Hey Guido,
I don't have the experience of these other guys, but I have done one. My joints, as compared to what I'd seen done by more experienced guys, were terrible. Big gaps. I used epoxy for glue and clamped with "C" clamps to help pull joints in a little tighter (not too tight though). Next day I drilled the handle and put two dowels through the entire handle (run parallel w/ back). THEN I wrapped the handle with epoxy-soaked jute. I've shot this one quite a bit and haven't had any problems. Again, this is my only try at it... but it worked in this case.
