Ok, well, we are getting some more necessary info. Boo belly huh? You didn't tell us that important thing before!
This requires a totally different approach than a "all wood bow". Bamboo is not wood, by the way...
Since this bow has 4" of reflex, I still need to see an unbraced picture before I can judge the tiller. If the reflex is located AT the presumed 'hinge', you have a problem. Unbraced profile should match the full draw profile of any bow. 59" is also pretty short, at least for a 28" draw length.
As PatM said, since there is round, raw bamboo on the belly, you cannot tiller this bow the conventional way. You can only side-tiller a little bit, but not much. With such a bow, it is essential that you pretiller the backing, pretiller the core, AND pretiller the belly bamboo! You must pretiller all laminates before the glue up.
