I first saw the pulley method on youtube and I love the idea but I don't have a 2 by four or pulley or anything really lol which is kind of nutty so basically I ended up tillering using my body only. Sat on the floor, braced the handle on my foot, straighten my leg and pulled the string back and forth checking for bend (this is when flexibility comes in handy). It bends pretty evenly considering the flaws in the wood. There's slight limb twist but nothing worrying.
