All Wood Tri Lam Longbow?

[Jeremy]

Mr Weed, tillering depends on how it's put together.  Mostly I've put a little under 1/8" lam in the center - tapered or not - and a 1/4" lam on the belly.  Add in a 12-14" 'power lam' in the handle area and tiller like you would any self bow.  
The bows that are laid up just like a glass lam with 3+ thin tapered wood lams you just finese tiller by trapping the limbs or reducing width... or so I've heard
