Korean horn bow dimentions

(1/4) > >>

Jakesnyder:
I know traditionally they used a bamboo core. I've watched some videos and it doesnt look that thick like maybe a quarter inch thick. Is that about right? Node placement is also a concern correct? Should there be one in the center of the handle and then wherever the others fall?

bownarra:
Ideally no nodes in the working limb.
The thickness of the core tapers from handle to tips.
A Korean bow is very hard to get right on your first go. Remember the taper must be nigh on perfert when everything is glued together as you have very little room to tiller.

Jakesnyder:
What would be a better style to start with? I'm struggling to find core material other than bamboo...thanks!

bownarra:
No problem. Yes I understand on the core material front...
You can use boo on any style of hornbow. I would suggest maybe a Magyar style bow with reduced handle reflex for better energy storage. Basically  the design is straight bending limbs spliced to a handle section. Length of bending section is normally around 12 inches. Then syhias/outerlimbs (mildly reflexed) of around 14 inches spliced onto ends of the bending limbs.
I've made a couple like this, they are easy to tiller and good performers. 

Jakesnyder:
Couple more questions... so the bamboo I got, once worked down will be right around a quarter inch thick. I'm guessing the outside of the bamboo will be the back of the core and the inside will be the belly of it? Does the bamboo need to be totally flat where the sinew will be applied? Or is it ok to have a slight crown? Also thickness taper it and width taper it?
I got 11 inches in between nodes. Should I situate the nodes partway down the v splice to get a 12inches? Is 12inches including cutting in the v splice or not including it at all?
Thanks for your help!
