Thanks guys!
That's the kind of tip I need. Before I added the oak belly, I took the ash core down do just 1,5 growthrings, so that alone is probably not more than 15-20#. I was kind of going for the hornbow-ratio of sinew-ash-horn/oak. Hoping I won't have to take away too much of the oak belly, because as you say, the ash probably won't be able to take the stress. So I'm kind of stuck with having to finish tillering it before the oak gets too thin. The bow has, in the meantime, undergone two stages as a selfbow, plus having a glass fiber back, so I'm prepared for the worst. I'll just have to finish it and see how it goes, and try to learn the most I can from it.
