First off don't draw it that far till you get the tiller straightened out, the belly of that knot from what i can see should be flat not bulging out, you have a lot of work getting the left limb balanced with the one with the knot work the mid limb where the knot is use a gizmo or a short straight edge, with that stave tiller should be close to even at brace, exercise the limbs after you scrape the limbs to about 15" no more till it's balanced out, but get them balanced out
