you have to saw down the centre, find a way to boil the half section till soft then clamp it flat, smooth the surfaces and you've got 2 horn belly laminations. some people have used the 2 horns whole inserted a wooden handle and used the horns whole, these types of bows dont shoot very well, they are more for looks.....the boiling and flattening isnt easy, at least it wasnt when I tried it....but dont take my words for it , I'm sure others with more experience of these types of bows have more and better info...
