Mark, I've never dealt with yew...but I have dealt with osage with a lot of propellar and dips and curves. We use a form that can be used to add both reflex and to straighten a bow. By using dry heat (heat gun), first clamp the bow in the middle of the form at the handle. Heating about a 6" section at a time starting at the fades, use clamps and shims to rotate the limb around and remove propellor. By using c-clamps to clamp near an edge (not center of limb), you can start to rotate the limb removing the propellor. If the bow is out of line where the tips aren't lining up center with the handle, secure the limb at the point just before the out of alignment starts by putting a fulcrum shim under the edge of the limb and clamping to the bottom of the form. The handle will also have to be shimmed up off the bottom of the form to accomplish this. You can then use another clamp out toward the tip and crank the tip down to align the overall limb. Go past where you need the tip to end up, because it won't hold all the adjustments you're making. Remember you have to really get the wood hot before you try and bend it. But keep that gun moving, easy to burn the wood if you hold the gun still in one spot. Ask anyone on here, I'm good at burning wood!
Work a little way down the limb at a time making adjustments as you go. Very difficult to explain this only with words, but I hope I'm making some sense!
