I'm not a board bow guy, and I was gonna let one of 'em answer this for accuracy sake, but here's what I would do. Floor tiller to get each limb bending 4 to 5 inches. Try for an even amount of bend in each for the force you put on them. Then, if you have a tiller tree, pull it on the long string on the tiller tree. Pull to 4 or 5 inches, lock it in and check the limbs against each other. If one is stronger than the other take wood off until it matches the other Look for flat spots on that limb where it's not bending much. Take wood off in that or those spots. If the limb is bending nicely just stronger, take wood off from fade to tip. Once that limb is even with the other at 4-5 inches, check the tiller with a 4-5 inch straight edge on each limb. If the gap is nice and even for a ways and then increases at a spot, mark that spot and don't remove wood there. Find where the gap decreases and that is where you will remove wood until the gap is even, or close from fade to tip (really last 4-5 inches of the limb should be flat as you want the tips a good bit stiffer). Now check this corrected limb against the other. It should be a little weaker now, so, do the same on the other limb, taking wood off the flat spots until it matches the other limb in strength and shape. Once both limbs are even and bending good at 5 inches, pull it to 6 inches and do the same thing again. Keep both limbs even in weight and the gap even with the straight edge. Make sure your long string is just long enough to string the bow, you don't want a lot of slack. Get it braced at 3-4 inches when you feel comfortable you can brace it (bending good 4-5 inches or so evenly). Now just keep creeping up in draw length an inch or 2 at a time checking the limbs against one another and their shape. Easy peasy.
Once I have it braced at 5-6 inches, I want an even shape at brace, both limbs equal strength and no flat spots or hingy spots. If I can get it right at brace it will be very close the rest of the way, meaning I should be able to take wood off the entire limb rather than just one spot. If a flat spot or hingy spot shows itself, it should be very minor work in dealing with it. Hope that's helpful.
