Wise advice, Gonzalo. Stringing a composite bow calls for its own techniques. Do you have Paul E Klopsteg's TURKISH ARCHERY AND THE COMPOSITE BOW (Manchester University, Museum: 1934 repr 1987)? Practically everything you wanted to know about design, manufacture, history, performance, and shooting techniques involving Ottoman bows, with comparative notes in an appendix with mention of Chinese, Korean, and modern (as of the 1930s) longbows. A lot of the material is excerpted from old Turkish manuals and the notes are mostly by archers who traveled and observed.
The info includes detailed instructions on stringing, and the appendix notes also explain how ambient temperature must be taken into account in order to do it safely with "difficult" bows.
