One thing that might help you on that, I did several a few years ago, but the string will approach different angles to that recurve as it unfolds, When you first start to draw it there wont be much pressure, but as different parts of the limbs approach 90 degrees that potion of the limb will suddenly have a lot more pressure, you almost have to tiller each section at it's close to 90 degree position, or just pull on the tip by hand and get your self a little bend going that way before you actually string it. Curious to see how it comes out, they are very challenging. Steve
