Kunti Hole Bushing

Sitar Factory Posted on by


A sitar tuning peg or “kunti” works on the basis of friction. The peg is conically ground and is clamped into a conical hole. After some time, the surfaces will wear out and the peg will go deeper and deeper into the hole. Eventually it comes out deeper and deeper on the other side.

Usually the sitar pegs are made of a hard wood (ebony or rosewood or sheesham) and thus the hole in the neck, which is made of a softer wood (tun or teak), will wear out.

Time to mount new pegs that are a bit thicker. But actually there is nothing wrong with the original tuning pegs. A solution is to provide the holes with a new layer: the kunti bushing.
For this you can use sandpaper of a good quality. The back side, which is made of strong paper, can serve as a layer of wood while the rough sanding side provides an excellent adhesion inside the hole.

It is a matter of cutting out a well-fitting piece of sandpaper and gluing it properly into the hole. Make sure that the sandpaper fits perfectly and does not overlap. Also make sure that no glue gets between the kunti and the bushing. The glue should only be sitting between the rough sandpaper-side and the hole in the neck.

You can use the peg itself to fit the sandpaper in the hole and as a clamp to keep the sandpaper in place while drying.
When everything is dry, you can cut away the excess piece of sandpaper with a sharp chisel.

In this way, the original pegs can continue to be used.

Keep in mind that this bushing will have to be replaced after a while. The paper will wear out faster than the wood of the neck. It is best to look out for professional quality sandpaper. Then you will be at ease for a long time!

Makhan Lal Roy sitar surbahar repair

Sitar Factory Posted on by

Here is an old and worn Makhan Lal Roy & Son sitar with numerous defects coming to my shop. It is a very rare surbahar style sitar with very little decoration. I have no idea about the age of this sober beauty but she has clearly been through a lot.

View the main list of defects:

    • Neck plate is loose
    • Joint is loose
    • Pardas are worn
    • Pegs are worn & greasy
    • Tarav holes are broken
    • Tarav mount on tabli is broken
    • Lacquer on tumba is damaged

Additionally there are a few small things to do and finally new strings to be mounted & jawari done…

Unfortunately the owner decided not to have repaired everything at once. The cost is too high. The original tarav strings mount remains broken and the strings itself are attached to the main string mount as done on ordinary sitars, across the tabli. The lacquer has been cleaned thoroughly but remains as is. So I expect this sitar back sooner or later… but for now she is ready to be played on again.

Benares tanpura repair

Sitar Factory Posted on by

One day I received a quite damaged and almost demolished tanpura. “Children have been playing with it…” was the comment of the owner. I wonder what game they have been playing, but it was certainly not a peaceful game. Or, at least at some time it went out of hands… as one can say?

The tanpura seems to be an old instrument, bought in Benares in the 70’s. It shows already some diligent life-signs, sensations and similar repairs. As such the gourd looks impressive. I will aim to maintain this mood. Just regain its spirit. That’s where it’s ever made for…

I started to remove every worn leftover hardware piece and glued all the cracks in the wooden body. There were many! And, even the tabli has completely come loose.

I restored some deco’s and took advantage of the situation to create some extra goodie carved into the celluloïd: an OM sign, in the middle of a simple repetitive circular design …

After that, some body cleaning and leveling has been performed followed by rough color matching. Mahogany as well as gulanagari red have been applied before, so I used it again now. Followed by a thin and fresh new protective shellac finish layer, treated with bee wax to regain it’s aged expression.

Doing jawari & mounting new strings to conclude…

Note: this is a large female size (35inch) tanpura.

Sound sample: Play Benares tanpura

The scale (open string length) of this slim instrument is 90cms and it is tuned to F#.

The string set is
1: 0,41mm bronze string tuned to C#3
2: 0,30mm steel string tuned to F#3
3: 0,30mm steel string tuned to F#3
4: 0,56mm bronze string tuned to F#2

Drowned Sitar

Sitar Factory Posted on by

More than one year ago, an awfull sitar was brought to me. At first sight it looked like it was burnt, but actually it was only drowned for some time. This sitar was stored in a basement which has been filled with water due to an inundation. Only after some time it has been rescued and luckily it was protected by a good fiber case. All the strings and hardware got ruined. The damage to the tumba was horrible but the neck seemed to have endured the misadventure well.


I removed all the hardware and pegs and started to let the sitar rest and dry up completely for almost one year. Then, after some time, the tumba’s lacquer finish started to peel off. So, I removed everything which was hanging some loose and made a new build-up. Fortunately it was a decent tumba, sturdy and round. Then colouring and a fresh full-scale shellac finish finally made it look like a new… real good Srishti Musical sitar.

