Ohh, i see...sorry for the stupid question...probably i was reading to fast and i didnt noticed that its only aboute sinew and horn. This is realy interesting. Maybe using Oryx horn, wich is usualy longer, should be able to obtain a bow with a longer draw?? 28''-30''? Im thinking for a long time now, aboute building a horn bow, but with wood, i find it somehow more dificult. There are so many variables to consider...maybe without wood, would be everithing a little bit easeyer.
