heres what I was mentioning dean on how to match the one limb a lil better and closer to the other one....I would just try to get the tip close to the same where the other tip is in the limb and leave most of the dips...I wouldn't try to correct those dips or even put too much heat to em cus they have a tendency to wanna check or crack there if you try and put to much heat to em or try to force them to move and straightening them out.
if I cant use a form this is what ill do...just a 2x4 with a chalk line snapped down it. you can even move string tracking some if its only a little ways off by using your chalk line as a guide. heres a mock setup with a stave from the side on two 2x4's to give it 3" reflex and leather placed under so as not to ding the back. you can see the left limb needs a lil "push" to match the right. this is a floor tillered blank on it.
and heres where I put a shim in it to get the left limb matched up to the right
heres a closer view of the shimed area and that limb,and notice the chalkline
and heres a view from the long ways,and you can see that the handle and both tips are aligned on center
if this doesn't help you maybe itll help someone else who sees this