Tumba cosmetics repair

Sitar Factory Posted on by

It began with an ordinary crack. Yet another case of overzealous luggage handling at airports. Very regrettable, but in this case it revealed an underlying and overwhelming problem.

A tumba is made out of a gourd, which is a natural product. As it grows on the field, the shape becomes more or less irregular, as squiggly as nature can be. But in a musical instruments setting this isn’t always very usable or good-looking…

Thus here and there some cosmetics are necessary to give it a more practical, handsome round shape. To obtain this, in general, plaster is applied. But sometimes regular plastering isn’t adequate. When more than a couple of millimeters difference in levelling needs to be adjusted a heavier and stronger filler is needed. Then sawdust, wooden dust, water and woodglue are well mixed and applied prior to the plaster mixture.

On this sitar it seems that the mixture has been made with a persistent shortage of glue. And, secondly, really a massive amount of this poorly mixed material has been used. The obvious reason for this is that the original tumba was of a critical quality. Now it is clear that it is just too thin and weak. At several places the tumba is hardly 2mm thick.

Thus, when repairing the crack, more and more chunks of almost already pulverised wooden dust filler simply fell off from the tumba. Finally, almost the complete surface seems to be covered and more than 50% became loose.

In order to obtain a better bonding the plaster is mixed with woodglue as well. A lot of work…, a lot of drying time needed…, sanding, filling, drying, sanding, filling, drying, sanding…, fine sanding, sealing, colouring and finally the finishing touch with shellac.

Cavitied G.Rosul gourd

Sitar Factory Posted on by

The second tumba of this brandnew beginners G.Rosul sitar has been affected by worms. When the instrument fell down to the ground one day, the gourd got severely broken. Close examination revealed that a big worm has been digging a lot of tunnels through the gourds soft & dry flesh. At some points only the very thin outer peel (hard crust) has been left making this tumba extremely fragile. Where and when this worm got in and out the gourd is hard to find out. But certainly we don’t want this kind of destructive parasites inside our beloved instruments, nor in our house…

The repair of it started with filling up most of the tunnels with a mixture of fine wooden sawdust, water & woodglue. After that the outer shape could be restored using a mixture of wooden sanddust, plaster, woodglue & colourpigment. Finally came the sanding, colouring & the finishing with lacquer.

At this point I would like to notice that nowadays on more and more (cheap) sitars a synthetic sprayed lacquer finish is applied. The problem is that these synthetic solvents react very different with colourpigments that are used in the traditional shellac finish procedure (french polishing). Even worse, shellac doesn’t attach well to these chemicals. One is obliged to start determinating the kind of chemicals used in this spray, and look for eventual available alternatives which can be applied succesful to it. And I didn’t even mention the bad health aspects which might come along when working with these cheap synthetic mixtures…
But, what to do ? Just don’t buy it ?!! At least ask for traditional finish !!

Tuning problem: Cracked wood

Sitar Factory Posted on by

On a traditional sitar, tuning is established by pressing a wooden peg (kuti) into a hole. Unfortunately the wood on this Barun Ray sitar is cleaved. There is a long and deep split line between the baj and jora kuti. Both strings were not keeping tune anymore. The pegs got loose too easy. How this has happened is difficult to say. Maybe during a transport something has been hitting the kutis and made the wood split. Or maybe that the wood was already damaged at the moment of selection or during the construction of this sitar. Thus weakened, it may got easily split caused by the high pressure coming from the kutis being squeezed into the hole during tuning activities.

But the repair of this defect is not so difficult. First thing to do is to remove the decoration along the head. Then split the upper head plate from the latter curved neck piece.

Repair the crack with glue and, at the same time I ‘ve added a reinforcement piece of wood on the inside. On this piece the grains are running in a perpendicular direction in relation to the wood of the head plate.

Close the head and fix the deco. Finally drill the hole and clean it.

Finish with some fresh shellac and fit the kutis again. Done…

Tarav Mogara repair page

Sitar Factory Posted on by

I’ve added an illustrated report about the repair of tarav mogaras. These are small, round ducts which lead the tarav strings through the neck towards the tarav kutis. They are usually made out of bone or horn. Sometimes plastic is used.
Due to a very high tension coming from the tarav string which is laying on the rim, these ducts get used sooner or later. Finally they will break, and then there is nothing left to prevent the string from cutting into the wood.

So, sometimes, these tiny fragile pipes need to be replaced. Or, if you are lucky and they didn’t break (yet), they can be re-used by rotating them over 90°.
