1/2 mm thicker and the placement is to achieve less bass.

I started applying shellac and from time to time sand with 2000 grid and a filler. it's a real killer for smooth surface

Amazing work Samir. You make it look so easy. What angle offset do you make for the neck. that dove tail joint must be spot on I guess. What thickness do you sand the braces to?

Cant wait for a sound sample
