Constuction's drawings of turkish and korean bows
Hello,
im very interested to build some turkish bow's (perhaps korean too). I have learned very much theorical things about this. Now i have some questions:
1. Where can i get detailed constructions drawings with measurements of the several components like wood's, horn's, sinew (length, wide, hight from the several layers) and quantity / mixture ratio of glue? Or can someone give me thin values?
2. Why are the siyahis and middle part are separately? Why not from one piece of wood?
3. Are the used glue for horn with wood and sinew with wood in quantity or mixture ratio the same?
best regards

I don't know specifically for turkish bows, but in general for horn bows glue is a defferent consistency for glueing horn to wood, and sinew to wood.
For Hide Glue (I assume it is simmilar for fish glue)
For horn to wood:
First start with very very thin glue barely thicker than water. Apply multiple coats, about an hour in between each (enough time for the glue to dry) the first few coats should be almost completely absorbed into the horn. keep applying coats until there is a thin layer built up along the horn.
Do the same thing to the wood, but just a few coats should do.
Once there is a good layer on the horn, mix up a thicker batch of glue (about the consistency of moderately thick syrup) and heat the horn and wood to make the glew on them slightly tacky, this also helps so that the glue doesn't set up to fast, especially if you are in a cool workshop. Then apply glue to the horn and wood and clamp.
I generally for this thicker glue put the hide glue powder in the cup I will "cook" it in and add enough water to cover it plus a little more. I have read to use cold water and to let it absorb in for half an hour, so that is what I do.
For Sinew:
Start with the thick consistency like for horn to wood, then add some water to get it to the consistency of thin syrup.
Apply a coat to the wood and let it dry before starting so that not to much glue is absorbed out of the sinew.

I am new to this so it would probalby be good for an experienced bowyer to check this over, but this is pretty much just a summary of what I have learned here and from the Traditional Bowyers Bible.

As regarding a core (the middle part) and siyahs, I think you can make them as a one piece from a steamed piece of wood, but this could be quite hard to do well with a bow design with non bending, rigid siyahs witch create an angle with the core. I think (someone correct me if I'm wrong) that angled area can be a weak spot in comparison with a well made and glued siyah/core joint, especially when a sharp angle is required. Sometime ago I was thinkig myself how to make such an one piece core for a Hungarian style bow, but now I think it?s just easier to do it with separate pieces.
Also the limb part of core is essentially a flat strip while the siyah has to be shaped in a manner witch will prevent it from bending, this would be quite awkward to accomplish when using bamboo for the core as in Korean bows.
And when you assemble a core from separate pieces you have the benefit of choosing the best material for the particular application, as the siyah and limb have different functions to bear.
That are my theories why that?s been made that way.
Anyway I haven?t made any composite so far! So someone with experience would perhaps explain it better.
As Evan Painter mentioned, The Trad. Bowyer?s Bible. It?s a good source, in vol. 3 there is a chapter on Korean archery by Jeff Shmidt, it contains a detailed description of replicating process of a Korean bow.
As for the Turkish bows there is of course the great book ?Turkish Archery? by P. E. Klopsteg, but perhaps you know it already:).
And finally I think there is a lot of necessary info right here on that forum, just need to search a bit through the topics.

I agree with the advice to get the glue permeating into all the materials. Some people make the mistake of thinking that hornbows are made of elements stuck together at the surfaces with glue.
Wrong. Hornbows are virtually made of glue.
Wrong. Hornbows are virtually made of glue.
The ears can be made of the core. I have done few two wood bows and glue on the ears over the bend core. Either wood on back or belly or maybe on both side will do. The ears will be laminated and hold for almost everything. And you get everything align.
I have a copy of th klopsteg book of Turkish archery. If there is an interest, let me know.

Hi guys,
it's very intersting topic u discuss here. I'm a new-made archer and am very interested in turkish bow. I've seen it here, in Ukraine, in our museum and now I'm worried abot it! Maybe could someone show me the drawings of turkish bow? Unfortunatelly I can't find it here... And want to have it so much!!!

Hello new members; There have been many discussions on the topic of dimensions of Turkish bows in the past right here on ATARN. Just read some of the old posts.
This is one by Reto, who has built some bows but we have not heard how they shoot yet. Make your first bows very light!. -j-
Maybe find those by Fransisco Alessi. He makes and sells beautiful bows.

Thanks a lot, Jack! Hope I have soon a possibility to try this bow. And that one with a gold pattern on silk I have alredy seen. It's fabulous! This pattern was made by hand? It's just a work of art!
