gorazd:
About using bamboo as wood core in horn bow:

I cut the core from bamboo flooring plank. The plank is vertical grain and around 8mm thick glued lengthwise with some industrial glue ( I think) - this doesnt matter in bending force ...
I grooved the bamboo/horn joint and glued it with a mixture of home made glue from cat fish bladder and cow sinew restover.
It works OK.
The only caveat - the core could not be prebended with heat - I tried it (before grooving) - with dry heat. Didnt try it with wet wood - I guess bamboo flooring wouldn stand...
So the bow is not so extremly reflexed as ussualy turkish bows.

After one year of shooting  - the bow is still OK.

Mesophilic:
gorazd, were you able to get the sinew to pull some reflex as it dried?

This makes me wonder how actionboo would work as a core.

gorazd:

Yes I get some reflex from sinew drying .
I did sinewing in three layers (korean style - combed sinew layers) and after puting each layer I tied the ears of the bow a bit stronger. I waited 2 weeks between layers.
